1 PF Encoder Detects the PF Scale patterns to control the paper feeding (operation of the PF Motor).
2 Roller Release HP Sensor
Detects the position (Contact/Separate status) of the driven roller.
3 Driven Roller Release Motor Assy
Drives the driven roller. A DC motor with an encoder scale mounted on it is employed.
4 Driven Roller Release Motor Encoder
Detects patterns of the scale attached on the motor to control the rotation of the Driven Roller Release Motor Assy.
5 PE Sensor A reflective photo interrupter to detect the presence of paper.
6 Paper Thickness Sensor Detects the thickness of paper being inserted into the printer.
7 Rewind Motor
Takes up the slack of the roll paper when the motor rotates normally, and rewinds the roll paper when it rotates reversely. A DC motor with an encoder scale mounted on it is employed.
8 Rewind Motor Encoder Detects patterns of the scale attached on the motor to control the rotation of the Rewind Motor.
9 PW Sensor
Detects the width of paper on the platen. It is a reflective photo interrupter and detects the difference of the amount of reflection between paper (white) and the platen (black).
10 Cutter Sensor Detects the origin position of the cutter.
11 Suction Fans
Suck paper to the platen so as to stabilize the position of paper when printing. Three fans are mounted for Epson Stylus Pro 9900/9910, and two fans for Epson Stylus Pro 7900/7910
12 Cutter Encoder Detects patterns of the scale attached on the motor to control the rotation of the Cutter Motor.
