Yes that it 's the most possibillity.
but you must be assure that :
- the paper is not moist. (it makes pale copies)
- the glass has you cleaned up. (it makes black background uneven)
- the transfer unit is not dirty. (it makes black background)

How do I prevent excess toner from spilling out of cartridge and affecting copies?


If you 'replaced' or refitted the original cartridge, then I would suggest that the toner cartridge has failed. If this is the case, please try a new one.
If the original has not done a fair (check manufacturers specification) number of prints, you may be able to ask for a replacement.
If this was a new cartridge, and printer uses separate drums and toner cartridges. Then it could be a faulty drum. Above replacement path could be tried.

A toner catridge leaked in my Canon PC921. I cleaned it up and installed a new cartridge, but now my copies are dark on one side, light on the other.


Hello,
on analogue copiers, if You have dark copies, that means that You need to clean optics ( mirrors and lenses - maybe some toner get to them ) or check/clean/replace the fixing film!

Regarding poor copy, clean/vacume/change the transfer roller ( beneath the drum unit - on paper path from drawer/bypass, before fixing unit ).

Hope that helps!

Canon FC120 mono copier. First few copies are ok, then they get blured and out of focus? Any suggestions? Cheers


This sounds like a problem with the laser. Have you replaced the toner setup recently? Could be a bad cartridge. This model uses an all-in-one toner/drum.

If the toner cartridge is not the problem, try cleaning the laser bar (usually clear plastic about 2.5mm wide). There are two other possibilities (at least) but requires dis-assembly and electronic repair knowledge. There could be a mechanical problem with the optical copy assembly. This is unlikely due to the fact that the first few copies are OK. The other repairable problem could be power supply. Defective components (especially capacitors) can cause low power and may be affecting the power of the laser causing it to be out of focus.

I scored a laser printer with duplex because a couple of capacitors were bad.

I have a Canon Imagerunner 1310 and I am getting a message that my waste tomer is full and that I need to prepare a new drum. What does this mean? Can I do it on my own? Will I need to buy something?


Most of the time, if your copies are good, all you have to do is dump the waste toner from the drum. Slide the top to the left and raise the blue cover on the right. Lift the drum and developer unit out of the copier. At the top of the drum you will see a quarter size white plug that should be removed and gently turned over and gently shaken over a trash can to empty the drum. It doesn't have to be emptied completely. If your copies are bad then the drum has to be replaced. Not that hard for the lay person. Lift blue clips and the drum separates from the developer assembly. There was a Canon modification to use two small screws to keep the drum and developer together should the blue clips move out of position. These may have to be removed and put back. Raise the drum guard to make reassembly easier.

My copies have streaks of black on them. Do I need to replace the toner?


Maybe, what kind of Canon is it? You may have a cartridge with the toner & the drum? Or you may need to have the drum unit replaced O the drum & cleaning blade replaced or you need to clean the adf slip glass

GRAY STRIPES ON COPIES FROM CANON IMAGERUNNER 210S


Have you replaced the drum unit resently? When you had the drum unit out did you see the lines on the drum it self? If so, you need a new drum... If you did not see lines on it the problem may be coming from the fixing film, most of the time if the film is bad you can rub the toner off the page... Good Luck...

Error Message Drum Life Over, Replace Drum


The "drum" referred to is the imaging drum which is replaced separately from the toner cartridge. The drum life is rated for a certain number of copies, and the printer is telling you it's time. Replacement drums are available at big-box office places and from many online sources. Just do a Google search for "kx-fl511 drum". The new drum just slides in much like the toner cartridge, so replacing it isn't difficult.

Canon PC921 copier has blurry section on copy


what you probably brushed over was the transfer roller(black and spongy?). first try running 20 or 30 blank copies through the machine. If that doesnt work take a dry paper towel and gently wipe and rotate that black roller. that should take care of the problem. If the roller needs replaced you should have a technician do it. You could break the machine beyond repair.

Sounds like your drum cartridge might be bad.
Something you can try that might narrow down the problem is to make a copy of something and shut the copier OFF in mid copy.
(Basically, when the light is about 1/2 way finished scanning.)
Then, open the machine up and removed the jammed paper which should be 1/2 way through your machine and hopefully about 1/2 way under the drum/toner cartridge unit.

See how the copy looks at that point. **** FYI **** The toner on the paper is NOT FUSED so it will RUB OFF. Keep the paper away from your clothes and toss it.
IF your copy has smudges on it, then there is a real good chance that your drum unit is bad and needs to replaced.

If the copy looks good, then there is a possibility that the fuser unit is bad and needs to be repaired.

I would say that your drum unit is bad with my experience with Canon Copier.

If you still have more questions, feel free to ask.
Have a good day.
Good luck.
