Re: SF7850 can't reset h4
Hey Frank,sorry I missed this thread,I use to work on a lot of these machines.You are going crazy with these switches but why cant you test each individual key to see if it works?
enter 44 and hit clear,if it clears the key works, press 10,see if zero works,if it works hit clear again,all will go,next enter 22,then press interupt,if it allows you to make a copy "in interupt mode" you have test all keys and all is well.
if all keys are known good,do the sequence fast and do it 5 or 6 times in a row,the 7800 was sometimes a pain to get into service.
If you still have issues Frank try to short out the battery,or pull the battery if it is not soldered,I forgot it has been too long.\
I have backdoor codes somewhere,if you need anything let me know
