Fuser Solenoid Adjustment - Lexmark 7462 series Service Manual

Fuser solenoid adjustment

Perform the fuser solenoid adjustment whenever you replace the fuser solenoid. Adjust the fuser solenoid while
installed in the printer. Adjust the screw on the eccentric mounted on the solenoid housing to provide an air
gap between the rear of the solenoid stator and the solenoid armature. The solenoid air gap for all models is
4.5 mm ± 0.1 mm.
Gap adjustment
The gap adjustment allows you to increase the minimum gap between sheets of paper as they are fed through
the printer. This adjustment reduces the printer overall performance, such as pages per minute, but can help
in reducing the amount of curl of some printed media, thus improving media stacking in the output bin.
1
Enter the Diagnostic Mode.
2
Select Ep Setup from the Diagnostic Menu.
3
Select Gap Adjust.
4
The range of the GAP adjustment is 0 to 255. Adjust the gap setting by using the Menu button to select the
value. If GAP=0 displays, it indicates a factory setting to minimum gap. Select a value and run several copies
of the media that displays a curl problem. It may take several tries before improvement is noticed.
Note: This setting has no effect when duplexing.
Removal procedures
Keep the following tips in mind as you replace parts:
•
Some removal procedures require removing cable ties. You must replace cable ties during reassembly to
avoid pinching wires, obstructing the paper path, or restricting mechanical movement.
•
Remove the toner cartridges, imaging unit, and media tray before removing other printer parts. The imaging
unit should be carefully set on a clean, smooth, and flat surface. It should also be protected from light while
out of the device.
•
Disconnect all external cables from the printer to prevent possible damage during service.
•
Unless otherwise stated, reinstall the parts in reverse order of removal.
•
When reinstalling a part held with several screws, start all screws before the final tightening.
