Canon MB5390 Ink Absorber Full Reset

The “Ink Absorber Full” / service required message on Canon MB5390 is common after many cleaning cycles. In most cases, a counter reset restores printing.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MB5390 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MB5390. 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

Perform the Waste Ink Counter Reset

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.

Reset tools and instructions

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

Troubleshooting

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