It detects whether the pressure by the pump
+5V Photo interrupter
motor is in a prescription value.
The lock lever location of ink pump Assy is
+5V Photo interrupter
detected.
The pressure that is loading it to 6 ink
+28V Linear solenoid
cartridges is canceled.
The valve that supplies ink from the sub
+28V Linear solenoid
tanks of 6 ink cartridges to print head.
The type of the presence and color of the
+5V Board
ink cartridge are identified.
The make and break of I/C holder cover is
+5V Microswitch
detected.
The ink pack configuration (the presence of
+5V Microswitch
the ink) inside the ink cartridge is detected.
It forces the cap device to the head end and
+42V Stepping motor
stick (the carriage locks).
The home position (the sticking location) of
+5V Photo interrupter
the cap device is detected.
Absorbing ink from the print head it
+42V Stepping motor
discharges it to the waste ink tank.
Laser optical (5mw) for dot detection is
+10V Laser diode
output.
+5V D/A12 bit converter The light from the laser diode is detected.

Printer Mechanism Components
Explanation Function / control / others
The C362DRV board makes the pump motor
the ON when the pressure becomes below a
prescription value.
When locks the carriage with the lever during
the pump motor detection and the pressure
reach the prescription value the locking is
canceled.
At the time of the power supply OFF at the
time of and the ink end detection canceling
the pressure the ink leakage is inhibited.
When the surface of a liquid sensor that is in
the sub tank of a printer head becomes below
a prescription value opening the valve the ink
is delivered.
The wrong installation inhibition of the ink
cartridge.
halting the ink supply and printing actuation
in the time that I/C holder cover is opening.
In the case that this sensor detected, LCD
displays "Ink low".
It causes to stick the cap to the print head on
the basis of the cap sensor, and do the head
protection of the head cleaning.
The pump motor actuation (ink suction) is
enabled with the home position detection.
At the time of the head cleaning actuation and
the early period fill of the ink it drives.
While discharging the ink from the nozzle of
the dot head and moving the print head, judge
whether dot missing is occurred or not (Laser
light the attainment to optical department).
