Part of the printout is missing, or dots are missing in random 
positions.
Cause What to do
The ribbon has too much 
slack, the ribbon has come 
loose, or the ribbon cartridge 
is not installed properly.
Remove any slack in the ribbon by 
turning the ribbon-tightening knob, or 
reinstall the ribbon cartridge as 
described in Chapter 1.
The ribbon is worn out. Replace the ribbon cartridge as 
described in Chapter 1.

The print head is damaged. Stop printing and contact your dealer 
to have the print head replaced.

Caution:
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.
All the text is printed on the same line.
Cause What to do
No line feed command is 
sent at the end of each line of 
text.
Turn on the auto line feed setting 
using the printer’s default-setting 
mode or the EPSON Remote! utility so 
that the printer automatically adds a 
line feed code to each carriage return. 
See “About Your Printer’s Default 
Settings” in Chapter 5 or “Using the 
EPSON Remote! Utility” in Chapter 4.
