iR1510 close platen/cover problem

[DadO]

Hy tech, greetings!

Copy count is 5040 K. Paper has jammed at fusing and costumer tryed to pull it out, little peace stayed inside. When they turned machine on again message was shown " PLATEN/COVER IS OPEN CLOSE PLATEN/COVER".

I don't know did anyone tempered whit machine but they say this is how it happened. Friend whit lot more of exp. on those machines say someone "forgot to plug the connector"

I replaced fusing film and lower roller in fusing unit since both where destroyed. I seek for unplugged connector on the back on the boards and at the power unit but couldn't find any.
i did "clear all" in error at service mode and didn't help

I ask for an suggestion and help for this issue
Machine is at my service shop

THANK U ALL AHEAD FELLOW TECHS !
