Question about Ricoh Aficio CL7000 Laser Printer

1 Answer

We get "dirty" black and white copies, with smudges on the paper.

The technician changed the drum, and we have changed the fuser unit. Does it need cleaning? If so, how is it done?

Printer leaving black smudges and streaks


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.

Black smudges down left side of page


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:

  1. Remove the drum unit and toner cartridge assembly, and then remove the toner cartridge from the drum unit.
  2. Position 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.
  3. all-ug-19.gif
  4. 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.
  5. all-ug-20.gif
  6. When 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.
  7. Note
      • Do not use a scrubbing or wiping motion because this might damage the drum.
        all-ug-21.gif
      • 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.
  8. If the print quality still has not improved you need to install a new drum.

There are smudges all along one side of the paper, changed the toner and still the same thing


Hi,
The drum is probably dirty. Try removing the toner and cleaning with a clean dry cloth. Don't use a damp cloth.

When printing dark line down copy


A line down the copy can come from a dirty document scanner lens.
Usually white out or wet ink will smudge on the document scanner. Opening the document cover check the scanner for a dirty glass. Some document feeders have the white roller on top of the small glass window. They have delicate plastice retainers that hold the roller on both ends. Extra care needs to be taken if this roller is removed.
Clean the roller and the glass with wet towel. Shine a flashlight on the glass to see if there are anymore black marks on it.
Use the finger-nail to run across the glass and make sure no debris is on it. Even a spot can make a line on the copy.
Also, a bad fuser roll can cause a black line on the copy. A defective drum unit can cause a line on the copy as well.
If all else fails place a Xerox service call for this problem.

Smudges on paper and ink is light when it does copy correctly.


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.

Horizontal black and white lines are coming on copy


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

PC-65 (Canon copier)


A smudge across the copy can be in many different areas.
Some ideas.
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.
