EPSON Stylus CX3500/CX3600/CX3650/CX4500/CX4600 Revision A 2.2.3.2 Carriage Home Position Detection 2.2.3.3 Sequence Used for PW Detection As in the conventional model, the Carriage Home Position is detected using the drive current of the CR Motor and the speed/position signal of the CR Encoder. The basic home position detection sequence is as described below. The PW (paper width detection) Sensor installed on the Carriage Unit bottom is used to control the printer according to various sequences.
EPSON Stylus CX3500/CX3600/CX3650/CX4500/CX4600 Revision A Item Description The drive of the PF motor is transmitted to the LD roller shaft and the PF roller through gears for the Paper loading/feeding mechanism. The Paper loading mechanism plays a role in loading a paper from the ASF unit to the PF roller. And also, the Paper feeding mechanism plays a role in feeding a paper loaded from the ASF unit.
EPSON Stylus CX3500/CX3600/CX3650/CX4500/CX4600 Revision A For your reference, the top or the end of a paper is usually detected with the PE Sensor. In case that the PE Sensor cannot detect the top of a paper in the paper loading sequence, the printer indicates the “Paper Out error”. If the PE Sensor cannot detect the end of a paper in the paper feeding sequence, the printer indicates the “Paper Jam error”. As for the details, refer to Chapter 3 “Troubleshooting”. 2.2.4.
EPSON Stylus CX3500/CX3600/CX3650/CX4500/CX4600 When the PF Motor pinion gear rotates CCW direction (right side view), the Change Lever pushes down the Clutch lever as right figure and the Clutch lock tooth is disengaged from the Clutch Gear. As the result, the LD Roller Shaft dose not rotate at all because the drive of the PF Motor is not transmitted.
EPSON Stylus CX3500/CX3600/CX3650/CX4500/CX4600 The PF Motor pinion gear rotates CCW direction (right side view), and the drive of the PF Motor is transmitted to the LD Roller Shaft through the Clutch lock tooth and the Clutch gear.
