Canon iP8780 Ink Absorber Full Reset

If your Canon iP8780 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

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 iP8780. Service mode instructions are shown only when a matching series procedure is known.

What You May Notice

• ‘Ink Absorber Full’ / ‘Service Required’ message
• Support/service code (varies by series)
• Printing blocked after cleaning cycles
• Reset required to continue printing

Finalize the Reset and Restore Printing

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

Maintenance Reminder

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