For an ‘Unrecognized Cartridge error’ message first ensure the 2 electri-
cal integrated chip contacts on the rear of the cartridge have been
penetrated. Replace the cartridge to verify problem.
Unrecognized Cartridge Failure Analysis Steps:
1. Be sure the cartridge is the correct cartridge for your printer
model. Your printer will not work with cartridges from other models.
Remember, the printer is reading the value programmed into the
chip on the cartridge, it is not actually detecting the cartridge type.
Replace the cartridge to verify a failure.
2. Check MSB version. Select Utility Menu - Service Menu - About.
