Description: Detected cover switch bounce. • Upper cover not fully closed. • Cover switch not functioning correctly.
Remedy: 1 Toner cartridge Make sure the toner cartridge is correctly installed and that the right and left cartridge tracks are not loose or broken. Make sure the cover closed switch activation tab on the toner cartridge is not broken and that the tab correctly activates the cover closed switch spring. 2 Cover closed switch/cable assembly Check the cover closed switch for proper mechanical operation. If incorrect, repair as necessary. Disconnect the cover closed switch cable from J8 at the system board and measure the voltage at J8-3. It measures approximately +5 V dc. If the voltage is incorrect, replace the system board. If the voltage is correct, check the voltage at J8-1. If the voltage measures greater than +1.0 V dc, replace the system board. If the voltage is correct, check the continuity between J8-1 and J8-3 on the cable. If no change in continuity occurs as the switch is activated, replace the hinge assembly. If the continuity changes as the switch is activated, replace the system board.

Description: Invalid refill, change cartridge
Remedy: The MFP detects a refilled Lexmark Cartridge Return Program print cartridge. Install a new print cartridge to clear the message.
Remedy: Error code 31 displays when the top front cover is closed and a defective print cartridge is detected. It may take the printer 10-20 seconds to determine if the print cartridge is defective. Depending on the setting of the Machine Class ID the printer may be allowed to print pages during this 10- 20 second interval. If pages are allowed to print, they are not reprinted once a good print cartridge is inserted. Note: This error indicates the printer was able to read the cartridge ID, but the ID did not pass the verification test. To pass the verification test, the ID read from the print cartridge must match the ID from the last “good” print cartridge or the same ID must be read from the print cartridge twice. The last “good” print cartridge ID is stored in NVRAM.
