Canon CLC3200 DADF jams, it doesnt even take the paper!

[jonbonse]

Hi all

I seem to always struggle with these DADF units!

The green LED comes on when insterting the document in the doc feeder, press go. I hear a motor but the pickup rollers dont come down to pickup and straight away I get the jam message to open the covers.

I have removed the drive assy and checked paper paths and blew out sensors.

I have used the dip switches to test the operation of the pickup rollers and they seem to work this way which to me cancels out the motors. .

Has anybondy else encountered this or let me know what I should do next??

The Entire Pick Up drive unit is noted to fail in this model/ it is a pain is the but to remove & replace
I'm not talking about the Sep.unit here.

1. the Pick Up drive assembly may have a cracked gear that is not visible
2. u need to make sure that the unit is put back in correct when removed
3. when u use dip switches to drop p/u roll unit , does it drop all the way down & and move back up when u push button
4. that dip sw/operation to drop down p/u roll is for easy release of Sep Pad unit.







It may be necessary to advise the operator that the pickup unit cover needs to be opened before removing jammed paper. Opening the cover releases the pressure on the DADF transport rollers in order to ease jam removal.

Separation Drive Assembly (FG6-3963-110). When replacing the separation assembly ensure that the actuator for the pickup roller is set as indicated in the photo.







The teeth of the 14T gear in the separation drive assembly can chip, causing abnormal noise and paper pickup jams. An improved separation drive assembly is available and incorporates a 14T gear made of a different material to prevent the teeth from becoming damaged.

The 14T gear will not be available as a service part. The gear is press fitted onto a shaft and is not replaceable. If you experience the symptoms as described, replacement of the separation drive assembly is necessary

The new Sep Drive unit must be installed with a new Doc. P/U Unit/ they are not interchangeable

DADF-K1 / XKX15722 and later will have the new modification/
if your DADF Ser# falls in for later u just need to replace the Sep. Drive Unit

If this your case below read info





imageRunner C3200 / C3220 The DADF Pick-up Rollers Drop to Feed but Do Not Rotating.

The Pick-up Rollers for the DADF drop down but do not rotate to feed the paper in, a jam is indicated in the DADF.


Check that the DADF inlet sensor flag (SR40) isn't hanging up or have a torn piece of paper blocking it.

If the mylar sheet (denoted by the red arrow below) is either crushed or missing, the ADF Close/Open Sensor (round black ball mounted on the right side of the feeder denoted by the green arrow) will not actuate when the DADF is closed. Therefore, the machine acts as if though the DADF is not present. There is another mylar sheet located on the left side of the reader unit that serves no purpose and can be used in place of either the missing or crushed mylar shown below.

Thanks for all the support!

If I use the dip switches to drop down the pickup rollers, they work and also when I use the dip sw to make the pickup rollers go up.

ALso using the dip sw to make the sep roller works. . . .

Just doesn't do it when you try copy notmally.

The document is recognised on the DADF and the mylar covers are on the underneath side of the dadf. . .

hate to say it but , Separation Drive Assembly/ needs to be replaced / see pic notes above/
that is what drives the p/u rollers/ I personally stopped replacing them/ the reason is there is a shaft on end that needs to be locked place , when u remove old unit- if u don't have it in correct position when put back and re-assembled it will not work

I now replace the entire Document Pick_up Assembly / that pain in the ass part (Separation Drive Assembly)
is already included in it/ saves a lot of aggravation

that pic below shows entire unit
3200 has a DADF-B1 I believe
FG6-3950-000
