Using the Data Dump Mode
The data dump mode is a special feature that makes it easy for
experienced users to identify the cause of communication problems
between the printer and application programs. The data dump
mode gives a printout of the codes reaching the printer.
To use the data dump mode, follow
these
steps:
1. Make sure that the printer is loaded with either single-sheet or
continuous paper.
2. If the printer is on, turn it off; then hold down the
FORM FEED
and
LINE FEED
buttons at the same time you turn on the printer.
3. Run any program that causes the printer to print (either an
application program or one in
any
programming language).
Your printer prints out all the codes
sent
to the printer, as shown
below. (To print the last line, you must take the printer off line.)

On the left side of the printout all the codes are printed in
hexadecimal format. On
the
right side of the printout all
printable characters are printed, and others, such as control
codes, are represented by dots.
4. To turn off the data dump mode press
ON LINE
to take the printer
off line. Then turn off the printer. (You can also cancel the data
dump mode by sending an INIT signal from the computer.)
By reading the characters printed in the text field on the right side of
the data dump printout (see step 3) or the printout of hex codes, you
can
check which codes are being sent to the printer.
