adf 3010

[Mark Bbb]

Do you have good experience with swapping adf 3010 from mpc3500 to a mp4000?
I used to do this succesfully but now it indicates "original jam" at skew correction sensor.
I had the intire feed in unit (containing the sensors and paper feed rollers) swaped, no good.
Swaped main board, no good...
Could it be the swaping between different machines that cause this?
I do interventions and maintenance on those ADF's here in my atelier (easier to work) and when it is repaired, of it goes to maybe another type of machine.
Thank you for you reply.

i look at different sites and says doc feeder same for both copiers should work. First question was it working properly on copier you took it off. try using adf input check to see it sensor for skew is working properly.

copierman:
client complained about jams.
So, it was working +- fine before my PM (replacing guides, rollers, cleaning sensors).
Immediated after power on (on a c4000) it gave J001 (remove original from feeder).
Seems to be sp6007 -11 (skew sensor) that indicates 1 (in stead off 0).
So swaped the whole "above" feed in unit, DF main board.
(Other DF's are working fine on that mp4000).
I have used a vacuum cleaner to clean the sensors, i think i might have caused a stratic blast somehowe .

static blast

also replaced harness (to the main board) of the above feed in unit.
Keep saying jam at skew sensor ...

oh my!
The black reflection hole (of the skew sensor) on the black feed in guide reflect the photo sensor beam.
That is because i forgot to put in the adhesive anti-reflection path.
Thanks for your time, copierman.

glad you figure it out what was wrong
