Switch 1-5 controls the paper-end detector. When it is ON, the detector is inactive, causing printing to continue even when the printer is out of paper. When it is OFF, the printer stops when the end of the paper passes the paper-end detector. See Paper Out Sensor in Chapter 6. Switch 1-6 selects the character set. When it is OFF, the standard character set is used, when it is ON, the alternate character set is used. See Appendix A for listings of both character sets. Notice that the alternate character set has some control codes between 137 and 152 (decimal). If a software program prints a character instead of performing a printer function, such as a line feed, try selecting the alternate character set. Switch Z-7 and 1-8 select the baud rate as shown in Table D-2. Table D-2 Many software programs require a baud rate of 1200, but a higher baud rate may increase the speed of other programs. The software documentation or experimentation should be your guide to the best baud rate for each program. Switch 2-1 controls the printing of zeroes. When it is ON, the zeroes are slashed (0); when it is OFF they are not. Switch 2-2 is not used. It must remain OFF. Switch 2-3 controls line feeds. When it is ON, the LX-90 adds an automatic line feed to each carriage return; when it is OFF it does not. If your printing has an extra space between lines, turn the switch OFF. If all the lines of your printing are on top of each other, turn the switch ON. Switch 2-4 enables the beeper to sound when it is OFF; when it is ON, the beeper cannot sound. D-3

1-5 controls the paper-end detector. When it is ON, the detec-
tor is inactive, causing printing to continue even when the printer is
out of paper. When it is OFF, the printer stops when the end of the
paper passes the paper-end detector. See Paper Out Sensor in Chapter

Switch
1-6
selects the character set. When it is OFF, the standard char-
acter set is used, when it is ON, the alternate character set is used. See
Appendix A for listings of both character sets. Notice that the alter-
nate character set has some control codes between
137
and
152
(deci-
mal). If a software program prints a character instead of performing a
printer function, such as a line feed, try selecting the alternate charac-
ter set.
Switch
Z-7
and
1-8 select the baud rate as shown in Table D-2.
Table D-2
Many software programs require a baud rate of 1200, but a higher
baud rate may increase the speed of other programs. The software
documentation or experimentation should be your guide to the best
baud rate for each program.
Switch
2-1 controls the printing of zeroes. When it is ON, the zeroes
are slashed (0); when it is OFF they are not.
Switch
2-2 is not used. It must remain OFF.
Switch
2-3 controls line feeds. When it is ON, the LX-90 adds an auto-
matic line feed to each carriage return; when it is OFF it does not. If
your printing has an extra space between lines, turn the switch OFF. If
all the lines of your printing are on top of each other, turn the switch
ON.
Switch
2-4
enables the beeper to sound when it is OFF; when it is ON,
the beeper cannot sound.
