Replace the IH Power supply, it will solve your problem... Page 71 Item 5 from the parts manual.

E004-0103 The IH power supply is faulty/the IH control mechanism is faulty. After correcting the fault, be sure to reset the error. (COPIER>FUNCTION>CLEAR>ERR)
The IH current is faulty. (no current) - Check the connector for any fault in connection. - Replace the fixing heater power supply. - Replace the DC controller PCB.

This going to get expensive, could be any of the following the IH coil unit or IH Power supply unit. This series of machine uses a magnetic field to produce heat for the fusing process the process of fusing the toner to the paper, any way the code you have is stating the IH pwr sup or coil unit are not talking to the copier cpu. It could also be a relay board between the cpu fuser system, worse case the image control board. I would go with fuser power supply. Just my humble opinion.

Hello,

Code

C3B08

Description

IH input voltage error • While the IH heater was ON, input power was at the high voltage detection value or over for more than the predetermined period of time. • While the IH heater was ON, input voltage was at the low power detection value or under for more than the predetermined period of time

Causes

• IH coil unit (IHC) • IH power supply (IHPU) • Noise filter (NF1) • Printer control board (PRCB)

Remedy

1 Check the connection of the fusing unit. 2 Check the fusing unit, IHC, IHPU, NF1 and PRCB for proper connection and correct or change as necessary. 3 Check the marketing area of the fusing unit. If the marketing area is incorrect, replace the fusing unit for proper marketing area. 4 Check the marketing area of IHPU. If the marketing area is incorrect, replace IHPU for proper marketing area. 5 Replace IHC 6 Replace IHPU 7 Replace PRCB 8 Replace NF1

Hi how are you this is jack ...([email protected])..
Dear follow the procedure
[C440] Fuser abnormality after abnormality judment.

When this code not cleat 08-400 then check these all thengs..
1.Check the thermistors
(1) Check if the connectors are disconnected.
(2) Check if the main and edge thermistors are in contact with the surface of the fuser roller properly?
(3) Check if the harnesses of the main and edge thermistors are open circuited.

2. Check the IH board and IH coil

(1) Check if the IH coil is broken.
(2) Check if the connector of the IH coil is disconnected.
(3) Check if the thermostat is blown.
(4) Check if the connectors on the IH board are disconnected (AC input connector and LGC I/F connector
CN455/456).
(5) Check if the IH board or the switching power supply unit are abnormal.
• Replace the IH control board.

3. Check the LGC board
(1) Check if the connectors CN316 are disconnected.
(2) Check if the conductor pattern on the LGC board is short circuited or open circuited.
(3) Replace the LGC board.
please vote me.
Thanks
Best Regards,

This error is a fixing unit heating fault.

Possibly a blown heater element, faulty thermistor, blown thermal fuse, or maybe a bad power supply.

You will need a service technician to fix this
