Chosen Solution
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: [IMG]http://i64.tinypic.com/2qvuvjl.jpg[/IMG] http://tinypic.com/r/2qvuvjl/9 [IMG]http://i64.tinypic.com/2q3sx0z.jpg[/IMG] http://tinypic.com/r/2q3sx0z/9 Curious if anyone has any suggestions for removal tools other than gripping with fingers.
It definitely looks like a LIF, Low Insertion force connector. If it were soldered in place the ribbon cable would not have the blue reinforcing plastic on one side. The photos did not seem to show any corrosion, but there may be a little corrosion that is causing the contacts to stick. If it is corrosion, you can try cleaning with alcohol to loosen the ribbon cable. If you can get one side to move but not all of the ribbon cable then that is corrosion.
