The procedure for using the service tool v4720 for resetting the ink absorber in a PGI-x50/CLI-x51 cartridge generation printer is the same as for the service tool v3400 on a printer of the PGI-x25/CLI-26 generation, so see this instruction.įeel free to ask if you have more questions about service mode operations for the MG6450. See a discussion about this in this lengthy thread.
Notice that the downloaded tool contains malware according to some antivirus programs and Virustotal. You find a download of the service tool v 4720 here. you need to disconnect the printer from the mains and wait for maybe a minute before turning the printer on again. A locked service mode shows a constantly lit error light when trying to enter service mode and the printer will be totally unresponsive. The use of an older service tool like v3400 will cause lock of service mode. Your MG6450 is the same cartridge generation, so I am sure the procedure will work.įor service mode operations you will need a service tool like v 4720 or newer. I have tested it with iP7250, MG5450 and MG5550 all are the PGI-x50/CLI-551 cartridge generation. This procedure works for printers of the PGI-x25/CLI-x25 and PGI-x50/CLI-551 cartridge generations.
