Stop Wasting Needles: How to Reserve (Anchor) a Needle on the Brother PR1055X & PR670E Without Breaking Thread or Your Auto-Threader

If you have ever stood in front of your machine, heart racing as you hit “Embroider,” only to watch in horror as the needle bar moves to a position you specifically didn’t want it to, you know the unique frustration of machine embroidery. It’s a feeling of betrayal—you thought you and the machine were on the same page.

On Brother PR multi-needle machines, the Reserve Needle feature (often colloquially called the Anchor Needle due to its icon representation) is the handshake agreement between you and the computer. It is one of the most powerful workflow settings available, yet it remains one of the most misunderstood.

This white paper-style walkthrough covers the nuances of both machine generations shown in the video: the workhorse Brother PR670E (6-needle) and the flagship Brother PR1055X (10-needle). We won’t just tell you which buttons to press; we will explain the mechanical logic behind them, how to use the PR1055X’s sophisticated per-needle speed limiting to handle notoriously difficult metallic threads, and how to create a safety protocol that protects your garments and your sanity.

Reserving (Anchoring) a Needle Bar on Brother PR1055X & PR670E—What It Really Does in Real Life

To master this feature, you must first understand the machine’s default "brain." By default, Brother PR machines are designed to be helpful: they look at the colors in your digital design and automatically assign them to needle bars based on what is most efficient or what was used last.

When you Reserve (or Anchor) a needle, you are effectively overriding this automation. You are telling the machine’s operating system: “Needle Bar #X is physically owned by this specific thread color until I say otherwise. Do not attempt to optimize it, change it, or overwrite it.”

In a high-volume production environment, this is critical. In the video, Jeanette explains the most common commercial use case: keeping Black and White permanently loaded. Why? Because nearly every logo or design uses them for outlines or underlay.

The trade-off is a calculation of inventory versus speed:

• On a 6-needle PR670E, reserving two needles (Black/White) leaves you with only four flexible needles. This is a tight squeeze for complex shading.
• On a 10-needle PR1055X, reserving two needles leaves you eight flexible needles—still more than enough for most corporate logos.

Cognitive Note: While the manual calls this function “Reserve,” the UI uses an Anchor icon. If you are looking for "Reserve" in the menus, you won't find it. Look for the anchor.

The “Hidden” Prep Before You Touch Settings: Thread Plan, Needle Choice, and a Clean Baseline

Before you touch a single pixel on the screen, you must perform a physical "Pre-Flight" check. 80% of embroidery failures—bird nests, shredded thread, and broken needles—are caused by physical setup errors, not software settings.

1. Physical Thread Audit

Confirm tactilely which needle bar holds your target thread. Don't just look; touch the spool on Needle #1 and trace the path. It is incredibly common to reserve Needle #1 on the screen while physically having the black thread on Needle #2. The machine cannot see your thread rack; it blindly trusts your input.

2. Needle Geometry Selection

The video mentions that Brother machines generally perform best with standard 75/11 embroidery needles. This is the industry "sweet spot"—the eye is large enough to reduce friction (heat), but the shaft is thin enough to avoid punching massive holes in knits. Jeanette mentions a preference for 65/9 for finer detail.

• Experience Tip: If you reserve a needle for Metallic Thread, swap that specific needle to a Topstitch 80/12 or a specific Metallic Needle. The larger eye prevents the rough metallic foil from stripping off the core wire.

3. Tension Check (The "Floss" Test)

Before locking a needle in, check its tension. Pull the thread through the needle eye. You should feel a smooth, consistent resistance, similar to pulling dental floss between your teeth. If it pulls with zero resistance, your tension brings are open or clogged with lint. If it jerks, the thread is caught.

4. Machine State

Always start this process from the Main Home Screen. Jeanette exits out of all designs to ensure the machine isn't holding onto cached data from a previous job.

Prep Checklist (Verify Physical State):

• Inventory: Confirm the "Permanent" spool (Black/White) is seated securely on the spool pin.
• Path: Trace the thread path to ensure it hasn't jumped out of the tension disk checkspring.
• Needle: specific needle size matches thread weight (e.g., 75/11 for Rayon 40wt, 80/12 for Metallic).
• Consumables: Ensure you have the correct stabilizer (backing). For stretchy performance wear, ensure you are using a Cutaway stabilizer, not Tearaway, to support the permanent stitches.
  

Find the Needle Attribute Setting on Brother PR670E & PR1055X (It’s Always on Page 3)

Navigating the Brother interface can be intimidating for beginners because there are so many icons. However, the path to the Needle Attribute Setting is consistent across machines shown in the video.

1. Locate the "Paper" Icon: From the home screen, tap the settings icon that looks like a piece of paper.
2. Navigate to Page 3: Use the forward arrow keys.
   • On the PR670E: You are looking for screen 3 of 6 (approximate).
   • On the PR1055X: You are looking for screen 3 of 10 (approximate).
3. The Target: Tap the button labeled Needle Attribute Setting.

Think of this screen as the "BIOS" or "Control Panel" for your needle bars. This is where you tell the mechanical arms how to behave—assigning colors, setting speed limits, and engaging the anchor.

Lock a Permanent Color on the Brother PR670E: The “Set” Button Creates the Anchor Icon

On the Brother PR670E, the workflow requires a specific "confirmation" step that often trips up new users. Just selecting the color isn't enough; you must commit the change.

Step-by-Step Execution:

1. Select the Bar: On the Needle Attribute screen, tap the row corresponding to the needle you wish to reserve (e.g., Needle #3). The entire row will highlight in blue.
2. Assign the Color: Tap the spool icon/color palette. Find your specific color code (e.g., Brother Black 900) and select it.
3. The Critical Step: Press the SET button.
4. Visual Verification: Look for a small blue anchor icon appearing next to the needle number on the list.

Sensory Cue: If you do not see that blue anchor, the machine has NOT locked the needle. If you exit now, the machine will likely swap that color on the next design load.

A production-minded tip (so you don’t paint yourself into a corner)

If you reserve Black and White on a 6-needle machine, you have reduced your color flexibility by 33%. Ideally, this is done when you have a run of 20+ shirts with simple logos.

If you are running volume jobs like this, your bottleneck is rarely the machine—it is the hooping process. While the machine stitches your reserved colors, you should be checking your workflow. Many shops utilize hooping stations to ensure the next garment is perfectly aligned and ready to go the second the machine finishes. This parallel workflow is the secret to profitability.

The PR1055X Advantage: Reserve the Needle *and* Cap Its Speed for Metallic Thread

The Brother PR1055X introduces a game-changing feature for specialty threads: Independent Needle Speed. This is the solution to the nightmare of metallic thread. Metallic thread is stiff, prone to twisting, and generates high friction heat that snaps the thread at high speeds.

Previously, you had to slow the entire machine down to accommodate one flashy color. On the PR1055X, you can throttle just the problematic needle.

The Anchor & Speed Workflow:

1. Navigate: Go to Needle Attribute Setting (Page 3).
2. Select: Tap the needle row (e.g., Needle #3).
3. Assign Color: Select your thread color (e.g., Dark Brown or Gold).
4. Toggle Anchor: Tap the Anchor Button (located at the bottom right of the screen in the video). Note that unlike the PR670E, this is often a direct toggle.
5. Adjust Speed:
   • The global max speed might be set to 1000 spm (stitches per minute).
   • Tap the speed adjustment arrows for that specific needle to lower it.
   • Sweet Spot: For metallic threads, Jeanette demonstrates reducing this to 600 spm.

Why 600 SPM? At 1000 SPM, the needle creates friction heat that can melt the polyester core of metallic thread. At 600 SPM, the needle stays cool enough to maintain integrity, preventing those "mystery breaks."

Warning: Respect the Danger Zone. The needle bar case moves laterally with significant force, and the needles themselves are sharp projectiles if they break at speed. Never attempt to thread a needle or clear lint while the machine is in "Active" mode. Always hit the "Lock" button on the screen or power down before putting your hands near the needle case.

Verify the Reserve/Anchor Is Actually Working (The Embroidery Screen Tells the Truth)

Trust, but verify. The settings screen says one thing, but the Embroidery Screen (the "Ready to print" screen) is the final authority.

After setting your anchors and loading your design:

1. Look at the color sequence list on the right side of the screen.
2. Locate your reserved needle color in the list.
3. Visual Check: The reserved needle should appear "Grayed Out" (dimmed) and display the anchor icon next to it.
   • Normal Needle: Brightly colored, editable.
   • reserved Needle: Dimmed, locked.

This "Grayed Out" status is the machine’s way of communicating: "I acknowledge this needle is locked. I will bypass my internal optimization algorithms and use this needle exactly as instructed."

Protect Your Brother Auto-Threader: When to Disable Automatic Threading for One Needle

The Brother automatic needle threader is a marvel of engineering, but it relies on strict tolerances. It expects a standard needle (75/11) with a standard eye position.

In the PR1055X section of the video, Jeanette highlights the Automatic Threading toggle icon. You should consider turning this OFF for a specific needle if:

1. Size Mismatch: You are using a very fine needle (65/9 or 60/8). The threader hook might force itself into the smaller eye, potentially scratching the hook or bending the needle.
2. Specialty Needle: Short-shank or Wing needles.
3. Thick Thread: 12wt or 30wt cotton thread might be too bulky for the threader hook to grab cleanly.

The Strategy: Disable the auto-threader for that specific needle bar in the Needle Attribute settings. When the machine requests a thread change, you manually thread that one needle. It takes 10 seconds, but it saves you a $300 service call to replace a bent threader mechanism.

Removing the Reserve/Anchor Cleanly: PR670E Uses Reset, PR1055X Uses Toggles

A common panic moment occurs when a user finishes a batch of jobs and tries to load a new colorful design, only to find the machine refusing to use Needle #1 for anything other than Black. You must "release" the reservation.

On the Brother PR670E (6-needle)

The command is "Reset."

1. Return to Needle Attribute Setting.
2. Select the reserved needle row (verify the anchor icon is there).
3. Press the RESET button.
4. Verification: The anchor icon disappears instantly.
   

On the Brother PR1055X (10-needle)

The command is a "Toggle."

1. Return to Needle Attribute Setting.
2. Select the reserved needle row.
3. Tap the Anchor Icon button to toggle it off.
4. Clean Sweep: If you also limited the speed or disabled the auto-threader, ensure you toggle those back to default settings as well.

Jeanette demonstrates the icons disappearing one by one. Once the row looks "plain" again, the specific needle returns to the general pool of available needles for auto-assignment.

Setup Checklist: The “Reserved Needle” Workflow That Stays Fast *and* Reversible

Before you commit to a production run, run through this mental or physical checklist. This prevents the "start, stop, fix, restart" cycle that kills efficiency.

Setup Checklist (Execute right before pressing Embroidery):

• Icon Check: In Needle Attribute Setting, does the target needle have the Anchor icon?
• UI Confirmation: On the Embroidery Ready screen, is the needle number Grayed Out?
• Speed Safety: If running Metallic/Delicate thread on PR1055X, is the speed cap (e.g., 600 spm) visible?
• Physical Match: Is the correct thread spool actually on the correct pin? (Don't laugh—check it.)
• Hoop Clearance: Does your selected hoop size match the actual hoop on the machine? (The video highlights adjusting from a 5x5 default).
  

Troubleshooting the “Scary” Stuff: Grayed-Out Anchor Icon, Metallic Breaks, and Threader Risk

Even with perfect setup, things go wrong. Here are the three most common issues users face, as identified in the video comments and field experience.

Symptom A: “My anchor icon is grayed out on my PR1055X—I can't click it!”

This is a terrifying moment where the machine seems to lock you out.

• Likely Cause: You haven't selected a valid context for the anchor.
• The Fix:
  1. Go to Needle Attribute Setting.
  2. Ensure you have tapped the specific Needle Row so it is highlighted in blue.
  3. Ensure a Thread Color is selected. You cannot anchor a "null" value.
  4. If still stuck, check if the machine is in the middle of a pattern or "Resume" mode. Return home and start fresh.

Symptom B: Metallic thread shreds or breaks every 2 minutes.

• Likely Cause: Heat and friction.
• The Fix (PR1055X): Reserve the needle and cap speed at 600 spm.
• The Fix (Generic): Use a larger needle (Topstitch 80/12) and a thread net to prevent the metallic thread from twisting off the spool.

Symptom C: "I'm afraid to use the auto-threader on my Micro-Needle."

• Likely Cause: Valid fear of mechanical damage.
• The Fix: Disable Automatic Threading in the attribute settings. It is better to thread manually than to force a mechanical threader into a size 60/8 eye.
  

Decision Tree: Should You Reserve Black/White, Reserve Metallic, or Keep All Needles Flexible?

Use this logic flow to determine the best setup for your current workload.

Start Here: What is your primary output for the next 4 hours?

Scenario 1: Uniforms, Corporate Polos, Name Tags.

• Requirement: High repetition, same output colors.
• Action: Reserve Black and White.
• Why: You will save 2 minutes per job by not swapping common spools. If you want to increase speed further, efficient handling is key—professionals often look into hoopmaster station systems to standardize placement.

Scenario 2: One-off Custom Designs (Full Color).

• Requirement: Maximum flexibility.
• Action: Do NOT Reserve (especially on PR670E).
• Why: You need every needle available to avoid manual thread changes during the print.

Scenario 3: Designs involving Metallic or Glow-in-the-Dark thread.

• Requirement: Special handling for one delicate thread.
• Action: Reserve & Speed Cap.
• Why: Dedicate "Lane #10" as your "Slow Lane." Use PR1055X speed limiting (600 spm).

Scenario 4: High Volume Production (50+ items).

• Requirement: Speed and Ergonomics.
• Action: Reserve core colors.
• Upgrade Path: If your machine is fast but your hands hurt from clamping, consider upgrading to magnetic embroidery hoops for brother. They reduce wrist strain and are faster to load, keeping up with the machine's efficiency.
  

Warning: Magnetic Safety. Professional magnetic hoops (like Mighty Hoops) snap together with immense force (up to 30lbs of pressure). Keep fingers clear of the edges to avoid severe pinch injuries. Persons with pacemakers should consult their doctor before handling high-gauss magnets.

The Upgrade Path That Actually Makes Sense: When Settings Aren’t the Bottleneck Anymore

Optimizing your "Reserve Needle" settings is a Level 1 efficiency hack. It saves you software time. But once you master this, the bottleneck physically moves to your hands. You will find yourself waiting on the hoop, not the needle.

Here is the hierarchy of upgrades for the growing embroidery business:

1. Level 1: Stability & Ergonomics (The Hoops)
   The standard plastic hoops work, but they require significant hand strength and can cause "hoop burn" (friction marks) on delicate fabrics.
   • Solution: brother pr1055x hoops in magnetic variants. By holding the fabric with magnetic force rather than friction, you eliminate hoop burn and clamp faster.
   • Pro Choice: Many shops standardize on mighty hoops for brother pr1055x because the self-aligning magnets essentially "hoop themselves," drastically reducing setup time between shirts.
2. Level 2: Workflow (The Station)
   If you are embroidering left-chest logos, eyeballing placement is risky.
   • Solution: A magnetic embroidery hoop combined with a hooping board allows you to prep the next shirt while the current one stitches.
3. Level 3: Capacity (The Machine)
   If you are on a PR670E and find yourself constantly reserving 4 needles and swapping the last 2, you have outgrown the hardware.
   • Solution: This is the trigger point for upgrading to a 10-needle or 15-needle machine (like the PR1055X or SEWTECH multi-needle solutions). The jump to 10+ needles allows you to keep a full spectrum of colors and specialty threads anchored permanently.
     

Operation Checklist: The “No Regrets” Run—What to Confirm Before You Walk Away

Once the machine starts, you want to be able to walk away and do other work. Run this final check to ensure the machine doesn't need a babysitter.

Operation Checklist:

• Gray is Good: Confirm the reserved needle is grayed out on the screen.
• Spool Secure: Give the thread spool a tiny tug to ensure it hasn't looped around the pin.
• Speed Check: If using Metallic, glance at the screen—is the speed limit active?
• Manual Ready: If Auto-Threader is disabled, have your tweezers or manual threader tool nearby.
• Exit Strategy: If this is a one-off job, put a sticky note on the screen: "RESET ANCHORS AFTER JOB" so you don't confuse yourself tomorrow.
  

A final “watch out” from the field

The most common support call regarding "broken colors" usually turns out to be a needle that was reserved three weeks ago and forgotten. The machine is obedient; it will hold that reservation until the end of time.

If you want the fastest day-to-day workflow on a PR1055X, reserving one needle for Black and one for White is a solid professional baseline. And if you stitch metallic often, dedicating a "Slow Lane" via the Reserve feature doesn't just save thread—it makes you look like the master of your machine, rather than its servant.

FAQ

• Q: How do I find the Brother PR1055X “Needle Attribute Setting” menu to reserve (anchor) a needle?
  A: Open settings from the Home screen and go to Page 3 to reach “Needle Attribute Setting.”
  • Tap the settings icon that looks like a paper sheet on the main Home screen
  • Press the forward arrows until you reach Page 3 (PR1055X is around screen 3 of 10)
  • Tap “Needle Attribute Setting”
  • Success check: The needle list/control panel for colors, anchor, and per-needle options is visible
  • If it still fails… Exit out of any open design back to the main Home screen so the machine is not holding a previous job state
• Q: How do I reserve (anchor) a needle color on a Brother PR670E so the blue anchor icon actually appears?
  A: On Brother PR670E, the anchor will not lock until the SET button is pressed.
  • Tap the target needle row so the whole row highlights blue
  • Choose the thread color from the spool/color palette
  • Press SET to commit the change
  • Success check: A small blue anchor icon appears next to that needle number on the list
  • If it still fails… Re-check that the correct needle row is selected (highlighted) before pressing SET
• Q: How can I confirm the Brother PR1055X or Brother PR670E reserved (anchored) needle is truly locked before embroidery starts?
  A: Verify on the Embroidery “Ready” screen, not only in settings, because the Embroidery screen is the final authority.
  • Load the design after setting the reserved needle
  • Look at the color sequence list on the right side of the Embroidery screen
  • Identify the reserved needle entry in that list
  • Success check: The reserved needle appears grayed out (dimmed) and shows an anchor icon next to it
  • If it still fails… Return to Needle Attribute Setting and re-apply the reserve/anchor, then reload the design
• Q: Why is the anchor icon grayed out and not clickable on a Brother PR1055X Needle Attribute Setting screen?
  A: This is common—Brother PR1055X usually won’t allow anchoring until a valid needle row and thread color are selected.
  • Tap the specific needle row until it highlights blue
  • Assign a thread color to that needle (you cannot anchor a “null” color)
  • Return Home if the machine is in a resume/in-progress state, then re-enter Needle Attribute Setting
  • Success check: The anchor control becomes available and the anchored status displays for that needle
  • If it still fails… Confirm the machine is not mid-pattern and start from the main Home screen with no design active
• Q: How do I stop metallic thread from shredding or breaking on a Brother PR1055X using Independent Needle Speed?
  A: Reserve that metallic needle and cap only that needle’s speed to about 600 spm so heat/friction drops without slowing the entire job.
  • Assign the metallic thread color to a dedicated needle in Needle Attribute Setting
  • Toggle the anchor for that needle so it stays dedicated to that thread
  • Lower that needle’s speed limit (example shown: 600 spm even if global max is 1000 spm)
  • Success check: Metallic thread runs longer without “mystery breaks” and the machine does not need constant re-threading
  • If it still fails… Swap that reserved needle to a Topstitch 80/12 or a Metallic needle and add a thread net to reduce twisting
• Q: When should I disable Automatic Threading on a Brother PR1055X to protect the auto-threader mechanism?
  A: Turn off Automatic Threading for that specific needle when needle size/type or thread thickness makes the threader risky.
  • Disable Automatic Threading for that needle in Needle Attribute Setting
  • Manually thread that needle when the machine calls for a thread change
  • Use this especially with very fine needles (65/9 or 60/8), specialty needles, or thick thread (like 12wt or 30wt)
  • Success check: Manual threading works smoothly and the auto-threader is not forced or scraping/bending anything
  • If it still fails… Return that needle to a standard 75/11 for auto-threading and confirm the setup matches the machine’s expectations
• Q: What is the safest way to work around the Brother PR needle bar case when reserving needles or clearing lint?
  A: Never put hands near the needle bar case while the machine is active—lock the machine on-screen or power down first.
  • Press the on-screen Lock function (or power down) before touching near needles or the needle case
  • Wait until all motion fully stops before threading, cleaning, or tracing thread paths
  • Keep fingers clear of moving lateral needle bar mechanisms and sharp needles
  • Success check: The machine is visibly stationary and cannot start stitching while hands are in the needle area
  • If it still fails… Stop the job, exit to a safe state, and only then continue setup—do not attempt “quick fixes” with the machine active
• Q: When do magnetic embroidery hoops make sense after optimizing Brother PR1055X/PR670E reserved needle workflows?
  A: If hooping speed, hoop burn, or hand strain becomes the bottleneck, magnetic hoops are the next practical upgrade after Level 1 settings optimization.
  • Diagnose the bottleneck: Track whether the machine is waiting on hooping more than thread changes
  • Try Level 1 first: Reserve core colors (and speed-cap metallic on PR1055X) to reduce stoppages
  • Move to Level 2 tools: Use magnetic hoops to reduce clamp time and minimize hoop burn on delicate fabrics
  • Success check: Hooping becomes faster and more consistent, and garments show fewer friction marks
  • If it still fails… If frequent manual thread swaps remain the limiting factor on a 6-needle workflow, consider moving to a higher-needle-count machine for capacity rather than more settings tweaks
