The paper supply may be too far from the printer, or not
aligned with the front or rear tractor. Also, some obstacle may
be in the way of the paper or something may be on top of the
paper supply. If you use the rear tractor, make sure that your
printed documents do not interfere with the rear paper supply.
See Chapter 2 for instructions on the proper placement of the
paper supply.
If you are using labels, you must take extra paper handling
precautions. See the section in Chapter 2 on using labels.
Hex Dump Mode

problems between the printer and application programs. In
hex dump mode, all codes received by the printer are printed.
1.
To enter hex dump mode, hold down both the
LF/FF
and
TEAR OFF
buttons while you turn on the printer.
2.
Next, run a software program (even one you have written in
any programming language) and send a print job to the
printer. Your printer prints all the codes it receives in
hexadecimal format as shown in the sample below:
