1052 with a J-9203 jam

[kenpio]

Have a our old, well not too old just well used, has almost 35milion on it. Right now it cannot duplex. Has that 9203 jam code. Have had it apart and cleaned the guides. Checked all the sensors in the path, PS35, 45, 47, 48 and 64. They all check out in the I/O mode. We have replace the turn guide plate and the rollers. It seems to be getting caught it the PS45 sensor hole. The middle of the page seems to be sort of folded in the middle and in that hole. We were able to run one page through the machine and it went. When two went through, it jammed on the first page. We have ordered the ADU board, the ADU reversal roller and the bottom plate guide assy. We are hoping for the best. Just wondering from the vast pool of experience hereif anyone has seen this?

Thanks
KEN

Check the drive belt on the back of the duplexor Part figure 11 A1TT211400 Drive Belt /1 309L

On high mileage machines this belt will lose some ribs and cause duplex jams. I replace the belt and pulleys (A0G6813200 Conveyance Pulley /2) as a kit.

Just want to thank WJ!!! We took out the ADU unit and took a look at that belt. It was missing about an inch worth of teeth. So I had order those parts on Tuesday and they should be in tomorrow. We have the ADU unit out of the machine now. Never would have thought about a belt missing teeth!!

Thanks

Thanks for the feedback. We've got a couple of 1250P's with escalating copy counts. I'm sure I'll get my chance to try this fix. =^..^=

good afternoon to all, I saw a post pro 1052 referring to the jam j-9203, I have a pro951 machine that has presented this jam, but only in size A4, in the A4R it works perfectly, I checked that it makes some printed, but immediately for when the paper is being turned on the ADU, I checked that it passes the rollers, as if losing between the roller and the turn of the paper, does anyone have any idea? she's with 3million prints

Good afternoon to all gentlemen, the problem reported by me was resolved, I did a general cleaning of the ADU and all the rollers, sensors, redid all the wiring connections, and the equipment started working again, thank you all
