When Canon TR5050 triggers an ink absorber full condition, the printer may block printing as a protective measure. The solution is typically a waste ink counter reset.

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 TR5050. Service mode instructions are shown only when a matching series procedure is known.

Typical Signs

• Service / maintenance warning on the screen or driver
• Printer refuses to print even with ink available
• Blinking lights and queued jobs fail
• Error reappears after restart

How to Enter Service Mode on Canon TR5050

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.

Finalize the Reset and Restore Printing

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

Important Notes

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

If your model does not show a service mode section, it means no matching procedure was found for its series.
