If your Canon TS9150 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

Ink absorber pads store waste ink during normal operation. Canon firmware tracks this using a software counter and may stop printing when it reaches the limit.

This page is prepared for Canon TS9150. Service mode instructions are shown only when a matching series procedure is known.

How to Enter Service Mode on Canon TS9150

Some Canon series require entering service mode before the ink absorber counter can be 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

After service mode is enabled (if required), the waste ink counter can be reset using a supported reset procedure/software.

Important Notes

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