Re: [Homebrew_PCBs] Re: DLP MCU version troubleshooting, help needed

2015-04-06 by Roger Blair

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
