I would use a soft toothbrush and a little Isopropyl Alcohol and then a lint free cloth and then give another gentle brush. There are some other ideas here. Take no notice of the answer by 'Marvin' on Fixya about dropping the head in boiling water, I think he thinks he is dealing with a colour inkjet printer.

Error P03 on a Canon printer typically indicates a paper jam, even if you cannot physically see any jammed paper. Here are a few steps you can try to resolve the issue:
Turn off the printer and unplug it from the power source.
Carefully check the paper tray and inside the printer for any jammed paper or debris.
Remove any jammed paper or debris you find.
Plug the printer back in and turn it on.
Attempt to print again.
If you don't see any paper jammed in the printer, there are a few other things you can try to resolve the error P03:
Try resetting the printer. To do this, turn off the printer, unplug it from the power source, and wait for a few minutes before plugging it back in and turning it on.
Check the ink cartridges and make sure they are properly seated and have enough ink.
Clean the printer's rollers. Rollers are the small rubber wheels inside the printer that move the paper through the printer. Over time, dust, debris, or ink can build up on the rollers and cause paper jams. Cleaning the rollers can help resolve the issue.
Try to update the firmware of the printer. Sometimes, a firmware update can resolve the issue.
Check the printer's settings, ensure that the size of paper loaded match the size of paper set in the settings.
If the problem persists after trying these steps, you may want to contact Canon support for further assistance.
The E732-001 error on a Canon iR 3225 indicates an issue with the fixing assembly temperature. Here are some steps to troubleshoot and resolve this error:
Reset the Condition:
Enter service mode by pressing the following sequence on the control panel: COPIER > FUNCTION > CLEAR > ERR.
This will reset the error condition. If the message disappears, your printer is ready to use. If this doesn't work, there may be a hardware problem as addressed below.
Replace the Main Thermistor:
The main thermistor is responsible for temperature sensing. If it's faulty, it can trigger the E732-001 error.
Consider replacing the main thermistor to resolve the issue.
Check the DC Controller PCB:
If the problem persists, inspect the DC controller PCB for any defects or malfunctions.
Replacing the DC controller PCB may be necessary.
Remember to turn off the printer before performing any maintenance tasks. If the error persists or if you need further assistance, I recommend contacting your local authorized Canon dealer or the Canon Customer Support Center for professional service
Question edited for clarity and add CAPS.
Is there a paper roll in it? I have seen them do this as the calculator is trying to feed the roll edge. You can turn printing off, but most need a roll in place. There is a repair video for a similar machine.
