Self-Test; Table 1 Interface Signals In Paper-Out Status - Epson MX-80F/T Operation Manual

Table 1
When the Printer falls into paper-out status, the buzzer sounds intermittently
for 30 seconds to alert the operator. After the buzzer stops, paper advancement
can be performed by depressing the LF switch.
After setting new paper in the Printer, depress the ON LINE switch so that the
Printer may resume operation. There is another way to start the Printer again
when it falls into paper-out status. Set new paper in the Printer, and turn the
POWER switch off and on again, or apply the m signal.
In this case, however, all previously established data such as TAB, line spacing,
etc. are erased.

Self-Test

4.
The MX-80 F/T has a self-test (self-diagnostic) function to check the following.
(1) Print head operation and printing quality
(2) Operation of the printer mechanisms (motor, cartridge ribbon mechanism,
belt. etc.)
The self-test function is pre-programmed and can be performed by turning the
POWER switch on while depressing the LF switch. All characters provided by
the internal software are printed out on the paper by this operation.
NOTES:
1. The self-test function cannot be performed when the printer is out of
paper.
2. To check all interface logic including the interface connector, proceed
as follows:
(a) Connect ACKNLG signal pin No. 10 to STROBE signal pin No. 1 with
a lead wire.
(b) Turn the DIP switch 2-3 (on the control circuit board) ON to effect
auto-line feed.
