If the print density is set to a darker level, printing speed may be reduced.
If the print density is set to a darker level, paper dust accumulates on the print head and
print may be faint. For information on how to clean the thermal head, see "Cleaning the
Thermal Head" on page 59.
For good print quality, set the print density, depending on the original paper number.
(See "Paper Specifications" on page 25.)
Depending on print conditions, such as print duty, print head temperature, and data
transmission speed, print speed is automatically adjusted, which may cause white lines
due to intermittent print (the motor sometimes stops). To avoid this, keep the print speed
constant by setting it lower, or set the transmission speed higher for the serial interface.
(See "Transmission Speed (DIP Switches 3/4)" on page 38.)
For good print quality, set the print speed, depending on the original paper number. (See
"Paper Specifications" on page 25.)
