Before using the tool, you must put your printer into . If this is not done correctly, the Service Tool will not communicate with the printer. Step 1: Enter Service Mode (Crucial) Turn off the Canon MP250 (keep the power cord plugged in).
The Canon Service Tool is a piece of software with a specific and powerful function: to interface directly with a Canon printer's internal memory (EEPROM). It can reset internal counters and change operational parameters that standard software cannot access. Its primary use is to clear the printer's waste ink absorber counter. The waste ink pad, a sponge-like component inside the printer, collects excess ink from cleaning cycles. Once this counter reaches a limit, the printer locks up with an error (like 5B00) to prevent overflow. The service tool resets this counter, allowing the printer to function again.
