Question about Riso Office Equipment & Supplies
I ran our Riso RZ220UI in test mode and printed out a checkered sheet and square sheet and they printed flawlessly. When I scan something, however, I have a series of solid bars on one end of the page, slightly varying in thickness and space apart, but same length. It is being burned onto the master. Cleaned glass, put white posterboard behind scanned item... same bars in the same part. It is a scanning issue but I can't figure out what to clean or how to fix.
You have to change the whole unit of your led light. the bar with all those led lights are attached or soldered. hope to be of help.

Can't image it being anything but scan glass, if prints are fine, are you sure you cleaning scan glass(inside of where originals are fed)?
If so then scanner lamp faulty, but I've never come across it myself on this model.

It is a cartridge problem. Solution for my hp 3645 (I have the same story as bb18, but different printer) was to remove color cartridge!
The printer is fast now, of course it does not print in color :) (I`m waiting for a new color cartridge) Good luck,

It is not in the glass. More than likely it is in the rollers of the ADF feeder. If you open the cover of the ADF feeder you can see there are 3 screws (! is found under another small cover furthest to the back of the machine. Once these three screws are removed you can left the entire ADF feeder from the unit. You will then be able to clean all the rollers. Do not use alcohol as this will dry our your rollers and cause them to eventually crack. Just use soap and water to clean the rollers. Then reinstall the ADF feeder assembly back on the machine.
