If your Canon MG5720 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MG5720 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MG5720. Service mode instructions are shown only when a matching series procedure is known.

How to Enter Service Mode on Canon MG5720

To access maintenance functions, Canon MG5720 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 6 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 MG5720 should exit the locked state and printing should resume normally.

Maintenance Reminder

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