TA-6501i with a Mailbox Tower MT-730

Re: TA-6501i with a Mailbox Tower MT-730

I went back to the machine and the had 8 J-7800 and J-7810 codes. I cleaned the one-way gears on the rear of the tower and the shafts. I cleaned and inspected the bushings. I even checked the motor to see if it was slipping. I had them test the mailbox again and it ran flawless, printing to each tray. Then they printed a large document that looked like someone was making copies with the ADF open and the copies had a large black border around the image. This is what was jamming the mailbox. I had them print the same document to Tray A and B and it did not jam. I tried to attach the image but it wouldn't upload.

Thanks spankycivic for the suggestion but my tightwad boss won't go for it.

I disagree that the document with large black borders was causing the mailbox jam. Once the image is printed with large black areas and does not cause a jam in the machine itself and it processes to trays a or b it points back to the vertical drive section for the MB. Once the page is printed and passed off to the finisher it does not matter how much black area there is, to the finisher it is just a piece of paper. You said you had looked at the rear of the MB, how about the bushing on the "front" side where the paddle sensor is at the bottom of the MB? I have had to replace several bushings in the mailbox front side, upper and lower, that have become contaminated slowing down the vertical drive that have thrown the timing off that have several million pages processed to the mailboxes.

Typically yes, the border will stick/curl/jam in the fuser. But I have seen heavy fill jam in a bridge unit once. Almost as if the rollers couldn't grip. Ran plain paper all day.
