I had a paper jam and cleared the drum as per usual. When I went to slide the drum back in it met resistance and now won't go all the way in. However I can't slide it all the way out either. Can...
Thanks. The checker printed without the line, so it looks like dust on a mirror.
Prints from the title machine have a single thin black line down them as seen in image. The line can also be seen on the master. The TPH has been cleaned and there's no visible damage or dirt. Is...
Thanks. I am currently using a GR 3750 which has serious problems beyond my fixing and there's no-one available in my area who could diagnose/service as it is so old. SHame really as it has been ...
I have previously successfully swapped ink from a CR cartridge into a GR cartridge and wondered whether a sinilar action was possible between other Riso cartridge types. This is a question, not...
Thanks for that. I haven't seen the machine but have asked for pics and video of the problems. They report no service for 5 years and I don't know what caused the problems. I wonder if the screen...
I am looking at replacing my current riso with a second hand EZ570e. it has already printed 1.6 million copies. I'd like some idea of how many more copies I could reasonably expect it to produce,...
It isn't lifting off the drum. I have replaced the master removal hooks as one was broken. There's been some improvement with correction of the timing as it does now occasionally remove a master...
Thanks to all. I re-checked and adjusted the timing properly and things have improved. Now if I can only solve the master removal problem....
Thanks for those suggestions. I'll have a look in a couplke of days when I have some time.
I checked the clerarance and that is OK. In test mode 68 the hook tips forward and I guess thisis what it needs to do to engage with the pressure leaver, but it isn't. I wonder if the signal from...
I recently replaced a worn pressure lever on my Riso GR 3750 where the solenoid hook kept slipping off. Now the solenoid hook does not activate most of the time. In test mode 68 it works fine...
Whenever I try and creat a master the old one fails to be removed. Sometimes the master is caught in the rollers for removal but tears. I have replaced the master removal hooks and set them at 18mm...
Thanks.
Had the same problem on two drums. The link arm connecting the pump motor to the pum,p had come off on one of them, the other motor seemed dud. Replaced the missing bolt on to secure the link armm...
I normally use my GR3750 with A3 drums. tried to switch A4 in an machine tells me I am trying to insert wrong drum size. Do i need to instruct the machine to accept the drum somehow, or is it a...
Is it possible to use CR ink in a GR machine if transferred into GR tube? Are they the same ink in diffeent containers? The compents on the tubes indcates the same materials but it is not clear if...
Does anyone know how long Riso ink can be stored for and still be useable? If the model matters it is for a GR3750. Can ink that is too old damage a drum?
Thanks.

I am looking for a copule of drum support rollers for GR 3750. One that screws directly on to drum housing and the other which sits on a bearing and is help on with a bracket.
Also can other drums...
These are the rubber wheels that sit on the drum support rollers. Would appreciate quote for price ncluding shipping to/in UK or suggestion for UK source.
Thanks.
Have the chance to save some moey on masters but will it work?
I am getting a problem with the master removal - they aren't being removed and I am having to do this manually. I notice the masters that are not removed are often town in the middle.
When I...
