DF Multifeeding on Canon IR3245

[Iommanxman]

I have had lots of problems with a Canon IR3245 and multifeeding from the DF. I have changed the sep pad even though it is a new machine. I have even swapped the whole df with another machine. We have several of these machines in the field and one by one they are all multifeeding in the DF from new. Even with new A4 80gm paper! Seems to be some kind of a design fault. I was wondering if anyone else has had this experience so I can feed this information back to Canon?

Did you also move the white pressure plate on the underside of the sep pad to the new sep pad. Thats the only time I've had problems with that whole series.

Are you sure you are thinking of the right DF? The DADF on the IR3245 range is a totally new DF design. It is a DADF U1. The sep pad on this range is totally smooth. Whereas the others in the range are slightly textured for grip. I think this is more of a design floor rather than a fault as it is A:- a new machine and B:- I have swapped the whole DADF with another new machine. Thanks for you help though.

Does an Ir3570/2270 sep pad fit by any chance?

[Iommanxman]

I am not sure? I will order one to check. Anything is worth a try at this stage. Thanks.

I have just had a look in the parts catalogue. It seems to be totally different. The DADF U1 is totally new. Nothing like anything else in the Canon range. Totally new design, which doesn't seem to work.

Sorry one other thing may I point out. This is happening to ALL the IR3245's in the field not just one or 2. They are all multifeeding from new.

I was thinking of the 4570 DF. My mistake. I don't have enough of the 32 series to have had problems but would love to know the outcome.

Some illumination...

This document feeder is very much like the one on the iR2022. It shares the same sep pad. This feeder is nowhere nears as robust as it's older counterparts on the 4570 or 3045. Get used to replacing the sep pad well in advance of the meter counts....

[Iommanxman]

Thanks. My only concern is that they are getting around 10,000 DF feeds for each pad. Surely this can't be right? Something needs to be modified me thinks....

I will order the pad for the 2022 and try that. It looks similar. Anything is worth a try.

Thanks again.

This is the case, in our eyes it may be wrong, but Canon has done this before, B1/K1 dadf's... just order the sep pads and keep a quantity of them onhand. At first sign of multifeed,, replace it. It does seem strange that they would go away from the feeder on the 4570, as this one was decent.

[Iommanxman]

OK. Canon have come back with an official point of view.

The IR3245 series of machine has a product life of 2 million copies with a maximum monthly out put of 75k.

Right now get this. The DADF-U1 which is fitted to the IR3245 has a product life of 500,000 passes. Which is a maximum monthly throughput of 8,000 scans. What the HELL???? Canon really need to get their act together.

I too am having consistent issues w/ dadf u1-yesterday i tried a sep pad from ir 2022- call back in today! Has anybody tried to modify spring tension-was a field solution for the b1? Any suggestions would be very welcome-thanks!

[Iommanxman]

I have tried stretching the spring to increase spring tension but this made no difference. The surface of the sep pad is too smooth to grip the paper as in the other models which has a textured finish on the pad. Any idea's would be great.

[mrfixit51]

been there, done that...

I have tried stretching the spring to increase spring tension but this made no difference..

I can echo this, I have even tried 2 springs stacked together, this was on a iR2022, and this did not resolve the problem. Maybe a "skin transplant" from another sep pad, like the pebbly grey surface one, may give better results.
