The “Ink Absorber Full” / service required message on Canon TR8020 is common after many cleaning cycles. In most cases, a counter reset restores printing.

During head cleaning, surplus ink is routed to internal absorber pads. Canon TR8020 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon TR8020. Service mode instructions are shown only when a matching series procedure is known.

How to Enter Service Mode on Canon TR8020

If your Canon TR8020 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.

Reset the Ink Absorber Counter

Once the counter is cleared, Canon TR8020 should exit the locked state and printing should resume normally.

Before You Continue

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