Riso FR3950 doesn't make masters, covers entire page in ink

The internal check board print worked fine, so that's good at least. I was thinking of taking the scanner out and putting a scanner from another FR. Is it as simple as just switching them out or do I need to do something more?

What is the FR test code you used to do the internal print (the check board pattern?)

It's 120! And 117–119 are different line patterns.

First the reset is power off, hold reset/clear button and turn on the machine, continue holding the reset all button until the machine comes to ready.

Second if that don't help then replace the scanner ribbon cable. You don't have to replace the whole scanner, just the flat cable between the scanner and image pcb.

Good luck.

Tried it and it has since worked. If it all goes south again, I'll swap out the ribbon cable. Thanks!
