Checking Result Treatment
Error clearance 1 Have you cleared the fuser error in the
Special Operation Mode?
Yes Wait until the Fuser Unit is
enough cooled down.
Then select the Special
Operation Mode and clear
the concerning error.
Wires 2 Are wires among Lamp (H1), Solid State
Relay (SSR1) and Thermistors (TH1 &
TH2) connected properly?
No Connect them properly.
Lamp (H1) 3 Unplug the machine, and then check the
resistance of Lamp (H1) with the multi-
meter.
Is it 15k ohm or lower?
No Replace the Lamp.
Thermistors
(TH1 & TH2)
4 Select the Information Mode, and then
check the temperature of fuser detected
by Thermistors (TH1 & TH2).
Item No. : 00 (Fuser temperature 1)
01 (Fuser temperature 2)
Is each temperature normal?
No Replace the concerning
Thermistor.
DC Power Supply
(DCP1)
or Fuse
5 Confirm that the machine is turned on,
and then check the voltage of the orange
line (J220-4, 220-5, 220-6).
Is it 24V?
No Replace the DC Power
Supply if there is no problem
with the wires.
Confirm that the machine is turned off,
and then check whether or not each
Fuse is broken.
Is any Fuse broken?
Yes Replace the Fuse.
Relay (RY1) 6 Select the Operation Check Mode, and
then change the signal of the following
signal to “H”.
Device Code : 22 (Fuser Relay)
And check the resistance between the
following points.
Between RY1-2 and RY1-4
Between RY1-6 and RY1-8
Is the each resistance almost 0 ohm?
No Replace the Relay.
