The “Ink Absorber Full” / service required message on Canon MP545 is common after many cleaning cycles. In most cases, a counter reset restores printing.

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 MP545. Service mode instructions are shown only when a matching series procedure is known.

How the Error Appears

• 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

Finalize the Reset and Restore Printing

After service mode is enabled (if required), the waste ink counter can be reset using a supported reset procedure/software.

Before You Continue

Resetting the counter does not physically clean the absorber pads. For heavy usage, pads may eventually need cleaning or replacement.

Reset tools and instructions

Use a reliable USB connection and follow the steps in order.

Troubleshooting

• Try a different USB cable/port if using PC software.
• Close other Canon printer utilities while resetting.
• Repeat the service mode steps carefully (timing matters).
• Use the correct Stop/Reset press count for your series.
• Power-cycle the printer and try again.
