Pages are printed with black and/or smeared prints on them

U didnt write what model of machine you hawe,but probably,I thinh the fixing roller or film on your's machine heater is damaged

Smeared output can result when you refeed a printed page into the printer to make a double-sided page. This happens because the rubber rollers that grip the paper to pull it into the printer can pick up toner from the first side’s printing and smear it. So before replacing parts, this is an easy thing to check. Printing multiple pages consecutively will make the pages print progressively cleaner or you can clean the rollers with rubbing alcohol.

Smeared toner also happens because the nonstick coating on the fusing roller is scratched or has baked-on debris. This can happen if the printer is in a dirty environment especially. If you are comfortable removing the fuser, you can try to clean it with a soft cloth and alcohol, but make sure you let it cool down first!

Finally, if this does not resolve your issue then make sure the fuser is heating; toner that is not heated properly will fall from the page and smear. If the thermostat is bad or the fuser not working properly, you will most likely need to replace the entire fuser assembly. This will be pretty expensive to repair so hopefully it's one of those other issues.

Have you looked at the roll in your maintenance kit? It may be dry in that area and not applying enough lubricant on the drum. Or you have some contaminant on the print head wiper blade or the mylar strip in the maintenance kit. Sounds like something is making contact with the drum causing your problem.

I was getting a similar blur/blob down one side of the paper (with no discernable print anywhere,) but after removing and emptying the toner collection bottle my printing returned to normal. I am still working on the size mismatch issue, which seems to be prevalent in the 2300DL population.

Your printer has ink build up inside it. This comes from cleaning cartridges and builds-up steadily over time. Remove top cover. Wet a cotton swab with isopropyl alcohol (available at drug stores) and clean the inside. use a cotton bud where the swab gets entangled.

We were having a lot of print quality problems, similar to what you describe. We replaced the drum and it worked fine.

Okay, this was the problem I posted a few days ago. It's fixed now, so in case you have the same problem with smearing, here's what the help desk from Canon suggested: Open the cover and remove the ink cartridges. There is a gray lever in front of the cartridges. Lift this lever and the printhead can be easily removed.
Our printhead had a buildup of black ink on the surface. I carefully removed this with rubbing alcohol. I let the printhead dry and replaced everything. No more smearing. Imagine a help-desk that actually helped!

This could be the Fuser Assembly. The Fuser is the unit that heats up and makes the toner ahere to the paper. The fact that it is smearing, means that the Fuser is not heating correctly. I would call for service on it.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

When you get the paper, can you smear the print with your fingers, or is printed on there properly.

if you can smear it, it would be your fuser not doing its job properly, if you cant, then its your replacement toner as it most likely incorporates the drum in it, which i think is your problem.

It sounds like you have a black ink leak and it is smearing onto the paper when you print. I don't know any reasons for this except if you topped the black ink up yourself, and didn't re-block the hole you made. Then I guess the ink would gravity drip onto the paper tray while you weren't printing. Otherwise I would suggest changing the print head, but this might be expensive.
