The Canon PIXMA iP4200 is a colour inkjet printer that can print up to 29 pages per minute in black and white and up to 20 pages per minute in colour. If problems occur with the iP4200, troubleshooting steps should be performed to diagnose the possible cause of the issue. Most of the commonly occurring problems can be resolved by going through the troubleshooting process.
Check the USB cable connection if the printer is not responding to print commands. Make sure it is securely connected at the computer and the printer.
Check the ink tank lamp if printouts are missing colours or sections. Open the top cover. Make sure the ink tank lamp lights red. Replace the ink if the lamp is flashing red. A flashing red light means the ink tank is almost or completely empty.
Align the print head if straight lines are printing out misaligned. Load a sheet of letter-size plain white paper into the auto sheet feeder. Hold down the "Resume/Cancel" button until the power lamp flashes green four times. Release the button. The print head will automatically align.
Clean the print head if printouts have missing lines or if they have white stripes. Hold down the "Resume/Cancel" button until the power lamp flashes green once. Release the button. The print head cleaning process will run automatically.
Clean the paper feed rollers if the back of the printout is smudged. Remove any paper that is loaded into the printer. Press the "Paper Feed" switch on the printer. Hold down the "Resume/Cancel" button until the power lamp flashes green three times. Release the button. The paper feed roller rotates as it self-cleans. Repeat the cleaning process two more times. Load a stack of plain white paper into the auto sheet feeder. Hold down the "Resume/Cancel" button until the power lamp flashes green three times. Release the button. The paper will load through the printer and then it will be ejected.
Check the loaded paper for curls if printed surfaces come out of the printer scratched. If the paper is curled, turn it over or replace with flat paper.
Restart the computer if print jobs will not start. This clears the memory of things that may be interfering with the computer's ability to communicate with the printer.
Close the top cover if the printer stops during a print job. The printer may pause if the print head overheats. Leave the top cover closed for about 15 minutes to allow the print head to cool. Reopen the cop cover.
