(17-1-1) Check of connections
Connection between PU
PCB (PRF PCB) and high-
voltage PCB
Check to see if the 13-pin FFC is properly plugged into
the HVOLT connector of the PU PCB (PRF PCB).
Also check to see if the 9-pin FFC is properly plugged
into the CN connector of the high-voltage PCB.
Search for an imperfect connection or skew insertion.
Correct the insertion
of the cord properly.
FFC interconnecting the
PU PCB (PRF PCB) and
the high-voltage PCB
Check for a wire breakage with a circuit-tester. Check
visually for peel-off of the covering.
Replace the
connector with a
normal FFC.
(17-1-2) Environmental condition
Heavy variation of
environmental condition
Check to see if the environmental condition has changed
from a low-temperature condition to a high temperature
condition in a short time.
(For example, the printer was moved from storage in a
cold region to an office environment.)
Switch on the
printer again after
acclimatizing it to the
new environmental
temperature for one
hour or so.
Before turning on
the power, touch the
sheet metal of the
controller panel on
the back and internal
sheet metals in
order to see how the
casing of the printer
is warming up.
Turn on the power
again when much
difference from the
room temperature is
no longer perceived.
