†Platen Gap home position flag

The PG HP flag is located on the PG gear on the right side of the carriage. This gear connects with the PG gear assembly when the carriage is in the home position and the Pump motor is active. The PG origin sensor is a reflective sensor which detects when this flag is in the PG origin position.

†Carriage home position flag

The CR HP flag is located on the right side of the carriage. This flag cuts off the signal in the CR origin sensor. The CR origin sensor is a photo sensor which detects when the carriage is in the home position.

†Cutter solenoid

The solenoid is attached to the carriage on the opposite side of the home position (in the cutter housing) and it drives the cutter toward the paper. The spring drives the cutter back away from the paper. Also, the cutter solenoid is used to release the carriage lock.

In order to cut roll paper evenly, the following method is used:

1)The cutter cuts from the left of center (when facing the printout) to the left edge.

2)The cutter cuts from several centimeters inside the right edge to the right edge.

3)The cutter cuts the remaining uncut portion, in the center, from the right side to the left.

†Cutter height guide

An important point is the cutter height guide which slides up and down. Its function is to stop the cutter guide at the correct height, which is determined at the factory. Due to this added feature, no carriage cover height adjustment is necessary, unlike the EPSON Stylus Pro 9000. Normally, you should not loosen or remove the screw that secures the cutter height guide.
