[Misc] MPC-2011 flashing red side/duplex door open & back to normal

[jsr123]

Dear All

one of MPC 2011 keeps on flashing red light within intervals on two to five minutes
for write side / duplex door open and with three seconds becoming normal again.

This keeps on heppening. If any thing printing copying or scanning in between lost
communication.

Already replaced door switch with white lever and even exit unit. Duplex door manually
checked by keep on pressing hard. Still flashing red.

Thanks

if you replace door cover switch already then look for paper sensor it thinks there is a jam will tell you same thing open cover. could be a crimp wire some where. do a input check on sensor see it changes state by itself.
