The “Ink Absorber Full” / service required message on Canon iP8740 is common after many cleaning cycles. In most cases, a counter reset restores printing.

Inside Canon printers, absorber pads collect excess ink from cleaning and maintenance cycles. The printer uses an internal counter to estimate pad saturation.

This page is prepared for Canon iP8740. 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

Reset the Ink Absorber Counter

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

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.
