The chassis consists of the following parts:
! The cam wheel. The cam wheel pulls the printhead assembly down
tight on the platen just before printing starts. The cam wheel is belt-
driven by a motor.
! The keypad and display. The keypad and display are used to enter
operator responses and to display instructions for the operator. For
use of the keypad and display, refer to the "Using the Keypad and
Display" paragraph of this section.
! Power switch, power cord receptacle, and parallel printer connector.
These are located on the left side. The power cord is inserted in the
power cord receptacle. The printer connector is used to connect the
GERBER EDGE to the GRAPHIX ADVANTAGE.
! The power supply. The power supply is a universal, auto-ranging
power supply capable of operating from 60 to 132 volts, or 180 to
264 volts, on 50 to 60 Hz.
The cover interlock sensor. The cover interlock sensor prevents
!
GERBER EDGE operation if the cover is not completely closed. It
is located in the top of the right side cover.
! The printhead down sensor. The printhead down sensor reads
when the printhead is contacting the platen. If this sensor is not
activated, the GERBER EDGE will not operate.
! The cam home sensor. The cam home sensor indicates to the
microprocessor when the printhead assembly can be manually raised
or lowered.
