A microswitch for each ink cartridge connected in series
and mounted on the ink cartridge detection plate at the
back of the right front cover that holds the ink
cartridges. A metal contact on the back of the ink
cartridge makes contact with the microswitch when the
ink cartridge is inserted. This tells the machine whether
the ink cartridge is inserted or inserted correctly.
A "smart" reflective sensor mounted at the back of the
ink collection tank. Detects when the ink collection tank
is almost full and alerts the operator that the ink
collection tank needs to be replaced.
Mounted above the front guide rail. Monitors the
positions of the ink level lever of each ink tank. The
vacuum created inside the ink tanks as ink is consumed
gradually draws the base of the spring-loaded arms in
against the sides of the tank. Drawing the base closer
to the side of the tank forces the tip of the arm out. The
ink level sensor detects the position of the tip every
time it passes through the gap of the sensor.
An interrupt sensor mounted in the maintenance unit
that controls the operation of the maintenance motor in
the print head cleaning cycle. At the beginning of the
cleaning cycle, a feeler leaves the gap of this sensor
and switches the motor on. At the end of the cleaning
cycle the feeler rotates into the gap, switches the
sensor off. This switches the motor off and the caps and
wiper remain down at the home position.
