Canon Pixma MP800: Troubleshooting Guide

Canon designed the PIXMA MP800 as an all-in-one printer, copier and scanner. It appeals to the home user who needs these office services but is limited for desk space. Even the best Canon printer can stop working. Troubleshoot your PIXMA MP800 to help find and fix common underlying problems that may affect the printer's performance.

Make sure the MP800 is plugged into a reliable power source--for the best results, plug it directly into an outlet instead of using an extension cable--and powered on if its front display panel is dark.

Check the front and back paper feeder slots if the MP800 makes strange noises or stops printing halfway through a printing job. The device may be clogged. Remove any pieces of paper that may be stuck.

Review the front LCD display screen for an error. The error message typically describes what's wrong and how to fix it.

Adjust the MP800's print head if your printer results look crooked or off-balance. Press the "On/Off" button to turn off the device, then turn it back on. Insert two A4-sized (letter size) sheets of plain paper into the MP800's top feeder slot. Press "Maintenance" on the MP800's display screen and use the arrow keys to scroll down to "Manual Head Align." Push "OK" and follow the on-screen prompts to complete the alignment process.

Clean the MP800's scanner bed if the LCD screen displays an error saying, "Cannot Obtain Clean Scan" or if your scanning results look streaked, splotched or obscured by debris. Canon recommends wiping the glass with a clean, lint-free cloth. Solid debris deposits can be removed with water. Don't use glass cleaners, as this may damage the MP800.
