Resetter Tool Extra Quality - Canon Service

The Canon Service Tool is an official maintenance utility used by technicians to perform deep system resets, most notably to clear the 5B00 error (Waste Ink Absorber Full). Because this tool can be destructive if used incorrectly, it is primarily distributed through official service channels. Essential Preparation

1. Remove the printer casing (usually 6–8 screws under labels).
2. Locate the rectangular sponge pad (usually on the right side at the bottom).
3. Remove the pad. Wear gloves—it will be saturated with sticky ink.
4. Rinse the pad under warm running water until the water runs clear. Squeeze it dry (do not twist—pat with towels).
5. If the pad is disintegrating, replace it with a piece of aquarium filter foam or felt.
6. Dry everything thoroughly before reassembling.
