ERROR CODE and TROUBLESHOOTING
8 - 163
34 Is a certain color in the printed image turned to
black solid?
Abnormal
Abnormality in the main high-voltage
transformer corresponding to the color or
abnormality in the laser optical unit.
Replace one of 4 main high-voltage
transformers which possibly contains
abnormality, and also the one possibly normal.
Then print the same test pattern.
If the color which turned into black solid
changes along with the replacement of the
main high-voltage transformer, this main
highvoltage transformer is defined as
abnormal.
If the color which turned into black solid does
not change, check if the harness between the
LGC board and the main high-voltage
transformer is broken or if the power is
sufficiently supplied to the main charger
(breaking of the high-voltage harness or
connection defect). If no problem is found,
check the laser optical unit.
