How to Fix Canon Support Code 6000

Canon Support Code 6000 indicates a Line Feed (LF) error. The printer cannot rotate the feed rollers correctly, usually because of a physical jam in the paper path or a dirty sensor film.

Step 1: Remove Paper Fragments

Even a tiny torn corner of paper wrapped around a roller will trigger a 6000 error.

1. Turn off the printer and unplug it.
2. Open the main cover and the rear tray.
3. Shine a flashlight down into the feed mechanism.
4. If you see any paper, gently pull it out.
5. Open the rear duplexer panel (if your printer has one) and check the secondary rollers.

Step 2: Clean the Line Feed Sensor (LF Film)

The printer tracks roller rotation using a clear plastic disc or strip with tiny microscopic lines printed on it. If this gets smeared with ink or grease, the sensor cannot read the rotation speed, triggering error 6000.

1. Ensure the printer is unplugged.
2. Open the main cover. Look to the far left side of the carriage area (next to the gears).
3. Locate the clear, circular plastic disc or a vertical clear strip (depending on model).
4. Use a cotton swab lightly dampened with window cleaner or isopropyl alcohol.
5. Very gently wipe the clear plastic. Rotate the feed rollers manually (if possible) to clean the entire disc.
6. Let it dry completely.

Step 3: Check the Output Tray Mechanism

Some models trigger a 6000 error if the motorized output tray fails to open.

1. Ensure there are no physical obstructions blocking the front output tray from dropping.
2. Gently pull the tray out manually if it seems stuck.
3. Plug the printer back in and power it on.
