Epson 188 - Manual (Page 67)

67 • Troubleshooting
Problem____________________________________________
There are dots missing in my printouts (typically, tops and /or
bottom of characters missing).
Solution
The head gap may not be set correctly. Try moving the Head Gap
Lever (
1 ) to a lower setting.
If that doesn’t help, the printhead may be damaged; call for
service.
Problem____________________________________________
The ALARM light is flashing.
Solution
Try turning the printer off, then back on again. If the light still blinks,
call for service.
Problem____________________________________________
The Print Quality and Character Pitch keys on the front panel don't
work.
Solution
The Operator Panel Function in the printer menu can be used to
disable these buttons (Limited Function). If the printer is part of a
customized system or if it is used by a number of people, the
system manager may have used this option to make sure the
printer is always set properly.
Check with your system manager before changing any menu
settings.
