Not sure what you can do if the sensor is broken other than trying to find a replacement part or a parts machine that has a donor sensor. Sorry I can't be more help on this one. Good Luck!

I eventually discovered my model of GR3750 was not compatible with the SC7700 interface, hence the multiple beeps.
If you are able to get an interface card for the 3770, and Riso computer interface, it will only work with a version of Mac OS X that supports appletalk (10.5 was last version). I recommend using an...
See this post here: it may be the safety bar switch:

Ok, I have cleared off all the excess ink. What's next here? Wondering if I should now just try test mode 101 or work on squeegee roller adjustments?
I do want to clarify, when I ran my test...
Thoroughly deep cleaned the drum cylinder inside and out as well as the screen. How can I rule out that this isn't still an issue with the screen? I ran a TON of prints to try to get rid of any...
Wonderful! I am glad you got it sorted - that one broke my brain for a while so I am glad that helped.
There is a metal safety bar / actuator below the paper feed area - under it there is a safety switch that if the bar is depressed - it will throw the "check paper feed area" message. That may have...
So sorry for your buying troubles!
The good news is that the cable for the Riso SC3000 SC SC II cable is definitely compatible with later models of the SC computer interfaces. The bad news is that...
@Iowatech good eye on that sensor. It was definitely out of adjustment and now back to spec. Now that I think about the issue, I "introduced" a new GR(w) color drum to the machine after cleaning it...
I received a T11 error and saw that the gear for the print pressure adjustment gear was sitting just below the pressure control motor gear so just spinning constantly until it times out and errors...
Successful deep clean!!! It was the drum shell: Super clogged with ink. Multiple rounds of towels soaked with mineral spirits on the outside of the drum shell AND inside, some toothbrush scrubs of...

UPDATE:
I have opened up the GR(w) drum and wanted to share two videos below. Does anything look problematic? I am not sure what the roller is called that sits between the doctor and squeegee...
Sure thing! Please post an update in the forum if you can. It helps other forum users if you follow up with the steps you went through to solve the issue. Thanks!
Hi, I just sent you a private message regarding shipping a drum from U.S. Thanks!
Ok, wonderful. I appreciate the clarification. I am going to to do all the suggested cleaning that has been advised here in this thread and report back. I will try and document the steps with...
The ink I am using is not old but the drum may have been sitting for some time before I purchased it on eBay. I thought the solvent got all the holes unplugged but maybe not. A good clean inside and...
Yes, I think it certainly wouldn't hurt to do this with this drum. I am assuming that the Tech Manual should be the best guide for disassembly of the drum? And to clarify: are you saying I should run...
Not able to get a picture of it for you but when I shine a light in there, I do see beading on the rollers. When I compare it to my working Black drum, the Fed Blue seems "blotchier" if that makes...
I did a "deep clean" of a Federal Blue GR Drum and then installed a new screen. I am still having inking issues with this drum. I soaked the drum with the old screen on with mineral spirits (covered...

Hi Everyone,
Are there any tips or suggestions for inking a GR(W) drum with a newly installed screen? I am using a GR3750.
I don't want to mess up all the prep, cleaning, and hard work it took to...
SUCCESS!!! I installed a system PCB from a GR2750 which had one of the supported SC7700 ROM versions (V6.02C). I also had to change the SW2 switch on the system PCB board for A3 printing.
Before...
I am not convinced it is the driver settings, but maybe so since as far as I can tell the FR3950 driver seems to be for only GR3750 and 3770 machines as well?
With the printer queue open, can you...
