Trying again
After you have checked the troubleshooting list, turn the printer
OFF then back ON again to register any new settings of DIP switches.
Then try printing your test file again. If the file still doesn’t print prop-
erly, work through the problems again, changing the settings as neces-
sary.
If a further attempt at printing your test file is unsuccessful, contact
your Epson dealer.
Beeper Error Warnings
When the beeper on the LQ sounds, it usually indicates that the
printer is out of paper. The beeper can also be sounded by a program
that sends 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 if 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.
Hex Dump Mode
The LQ has a special feature that makes it easy for experienced
printer users to find the causes of problems. The hexadecimal (hex)
dump mode gives a printout of exactly what codes reach the printer.
Enter this mode by turning on the power switch on the left side of
the printer while holding down the FORM FEED and LINE FEED but-
tons at the same time. Then, when you run a program, either an appli-
cations program or one you have written in any programming
language, the LQ prints one or more lines.
Each line has two parts: the hexadecimal codes (up to 16 numbers),
and the guide section (16 characters at the end of each line except the
last). The hexadecimal numbers are the codes received by the printer,
and the guide section helps you find a certain place in the list of codes.
Each character in the guide section corresponds to one of the codes.
If the code is for a printable character, that character is printed. If the
code is for a non-printable character, such as the ESCape code or the
code for a line feed or carriage return, a dot is printed.
