: For printers equipped with an ink absorber (a component designed to absorb excess ink during cleaning cycles), the tool can reset the ink absorber counter. This is particularly useful when the printer indicates that the ink absorber is full, even if it has been cleaned or replaced.

Use Genuine Software: Be wary of "cracked" versions that may contain malware or brick your printer firmware.

: The Canon Service Tool V3800 is primarily intended for use by authorized Canon service technicians. Its use requires a good understanding of printer mechanisms and electronics.
