I have a Riso CR1610 and one of the drums leaks like the devil whenever I use it. Any ideas?

    I routinely AVOID calling the technician and do most of the repairs myself. Is there some way I can order the seals and replace them myself? Especially if there is anything available commercially. I HATE paying the outrageously high prices for original Riso parts.

    you may check these seals to your local dealer and maybe they can provide you one or if they dont give you. you van make a remedy by making or inprovicing a rubber tape like as a seal.

Riso CR1610 door was opened before letting down cylinder need to know how to reset and close door

if the drum is partly out and u cant get it to go in or out, u will need to open the top cover and reach in and manually turn the drum by hand until the white sticker on the front of the drum is at the top, at that point it should open. pull the drum all the way out at that point and look strait in the back of the machine where the drum sits, there is a big gear back there, there is a hole in the gear, and a little hole in the frame above the gear, make sure they are lined up, if not, reach back and turn gear by hand, this will set the timing back if it has jumped out

Error E16 RISOGRAPH CR1610

E16 indicates a motor lock with the inking motor. Disassemble the ink pump unit and check for proper rotation of the inking motor itself. This error is caused by a current overload.
Also, remember to try powering on the machine while holding down the reset key to clear all error codes first.

No Ink going to the drum

Good day, there are several reason why theres no ink comming inside the drum. These are the following reason why:
1. Loose rubber O-ring in nozzle of your pump unit.
2. Broken inking hose.(hose size 12 & 10)
3. Clog from ink filter between the nozzle and inking hose.
4. Malfunction on pump motor.
You should verify all those item by dismantling those parts. Just replace any of those parts your drum will surely pump ink again.

Have riso cr1610 - prints for few copies, stops, displays error code E 04

Ink overflow.. On each end of the drum there is adjustments that can be made to the squeege. This is what scrapes the ink through the screen. These scrapers may be applying too much ink or internally too much ink is in the drum. These scrapers can be adjusted from each end. If you have a hard time getting the copy dark enough try to increase the flow of ink through.. this will take away the ink inside quicker. Another problem could be cheap aftermarket ink. I noticed i had a problem with one supplier that the ink was so thin it actually drips out of the drum when not in use.. The only other solution is to adjust the drum internally if the problem persists. This means removal of the drum to adjust ink flow.. This shouldn't be the problem..
