SERVICE PROGRAM MODE
[I]: Error Logging
The ten latest engine errors are logged. The counters go up every 200 prints. For
example, if the counter shows 10, the error occurred somewhere between print
numbers 2,000 and 2,199.
The errors included here are:
• Paper Feed Jam
• Transport Jam
• Paper Exit Jam
• Fuser Reload Error (could not return to the 'ready to print' temperature)
• Fuser Heater High Error
• Fuser Heater Low Error
• Synchronizing Pulse Error (for the laser)
• Polygon Motor Error
• Main Motor Error
• High Voltage Error (high voltage power supply)
The log is stored in the EEPROM and can be cleared using counter clear in the
service program mode menu.
[J]: Diagnostic Error Logging
The ten latest errors are logged. The log is stored in the NVRAM and can be
cleared by 'Diag clear' in the service program mode menu. When the printer control
board is replaced and the old NVRAM is installed on the new board, the diagnostic
errors should be cleared because these errors occurred with the old printer control
board.
e.g. 0 x 1010
[K]: Print Log Frame
This frame is drawn a sixth of an inch (4.2 mm) from the paper edges. The
registration is adjusted in the factory. If the registration has drifted, adjust the sub
scan or the main scan (see "Replacement and Adjustment - Print Registration
Adjustment").
