Do you mean blurry, like toner isn baked, or ... If yes, dispite the good conditions of fixing roller, you may want to replace bushings of fixing rollers too. Because they do not generate enough pressure.
Sounds like a bad power supply. The clicking is a solid state relay coming on, but it's either not putting out anything from there (ac 120v power supply) or the DC power supply is bad. Not a user fix...sorry! Call a qualified service tech anytime you are dealing with power issuses!
The paper feed system is worn (rollers, and separation pad). What is happening, is extra sheets are being fed into the machine primarily because the separation unit is not doing it's job properly. So rather than just one page at a time being fed, it is allowing an extra sheet to "creep" in intermittently, causing the jam. And the indicator you are seeing is the "jam" indicator.
Just fyi, a Canon PC-6e is a copier that is about ten + years old of a model... The drum unit will make the copies better.... But, you most likely need to clean the optic's. Have you tried to make the copies lighter??? If I am correct, there is a small botton on the control pannel that will turn... It will make the copies light one way and darker the other way... Good Luck
The machine optics are probably dirty and needs to be cleand. You can try to take out the drum unit and locate a small glass strip that sits above the drum in the frame of the machine. if you can find it, try to clean it and this should help some without taking the machine apart.
Troubleshoot this issue step by step:
Check the Feed Selection Lever:
Ensure that the Feed Selection Lever (located on the lower left side of the front of the scanner) is in the correct position (up) for separation.
Straighten the edges of the stack of documents to be scanned.
Set the document guides so they are wider than the document to be scanned.
Place the documents face up into the feed tray, ensuring they touch the document stoppers.
Clear Any Jammed Paper:
Be careful when removing jammed paper to avoid cuts.
Remove any documents that have been left in the eject tray.
Close the document eject tray.
If the document ejection is stopped partway, perform this operation with the document eject tray extension open.
Hold the upper unit as shown in the diagram and open it to the point where you can remove the jammed document. The pickup roller is located in the middle of the upper unit. Do not hold the protrusion on the upper unit when opening it, as it may deform the pickup roller or cause a feeding error.
Close the feeder cover.
If the jam occurred in the feed section, pull the document out carefully without applying too much force. Be sure to remove any torn parts remaining in the scanner.
Close the upper unit slowly, ensuring it clicks into place. Do not force it to close, as this may damage the scanner.
After removing the jammed paper, check if the last page was scanned, and then continue scanning.
Rapid Recover System:
If a paper jam occurs when the "Rapid Recover System" is enabled in the ISIS/TWAIN driver settings, the image of the document is not saved, and scanning stops. You can continue scanning from the document that caused the paper jam after fixing the issue.
Additional Considerations:
Make sure the pickup rollers retract when the machine is powered on.
Check that the stopper plates are in the down position.
Verify that the upper unit is completely closed after clearing the jam.
Remember to handle the scanner components carefully to avoid damage. If the issue persists, consider seeking professional assistance or contacting Canon support for further guidance
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.

You mentioned that you have already replaced the Laser Unit, but the error persists. Here are a few more steps you can try:
Check the cable: Ensure that the cable connected to the Laser Scanner Unit is properly attached and not damaged.
Replace the DC Controller PCB (PCB4): If the error still persists after checking the cable and replacing the Laser Scanner Unit, you might need to replace the DC Controller PCB (PCB4)

If your Canon iPF605 printer won't enter service mode and gets stuck at the "S" symbol without initializing, it may indicate a firmware or hardware issue. Consider updating the firmware or contacting 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
