Problem Solution Can't deactivate paper-out Computer systems that monitor printer sensor with either DIP switch cable pin 12 ignore both ESC 8 and the 1-4 or ESC 8 setting of switch 1-4. These systems stop the printing when no paper is in contact with the paper-end detector (a small switch located behind the platen). Certain printer cables are designed to overcome this problem, or you can use a longer page as a backing sheet. Beeper Error Warnings When the Apex80's beeper sounds, it usually indicates that the printer is out of paper. The beeper can also be sounded by any program that sends the ASCII code 7 and by certain error conditions in the printer itself. If the printer beeps and stops printing when it is not out of paper, turn the printer off and check to see that the paper is loaded correctly. If the paper is loaded correctly, turn the printer back on and try to print again. If the printer beeps and does not print again, take it to a qualified service person. Data Dump Mode The Apex80 has a special feature that makes it easy for experienced printer users to find the causes of problems. Called the data dump mode, it gives a printout of exactly what codes reach the printer. To turn on this mode, turn on the printer while holding down both the FORM FEED and LINE FEED buttons. The printer responds by printing the words "Data Dump Mode." Then, when you run a program, either an application program or one you have written in any programming language, the Apex80 prints one or more lines. Each line has three parts: the line number (four digits), the hexadecimal codes (up to 16 numbers), and the guide section (16 characters at the end of each line except the last).

Problem
Solution
Can’t deactivate paper-out
Computer systems that monitor printer
sensor with either DIP switch cable pin 12 ignore both ESC 8 and the
1-4 or ESC 8
setting of switch 1-4. These systems stop
the printing when no paper is in contact
with the paper-end detector (a small
switch located behind the platen). Certain
printer cables are designed to overcome
this problem, or you can use a longer
page as a backing sheet.
Beeper Error Warnings
When the Apex80’s beeper sounds, it usually indicates that the
printer is out of paper. The beeper can also be sounded by any
program that sends the ASCII code 7 and by certain error conditions
in the printer itself.
If the printer beeps and stops printing when it is not out of paper,
turn the printer off and check to see that the paper is loaded correctly.
If the paper is loaded correctly, turn the printer back on and try to
print again. If the printer beeps and does not print again, take it to a
qualified service person.
Data Dump Mode
The Apex80 has a special feature that makes it easy for experienced
printer users to find the causes of problems. Called the data dump
mode, it gives a printout of exactly what codes reach the printer.
To turn on this mode, turn on the printer while holding down both
the
FORM FEED
and
LINE FEED
buttons. The printer responds by
printing the words “Data Dump Mode.” Then, when you run a
program, either an application program or one you have written in any
programming language, the Apex80 prints one or more lines. Each line
has three parts: the line number (four digits), the hexadecimal codes
(up to 16 numbers), and the guide section (16 characters at the end of
each line except the last).
