Initialization
The SQ-2000
is
initialized
(i.e., set to a fixed set of conditions) in
the following cases:
l When you turn the power switch on.
l (When you use a parallel interface) If the INIT signal is re-
ceived from the host computer, causing pin 31 of the parallel
interface to become LOW.
l When you give the <ESC>@ software command.
The initialization sequence proceeds as follows (except when
using the software command):
1. All interface signals are reset.
2. The input buffer is cleared.
3. The ON LINE indicator goes on and the SQ-2000 waits to
receive data.
4. Printer parameters are initialized to the default settings.
5. The default values of the DIP switches are set.
The <ESC> @ sequence only performs the last two opera-
tions. The DIP switch values are set to the current values even if
the power has not been switched off.
