C/earing the buffer: On Line and Style/Pitch switches
When DIP switch 2-l is ON, the printer stores received data in a large
memory buffer. This creates a problem when you want to abandon a printing
job and restart: the printer may be holding much more data in its buffer
than it has actually printed, and this unprinted data must be cleared out
before restarting. Turning power off is one way to clear the buffer, but there
is another way:
1.
2.
3.
4.
5.
Halt the printing program on the computer. If printing stops imme-
diately, the buffer is clear and the rest of this procedure is unnecessary.
If printing does not stop, continue as follows:
Press the On Line switch to set the printer off-line. Printing will now
stop, but there may be data remaining in the buffer.
Press the On line switch and hold it down.
Press the Style/Pitch switch and hold it down. You will hear a beep tone
signaling that the buffer has been cleared. If you hold down these
switches in about three seconds, you will hear three beep tones signaling
that the printer has been reinitialized.
Release these switches, make any necessary control panel settings, then
set the printer back on-line.
It is essential to halt the printing program on the computer before you
go off-line. Otherwise, when you go back on-line the computer will start
sending data again and the printer will continue printing, with missing data
where the buffer was cleared.
