Canon IR 8070 copier K1N finisher problem

[landspeeder]

Was working on a IR8070 copier, replaced the laser, and now the copier goes to a suspend mode when trying to print etc. It sounds like its going to print but just suspends itself. If I seperate the finisher, K1N type, and unplug it from the copier, the copier works perfectly. With the finisher plugged in, there is led's lite up on the main board in the back of the finisher, one is blinking, if I open the finisher door the copier detects that its open. When powereing up the copier the finisher doesnt do a startup routine, motor turns, trays move or maybe its not supposed too...I am not sure of that.

So any one have a idea? Thanks

The first thing I would try would be doing a DC-CON CLR and see if it properly boots up after that. After that maybe try reloading the firmware. Are you getting any error codes?

No error codes at all....just the flashing error light and like I say soon as you unplug the finisher the copier works perfect...can it be a board problem in the finisher and does the finisher have a power up routine when started

thks

Yes it could be a finisher controller board problem. Normally when the machine starts up the finisher does "jog" the trays and cycles the rollers.

I'm ok with that...wouldn't be the first time I ordered a board and it didn't fix the problem! Thanks to Canon tech support that is!!!
