Question about Canon ImageRUNNER 330s Copier

1 Answer

Dark Printouts I believe that the image drum may be causing the dark printouts, please confirm this and if possible supply a replacement part number? If there may be another part that causes the issue please do not hesitate to let me know. I already removed the charge wire, cleaned it along with refill of toner and vacumed all of the paper path areas and still have no results.

My printouts have a very dark haze over them.......the printed letter are fine but it looks like the print cartrige is dumping ink on my paper as it prints. It look like a bad fax copy. What is the...

Either you purchased a a bad quality remanufactured toner cartridge or your fuser film is damaged.

If there is some kind of debris in black color that is on printouts, your fuser film might be damaged. Have a printer technician replace it.

If there is no debris, only bad quality printouts, it's the toner cartridge that needs replacement.

A white piece of paper is printing out gray....think the toner is ok as the ink is black...something need to be cleaned?


Two things can cause this type of problem, 1 bad drum unit or 2 dirty corona wire.

HTML clipboard Below are the directions to clean the wire.
1. Open the front cover and pull out the drum unit and toner cartridge assembly.
2. Clean the primary corona wire inside the drum unit by gently sliding the blue tab from right to left several times.
3. Return the blue tab and click it into the Home position.
4. Reinstall the drum unit and toner cartridge assembly in the MFC/Printer.
5. Close the front cover.

Be sure to return the sliding blue tab back to the home position next to the arrow or you will have dark streaks on your printouts.

If this does not solve the problem then you will need to replace the transfer drum in the printer. The part number for the drum is DR-400 or DR400.

I hope this helps, if so please rate our solution.

The printer is printing dark vertical line on the

90% or more of the time on this printer dark lines are coming from your toner/drum cartridge. You can verify this by changing cartridges if you have a spare. If you don't then remove the cartridge and look at the colored cylinder in the cartridge and see if the same "lines" are on the cylinder that are on your prints. This will tell you for sure that the cartridge is bad.

Remove the toner cartridge and use a soft cloth to wipe the photo drum clean of toner. Put it back and try again, if you still get bad prints, then you need a new toner cartridge.

Ink gets carried over to subsequent sheets

More than likely your maintenance kit roller has been impacted with ink and is not applying enough lubricant to the drum. You can replace the maintenance kit and run cleaning procedures a couple of times to allow it to clean up.
Now the other issue is if you are using a third party ink stick. By that I mean non xerox brand ink sticks. I have seen those cause that problem more often than not.
Pull out the maintenance kit and see if the large roller, which should be a off white, is black.
Exacly what is happening is your maintenance kit puts a very thin film of silicon oil on the drum so that the ink does not adhere to the drum more than normal. When that roller becomes blackened, it isn't very effective and you get some of that residual imaging.
