Black Spots all over my copies

I just recently began seeing black "blobs" on my copies, very random at first, but now they are all over the page. they are not always in the same spots, they will be anywhere from just one line down the page of spots to all over the page, to none. I can find no rhyme or reason. Any suggestions

Re: Black Spots all over my copies

There are lots of things that can cause this. Inspect the fuser assembly & verify that there isn't any teflon missing from the upper roller & that the lower roller is clean. The spots can also be caused by a build up of waste toner in the cleaning assembly, causing excess toner to be dropped on the copies as they pass under it. The cleaning assembly would need to be removed & cleaned to correct this. The spots are not always in the same place - but are they the same pattern? A worn drum assembly can cause spots that are usually a repeating pattern but located in different parts of multiple copies. Dirty corona wires can also cause random spots & rewiring the coronas would solve that.

Black spots on each page

A laser printer has its rollers (which I believe you said you cleaned...very important) and the cartridge you put in the printer has rollers too! Carefully check them and the wiper on the cartridge. If all of those things are clean, then you should get clean copy!

I have random black spots on my paper, some flat, some raised. Looks like blobs of toner.

Drum was improperly cleaned; residual particles remain on drum.
Try to manually clean the drum and do a cleaning procedure as in your manual. Replacing the cleaning module is the last thing to do if nother else works.

Printer sqeaks loudly when printing. Also there

Sqeaks are hard to fix over the computer but if the black spots are random change the toner cartridge. If they are 3 or 4 to the page change the drum.

Oce 3121 coping machine make random black line shadows

if you are getting copy quality issues on all aspects of the machine, IE, printing, copying, ADF, it looks like then you might need a new drum installed. please contact your local service department for service and make sure if you need supplies, to have those on hand before calling a tech to come service the machine. drums, developers, and toner are considered a supply item and are NOT carried by technicians unless otherwise stated in your local contract.
