Media picks but stops halfway through the printer
| FRU | Action |
|---|---|
| Input/duplex sensors (under print cartridge assembly) Input sensor (manual) | Make sure the input sensors are working properly. Check for a broken or stuck flag on the input sensors. Make sure the cables are seated on the controller card at J23 (Tray 1 input) and J20 (manual input). Check for about +5 V dc on pin 6 at J23 (Input/duplex sensor) and pin 3 at J20 (Input sensor). • If correct, replace the input paper feed sensor. • If these voltages are not correct, replace the controller card. |
Media never picks
| FRU | Action |
|---|---|
| Paper feed (pick tires) tray 1 Paper feed (pick tires) tray 2 Media drive ASM Media feed clutch ASM Manual feed clutch ASM P/U and manual feed solenoid ACM drive shaft |
Open the left cover, and verify that the solenoids and clutches are functioning when an attempt is made to feed the media. Make sure the rubber tires on the ACM are installed and clean. Replace the tires, ACM drive, clutch assemblies, solenoids, or drive shaft as necessary. |
Media occasionally mispicks or picks multiple sheets at once
| FRU | Action |
|---|---|
| Tray 1 Tray 2 (option) |
Check tray for media catch points. If the sheet being fed stops momentarily, the ACM applies additional vertical force, causing additional sheets to feed. Do not mix media types in one tray. |
| Paper pick tires (Tray 1 or tray 2) | Check the tires in the ACM assembly for signs of wear or damage. Replace the tires as necessary. |
| ACM clutch complete bill of material (CBM) Manual feed clutch CBM Media feed clutch ASM (tray 1 only) Manual feed clutch ASM |
Open left cover, and observe the solenoid and clutch actions at the ACM and manual feed shafts as a print job is attempted. Replace the faulty part. |
| Controller card P/U and manual feed solenoid ASM. | Disconnect the solenoid cable at J21 on the controller card. Measure the resistance across cable pins 1 and 2 and then pins 3 and 4. • The resistance should be 180–250 ohms. • If it is not, replace the solenoid assembly. • If the resistance is 180–250 ohms, check the controller card. See “Controller card service check” for more information. Replace controller card as necessary. |
