Canon MB5390 can lock printing when the waste ink (ink absorber) counter hits a predefined threshold. This guide explains how to reset it.

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 MB5390. Service mode instructions are shown only when a matching series procedure is known.

Typical Signs

• ‘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.

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.
