Canon error E04 and E05 (FINE cartridge not recognised)

E04 and E05 on the LED display mean a FINE cartridge is not recognised or is not installed correctly. E04 is shown when the cartridge cannot be identified; E05 is shown when the cartridge is the wrong type for this printer or when the printer cannot read it at all. They correspond to support codes 1682 and 1684 on models with screens.

What causes it

  • Cartridge not pushed up until it clicked into the holder
  • Protective tape still on the contacts
  • Ink or dirt on the gold contacts
  • Wrong cartridge model for the printer
  • Cartridge electronics damaged, often after refilling

How to fix it, in order

Work down the list and stop when the printer recovers. The steps are ordered from most likely and least invasive to last resort.

  1. Open the cover and find the flagged cartridge

    The ink lamp next to the display blinks; the number of flashes or the lamp colour tells you whether it is the black or colour cartridge. Lower the lock lever on that side.

  2. Remove tape and clean contacts

    Take the cartridge out, peel away any orange tape, and wipe the gold contacts with a dry lint-free cloth.

  3. Reinstall firmly

    Insert the cartridge at an angle, push it up and back until it clicks, then raise the lock lever until it clicks. Close the cover and wait.

  4. Check the cartridge number

    Compare the cartridge with the numbers printed inside the cover (for example PG-245 and CL-246, or PG-275 and CL-276). A cartridge from another series gives E05.

  5. Test with another cartridge

    If the error remains, try a different cartridge of the correct type. If the error follows the cartridge, it is faulty; if it stays with the slot, the holder contacts are the problem.

  6. Clean the holder contacts

    Unplug the printer and wipe the spring contacts inside the holder with a dry cotton swab, then reinstall and restart.

Stopping it happening again

When it is not worth fixing yourself

If you would rather not work through this alone, a printer specialist can take a look with you on a screen-share and tell you honestly whether the machine is worth saving.

Frequently asked questions

What is the difference between E04 and E05?

E04 means the cartridge cannot be recognised, usually a contact or seating issue. E05 means the cartridge is the wrong type or cannot be read at all. Check the cartridge number for E05.

Can I use PG-245 in a TS3300 that shows E05?

No. The TS3300 uses PG-275 and CL-276. PG-245 is for the MG2500 and MG3000 families.

Why does a refilled cartridge give E04?

Ink on the contacts or damage to the circuit during refilling. Clean and dry the contacts; if that fails the cartridge is done.
