Need some printer help

[sparky1_2007]

Hey guys, my mom has a Xerox C3545 printer at her work, and the control unit/system that drives the touch screen and stuff isn't working properly, and i was wondering if anyone here knows the exact terminology i should be using to search for to find the part that i need.

the peice that im talking about is the acctual system that hangs off the back of the printer.

if anyone could give me some help, i'd greatly appreciate it.

You should find the actual service manual for the printer, and they usually contain the parts list. You will then have the actual part name/number for the unit.
