Epson LQ-670 Problems and Solutions

3. Open a software program and send a print job to the printer.

Your printer prints all the codes it receives in hexadecimal

format.

By comparing the characters printed in the right column

with the printout of the hexadecimal codes, you can chec k

the codes being received by the printer. If characters are

printable, they appear in the right column as ASCII

characters. Nonprintable codes, such as control codes, are

represented by dots.

4. To turn off hex dump mode, press the PAUSE button, eject

the printed page(s), and then turn off the printer.
