If your Canon MB2390 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 MB2390. 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

Clear the Ink Absorber / Waste Ink Counter

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

Maintenance Reminder

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

Reset tools and instructions

For best results, avoid rushing button presses—consistent timing matters.
