Keep a rarely used printer healthy

Inkjets clog when they sit idle. A few habits keep a once-a-month printer working.

01 · Identify — does this match what you see?

  • Prints fine, then nothing works after a holiday
  • Colours missing after weeks unused

02 · Resolve — follow in order

  1. 1

    Print one small colour page every week or two, even if you do not need it.

  2. 2

    Always switch off with the printer's own power button so the head parks and caps itself.

  3. 3

    Leave the printer plugged in — it runs tiny maintenance cycles on its own.

  4. 4

    Keep it out of direct sun and away from heaters; heat dries ink in the nozzles.

  5. 5

    Before a long trip, run a nozzle check so you leave it in a known-good state.

Pro tip

Pulling the plug at the wall is the single most common cause of clogged Canon printheads.
