Canon IPF 750 Plotter motherboard stubborn ribbon cable
Greetings all. I am replacing a motherboard on a Canon IPF 750 Plotter. I know a PIXMA MP190 was selected but I had to choose something. All cables have come off fine with the exception of one thin ribbon cable. The two connectors above it had lift up locking levers alas this one does not. Even spoke with a Canon technician whom would have to see it to be certain but was of the opinion that it should just pull out.
I can see any indication on the connector that there is a way to unlock this cable. I've pulled pretty danged hard on the cable end to no avail and want to avoid damaging the cable. The PCB board itself also flexes quite a bit which is concerning.
Here's a couple pic links for discussion:
Curious if anyone has any suggestions for removal tools other than gripping with fingers.
