[Error Code] Riso FR3950: clamp error/code T13

[basementlivin]

Greetings from Tallahassee, FL!

I recently acquired a Risograph FR3950 with six color drums. After some promising initial tests (making a half-dozen masters from the scanner bed) with the black drum, I began to encounter repeated T13 error codes.

It's the same every time:

NOTE: at this point, I've tried with each of my color drums and that doesn't make a difference. And no alarming sounds are happening anywhere along the way.

I found an explanation for the T13 code elsewhere, which reads:

• Description:

Does anybody know how to go about resolving this issue? I'm eager to get grooving with this machine!

Thanks in advance,
Erik

First have you tried turning off, hold the reset button, turn on while continuing to hold the reset button until machine has stopped boot up?
Second it is possible that the cutter motor has failed. If that is the case then you will need to remove the cutter unit and replace it. Good luck finding one. I might have a used one I can dig up, but try the reset button first.

Good luck.

knowing how messy those machines are... i would strip down CLEAN ( use Simple Green ) all the moving parts and cutter area... 1 drum at a time also... reassemble.. test...

Will do, Phil. Thanks for that! I'm hoping to dig in over the weekend, so I'll let you all know how it goes.

i haven't found an 'ink' that it doesn't clean...

use a folded paper towel soaked in SG unpark head slip towel under .. repark head .. wait an hour .. clean up mess and you're GTG.
Canon-HP-Bro-Epson is works on all of them.

Alright, I've had time to do some detective work in Test Mode. I tested just about everything I could think of related to the Master Making process and here's what I came up with:

• Test Mode #112 (cutter motor): the motor rotated 360 degrees once when I pressed <START>. It was a very brief rotation, but it does appear to be working.
• Test Mode #5 (master loading button): beeped at 0.5" intervals, indicating NO DETECTION.
• Test Mode #13 (clamp safety switch): beeped at 0.1" intervals, indicating DETECTION.
• Test Mode #28 (master removal sensor): no detection.
• Test Mode #29 (master loading unit switch): detection.

It appears to me that there are potential issues with the master loading button and master removal sensor. Does anybody have experience addressing these issues?

Thanks for helping me narrow it down this far!

Best,
Erik

First, a warning: I have been out of the trade for a couple of years. So hopefully jermyth and Phil will prove me wrong.
But that you checked all those components in test mode makes it sound like the main board is bad. Test mode is fine for testing individual components, but if those components are not working with the proper timing (which is controlled by the main board), wrong and stupid things will still happen.
In reality, I'd wait for jermyth or Phil to get back to you before you do anything. God luck.
