Lines of dots are missing in the printout.
Cause What to do
The print head is damaged. Print the current settings in the default
settings mode and check the pin
condition. See “Changing default
settings” on page 94 to see how to print
them.
If only one pin is broken, other pins can
compensate for it. See “Broken pin
compensation” on page 85 for details.
If more than two pins are broken, stop
printing and contact your dealer to have
the print head replaced.

Never replace the print head yourself; you may damage the printer. Also,
other parts of the printer must be checked when the print head is replaced.

code to each carriage return. See
“Changing default settings” on page 94.
The printout has extra blank lines between lines of text.
