Strange problem with Ricoh mp7500

As Slimslob mentioned here before, you must do a PM;
replace what needs to be replaced at these counter.
Then you can troubleshoot further if the PM did not solved the problem.

I think is stop for ID check, And I thought maybe there was a problem with the grounding that was my next thing I wanted to check

Just checked Grounding with UNI METER everything is ok with ground, The problem is it doesn't do that consistently, today is a happy 5000 day series in series without any problem, but tomorrow is not known

To continue working I must reset it with 107 off and on.

Check SP 5875-001. If it is set to 0 it will cause this. Change it to 1 and the service code will be displayed.

If this occurs on mornings when you switch on the copier after rains days or weekends, the problem is humidity inside drum, a invisible layer is formed on drum by paper chemicals, toner and heat around the drum zone (don´t forget clean all filters clogged ) . Invisible layer remains humidity on drum and extend dehumidify time causing hundreds blur copies even until hours after turn on the equipment . I suggest as Konman said time ago: " Finish car polish. Polish the drum" .
Also , you can "reduce" this problem in the future by setting sp mode 3-903-001 Drum Rotation Time Extension Mode (B140/B246 Series) to " 1 " then 3-903-002 Drum rotation Time 120~600 sec.
Good luck

It's possible there's a chance that the transfer belt may either be in need of replacing or some other issue affecting transfer.
