Question about Ricoh CL4000DN Laser Printer

1 Answer

Black lines down page

I have a ricoh cl40000dn, when I print I get 20 lines (1in thick) on the left side, and then on the right side in 4' and 6' another line (2/3 thick).  These lines run top to bottom.  I have cleaned the two rollers, and have checked the PCU and did not see any scratches.  It is only black, not color.  Any idea's on what I should do or try next?

It must be the black pcu , the cleaning blade picks up dirt and causes these lines , it can also be the black developer giving you trouble , if you want be very carefull aand strip the pcu open you will see the lines only on the inside and not from outside , then you will know if it is developer or the cleaning blade

I have a Ricoh Aficio CL3500N When I print a vertical page there are thin black lines going down the left side of the page. What causes it?? And what can I do??


Hi, thin black lines are most likely (but not definitely) caused by something in the black PCU (photoconductor unit), either the drum or the charger. Replacing the black PCU will likely get rid of your lines. The Ricoh code for a black PCU if you don't already have one is 402448.

My Ricoh Aficio CL2000N is printing several faint lines


Couple possibilities:
Fuser hot belt has wear lines transfering to the page
Black pcu needs to be replaced
Transfer unit is not being cleaned properly and needs to be replaced.
Remove each of these assy and inspect them for wear or lines that corespond to the lines on your prints.

Kyocera Mita Ecosys PS 1010 all prints have thick and thin line down left hand side A little while back the printer started printing completely black sheets. Fixed by turning off and then on again. Since...


Try cleaning the charge wire. Move the lime green plastic handle from one side of the image unit to the other in the groove. If this doesn't work you'll need a new image unit.$$$$$. note: Make sure green handle is moved completely to the right when finished or black line will occur.

Black Lines running down the right side outside of the print area


It may be the fuser. Take it out and inspect the roller on it:

  1. Switch off the device, disconnect the mains plug and wait for 30 minutes before continuing.
  2. Ensure that the bypass tray is closed, or you will not be able to open the front cover.
  3. Open the front cover by pressing the release buttons as shown.
  4. Pull the front cover down towards you.
  5. Disconnect the green plug - squeeze the sides of the plug and pull.
  6. Push the left and right levers outward to unlock the unit.
  7. Pull the unit towards you as shown and lift it clear of the device.
  8. Check the roller for wear marks, If so replace it.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Ricoh aficio 1515f printing dark line down left side


If the print can be rubbed off then this suggests the fuser unit is not working correctly. It could be that the thermistor is covered with toner and making the machine think the fuser is hot enough when it's not.

The black line could also be caused by the fuser if one of the pick off fingers is coated with toner or has worn into the Teflon of the roller.

Does the machine show the lines when you print a page from memory - such as a counter or config page? If not, this would suggest the optical path is dirty. Try cleaning the glass and look at the mirrors inside the scanner to see if they are dirty/dusty.
