Qss2910 Sees The 120 Carrier As If It Is The Slide Carrier

[Johnson Camera]

We have a QSS-2901 SM. When we mount the 120 carrier, the software tells us to remove the mount from the carrier. If you Reserve (F) the error, you can see that the software thinks the carrier is the 135/240 slide carrier. We have cleaned all the contacts. Also disconnected the ribbon from the board in the carrier and checked for continuity or short-circuit.

If the machine is started with the 120 carrier mounted, it will recognize it ok.  However, if you get a film jam and have to remove the carrier, the software doesn't recognize it correctly when you remount the carrier.

Since the three connectors that identify the 120 carrier are Low, High, Low, and the slide carrier is Low, High, High, I would assume that it isn't dirty connectors causing the lab to see a erroneous High signal.

Any suggestions?
