Insert Cartridge or Close Door This message displays when the printer front door is open or the print cartridge is missing. If this message cannot be cleared go to "Cover Open Switch/Cable Service Check" on page 2-42. 31 Defective Print Cartridge Error code 31 is displayed 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. 2-26 Service Manual
