About Canon Servie Tool V5610

– Canon Service Tool V5610 is a tool used to perform maintenance on Canon printers and reset Canon printers after replacement of parts such as replacing ink absorbents, print heads, printer mainboard, and others. Based on the many cases we have encountered, the Service Tool is most often used to reset ink absorber counter value when the waste ink absorber is full.
– The ink absorber is going to be full of box, it has to be replaced or cleaned the waste ink absorber. Also, replaceing or cleaning the waste ink absorber, you need to repair or reset the waste ink counter value, cause those parts are concerned to each others.
– So using Canon Service Tool V5610 to reset the waste ink counter value becomes effective when the ink absorber is replaced or cleaned.

– Canon Service Tool V5610 can use to fix error code 5B00, 5B02, 5B04, 5B14, 1701, 1702, 1700 on your printer. You must enter Service Mode on your printer to use this Canon Service Tool.
– If the printer can not enter Service Mode, you can not reset it by Canon ST V5610. In this case, change EEPROM on the logic board.
