Canon TS9541C Ink Absorber Full Reset

When Canon TS9541C 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 TS9541C. Service mode instructions are shown only when a matching series procedure is known.

How the Error Appears

• 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 TS9541C

If your Canon TS9541C 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.

Finalize the Reset and Restore Printing

Once the counter is cleared, Canon TS9541C 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.
