5.1 Setting of DIP Switch No. 1
The DIP switch No. 1 consists of the following 8 pins.
A summary of the functions of the respective DIP switch pins and their preset condi-
tions at the time of shipment are shown in Table 2.
Table 2 Functions and Conditions of DIP Switch No. 1
(1) SW1-1: Setting this pin to the ON position will cause the line spacing to be au-
tomatically set at 1/8 inch per line upon power application.
(2) SW1-2: Setting this pin to the ON position will cause the form length per page
to be set at 12 inches. The form length per page becomes 11 inches
when this pin is set to the OFF position.
(3) SW1-3 & 1-4: Combined use of these two pins permits selection of the number
of columns per line as shown in Table 3.
(4) SW1-5: Never set this pin to the OFF position. Always leave it in the ON posi-
tion.
(5) SW1-6: This pin is used to activate or inactivate the paper end detector. When
this pin is turned on, the paper end detecting function becomes invalid upon
power application and the Printer is allowed to operate even if it is out of paper.
With the Printer in this state, input of control code "ESC 9" will permit the paper
end detector to be activated again.
(6) SW1-7: This pin is used to select an international character set in conjunction
with DIP switch No. 2 upon power application.
(7) SW1 -8: When this switch is set to the OFF position, SLCT IN signal is not fixed
internally, thus permitting the Printer to be controlled from a host computer.
NOTE: This signal line is wired ORed with the pin No. 36 of the interface con-
nector. Therefore, to control the signal level with the pin No. 36 of the in-
terface connector from the external CPU through TTL, etc., leave this DIP
switch pin to the OFF position.
