GENERAL DESCRIPTION
Table 1-10 shows the printer select/deselect (DC1/DC3) control, including relations among ON-LINE,
SELECT-IN input, DC1/DC3,
and interface signals.

NOTES:
1. In Table 1-10, it is assumed that no ERROR status exists other than that attributable to
OFF-LINE mode.
2. Once the printer has been put in the deselected state by the DC3 code, the printer will not revert
to the selected state unless the DC1 code is input again. (In the deselected state, the printer
ignores input data until the DC1 code is received.)
3. The DC1 and DC3 codes are enabled only when the SLCT-IN signal (Input Connector Number
36 for the parallel interface unit) is HIGH and printer power is initialized.
4. If the SLCT-IN signal is LOW when the printer is initialized, DC1 /DC3 printer select/deselect
control is invalidated, and these control codes are ignored.
5. If the SLCT-IN signal is HIGH, and is not set to LOW by jumper 10 when the printer is initialized,
the printer starts from the selected (DC1) state.
