If your Canon G4500 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

Inside Canon printers, absorber pads collect excess ink from cleaning and maintenance cycles. The printer uses an internal counter to estimate pad saturation.

This page is prepared for Canon G4500. Service mode instructions are shown only when a matching series procedure is known.

How to Enter Service Mode on Canon G4500

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.

Reset the Ink Absorber 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.

Reset tools and instructions

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

Common Fixes

• Power-cycle the printer and try again.
• Repeat the service mode steps carefully (timing matters).
• Try a different USB cable/port if using PC software.
• Close other Canon printer utilities while resetting.
• Use the correct Stop/Reset press count for your series.
