Denmark, Sweden, Italy, and Spain as shown in Table 5 upon power applica-
tion.
(2) SW2-3: This pin is used to fix AUTO FEED XT signal internally. (Refer to the
explanation of control code "CR" in paragraph 3.1 (1) "WHAT IS THE MX-80
TYPE II?".) This signal line is wired ORed with the pin No. 14 of the interface
connector. Therefore, to control the pin No. 14 externally through TTL, etc.,
leave this DIP switch pin to the OFF position.
(3) SW2-4: This pin is used to set the automatic skip-over perforation function.
(a) When this pin is set to the OFF position, the automatic skip-over perfora-
tion function becomes valid. By this function, the paper automatically
advances to the first line of the next page when the remaining page length
is 1 inch.
(b) When this pin is set to the ON position, the l-inch automatic skip-over
perforation function becomes invalid. However, you can activate this func-
tion programmably (described in detail later).
