Thank you for the links but both are dead unfortunately, I get a 404 error on both when I click 'Proceed to download'

I'm still trying to solve this problem, can anyone help???

I gave scaling up to 102% a go on acrobat and it seems to be almost perfect. Not an ideal solution but an easily workable one

I've just tested it with printed artwork that was 100% scale to the artwork file. It did shrink, but not as much. It was 375mm wide, so closer to the intend 381, but still quite a way off.

Hi,

I'm trying to print a precise 2 colour job and I've noticed that my artwork is getting shrunk. One element should be 381mm wide, but when printed is 370mm. I'm using the 'actual size' option...

Hi,

I've just taken delivery of a Riso SC5500 rip to replace the SC3000 I've been using with my GR3770. I've been using an old but reliable laptop with Windows XP on it but I can't seem to get the...

The suction unit is out!

Thanks. The drum is good, but the new machine came with a drum in it but no case. It's a HD black drum which I already have, so I'd like to sell it. Not sure how much it'll be worth without a case...

I managed to find the service manual and have removed the following parts:



TPH
Image scanner unit
All PCBs
Guide roller unit
Paper guide plate
Stripper plate

Yes, I have the 9 pdf one. Where do I get the complete one? I have no idea where I got the one I have...

Thanks, after a dig around I do have that manual. Unless I'm being a dummy, I can see anything on removal of the guide roller assembly and pick up clutch. My manual is a bunch of separate PDFs so I...

Hi,

My riso GR3770 died earlier this year and I've managed to find a replacement with only 800k prints on the clock. I don't have space to keep the old one anywhere so I thinking the next best...

I had a chat on the phone with a service guy (at the other end of the country so not able to visit my machine unfortunately). He asked if I had experienced any jammed drums prior to the failure,...

Thank you for your reply, I've been away so have only just noticed it. I won't be able to check until Thursday but will try to remember to press the star key and run test mode 102.

The sensors are definitely clear of debris.



No error message at all and it's definitely not a click Ive heard before in the lexicon of clicks the machine has made in normal use before

Hi,

My trusty old GR3770 has gone haywire. The machine stopped feeding paper and it was making a weird clicking noise before trying to take in any sheets. I removed the double feed wheel assembly...

It's alive!!!

Your driver worked. It was a DPI setting that wasn't adjustable with my old driver.

You've saved my day and a good few handfuls of hair. CHEERS TO YOU!

Hi,

Thanks for your helpful reply. I've been away for a few days so only just picking this up again. I'm using a cable I got from Maplin in the UK:

Hi,

I've successfully been using an old PC running XP to print using my SC3000 to my GR3770. Then the PC died. Setup a virtual machine on my mac with a usb>parallel cable. Installed the same...

Thanks Allan. I thought you were talking about the pressure roller under the drum but I guess you're talking about the rollers that feed the master roll, right? I'll check to see if they're even when...

We had a good look through the path and made sure stuff was lined up correctly. It managed to cut a couple strips after re-loading the master roll a couple times. The error was happening once you...

Hi,

A friend's riso keeps giving a clamp error message and the few times you can actually reset it to make a new master, the master roll misfeeds down in between some rollers instead of correctly...

Hi,

Can anyone help in the next hour or two? I need to know the weight of a GR A3 drum in the plastic case (empty ink cartridge), so I can book a courier. I'm unable to weight it and don't want to...

As the title says really. Nothing in the machine. It prints one sheet, which comes out printed fine, but then gives the error and stops printing.

Never had this before in years of owning the...

Have you got any spare paper sensors for the feed area for a gr3770? Need one to bring my machine back to life. PM me if you do ASAP please

Thanks
