jamming in DF-613 on BH 421

[loubsg]

I have a problem with a DF-613 jamming after the paper exits the doc feed. Indicates paper is still in doc feed. You can lift the cover and if resets the jam. The next copy will continue jamming. I have replaced the feed tires and cleaned all the sensors. All sensors show a change of state. I even replaced the doc feed control board. Any ideas?

If it were me, I'd first find out what the jam code is. Then I'd look it up in my manual. =^..^=

It jams after one sheet? If so, is there only one sheet?

when a DF jams after one sheet, it's usually the paper detect sensor. it's thinking theres still more paper there to feed, check the detect actuator

if it happens with a stack of originals...on this model i would replace the reg one way. same as 200-250-350-420-500-501-421 etc etc

in other words it's usually never the sensors...dare i say or never the roller..
