2.2.3 Sensors and Safety Interlocks
The condition of each of the interlock sensors described below, as well as some others whose operation is
invisible to the operator, is reported to the host computer. How the host software deals with these messages
may be different for a given host. Consult the documentation supplied with the
RIP
for more information.
2.2.3.1 Door interlock
The door interlock switch arrangement is made up of two (for redundancy) magnetic switches mounted in
the cover of the imagesetter. These switches are activated by two magnets in the Base Plate of the machine
when the door is closed. These switches must be satisfied in order for the imagesetter to turn on the laser.
2.2.3.2 Out of Paper Sensor (
OOPS
)
The
OOPS
is located in the film supply compartment. When film is properly loaded into the machine, the
sensor is satisfied. When the film runs out or is removed the sensor reports this to the imagesetter which
inhibits any further imaging and displays an
message on the display.
2.2.3.3 Out of Cassette Switch (
OOCS
)
The
OOCS
is a magnetic switch located inside the imagesetter cabinet that senses the presence of a magnet
located in the Output Cassette. If the Output Cassette is not mounted to the front of the cabinet, the
imagesetter will not allow a film feed from the front end. Film feeds from the imagesetter front panel are
not inhibited. A
message will appear on the control panel.
