The Canon Pixma MX700 multifunction printer includes an LCD screen that displays various error codes whenever a hardware or software problem occurs. Each error code is tied to a specific type of problem to make the troubleshooting process easier. Error code 5100 describes a physical problem, with either a paper jam or an ink tank being misplaced. Resolving the error is a quick process that only requires standard troubleshooting procedures.
1. Press and hold the “On / Off” button, located on the printer’s operator panel, for one second. Wait 15 seconds and then press the button again. Try to print or scan a document.
2. Check the paper feed tray at the front end of the Canon MX700 to see if there is any visible paper inside the printer. Open the printer cover by grasping the front edge of the printer and pulling up.
3. Grab the edge of the jammed paper and gently pull toward you to remove the paper from the paper feeder. Unplug the USB cable and the power cord from the Canon, and then rotate the printer around.
4. Pull out the rear cover tab and check for any visible paper jam. Grab the edge of the paper and gently pull it toward you until the paper is removed.
5. Push the rear cover tab into place, and reconnect the power cord and USB cable. Try printing or scanning another document to see if the error is resolved.
6. Lift open the printer cover again and wait for the ink carriage to slide into view. Press the “Push” button on the front of the first ink tank. Pull the tank out until it snaps into place to make sure it is properly seated.
7. Repeat the process for the other three ink tanks and close the printer cover. Turn off the printer and turn it on again.
Tips and Warnings
You will need to contact Canon customer service for a repair or replacement if the 5100 error code continues to flash on the LCD screen after going through the troubleshooting steps.
