• Abnormality in the main high-

to the color or abnormality in the
LED head.

transformers which possibly
contains abnormality with 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 high-
voltage transformer is defined as
abnormal.

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
