512 LINE PRINTER OPERATION
The 512 Printer combines the printer and its controller in one cabinet. Paper supplies in
front of the machine pass upward between the printer gate on the front door and the print
head in the cabinet and emerge at the back. Operator manual controls on the back duplicate
four switches on the front to facilitate removing paper.
Front panel controls in Figure D-3 include indicator lights for the controller as well as
the manual operation switches.
