This procedure assures that the printhead is the proper distance from the drum.
Make this adjustment after removing or replacing the printhead. If you cannot
use the PC diagnostics to assist with this procedure (due to security restrictions
at the customer site), then do the following: During the procedure allow the
printer to power up to its Ready state and then open the front panel to stop all
motor motion (the printhead will start to cool), quickly continue the procedure
at Step 4. When you finish the adjustment, close the front door, allow the
printhead to warm up and then check the adjustment.
1. Remove the top cover as described in the topic "Cabinet panels and
covers" on page 8-4.
2.
Start the PC-based diagnostics program. Refer to the topic "PC-based
diagnostics" on page 6-29. Activate the diagnostic's Printhead to
Drum Gap Adjustment (Hot) routine. The routine automatically
centers the printhead, and brings the printhead and drum to their
operating temperatures.
3. When the printer is ready, press Enter to stop the drum and begin the
gap adjustment.
