Chapter 6—Setting Up the Printer
Print Speed
The print speed is variable between 100 and 200 mm/sec. for printers
fi tted with an 8 dots/mm (203.2 dpi) printhead and between 100 and
150 mm/sec. for printers with an optional 11.81 dots/mm (300 dpi)
printhead. Generally, the lower the speed, the better the printout qual-
ity. This is especially true when printing bar codes with the bars running
across the media path (“ladder style”), when printing on demanding face
materials, and when printing at low ambient temperatures. The default
setting is 100 mm/sec. (approximately 4 inches/sec.).
The combination of a large media roll (>152 mm/6 inches
diameter) and/or narrow media width in combination with
high print speed (> 150 mm/6 inches per sec.) could cause
jerks in the media feed. Such jerks will compress text and
spoil the readability of ladder-style bar codes placed close
to the front edge of the label. In case of batch printing,
only the fi rst label in the batch will be affected. Negative
startadjust values tend to increase the jerks.
• If the media roll is larger than 152 mm (6 inches), do
not use a print speed > 150 mm/sec.
• If a negative start adjust is used, do not use a print speed
> 125 mm/sec.
• Narrow media width may require further restrictions on
print speed.
• Avoid placing text and ladder-style bar codes close to the
front edge of labels.
LSS Test
The function on the label stop sensor (LSS) can be tested automatically
or manually as decribed in Chapter 12 “Adjustments.”
LTS (Label Taken Sensor)
The sensitivity of the LTS can be tested and adjusted as described in
Chapter 12 “Adjustments.”
