Appendix D
Defaults and DIP Switches
This appendix lists all of the default settings and lists and explains
the settings of all the DIP switches.
Default and Initialization Settings
The T-750 can be initialized (returned to a fixed set of conditions) in
three different ways: when it is turned on, when it receives an INIT
signal at the parallel interface (pin 31 becomes LOW), and when it
receives the ESC @ command.
The following conditions are always reset:
l The print head returns to the home position.
l
Interface signals are reset, and the printer is put on line.
l The current print line is cleared.
l
Margins and vertical tab settings are cleared, line spacing is set to
l/6-inch, horizontal tabs are set at every eighth position and vertical
tab channel 0 is selected.
l
The page length and skip-over-perforation are set according to DIP
switches 2-1 and 2-3, and the top of form position is set to the
current line.
l The ROM characters are selected, and the Epson mode character
table and international character set are reset according to DIP
switches l-3 and 1-6 to 1-8.
In addition, when the printer is initialized by turning on the power
or by an INIT signal, the data buffer is cleared of all text.
ESC @ resets the typestyle to the current SelecType settings, but the
other two methods reset the typestyle according to the DIP switches.
Also, ESC @ does not check whether any DIP switches have been
altered since the printer was turned on; instead it uses the old settings.
