Use a multimeter. Make sure it is set to dc volts. If it has a voltage scale, set it to the 20 volt scale.

Power up your card in the computer only for a few seconds, while you take the reading. You don't want to make your card's heatsink too hot without the fan going.

When it's powered up, hold a multimeter's probes on the fan's pin header pins(one on each pin), be carefull not to short the two pins together.
The meter will give you the voltage reading.

If you get a positive voltage reading, the red probe will be on the positive pin.
If you get a negative voltage reading, the black probe will be the positive pin.

Hp color laser jet 4600 57.40 error


57 indicates a printer fan error has occurred

the .4 points to the formatter fan (F1) is bad.

Connector J1004. Voltage should be 24 VDC between pins 1 & 3.

If it is, then replace the fan, if it isn't, replace the DC Controller PCB.

Check the voltage at connector J1 on the Sorter Controller pcb. 24V is supplied through the controller board and can be measured on J1 pin 2. This voltage goes to the Door Switch (MSW3) and returns on J1 pin 1. If 24V is not present on pin 2, it is possible that the Sorter Controller is bad.

I got an error message 57.01 on my printer. how do i solve this problem


A printer fan error has occurred.(Delivery fan)

J1033 - Measure pins 4 and 6 for delivery fan

1. Turn the printer off then on.
2. Reconnect the connector J1004 on the DC controller PCB.
3. Immediately after starting the print operation, measure the voltage between the appropriate pins on the connector. If the voltage changes from 0 V to 24 V, replace the affected fan.

Cannon-3300 Copier Error code E000-0000 rectify the problem


E000 0000
The reading of the main thermistor does not reach 30°C 1 sec after the main
power switch is turned on. Or, it does not reach 70°C 2 sec thereafter.

Main cause:
The fixing film unit is faulty. The main thermistor has an open circuit. The
fixing heater has an open circuit. The main power supply PCB is faulty. The
DC controller PCB is faulty.

Caution:
To reset the error, execute the following in service mode:
COPIER>FUNCTION>CLEAR>ERR.

Action:
1. Connector
Is the connector of the fixing assembly connected?
a. main power supply PCB (J8) <-> relay connector <-> heater
b. DC controller PCB (J320) <-> relay connector <-> thermistor
NO: Connect the connector.

2. Fixing film unit (thermistor)
Check the interval between pin 1 and pin 2 and between pin 3 and pin 4 of
the connectosr (4-pin) of the thermistor for electrical continuity. Is it ¥W
(open)?
YES: The heater has an open circuit, or the thermal switch is open. Replace
the fixing film unit.

4. Main power supply PCB, DC controller PCB.
Press the Start key. Is the drive voltage of the heater supplied by the connector
J8 of the main power supply PCB?
Main heater: between J8-1 (FSR1) and J8-5 (FSR COM)
Sub heater: between J8-3 (FSR2) and J8-5 (FSR COM)
YES: The heater drive power supply is faulty. Replace the main power
supply PCB.
NO: The thermistor control mechanism is faulty. Replace the DC controller
PCB.

I HAVE A CANON IR 3300 MACHINE I HAVE ERROR E00000-000


WHAT: Either the main thermistor doesn't attain 30?C 1 second after the power switch is activated or it doesn't attain 70?C 2 seconds thereafter.

WHY: It has a faulty fixing film unit, lack of connectivity with the main thermistor, lack of connectivity with the fixing heater, a faulty main power supply PCB, or the DC controller PCB is faulty.

NOTE: You can reset the error by performing the following in service mode: COPIER>FUNCTION>CLEAR>ERR.

CONNECTOR FIX: Make sure that the connector of the fixing assembly is seated.
A. main power supply PCB (J8) relay connector heater
B. DC controller PCB (J320) relay connector thermistor

FIXING FILM UNIT (THERMISTOR) FIX: With a multimeter, check the interval between pin 1 & pin 2 & between pin 3 & pin 4 of the connector (4-pin) of the thermistor for electrical continuity. A result of ?? means that the circuit is open (lack of connectivity). Resolve this by replacing the fixing film unit.

MAIN POWER SUPPLY PCB, DC CONTROLLER PCB FIX: Press the Start key. If the drive voltage of the heater is supplied by the connector J8 of the main power supply PCB, then the main power supply PCB should be replaced. If not, then the thermistor control mechanism is faulty & the DC controller PCB should be replaced. Use the following to ascertain this:
Main heater: between J8-1 (FSR1) & J8-5 (FSR COM)
Sub heater: between J8-3 (FSR2) & J8-5 (FSR COM)

Extra wire /fan 3pin hole 1wire where to plug in X 2 fans


If your cpu fan has a 4 pin connector & your mb has a 3 pin you can still use it. Just leave one pin exposed. The extra pin is for a speed control sensor that not all mb's support. The chassis fan has a different connector on the board marked "cha fan". This one is a 3 pin connector. Most of the asus boards have 1 of these. If you wish to run more than one you can either buy a "y" adapter that allows you to connect 2 fans to 1, you could use an extra 4 pin molex to power an extra fan but that would give you no control over the fan, or you could buy a fan controller and hook all your extra fans to it. Hope this helps & please take a moment to rate my solution fixya. Thanks.
