What is Error 6000 (P03) on a Canon Printer?

Error 6000 (P03) happens when your Canon printer can’t properly feed paper due to an obstruction, sensor issue, or internal malfunction. Instead of printing, your printer flashes warning lights or displays an error message on the screen.

Why Does This Error Occur?

Several things can trigger Canon Error 6000 (P03):

• Dust, debris, or foreign objects (like a paperclip or pen) stuck in the feed tray

• The paper tray is overloaded or misaligned

2. Faulty or Dirty Encoder Strip

• This confuses the printer’s sensors, causing the error

3. Ink Cartridge or Printhead Issues

• Ink cartridges are not installed properly

4. Internal Hardware or Software Glitch

• Printer settings got corrupted

• Internal hardware issue (rare, but possible)

Now that we know the possible causes, let’s fix the error step by step!

Steps to remove paper jam

If your Canon printer has a paper jam, follow these simple steps to safely clear the paper and avoid causing any further damage.

How to Resolve Canon Printer Error Code 6000 (P03) – Step by Step

Step 1: Restart Your Printer (Quick Reset)

1. Turn off the printer.

2. Wait 5 minutes to allow the printer to reset.

3. Plug it back in and turn it on.

🔹 Why? Sometimes, a simple reset clears minor system glitches!

Step 2: Check for Paper Jams & Obstructions

1. Open the printer cover and carefully remove any jammed paper.

2. Check inside the paper feed tray for tiny paper scraps, dust, or objects.

3. If the tray is overloaded, remove some sheets and reload properly.

🔹 Tip: Always use clean, dry, and correctly sized paper to prevent future jams!

Step 3: Clean the Encoder Strip (Fix Sensor Errors)

1. Open the printer’s front cover and locate the thin plastic strip behind the printhead.

2. Gently clean it with a lint-free cloth and some isopropyl alcohol (avoid touching it with bare hands).

3. Let it dry, then close the printer and restart.

🔹 Why? A dirty encoder strip confuses the printer’s sensors, triggering errors.

Step 4: Reset the Printer to Factory Settings

1. Press and hold the Stop/Reset button for 5-10 seconds.

2. Release when the power light starts flashing.

3. Allow the printer to restart.

🔹 This removes any corrupted settings that might be causing the issue.

Parts to Replace to Fix Canon Printer Error 6000 (P03)

If troubleshooting doesn’t resolve Error 6000 (P03), some hardware components may need replacement. Here are the key parts to check:

1️⃣ Paper Feed Roller – If the roller is worn out or damaged, it won’t pull paper correctly, causing jams. Replacing it can restore smooth paper feeding.

2️⃣ Encoder Strip – A dirty or damaged encoder strip can cause misalignment errors. If cleaning doesn’t work, replacing it may be necessary.

3️⃣ Paper Sensor – A faulty paper sensor may mistakenly detect a paper jam even when there isn’t one. Replacing it can clear persistent error messages.

4️⃣ Paper Feed Motor – Look carefully at the gear of the printer to see if it is moving a little. If it is not moving at all, then it is possible that the paper feed motor is not working.

5️⃣ Printer Gears & Feed Assembly – If internal gears are broken or jammed, the paper won’t move properly. A technician may need to replace or realign them.

📌 Tip: Before replacing any parts, try cleaning and resetting the printer. If the error persists, contact Me for help. 😊
