I have a C1 and my web cleaning roller ran out, so I replaced it with a partial roll that I had acquired with a bunch of parts. The web is properly threaded between the plastic detector feelers, and when the web assembly is installed, the sensor is not being blocked. There is nothing stuck in the sensor that would be giving it a false reading.
I have cleared the counter: COPIER > COUNTER > DRBL-1 > FX-WEB
The web I installed is about half consumed, but it still thinks the web is low, and it gives me the E005 error code after the 3000th copy and shuts down. I can clear the code and it is good for another 3000 copies!
Any ideas what to try next? There must be something I missed, as it was working fine before the web ran out.
