HP Printer Paper Pickup Assembly

Guangzhou Huilian Office Equipment Co., Ltd

1. Overview

The paper pickup assembly is the entry section of the HP laser printer paper path, located inside each paper tray (Tray 1 MPT / Tray 2 / Tray 3+). It grabs the top sheet from the stack, separates it from the rest, and feeds it into the registration area. A worn pickup roller or hardened separation pad is the number-one cause of 13.00 / 13.01 / 13.02 / 13.B2 class jam codes on HP LaserJet Pro and Enterprise models.

Core functions:

  1. Grab the top sheet from the stack
  2. Prevent second-sheet feed via separation pad/roller (anti-double-feed)
  3. Deliver the sheet smoothly to the pre-registration path
  4. Report tray-presence and paper-height signals to the DC controller

2. Working Principle

Components

Component Function
Pickup Roller Nitrile rubber face (Shore A 70±3), drops onto stack when tray lifts, rotates to drag top sheet
Separation Pad / Roller Static rubber pad or counter-roller that holds back the second sheet (anti-double-feed)
Feed Roller (Tray 2+) Secondary pair pulling sheet from pickup zone into registration
Paper Present / Lift Sensor Detects tray inserted and paper stack height; triggers pickup sequence
Pickup Actuator Arm White lever linked to DC board; lifts when tray inserted, confirms tray seat

Workflow

Step Action
1 Tray inserted → lift sensor + actuator arm flip → DC board arms pickup clutch
2 Pickup roller drops, rotates, drags top sheet only forward
3 Sheet passes separation pad/roller → second sheet held back (single-sheet guarantee)
4 Feed roller takes over, moves sheet to registration sensor (SR6)
5 If sheet fails to reach SR6 in time → 13.01/13.02/13.B2; if roller never turns → 13.00 "No pickup"

3. Core Technical Parameters

Parameter Typical Range Note
Roller material Nitrile rubber, Shore A 68-75° OD Φ18-24mm, M607 class RM2-1275
Separation pad Micro-porous rubber, harder than pickup M525 class RM1-6303-000CN
Drive Main motor → clutch → pickup shaft (Tray 2) M607/M608 use RM2-6771 assy
Sensor type Optical interrupter (lift) + micro-flag (actuator)
Paper weight 60-120 g/m² (plain); some Pro max 105g >120g → misfeed rate rises
Stack height ≤ tray fill line, ~250-500 sheets 75g Overload = pickup slip
Service life Roller 100k-150k pages; pad 50k-80k pages Replace as kit, not singly
Common spare P/N M525: RM1-6323-000CN (roller) / RM1-6303-000CN (pad) M607: RM2-1275 + RM2-6772

4. Common Error Codes

Code Display Meaning Root cause in pickup assembly
13.00.00 Paper jam in tray No pickup at all Tray not seated, actuator broken, clutch open, lift sensor dirty
13.01.00 Jam in tray 2 Picked but stopped before registration Roller glazed, sep pad worn, guide misalign
13.02.00 Jam in pickup area Skewed at pickup mouth Guides too tight, wrong fan direction, one-side roller wear
13.B2.D2 Jam in Tray 2 Paper not leaving tray in time Worn pickup roller + sep pad (M525/M552/M607 classic)
13.B2.D3/D4/D5 Same, Light/Heavy media Grip fails on special media Thick paper exposes weak grip earlier
13.B2.FF Power-on residual Tray 2 Actuator flag stuck at "paper present" Torn paper under flag, spring broken
60.0x Tray 2 overfilled Firmware sees tray-full or pickup anomaly RM2-6771 misseated, white tab off
41.03.xx Unexpected size Pickup timing drift → DC miscalc paper length Roller slip + dirty sep pad combo
Note: When 13.B2.D2 recurs, replace pickup roller + separation pad as a kit, not singly.

5. Troubleshooting

Common symptoms

Symptom Possible Cause
No pickup, 13.00 Tray not clicked in, actuator arm not flipping, clutch open
Repeated 13.B2.D2 on Tray 2 Pickup roller glazed + sep pad hardened (M525 textbook)
Double-feed (2 sheets at once) Separation pad lost porosity, must replace not clean
13.01 with curl Stack top damp (humidity), fan top 5-10 sheets out
60.0x false tray-full RM2-6771 white tab off pickup arm, RM2-6772 not locked

Six-step diagnosis

  1. Step 1: Hard reset: Unplug power cord, wait 60 seconds, plug direct to wall outlet to clear transient false jams.
  2. Step 2: Inspect tray and stack: Pull tray, confirm no staples, curl <5mm, height below fill line, guides snapped to size detent.
  3. Step 3: Spin pickup roller by hand: Should NOT free-spin 360° (clutch engaged); surface must feel matte, not mirror-smooth.
  4. Step 4: Water-clean only (no alcohol): Damp lint-free cloth, rotate roller, dry 2 min. Alcohol shrinks rubber. If pad pores gone → replace.
  5. Step 5: Check actuator: White lever left of RM2-6772 must spring back; black flag right side must drop when tray empty. Else replace RM2-6771 pickup assy.
  6. Step 6: Replace as kit: Roller + pad together (M525: RM1-6323-000CN + RM1-6303-000CN; M607: RM2-1275 + RM2-6772). Never replace roller alone on 100k+ page machines.

6. Replacement Guide

Tools: T-10/T-15 Torx, lint-free cloth, clean water, anti-static gloves

  1. Step 1: Power off, unplug, cool, remove Tray 2.
  2. Step 2: Open right door (M525/M552) or lower-access cover (M607).
  3. Step 3: Unlock separation roller lever → lift out separation assy (RM2-6772 class).
  4. Step 4: Lift side latch, slide pickup roller left → out (RM2-1275 / RM1-6323 class).
  5. Step 5: Insert new roller left-side first, snap right side; align blue tabs of sep assy, push in, lock lever.
  6. Step 6: Reseat tray, close door, boot → Diagnostic → Paper Path Test → 20-sheet Tray 2 print.
  7. Step 7: If panel tracks life, reset Tray 2 Roller Kit count.

7. OEM vs Compatible

Dimension HP Original Compatible
Rubber porosity Consistent micro-pore, Shore A 70±3 Often 76-82°, glazes after 20k pages
Separation pad life Retains anti-double-feed 50k+ pages Loses grip <15k pages → double-feed
Actuator tolerance 0.1mm mold match Tab offset → 60.0x false tray-full
Pickup life 100k-150k pages 25k-50k pages
Double-feed rate <0.1% >1% (main complaint)
Warranty HP / PartsOne channel Seller-dependent

8. FAQ

Q: Is 13.B2.D2 always a fuser or registration jam?
A: No. 13.B2.D2 specifically means paper did not leave Tray 2 in time — HP's own M525/M552 service note points to worn pickup roller + separation pad first, not fuser.
Q: Can I just clean the pickup roller instead of replacing?
A: On Pro M400 class under 30k pages, water-clean restores grip temporarily. On Enterprise M600+ past 80k pages, glazing is permanent — clean buys a week, replace is the fix.
Q: Why does double-feed happen even after new pickup roller?
A: Because the separation pad (not the roller) lost porosity. Pads are cheaper than rollers but wear faster; always replace pad with roller.
Q: What does "Tray 2 overfilled or roller issue" mean?
A: Firmware 60.0x on M607/M608 — usually the white actuator tab on RM2-6771 slipped off the pickup arm, or RM2-6772 sep roller not locked. Re-seat assy before swapping parts.
Q: Pickup roller free-spins 360° by hand — normal?
A: No. With tray out and clutch disengaged it may turn, but on M601-M606 class a free-spinning roller with tray inserted means clutch gear broken, not just worn rubber.
Q: Humidity makes Tray 2 jam — is it the roller?
A: Partly. High humidity waves the top sheets → pickup slips. Fan out top 5-10 sheets, store paper sealed. If jam persists after dry paper → roller/pad worn, not environment.
