Data Dump Mode

Data dump mode is a special feature that allows experienced users

to find the cause of communication problems between

the

printer

and computer. In data dump mode, the printer produces an exact

printout of the codes it receives.

To use data dump mode, follow these steps:

1. Make sure paper is loaded and the printer is off.

2. Hold down both the

LF/FF

and

LOAD/EJECT

buttons while you

turn on the printer.

3. Next, run either an application program or a program you have

written in any programming language. Your printer prints all

the codes it receives, as

shown

below.

4. To turn off data dump mode, press

the PAUSE

button to stop

printing and then turn

the

printer off.

Look at the data dump shown in step 3. On the left side of the
printout, all the codes are printed in hexadecimal format. On the
right side of the printout, the same codes appear as printable
characters or, if they are nonprintable codes-such as control
codes-they appear as dots.

By looking at either the characters printed in the text field or the
hex codes, you can see exactly what codes are being sent to the
printer.
