Hex Print Mode; Power On State; Paper Jam Detection - IBM 6400 Setup Manual

You might want to use UNIDIRECTIONAL when printing bar codes, high
quality text and graphics, or other printing that requires precise vertical
alignment.
Although enabling this feature reduces print speed, it enhances the vertical
alignment of dots and produces cleaner, sharper bar codes and text.
BIDIRECTIONAL (the default) will print all data in both directions of
the shuttle sweep. This choice produces higher printing speed.
UNIDIRECTIONAL will print all data in only one direction of the
shuttle sweep. This choice produces higher print quality.

Hex Print Mode

A hex code printout (or hex dump) translates all incoming data to
hexadecimal equivalents. A hex dump lists each ASCII data character
received from the host computer, together with its corresponding two-digit
hexadecimal code. Hex dumps can be used to troubleshoot some types of
printer data reception problems.
Refer to page 6–9 to obtain a hex code printout.
NOTE: Printing in Hex Mode may alter print attributes set at the operator

Power On State

This parameter allows you to configure the printer to power on in the
READY or NOT READY mode.

Paper Jam Detection

This parameter determines whether or not paper jam detection is active.
When set to ENABLE (the default), paper jams are detected and when set to
DISABLE, paper jam checking is disabled to prevent false errors.
When paper jam detection is disabled, the printer does not monitor
paper motion. If a paper jam occurs, the printer ignores the condition
and continues to print, possibly causing severe damage to the printer.
