I have just put a rear board from an 840 with the rom & memory into my 840 machine, it prints all the graphics and pictures, but it will not do it double sided as requested. i thought all the phasers were capable of double sided printing once the upgrade board was installed. Any ideas on how to get it to double ssided print??
Also i keep getting a jam where the paper enters the two silver rollers at the front. (the slot where you insert card for cleaning when you have a jam) can any one shed any light on the concern, and what i nedd to do to fix it
