Smart Contact Assembly Service Check - Lexmark Infoprint 1332 User Manual

Smart contact assembly service check

Note: If you are unable to clear a "32-Unsupported Cartridge" User Error message, be sure an
IBM 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.

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. The voltage
measures approximately +5 V dc.
• If incorrect, replace the system board.
• If correct, replace the smart cartridge contact assembly.
