C75 won't duplex

[adriansto]

After further testing entering 077-115 in the component control I get the High Reading, them inserting a piece of paper and reentering the the 077-115 I don't get the low reading. It is a new sensor that was installed also. Does this point to the PWB needing to be replaced?

Follow the procedure from edoc.
It say to check led status before change the mcu

My C75 won't duplex. it prints the first side, goes through the duplex start to go into the transport roll and stops. The transport roll isn't advancing the sheet into the pre registration roll. No fault codes, just clear the "jam". Checked sensors for obstructions don't see anything.
What do i look for next?
TIA

on brass bushings it's best to use a light oil not WD-40 ... decades ago Canon and Xerox goth made a statement that WD-40 DRIES out the bushing causing wear and squeaking.

I recommend using TriFlow oil. it has teflon particles in it and doesn't dry the bushing out.

WD-40 isn't actually a true lubricant. WD stands for "water displacing" and its main use is as a solvent or rust dissolver.
