Canon MB5420 Ink Absorber Full Reset

If your Canon MB5420 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

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 MB5420. 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

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.

Before You Continue

Treat the reset as a maintenance step. If your printer has extremely high usage, consider cleaning/replacing absorber pads to avoid overflow.

Download & get started

If your model does not show a service mode section, it means no matching procedure was found for its series.

If It Doesn’t Work

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