EPSON Stylus Pro 10000/10000CF Revision B
Operating Principles Printer Mechanism Components 64
PF motor Left guide frame
+42V
+5V
DC motor
PF roller is revolved via the belt slowing-
down gear
At the time of stopping, holds it with +5V
The revolution of the motor is controlled
(with superheating inhibition) the C362DRV
board on the basis of the encoder signal.
2.2.2
PF encoder
Left side PF roller
bracket
+5V Linear encoder
The band of the loop scale that was stuck to
the slowing-down gear is detected.
Generating the signal of 360LPI with, the
C362DRV board the revolution of the motor
is controlled.
2.2.2
Form adsorption (Suction) fan
(3 pieces) Main frame central
inside
+28V Blow fan
Inhaling air from the hole of the sub platen
the form causes to be stuck. (decided speed
revolution)
The inside of the sub platen is divided to 3
pieces corresponding to the fan.
2.2.2
Shutter motor (Suction control
motor)
I/S frame +28V Stepping motor
It slides paper guide L2 with the cam that
was established within paper guide L.
The slide quantity (the adsorption power) is
controlled with 20 stages on the basis of the
kind and location etc. of the form.
2.2.2
Shutter home sensor I/S frame +5V
Reflection style
photo interrupter
The home position of the shutter control is
detected with the sensor lever of the slide
device. Making the home position the adsorption
power 100% the shutter motor actuation
quantity is controlled.
2.2.2
P-FRONT sensor Paper guide L +5V
Reflection style
photo interrupter
The top of the form is detected. (Reading
the voltage value with the A/D converter on
the C362DRV board.) Using for the detection of the form
registration and form jam at the time of the
supplying paper.
2.2.2
P-REAR sensor Under paper guide U +5V
Reflection style
photo interrupter
The end is detected after the form. (Reading
the voltage value with the A/D converter on
the C362DRV board.) Using for the calculation of the presence (the
paper end) and biggest printing range of the
form.
2.2.2
P-THICK sensor
CR guide rail right
side
+5V
Reflection style
photo interrupter
The thickness of the form is detected with 2
stages.
0.6 or less mm: thin paper
0.7 or more mm: the cardboard
The slide motor control (the paper gap
adjustment)
2.2.2
Paper set lever sensor Lever bracket +5V
Reflection style
photo interrupter Condition of the paper set lever sensor
(locking/release) is detected
Detecting the paper set lever position. 2.2.2
Lever locking solenoid Left guide frame +28V Linear solenoid
Paper set lever is not able to move from
locking condition
Avoiding to operate the lever during printing. 2.2.2
Pump motor I/S frame +42V Stepping motor
It discharges the compressed air to 6 ink
cartridges
the carriage is locked at the time of motor
actuation.
Necessary ink pressure is produced to supply
the ink to the sub tank of the printer head.
