Canon TR4540 Ink Absorber Full Reset

If your Canon TR4540 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

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 TR4540. Service mode instructions are shown only when a matching series procedure is known.

How the Error Appears

• ‘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 TR4540

If your Canon TR4540 supports service mode reset, follow the steps below before performing the counter reset.

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

Completing the reset clears the internal ink absorber counter stored in printer memory and restores normal operation.

Before You Continue

Resetting the counter does not physically clean the absorber pads. For heavy usage, pads may eventually need cleaning or replacement.
