Question about Ricoh Aficio CL2000N Laser Printer

1 Answer

We have a Ricoh CL4000DN Laser Printer, which began initially printing with a "smudge" of very fine lines down the left hand side of a printed page. It has deteriorated to the point where the fine black lines have begun appearing more faintly right across the page. Printing colour pages the lines are coloured, much more dense on the left hand side but cover the entire page obscuring some of the test. We have replaced the toners, and attempted to clean/vaccuum the inside of the printer, but the problem continues to get worse. Can you help with a solution please.

I see 2 possible solutions:

1) It could 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.

2) its very common when the climate is humid that the drum and the toner powder of your laser cartridge catches moisture which then produce smudged printouts.to solve this problem u need to blow the hot air dryer on the drum and powder unit.the moisture will go off and ur prints will be fine.

The printer is printing a line down one side of every page it prints


Are you printing a scan or a fax?

If so, you may want to scan the file as a ".PDF" file. This vertical line is sometimes an artifact of receiving a fax.

Need to find # of pages printed.


Press "menu"
Use arrows to scroll to "list/test print", Press "ok"
use arrows to scroll to "Config. Page", Press "ok"
The page is printed, Press "menu" to return to main screen.

Total counter is on this page - top right corner I believe.

Please rate solution :)

Smudge on left side of paper


It seems like your PCU's are dirty and are picking up extra toner. Take them out and look at the green rollers, any extra finger prints or dirt on them? Clean them with a clean paper towel.

Also, check your transfer unit below the PCU's, that may need cleaning or replacing. You can pull that out after removing both PCUs, turn the little screww and look at it. That can also be cleaned with a cleaning wipe or a damp paper towel. There's a little tab that you can turn to free the rollers (they'll still be a little tight) bu then you can turn the rollers to expose more surface area.

Good luck. Be sure to rate the post if it works for you.

Black vertical lines on printed pages


check the "photoconductor unit" (pg 37 in the Maintance manual)

ours was doing it with the magenta and saw a faint 'scratch' on the roller. will attempt to replace and report back if this fixes it.

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.

Color Streaks down length of page


My rep advised that if this problem is occuring when using the feeder, the small glass strip to the left of the glass can have some sort of either high lighter or white out stuck to it. He suggests cleaning this with some alcohol.
