I took it apart the way you are supose to and fixed it, did you guys think that I was going to wait around till you guys came around. Thanks anyways but I am a technician and have been or the last 11 years and thanks for trying to sell me something that is already free on the net. The only thing is that I rarely work on Canons so that is why I was asking for some assistance, but it is the same as any small Kyoceras, Minoltas, Sharps, Xerox, Brothers, etc. Thanks again though.

There is a clicking type noise when I print and on the right side of my pages the ink is smudged so much that you can't tell there were words, just a bunch of smeared ink.


Try changing the toner cartridge. If you have a spare toner swap it out. If you have to order a toner, and it ends up not being the problem, you can still store the toner out of light in a normal room temperature until the original toner is empty.

If it isn't the toner, the next option is the fusing assembly. This is in the back of the printer and gets warm/hot to melt and bond the toner on the paper. It usually isn't a user replaceable part. There is a film on the fuser roller that sometimes gets worn or broken especially if there has been a bad paper jam removed incorrectly. If you see little pieces of grey/brown plastic like or teflon coated things in there, its probably the fuser.

If the printer is under warranty you can call HP for service, if not, you can find a local service person to fix that. Shouldn't be too expensive for a fuser. Cheaper than a new printer.

The ink is smearing on to the copy. The text keeps on reappearing on the page.


It sounds like either your drum needs to be replaced (needs to be done every 5 or 6 toner cartridges), or you have a bad fuser (depends on what you mean by smearing).

When an image reappears further down the page (not as dark or bold) it usually means that the current in the drum is not correct, or the coating on the drum is worn. Take the cartridge assembly out and separate the drum from the cartridge. DO NOT TOUCH THE DRUM ROLLER. Look at it and see if there are streaks, color differences, or toner on the drum roller. The roller should be solid purple or green with no marks, lines, toner, or smudges on it. If it does, the drum is a replaceable part and you can get one anywhere that sells toner cartridges. They are even available in remanufactured brands.

However, if there is loose toner on the paper (wipe your hand over it and it comes off), then your fuser is bad and needs to be replaced. Another problem with the fuser you can check is whether there is toner being adhered to the fuser rollers, which could cause smearing and images to reappear on the page. To check this, open the rear cover of the printer. Inside you will see two rollers: usually an orange one on top of a black one. Be careful; the fuser can heat up to almost 400 degrees, so let it cool if you were just using it. Check to see if there is any toner on these rollers; if working properly, they should be spotless. If there is toner visible on either roller, then you may need to replace the fuser.

It is a 75% chance of your drum being the cause, which would be the problem to hope for. If your fuser is bad, in all honesty it may not be worth fixing; it can cost you up to $150.

I hope this helps! Good luck!

I can not get my copier to work at all it just leaves a j 3 message. When it was working black lines were being left over every copy page


where the black line being left when after the drum or before the fuser THe hot part. make a copy and stop the machine so the paper is in the middle catch it before it goes into the hot part are the lines there? be careful the toner will not be fuse your hand will smear the toner, if the lines are there you need to replace the cleaning blade and maybe the drum and get the image unit that houses the drum might need to be cleaned.

if no lines then the fuser is putting the lines on the copy replace the upper and lower fuser rollers and cleaning roller next to the lower fuser roller.

RICOH 1224C COPIES ARE SMEARED


Smeared output can also 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 this is an easy thing to check. Printing multiple pages consecutively will make the pages print progressively cleaner.

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!

If this does not resolve your issue then make sure the fuser is heating; if not, the thermostat is bad and 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.

When documents print out, one side of the copy is smeared. We cleared out a paper jam and I think part of the lining of the roller came off.

As for the noise, there are several complex gear and roller segments that drive the paper between the paper tray, the scanner, the fuser, and the finisher. If these are not perfectly aligned or dirty the printer can make a grinding noise. It's even possible that if the paper is not being fed correctly, that the shift might leave segments of it less accessible to the fuser and prevent the toner from adhering to the page.

But I would try using WD-40 to lubricate some of these components and assume the noise and the smearing are separate issues.

is it wavy? if so then it is either the toner cartridge or the fuser unit (heat section) I would go for the fuser unit as the hot roller that makes the toner stick to the paper is only a plastic film. Have you noticed any gray pieces of plastic coming out?

Hope this help you and you can get these machines repaired also please rate me
