EPSON Stylus Pro 10000/10000CF Revision B
Operating Principles Printer Mechanism Components 65
Pressure sensor Ink pump Assy +5V Photo interrupter
It detects whether the pressure by the pump
motor is in a prescription value.
The C362DRV board makes the pump motor
the ON when the pressure becomes below a
prescription value.
2.2.5
Carriage locking sensor Ink pump Assy +5V Photo interrupter
The lock lever location of ink pump Assy is
detected.
When locks the carriage with the lever during
the pump motor detection and the pressure
reach the prescription value the locking is
canceled.
2.2.5
Air valve solenoid Ink pump Assy +28V Linear solenoid
The pressure that is loading it to 6 ink
cartridges 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.
2.2.5
Pump valve solenoid Ink holder +28V Linear solenoid
The valve that supplies ink from the sub
tanks of 6 ink cartridges to print head.
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.
2.2.5
Cartridge sensor Ink cartridge +5V Board
The type of the presence and color of the
ink cartridge are identified. The wrong installation inhibition of the ink
cartridge.
2.2.6
I/C holder cover switch
On the right of I/C
frame
+5V Microswitch
The make and break of I/C holder cover is
detected. halting the ink supply and printing actuation
in the time that I/C holder cover is opening.
2.2.6
Ink end sensor Ink cartridge +5V Microswitch
The ink pack configuration (the presence of
the ink) inside the ink cartridge is detected. In the case that this sensor detected, LCD
displays "Ink low".
2.2.6
Cap motor Cleaning unit inside +42V Stepping motor
It forces the cap device to the head end and
stick (the carriage locks).
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.
2.2.3
Cap sensor Cleaning unit +5V Photo interrupter
The home position (the sticking location) of
the cap device is detected. The pump motor actuation (ink suction) is
enabled with the home position detection.
2.2.3
Pump motor Cleaning unit +42V Stepping motor
Absorbing ink from the print head it
discharges it to the waste ink tank. At the time of the head cleaning actuation and
the early period fill of the ink it drives.
2.2.3
Laser luminescence
department
Dot missing detector +10V Laser diode
Laser optical (5mw) for dot detection is
output. 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).
2.2.4
Laser optical department Dot missing detector +5V D/A12 bit converter The light from the laser diode is detected. 2.2.4
