Smart Contact Assembly Service Check
Note: If you are unable to clear a “32-Unsupported Cartridge” User
Error Message, be sure a Lexmark 4520 print cartridge is correctly
installed in the printer. The cartridge is easily identified by the
contact board on the right side rear of the cartridge. Install another
print cartridge before attempting to troubleshoot the printer. Check to
make sure the smart cable is properly connected to J21 on the
engine board. Check the print cartridge for any signs of damage or
improper installation of the smart chip. Also, be sure there is proper
contact between the smart chip on the cartridge, and the smart
contact assembly.
Service Tip: An intermittent “32-Unsupported Cartridge” User Error
Message can be caused by poor contact between the smart
cartridge contacts in the upper front cover and the smart chip. Also
check for proper seating of the smart cartridge cable to the engine
board.
