Chapter 4 Printer Control Menu

Unidirectional

The Unidirectional feature affects both print quality and printing speed. By setting this feature, you can configure the printer to print in both directions of the shuttle sweep (bidirectional), or to print in one direction only (unidirectional).

You might want to enable this feature 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. Choices include the following:

•Disable. The default. The printer will print all data in both directions of the shuttle sweep (bidirectional printing). This choice produces higher printing speed.

•Enable. The printer will print all data in only one direction of the shuttle sweep (unidirectional printing). This choice produces higher print quality.

PMD (Paper Motion Detection) Fault

•Enable. If a paper jam occurs, an audible alarm beeps, the LCD displays the message, “CLEAR PAPER JAM,” and the printer stops printing.

•Disable. You should disable PMD only if special paper requires it.

Caution	Once PMD is disabled, paper motion is not monitored. If a paper jam
	occurs, the printer ignores the condition and continues to print,
	which can cause severe damage to the printer.

Open Platen @ BOF (Bottom of Form)

Some special forms have perforation areas that are too thick to pass through the print station. This parameter, when enabled, opens and closes the platen when the perforations move across the platen. When enabling this parameter, you must set the forms length to match the physical distance between perforations.

Slow Paper Slew

This parameter affects the speed at which paper advances into the stacking area of the printer. The speed may be slowed down by enabling this feature.

• Disable. The default. The printer will slew and stack paper at maximum speed.

• Enable. Causes the paper to stack at a slower pace. This ensures that certain forms will stack more neatly.
