Both problems sound like an issue with the thermal print head, although it could be an issue with a drum as well.
Do you run one through at a time? Do you have to flatten it a lot for this to work?
I wasn't aware that the RP3700 could be interfaced with anything more recent than Windows XP.
Will do this, thanks for the tip. Just out of interest, could I not just compare the drums without putting a confidential master on and running prints? If there's a noticeable difference and problem...
Sorry for resurrecting this, but I never found the part you both mention. Is this the drum chuck/coupling you mention in the photo? How can I check if something is off (the reason why prints are...
Hello,
The separator in my GR 3750 is leaving a mark on prints. I've never had this issue with letter-sized prints (I think not, unless it was not as noticeable), but it is really bad with...
Certainly, and thanks for asking these questions, it's useful to rule out what's going on. Is there still something you've seen that suggests this drum is not to be used with color? Otherwise with...
I have 6 other drums that work fine (so only T4 error with this drum), and this drum worked fine before I changed the ink tube (from OEM Hunter Green to OEM Hunter Green). What is it about the tube...
Thanks for the reply. I've attached pictures of the ink tube installed in the drum. I think they're pretty ordinary shots, nothing stands out as being out of place (the ink cylinder is installed as...
Hello,
I have a color drum that gave a T4 error shortly after changing color ink tubes. I understand this involves an overflow of ink inside the drum. I tried to reach inside and clean around the...
Is there anywhere this is explained using pictures? I'm worried about messing it up. Also, if I want to clean the screen should I do that first, as presumebly all the bits will fall into the ink...
I'm constantly worried about exactly that. I can't afford a newer model though. I'll check what you mention.
I sort of figured that, but also wanted to sneak in an opportunity to get someone to confirm whether or not the configuration in that photo is correct, as I want to do some maintenance to my Riso in...
I agree. Any ideas as to what could be wrong with the drum that would cause this?
You'll have probably figured this out by now, but check this thread if not: http://www.copytechnet.com/forums/digital-duplicators/76495-riso-computer-interfacing.html. You'll need an interface cable,...
There's definitely drivers for that model, they're listed here: RISO Download Center. Which version of OS X do you have? It looks like the most recent supported version is 10.8. In my experience with...
Just realised I was silly to think I could simply reach in to scoop out old ink. I still don't understand how far I should go in disassembling the drum to accomplish this though.
Hello,
One of my GR drums (red) prints to the edge of the paper, causing a good portion of the print to appear as if it was full bleed. I'm guessing this is a problem with registration, although...
Thanks for that. Can this be done while the drum is on the rails (or am I thinking of cleaning the screen)? Also, when you say "drum shell," are you referring to the drum covers, as they are called...
Hello. I have a few GR drums that were likely last used a few years ago with ink that has since gone bad. I've installed new ink cylinders but there is still probably quite a bit of bad ink in there....
Makes sense, although it sounds as if it would certainly be more than two years old. I've message some sellers on eBay asking for the date stamps on the ink they're selling and they've provided...
Thanks for that information, very useful. The few old ones I had that I was worried about are date stamped in a completely different format (i.e. 4H644H1) so they must be quite old.
Some of my...
Hello,
I've found one topic on the forums about Riso ink shelf life but just wanted to confirm a few things. I've read the normal shelf life for ink is about two years, at which point it begins to...
The issue with mine turned out to be exactly that, a bent "lower safety switch activator" (part #15). I couldn't bend it into the correct position, so I had to tape the safety switch itself it...
