Canon TR8000 Ink Absorber Full Reset

The “Ink Absorber Full” / service required message on Canon TR8000 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 TR8000. Service mode instructions are shown only when a matching series procedure is known.

How to Enter Service Mode on Canon TR8000

To access maintenance functions, Canon TR8000 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.

Finalize the Reset and Restore Printing

Once the counter is cleared, Canon TR8000 should exit the locked state and printing should resume normally.

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.
