Question about Riso RZ220 Duplicator
I have a Risograph RP3100 that we have not used for a couple of months. When we tried to use it there is what I would call a dry spot on the drum and the text in that area does not print. I tried pulling the master back and rubbing the area with alcohol but that did not help. Any ideas????
You can clean it, thats a good idea but,,(and this is messy) roll back the master.. take out the ink cartridge, use a rod to squeeze some ink onto the area, and smooth it out into the screen with a plastic scraper.. Lay the master back over. Keep scrap paper around and print a big black square and run a couple hundred sheets through.. This will work. Messy but will work. If you don't want to manually put some ink on the area.. Print a large black square and run a couple hundred sheets.. see what that does.

WD40 spray and rub in the area with finger where you don't get image works great !! Thank you Dermot for your help.

SOURCE: Risograph Drum
Try run a hundred copies at slow speed and full density/ pressure.
If that fails get a can of WD40 and spray it under the master, then rub the area with your finger. this will desolve the dryed ink on the drum surface.
