Troubleshooting Using the ERROR LED
You can learn the cause of a failure by the pattern of ERROR LED flashes. The following table
shows problems and solutions to repair the printer. Numbers in the "Solutions" column indicate
the order to use to check the problem. If you cannot determine the cause of the problem after
checking all the solutions listed, go back to the flowchart given earlier in this chapter.
Table1-1 Error causes and solutions
Type of Error and ERROR LED Pattern Explanation
Solutions
(Listed in order you should use to check printer.)
Autocutter error Autocutter error has
been detected.
1. Check the autocutter for paper jams.
(See page 1-18.)
2. Check the paper cutter motor sub assembly (See
page 1-9.) If the motor is shorted, replace it along
with the main board.
3. Try installing a new main circuit board unit to see if
the printer is fixed. (See page 2-30.)
If the printer works now, refer to the section "Test
Points on the Main Circuit Board Unit" (page 1-11) to
analyze the area where the failure occurred.
