4060-xxx Smart contact assembly service check Note: If you are unable to clear a "32-Unsupported Cartridge" User Error message, be sure a Lexmark T63x 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. Make sure the smart cable is properly connected to J19 on the system board. Check the print cartridge for 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 system board. FRU 1 Smart contact assembly System board Action Check the voltage on the smart cartridge contact. The voltage measures approximately +3.8 V dc when not writing data to the system board. If data is being written, the voltage measures approximately 0 V dc. If incorrect, disconnect the cable from J19 on the system board and check the voltage on J19-1.
