The print density can be set also to a customized value. The initial setting of the customized
value is “Depends on the DIP switch settings.” If the customized value is changed, the
value set with the customized value is enabled. (See
"Setting the Memory Switches" on
page 43
.)
Depending on print conditions such as print duty, print head temperature, or 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 (See
"Setting the Memory Switches" on page 43
.), or set the
transmission speed higher in case of the serial interface. (See
"Transmission speed (DIP
switch 1-7/1-8)" on page 36
.)
