Ricoh aficio 1027 Printer leaves harsh black streaks on copy

There are three likely causes for your streaks:
1. If they only happen when you put originals in the document feeder to copy or scan, and if the lines stop about 1/8" from either edge of the page, the problem is dirt, correction fluid, or debris on the small glass just to the left of the large platen glass. Clean this strip of glass and your problem will go away. If you can see the Wite-Out or other dirt, just wipe it off with a dry rag... otherwise, clean the glass strip with alcohol.

2. If the marks are solid lines across the page, the problem is the photoconductor unit (PCU). This unit is a whole replaceable all-in-one unit -- replace the PCU and that will fix your problem.

3. If the marks are slightly uneven or if they feel raised, the problem is most likely a scratched or damaged hot roller, in the fusing unit. If this is the case, you'll need to have a service technician replace your hot roller to fix the problem.

Thanks for using FixYa!

I have long yellow streaks on copies.

Hi, Sounds like the yellow PCU is faulty, pressuming the streaks are vertically down the page.
If they are horizontally across the page it is probably another issue.

Ricoh Aficio CL 2000N printing problems

If the colors are good and solid with no fades, only black streaks, then black is the culprit. I suggest replacing the black cartridge.

Hi there it will be either the drum unit for the color streaks you are getting or the fuser unit. Check the drum units for the streaks on them also check the fuser but the clue is when you have the streaks in different places. Most likely to be the drum units. You will need to replace.

Thanks J
