Could be bad cartridge leaking. Drum is in the cartridge and if the drum wiper is not doing a clean wipe toner will drop onto paper. Take out cartridge and over a sheet of white paper tap the cartridge with you hand, if toner drops you have a leaking cartridge. Also could be fuser area, they get dirty and leave lines or the teflon coating wears through and leaves a line, depending how old this unit is.
How do I clean white or black spots on printed documents?
Description:First make 10 to 15 copies of a blank, white sheet of paper.
If you still see the spots on printed documents after making multiple copies, clean the drum unit as follows:
Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
the print sample in front of the drum unit so you will know the exact
position on the drum that is causing the poor print.
Turn the black gear on the drum as you check the surface of the OPC drum.
The OPC drum is photosensitive so do not touch it with your fingers.
you find the substance on the drum surface that matches the print
sample, gently dab the surface of the OPC drum with a cotton swab that
is lightly dampened with isopropyl alcohol.
Do not use a scrubbing or wiping motion because this might damage the drum.
Do not try to clean the surface of the OPC drum with a sharp
object, such as a ball-point pen, because this might cause permanent
damage to the drum unit.
If the print quality still has not improved you need to install a new drum.
Unfortunately when it comes to toners and drums there isn't much that can be fixed with cleaning. It sounds like either your toner cartridge is worn or defective and spilling toner, or your drum could need replacing and therefore is acting up. To check if it's the drum, pull out the drum unit and look at the drum roller (but don't touch it!) you should see streaks or color changes on the roller in places matching where the smudges on the paper are if the drum needs to be replaced.
My bet is on the drum. Drum units are fairly easy to get a hold of, since it is a "replaceable" part of the printer. And if you can install the toner you should do fine with the drum unit as well.
It sounds like your drum unit needs to be replaced. Do the smudges look characteristically like a finger print? Technicians have a rule of thumb. Replace your drum, developer compound and general service the machine as often as you service your car. Assuming you do service your car as often as I do, it should be after every 25,000 copies. If the machine has never been serviced then its time you did.
you don't mention whether the document you are copying also appears on the paper.If it does you could have 1 of 2 problems- The drum cleaning system could be at fault or- the fuser roller has picked up some **** easy test...... run copies and when the 1st copy edge appears switch OFF. This is a crash stop.Now examine the sheets in there.Is the stripe on the copy before the fuser (Heat) roller? If yes you could have a drum cleaning problem, usually fixed by changing the drum module.If no and the stripe appears after the heat roll, the problem is with the fuser system,dirty rolls etc. There are a number of other problems with stripes, but you have to start somewhere! If the document does NOT appear on the copy, forget all above, could be scan or ROS problem
A smudge across the copy can be in many different areas.
The drum cleaner may be the problem as you indicate.
It may be a piece of paper ripped of dragging across the surface of the paper causing the smudge.
Also the fuser roll coating may be very worn and causing that. One thing to try that can show you if the defect is on the drum cartridge, is start to run a copy, After the paper feeds and this is timing, shut the machine off when you think the paper should be about half way through the copy cycle, then see if the copy defect is on the unfused page, If it is smeared before it reaches the fuser, it is in the cleaning section, if it is not smudged, then it is most likely the fuser rollers are needing replaced.
First look for a paper fragment in the path, step 2 is to shut the machine down in mid copy and see if the defect is there.
The fuser is the hot area of the machine in the exit area, If you can take a flash light and look in there and see if you observe wear or heavy toner buildup on a roller then obviously thats the problem.
Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.
Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).
Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.
