During head cleaning, surplus ink is routed to internal absorber pads. Canon TR5090 monitors this via a counter and can lock printing at a threshold.

How to Enter Service Mode on Canon TR5090

To access maintenance functions, Canon TR5090 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.

Perform the Waste Ink Counter Reset

Once the counter is cleared, Canon TR5090 should exit the locked state and printing should resume normally.

Before You Continue

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