so sorry i didn't follow my gut. and now i am in it for a system card. it wont come to ready. i wanted to try a new firmware. i booted it with out the phone board, then without the toner, then disconnected a plug from below hoping it was for paper feeder. nothing other than new codes till i reconnected it back. does anyone have any much needed advice?? it was a long haul changing the board and i have left it in. i looked at one outfit i have used in the past to get a manual and nothing listed for that model. man i hate when this happens. thank you for any help, Jim
