Dingo,

Check the TC spring is in place correctly. PG section 3, item 18. Same for both Tiger & Jupiter series.

The problem of restarting during a jam condition, blank pages, jamming in general and trouble code E7-90, are all associated with that spring not located correctly or missing. There is a static buildup (no ground) on the PS paper guide A.

[DINGO]

Wazza thanks, I'll check again.

[DINGO]

I'm out of luck, i chek all, and the copier gives me, E7-90, same paper jams, and continues restart.

If you're sure the TC spring is intact in the PS unit, check the grounding of the machine.

Your trouble code, jam conditions & restarting is always associated with that spring. Its gotta be mate!

maybe even try another PS unit.

[DINGO]

I suspect a bad ground at the office, but I'm confused because I have more ar-m450n in the same office and no codes.??
i will see, thanks

[DINGO]

No luck, I tried everything, and the problem persists.
paper jam, and after the copier restart and loses all work.

well.........

Have you replaced the PS unit?

Everything I've ever seen or known regarding this issue was always to do with the PS Unit & spring.

Just throwing ideas into the ring now.......
Move the machine to a different location/power lead in the room.
Make sure firmware is up-to-date.
Replace/Format the HDD.


Or.....

PCU flashrom is corrupt. Replace it.
This one is a long shot, but there are mentions of it regarding other E7-90 problems. Doubt they are related, but I have seen MX color machines throw up 'Main Program Error' messages & restarts every few weeks, eventually traced fault to PCU flashrom as well.

wazza,
I already did the following:
ps roller unit checked careful, not changed, hdd was formatted, firmware was up-to-date, and changed the power lead to.
