If the lines is same direction with paper way that means the problem with laser beam pass ( check mirror and its window)
if lines are perpendicular to the paper direction the drum is the problem ( check all fuser connector first )

The small scanner glass (not the full size glass) has some dirt on it. Use a lint-free cloth (not paper) with alcohol or Windex and clean the glass. This should help.

SOURCE: How do I clean or replace the drum on a Ricoh

The drum unit on these models is a complete replacement unit. the drum can only be cleaned by removing the unit and then there are some screws to be taken out. two on the back plat and two on the front. if you take these cover plates of the unit will split and you can remove the drum(Blue roller) and under neath there is a charge roller as well that can be cleaned.. only use water on the black cahrge roller and gently rub with a cloth till clean. The drum with a very soft cloth and some liquid brasso may clean it up or get rid of the scratch lines but if they are too worn the drum needs replacing. you can clean the scanner glass and the mirrors underneath here as well.B0392201 is the part number for the Drum unit which comes as a complete unit. you may need to purchase the developer for the drum init as well B0399640 is the part number for this. hope this helps >>>A

SOURCE: I am getting thick black

Dirty print out is basically due to cartridge related issues. Take out the cartridge and clean its drum/ (green roller) with a dry, soft, lint-free cloth. The drum is usually located under a cover. Checkout for any spilled toner inside the printer and clean it also. Print a few pages so that the parts get further cleaned. I think, this would solve the issue.

Moreover, black streaks (thicker lines) and dots etc indicate faulty PCR Roller which is located behind the green drum inside the cartridge. Try replacing the cartridge or get the PCR Roller changed by a professional.

Let me know if any further clarification is required.
GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

I would have to say that you are having a problem with your drum unit and or the developing unit. Most likely the problem is in the drum unit. You have a line going down the page. I would replace the drum unit and try to clean below the drum unit... Good Luck..

Bold black lines across the paper when printing,scan or copy not on faxing


I realise this is probably too late for you Janet and you will have bought a new drum unit by now or replaced the printer! The three lines appeared on my print-out from a new drum I installed and after investigation it transpired that there was some toner residue that had dried on the drum (from testing at manufacture stage probably) and reprinted three bold lines on a sheet of A4. The solution is to use a soft piece of cloth and rub the lines off the drum through the gap at the front of the drum unit. The drum can be rotated by turning the gear cog on the side, then once the reside has been removed from the drum and it is clean, the lines will have disappeared. I wouldn't use any solution on the drum, just gentle rubbing should suffice.

Our Gestetner DSm645 gives Dark Copies..........


Sounds to me like the drum needs replacing, and likely the developer too. There is probably a haze of toner still on the drum. You can check by opening the right side cover and looking at it. Is there toner on the drum (green cylinder). It may not be too obvious depending on how dark the copies are. GENTLY wipe a tissue across it after making several copies - it should be clean if the drum is functioning properly. If it is, it could be the fuser that is wearing out, but I'm leaning toward the drum. As I said, if you need to replace this, it is a good idea to do developer at the same time, because these machines tend to be a little sensitive.

Lines on page


As far as copying goes, it could be lines on the scanner glass. You might want to check that out.

Do you have any way of checking the condition of the drum on the cartridge to see if there are any lines on it. Find the drum cover protector by removing the drum cartridge straight up, lift the drum protective cover and see if there are any lines on the green surface. Try to keep it out of direct light as much as possible. Make sure you lift it straight up so no toner or developer spills out.

I've seen a few cases where the cleaning blade on the drum is defective. Usually you can return them and get a replacement at no charge.

Prints black vertical line at bottom of page on every print. HP 8550gn


This should help -

Developer streak
Developer streak is characterized by a line of dark or missing toner
that stretches from the leading edge to the trailing edge. Replace the
toner cartridge corresponding to the color of the developer streak (for
example, if the streak is magenta, replace the magenta toner
cartridge).

Repetitive defects troubleshooting
Repetitive defects are defects that occur in the same vertical position
on the page, but not necessarily on every page. Most repetitive
defects are caused by problems with one of the following, and are
indicated by the positioning of the defect on the page:
 developer roller (at 38 mm)
 charging roller (at 44 mm)—see additional information under
“Charge roller set” on page 454.
 cleaning roller (at 56 mm)
 developer DSD wheels (at 65 mm)
 transfer roller (at 66 mm)
 transfer drum (occurs once per 11-by-17 inch or A3-sized page,
or every other letter- or A4-sized page)
 fuser (at 150.5 mm)
 imaging drum (at 195 mm)
 transfer belt (at 222 mm)
