  1. Turn on the printer.
  2. Open the front cover so the cartridges move to the center.
  3. Press and hold the Stop/Reset button (triangle inside a circle) for 5–10 seconds until the message clears.
  4. Close the cover.
  5. Try printing again — the warning may reappear, but you can repeat the step.

4. Important Warnings

  • Service Tool risk: Using third-party reset software can void warranty. Download only from trusted sources (virus risk).
  • Absorber pad: Resetting counter without changing pads will eventually cause ink leakage onto your desk.
  • Ink level reset: Canon deliberately prevents user reset of ink chips to enforce cartridge purchases.

Why Do You Need to Reset the Canon MG2540S?

Before clicking buttons, you must understand why your printer is demanding a reset. There are two distinct types of resets for this model:

  1. The Ink Level Reset (Tricking the Cartridge): The MG2540S uses PG-745 and CL-746 cartridges. The printer stops printing when it thinks the ink is empty, even if you just refilled it. This requires a cartridge reset.
  2. The Waste Ink Pad Reset (Service Tool): Inside your printer is a sponge that catches excess ink during cleaning cycles. Once Canon’s counter hits 100%, the printer locks down permanently until you reset the counter. You will see Error 5B00 or E08.
