Mark,
I have resolved one issue... Cleaning with Acetone didn't do good enough of a job. After re-cleaning the carrier with mild detergent and scotchbrite, Drying with fresh clean cotton dish towel, I am not getting the paper jam indication upon the first pull, and am not getting residual toner on the sheet. Poor conductivity at first, I think. However now, when I print from the PC, the carrier pulls in to about.75 past the trigger hole, and stops with a jam. Is this likely due to the high resistance of the pullup resistor (30.1k) preventing the trigger from working?
Thanks,
Roger

Roger,

This usually happens if the NPIS doesn't see the hole in the carrier. Did you remember to drill one?
