Operation Manual

1.3.4 Automatic interface switching function
This printer has a function to automatically switch the interface.
With this function, when printing is not executed from either interface, printing can
be executed from either the USB or the parallel interface.
The switching cannot be performed until after the printing starts from one of the
interfaces and the buffer becomes empty after printing.
1.3.5 Detection functions with sensors
The printer detects the status of the machine with sensors, as shown below.
The home position sensor has two functions: it also operates as the purge sensor to
detect the operation of the purge unit.
The home position sensor senses the home position edge and detects the carriage
position. After the edge is detected, the carriage moves to the right a specified number
pulses to identify the home position.
Also, at the capping position, it works as a purge sensor and detects the on/off of the
purge sensor flag during cleaning operations to recognize the operation of the purge
unit.
