You can either copy or scan, you cant do both at the same time.
Our machine doesnt do that... what frmware are you on?
Are you making a booklet or something maybe? Then the machine needs to know the amount of pages before it can calculate its booklet order...
Is there a way to print copies as they're being scanned. Our WorkCenter 5755 seems to scan everything before printing. Takes up a lot of time when doing large jobs.
