Canon MP237 Service Required Error – Reset Solution

Canon MP237 Ink Absorber Full Reset

Canon MP237 can lock printing when the waste ink (ink absorber) counter hits a predefined threshold. This guide explains how to reset it.

Ink absorber pads store waste ink during normal operation. Canon firmware tracks this using a software counter and may stop printing when it reaches the limit.

This page is prepared for Canon MP237. Service mode instructions are shown only when a matching series procedure is known.

Common Symptoms

Service / maintenance warning on the screen or driver
Printer refuses to print even with ink available
Blinking lights and queued jobs fail
Error reappears after restart

Clear the Ink Absorber / Waste Ink Counter

Completing the reset clears the internal ink absorber counter stored in printer memory and restores normal operation.

Warnings

If absorber pads are truly saturated, ignoring maintenance can lead to ink leakage inside the printer. The counter reset only removes the software lock.
