Vertical streak near left edge of printouts....only affects black portion of print image

Prints from our CL3000e have started to exhibit a vertical streak. or smudge like line near the left side....toward the left edge of the prints, but a little bit inside of the far left on the very edge....maybe between 1/2-inch and 1-inch indented from the left margin. I've read the manual and tried all maintenance options available, and checked the toner carts, as well as the "waste" toner container..all look okay. There are also no maintenance messages indicating the need to replace the photo conductor unit for either the color or B&W. I was wondering if this streak might be an indication that I need a new BLACK PHOTO CONDUCTOR UNIT TYPE 125 FOR CL3000. They are $79 on-line, but I don't think we've printed close to the number of copies indicated in the duty cycle for this wondering if there's some "cleaning" function I could perform to clear up this problem, rather than buying parts and swapping to see if that fixes the problem. The printer only gets light to moderate use and is only about 2 years old. We have the duplexer option installed...but this streak is present on single-sided copies as well, so I don't think that's a factor. Any help/suggestions would be appreciated. -- Jimbo

    Any advice on where to find service manuals or other instructions on how to locate and clean the parts you mention (charging wires, LED array)? I've found nothing on this so far, and a call to Ricoh left me empty-handed as well.

    Also, I experienced a paper jap not long before (perhaps immediately prior to) the onset of these streaking symptoms. Is it possible that something (paper bits) got left behind when we cleared the jam? Where would I look for the guilty bits of crud?

    Thanks in advance for any further wisdom and advice you're able to share. -- Jim

    Thanks! I'll take a look inside!

    Thanks everyone. Couldn't find the LED array or charger wires, so decided to just replace the photoconductor's been several years since we bought the unit and multiple sets of toner cartridges have run through the I decided it was reasonable to now replace the PCUs. Problem fixed in about 2 minutes... and more than a few $$$. Been working fine again now for several months.

Get a new printer. I have replaced the photoconductors - both black and color - every 5000 pages or so. I am replacing the printer.

Where best to look will depend a little on the nature of the smudge. If what you're looking at is white, then you might just have a little heap of toner or paper dust on part of the LED array that paints the picture onto the photoconductor drum (look for a narrow unit that stretches full width, adjacent to the drum. Dark marks may, if you're lucky, be down to dirt on charger wires. Both respond well to cleaning with a vacuum and a soft cloth (be very gentle if cleaning the wires). I would be inclined to trust the existing photoconductor unit unless you know it's been abused (e.g. by leaving it lying around in daylight) or the coating on the drum is visibly damaged. A.

    You can find manuals at

    Best guess is that LED array will probably be in the printer body, facing into the slot you slide the photoconductor unit out of.

    Charger wires may be visible within the same slot, but are quite likely to be part of the photoconductor unit itself.

How do you clean the print rollers? All my copies have a long vertical smudge/streak that runs entire length of the right side of the sheet (8.5x11 and 11x17).

It might not be the rollers but the image drum. A bad image drum will sometimes cause streaks on print outs. If you look at the right side of the image drum you will probably see a streak that matches what is being left on your paper. Be careful not to touch the image drum as it will cause fingerprint on your printouts! Of course if the image drum is bad it will need replacing and fingerprints won't matter.

Vertical streaks when printing pictures

vertical lines on prints usually means either the drum's cleaning blade is not cleaning the drum (or the drum is damaged) or the fuser is scored. scored means that the protective coating on the fuser rollers is damaged. I would check the rollers on the fuser (the hot part of the printer right near the paper exit) for any lines on it, if you look at your prints, you should see them in the same location on the fuser. if you do not see any lines on the fuser rollers, then replace the drum.

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)
