I've been fighting this jam for a couple weeks now. The customer has had the machine for about a year now and everything has been great. Now its jamming with the CPFD2_S2 code (cassette 2 transport detection) and DPFD2_S4 (DPFD2 remaining jam). One call, it jammed for me every 6 pages or so from tray 2 and some of the time making a rubbing sound. Not a broken gear sound but a muffled version then immediately a jam. They say it jams out of tray 2 and 4 for sure, they dont use tray 3 much, but no jams out of tray 1. My thought process was, if tray 1 really works then the problem must be tray 2 transport or below. Most times, I go out and replace something, test with no jams, and get a call back a few days later. I've replaced the tray 2 paper feed unit with no change. I haven't seen it jam the last couple calls at all, but the machine jam log says it has been.
Over the past 2 weeks, I've also replaced the turnaround unit, the paper stop unit, and the paper feed drive pack. They are still having the jams. I see a bulletin on Sharp's website TB-259MFP-TB-259 gear pulley.PDF, but it looks as if it's referring to the transport guide below tray 2 and if so, a paper fed from tray 2 would not use those feed tires at all. The sensor works as normal in the Sim sensor check. Any suggestions or similar experiences would be appreciated.
