Description: Paper was sensed at the manual bypass sensor, but not at the main paper feed/toner cartridge present sensor.
Remedy: • Load paper in the manual bypass or remove the jam from the manual bypass. • Make sure the main paper feed/toner cartridge present sensor actuator is not broken, improperly installed or stuck with paper debris. • Perform the “Sensor test” to check proper operation of the sensor. • If the sensor works properly, the problem is likely associated with the system board. • If the paper path and sensor actuator are clear and working properly, and the problem persists, replace the HVPS/ LVPS. Note: This sensor is a component of the HVPS/LVPS.
Code: 02
Display: Document Jam
Description: Paper was sensed at the ADF registration sensor, but not at the ADF scan sensor.
Remedy: • Make sure the ADF scan sensor actuator is not broken, improperly installed or stuck with paper debris. • If the paper path and sensor actuator are clear and working properly, replace the scanner assembly.
Code: 03
Display: Door Open
Description: Front or rear cover is not securely latched.
Remedy: • Close the front toner cartridge access cover until it locks. • If the message does not clear, perform the “Sensor test” to check proper operation of the switch. • If the switch works properly, the problem is likely associated with the system board. • If the switch does not work in the test, make sure the cover open actuator is working properly. When the cover closes, the cover should push the actuator, causing the cover open switch on the HVPS/LVPS to close. Note: This process is viewable with the right cover removed. • If all moving parts appear to be working correctly, and the messages does not clear, replace the HVPS/LVPS.
Code: 04
Display: Fuser Error
Description: Problem in the fuser unit.
Remedy: • Make sure CN1 and CN7 on the HVPS/ LVPS are properly connected. • Check CN1 on the HVPS/LVPS for proper voltage. • If the voltage is correct, replace the fuser. • Otherwise, replace the HVPS/LVPS.
Code: 05
Display: Load Bypass
Description: No document loaded in the manual bypass.
Remedy: Load print media into the manual bypass and try again.
Code: 06
Display: LSU Error
Description: A problem in the LSU (laser scanning unit).
Remedy: • Make sure all cables are properly connected to the printhead. • If correct, replace the printhead.
