Canon Pixma Printer F02 Error Code Fix (P02 Carriage Jam)

by

What This Error Means

On most Canon Pixma printers, what looks like F02 on the little display is actually P02. Same thing for you: it means Carriage Error. The print head carriage (the block that holds the ink tanks) can’t move smoothly along its rail, or the sensor that tracks it can’t read correctly. The printer stops to avoid slamming the head around and chewing up itself.

Official Fix

Canon’s official script is: power-cycle it, clear jams, then send it to service if the code won’t die. Do this:
  • Kill the power
    • Press the power button to turn the printer off.
    • Unplug the power cord from the wall for at least 60 seconds.
  • Check for obvious blockages
    • Plug the printer back in and turn it on.
    • If the carriage tries to move, let it stop, then open the top cover.
    • Look for jammed paper, labels, or packing material around the carriage path and paper feed.
    • Remove any paper you see in one piece if possible. Pull along the paper path, not sideways.
  • Inspect the paper path properly
    • Check the rear tray (if your model has one), the front cassette, and the output slot.
    • Remove any curled, folded, or torn scraps of paper.
  • Reset the printer
    • Close all covers firmly until they click.
    • Power the printer off again, wait 10 seconds, then power it back on.
    • Try a test print or nozzle check from the printer’s menu or driver.
  • If F02/P02 stays on
    • Canon’s manual answer: the transport system or sensors could be faulty, so the unit needs service.
    • At this point their official line is “contact your Canon service center”.

The Technician’s Trick

Here’s what real bench techs do that the manual never spells out. This is the stuff that actually clears most P02/F02 calls. Do this with the power unplugged.
  • Free the carriage by hand
    • Unplug the printer from the wall.
    • Open the top cover.
    • Gently try to slide the carriage left and right.
    • If it’s stuck, look hard for wadded paper, label backing, a pen cap, or dried ink blobs on the rail in its way and remove them.
    • Don’t force it; find what’s blocking it.
  • Clean the encoder strip (the real troublemaker)
    • Behind the carriage there’s a thin clear plastic strip running the width of the printer. That’s the encoder strip.
    • If it’s covered in ink mist or fingerprints, the sensor can’t read it and you get P02/F02.
    • Use a clean, soft, lint‑free cloth, barely damp with water. No alcohol, no window cleaner.
    • Pinch the strip gently between the cloth and slide along its length. Don’t yank, twist, or pop it out of its slots.
    • Let it dry for a minute; it should look clean and evenly clear.
  • Clean and lube the carriage rail
    • The metal rod the carriage slides on can get gummed up with old ink and cheap grease.
    • Wipe the rail with a cloth until you don’t see black/brown streaks coming off.
    • Put a tiny bit of light silicone or white lithium grease on the rail. Thin smear only; blobs cause jams.
    • Slide the carriage end to end by hand; it should move smooth, no grinding, no sticky spots.
  • Check the carriage belt and wiring
    • Look at the toothed belt that pulls the carriage. If it’s frayed, missing teeth, or hanging loose, that’s your problem.
    • Check the flat flex cable going into the carriage for kinks, tears, or that “half‑plugged” look. Reseat gently if it’s crooked.
  • Power test
    • Close the cover, plug the printer back in, and turn it on.
    • Listen: the carriage should glide smoothly side to side once, then park. If it slams, chatters, or stops short and throws F02/P02 again, the carriage motor or main board may be dying.
If cleaning the encoder strip and freeing the carriage doesn’t clear it, most techs either swap the whole carriage/rail assembly from a donor machine or tell you it’s not worth the bench time on a cheap Pixma.

Is It Worth Fixing? (The Financial Verdict)

  • ✅ Fix: Printer is under ~5 years old, was working fine before a bad paper jam, and F02/P02 appeared right after. Cleaning the encoder strip and freeing the carriage usually revives it with zero parts cost.
  • ⚠️ Debatable: Printer is 5–8 years old, heavy home/office use, and you suspect you’ll need a new carriage belt, motor, or encoder strip. Paying for parts plus labor gets close to the price of a new basic Pixma.
  • ❌ Replace: Printer is old, already has print quality issues (missing colors, banding), and F02/P02 comes back even after a good clean. If a shop quotes you for motor or mainboard replacement, put that money toward a new machine instead.

Parts You Might Need

  • Encoder strip – if the existing strip is scratched, stained you can’t clean, or physically damaged. Find Encoder strip on Amazon
  • Carriage motor (CR motor) – when the carriage twitches, buzzes, or won’t move even after it’s mechanically free. Find Carriage motor on Amazon
  • Print head / carriage assembly – for units where the carriage is cracked or the head has physically jammed and won’t sit square. Find Print head on Amazon
  • Silicone or white lithium grease – to relube the carriage rail after cleaning off old, sticky grease and ink. Find Silicone grease on Amazon
