Canon MG6840 Ink Absorber Full Reset

Canon MG6840 can lock printing when the waste ink (ink absorber) counter hits a predefined threshold. This guide explains how to reset it.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MG6840 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MG6840. Service mode instructions are shown only when a matching series procedure is known.

Common Symptoms

  • 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 MG6840

If your Canon MG6840 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 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.

Perform the Waste Ink Counter Reset

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

Maintenance Reminder

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