5.2.7 Option detection mechanism
This printer has the mechanism that automatically detects whether the tractor unit is installed as a push tractor or
a pull tractor.
Installing the tractor unit at the rear of the printer pushes down the feeler and raises shield plate A as shown
below. The photosensor on the bottom of the carriage detects this condition and determines that the push tractor
is mounted.
