Question about Xerox Phaser 8400 Laser Printer
From the service manual:
The printhead is stuck in the tilt position by the tilt arms. The process motor gearbox
being out of sync can also cause this error.
1. Reboot the printer.
2. Verify the lock arms rotate correctly.
3. Check for spilled ink around the printhead.
4. Check the process motor gears for damage. Ensure the
process gears are correctly aligned and homed.
5. Verify the process gear box, process shaft, and drive
module shaft are at home position.
6. Verify the headtilt gear will engage, see the home
positioning procedure on page. You can manually
engage the headtilt gear.
7. Run the Tilt Axis Drive test.
8. Run the Process Motor test.
9. Run the Head Maintenance Clutch test, if the test fails
replace the clutch.
10.Run Wiper Drive test. If this fails inspect the wiper
Since posting all these test would be impractical, let me know if you need the service manual and I can send it your way. Thanks and please take a moment to rate as fixya.
