bypass tray shows legal when 11x17 loaded on 8 series

[Synthohol]

Finally got a weird one to run by my fellow colleagues.
I have a c458 that when you put 11x17 on try it shows as 8.5x14 (legal) but letter shows up fine.
Once the outer length actuator is down it goes to legal unless I open the width guides to 12"

I have already tried the bypass width min max adjust. It passes max width but min says NG unless I open the guides up like a quarter inch.
I even replaced the bypass tray with new and same issue.
What's worse is even if I open the guides to have it display 11x17 you can copy to it but a print job errors and asks for 11x17 which is already displayed.
Media type is correct and matches driver settings.

Real stumped here, anyone run into this?

Also it's using an older N2 FW to avoid the 'fiery not connected" nightmare.
I hesitate to apply current FW because it loses connection to the fiery frequently.
Hope someone has a solution.

Thanks all.

This is weird one and I have no clue but I will look into my soft switch table for any related settings.
Stupid question but does FW level matches print driver version?

It has a fiery controller.
But I like the way you think.

This started all of a suddon, it was not an issue out of the box.

I even initialized it, put movie data back on and reloaded the FW. No change.
I thought it may have been the rheostat in the tray but when the brand new bypass unit was replaced nothing changed a bit.

Did you look at the adjustment steps in the manual?? There is a new way of doing bypass adjustment for the last couple of series. You are supposed to put paper in tray and then
hit adjustment start.

LOL, just saw that 10 min ago, 110mmx297mm for the min/max.
WTF KM!!
ill try tomorrow.

Yeah, they pulled a fast one on us but it's been this way since way back on the C253 Series (BUT make sure and check each model's service manual because the min/max distance isn't always the same). I kept having issues on a 4e machine, doing the adjustment the way I always had for over 2 decades, guides to max and min position for max and min adjustment, because that makes sense. Finally looked in the book and discovered we'd been doing it wrong for many years.

Re: bypass tray shows legal when 11x17 loaded on 8 series

we assumed it was the same as the ADF min/max!!

So did we but it's not actually min/max of the guides position, either. Most now have a specific position for those as well. They keep screwing up common sense.

Wouldn't a different bypass with a different pot sensor work though?

Not until the calibration is done properly. I first came across this on the bizhub 1052. The original size calibration mode on the copier asks for one size but really means another. Once you run the calibration correctly it will all straighten out.

DF detects LTR-R original size as LTR, after changing DF controller. A mistake is displayed in service mode > Machine > ADF Adjustment > ADF Original Size Adjustment. The correct width adjustment sizes are LTR and STMT-R. Instead of using LTR-R like it asks, use LTR original width.

I love our European sizes. Almost all A4 and a very few A3.........

This is a good thing to know!
I would have probably started swapping boards, dissecting wiring harnesses and start looking for "special" FW, to solve this if I was Synthohol (difference is that he is smart enough to ask for help). At least KM is forcing us to keep us on our toes.

Service Manual... What is that?

Service Manual... What is that?[/QUOTE]


It's that thing we never look at until we've disassembled a machine down to its component parts... and can't quite figure out how to put it back together again!!

Re: bypass tray shows legal when 11x17 loaded on 8 series

Wow, great info mo0651! ...I just looked up that adjustment.......I also would have addressed an issue like this with parts or maybe swapped out the whole bypass unit.

Manual Bypass Tray Width Adj Procedure:

1. Call the Service Mode to the screen.
2. Touch [Machine] -> [Manual Bypass Tray Width Adj].
6. Touch [Min. Width.].
7. Load the bypass tray with paper having a width of 110 mm.
8. Press the Start key and check that the results are [OK].
* Make the adjustment again if the results are [NG].

Those paper sizes you load in the bypass tray are not USA though. So for future reference , Conversion of 297mm and 110mm below:

A4

297mm x 210mm

11.7inch x 8.3inch

DL (Cseries envelope)

110mm x 220mm

4.33 x 8.66

Service Manual... What is that?

It may be just me but...as we(techs) almost always blame customers that they didn't read/follow the f. manuals it's perplexing for me to do the same.
