Copier is Canon PC 720 Copier turns on, but makes

Copier is Canon PC 720 Copier turns on, but makes a grinding sound. Nothing else works: Print button, number of copies button, zoom, magnify or minimize size, dark/light control. Error message of E2 flashes. There is no paper jam. We have checked the belts, We have unplugged it and replugged it in. No change. It printed one copy that was very blurred before it quit. It made the same sound it is still making now. We let it sit a few days. We tried it again, and it successfully printed one copy, so we thought it was fine, and ran 10 copies of same item. When we put the next item in to copy, it turned on and then nothing else worked, as explained above.

You said you unplugged your copier, did you unplug it for 10 to 15 minutes before plugging it back in, plug it into a differed
outlet that you know works and plug it directly into a wall outlet instead of a power strip. Check to see if your copier reaches stand-by mode then make a test sheet.

If this does not work then you have probably have an internal processing component which requires attention.

This is Canon PC310 personal copier. When it starts, it's making some noise sounding like paper grinding a bit, and orange light blink for about 5 seconds, and power itself is down. So it does nothing now....

Hello sunny,
I'm not being rude or critical, but with the limited information I've been given I can merely give a "best guess". The "rustling of paper" sound or "grinding of paper" sound is probably the fixing assembly. The fixing assembly uses heat and pressure to bond the toner to the paper. Without going into more details than necessary the fixing assembly can both make that sound AND because of the extreme temperature it uses, any malfunction will cause the copier to turn off for your safety. Fire is not good ! I just made a quick surf across the web. You did not pay as much for the copier as it will cost to have it fixed. You bought a GOOD personal copier from a GOOD company. But all things have a lifespan. I'm just giving you my honest opinion. And I could be wrong.It won't be the first time somone spent 23 years in a career and still was a fool. I wish you well. SPINAL

make sure cartridge is fully installed and sitting properly. Sounds like gears are not meshing so check gears with cartridge out (bottom of copier) and see if they are damaged. If so, copier is junk.It might not be out of toner just can't read it properly as it is not seated proper.

Canon mf6530 crumples paper and makes grinding noise when trying to print.

I pressume that paper is wrinkled in fixing section. Probably the fixing bushings are worn out. The grinding noise could be from paper when it stuckes, but also from gears.Call service.
There is a trick if paper is moisturized. Flip paper in cass. up side down, and try again.

Shows paper Jam on Canon 720 PC photo copier

Sounds funny but this model shows a jam when the exposure lite goes bad. Turn on the copier and watch the exposure lamp, should lite up and not flicker. Lamp is still available.

Check if you have any matter that is blocking the paper path, also try to clean the rollers that picks up paper. If you happened that copier is in a dusty enviroment, dust could deposit on rollers, and rollers when picking up paper will start slipping. Try to clean with alcohol.
