[CQ] Xerox C70 PQ issue with error codes not in eDoc

[Mr_FixOK]

Hello All,

I have a C70 at a customer site that is dropping PQ on the pages intermittently. It seems okay if they print/copy in B&W mode only. If printing or copying in color, sometimes the back 2/3rds to 3/4ths of the page is faded out. This machine has a fairly new 2nd BTR. I just replaced the ITB belt when I checked the color first BTR release mechanism for action. After replacement of the ITB belt the machine came up and printed test print 19 at 60% coverage fine for the K only, K in color mode, M and Y then started failing again when printing C. I rebooted the device and when it came back up it printed color fine for the customer at the time but failed again shortly thereafter. I've tried to attach some PDF scans of the issue. The first one is K in K only mode and K in color mode. The second are CMY showing the issue. All these are test print 19 at 60% coverage and 600 dot. I would appreciate any insight that you folks have.

Have you checked out tip number 1401352?

Same sort of image problem as you seem to have. Caused by 2nd btr retract sensor flag being damaged so 2nd btr retracts just fine but because of sensor flag being broken, it drops too soon.

Whatever though, I'd say this is a 2ndBTR issue and regardless of how new, I'd be replacing that first.

Yep I did see that article and tried the 2nd BTR to no avail. There is no damage to the flag as in the article either. Also, this only affects prints/copies in color. B&W mode prints and transfers fine. I just tried a stop print and checked the belt and the image is not complete on the belt so that leads me to believe that the issue is with image formation or 1st transfer. I can see the 1st BTR roller end from the front with the door cheated and the 1st BTR is not retracted all the time. It might be retracting at the wrong time or maybe there is a problem with the 1st BTR HVPS? Probably try a whole ITB next.

Thanks for your time and help too! I sincerely appreciate your assistance.

Hello all,

Just a follow up that this issue was resolved by replacing the bottom connector on the back of the fuser drawer. There was the slightest deformation of 5 of the pins and this seemed to be causing intermittent connection issues. Thanks for all the help!
