The “Ink Absorber Full” / service required message on Canon TS5391 is common after many cleaning cycles. In most cases, a counter reset restores printing.

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 TS5391. 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

How to Enter Service Mode on Canon TS5391

To access maintenance functions, Canon TS5391 may need to be placed in service mode first.

1. Turn the printer OFF.
2. Press and hold Stop/Reset.
3. While holding Stop/Reset, press and hold Power.
4. Release Stop/Reset (keep holding Power).
5. Press Stop/Reset 5 times.
6. Release Power — the printer should enter service mode.

If it doesn’t work, repeat the sequence carefully. The press count depends on the series.

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.

Before You Continue

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