Warning: CPU Fan is LOCKED -- Lexmark X500n printer

This is an error message we get on a consistent basis now on our laser-jet printer. #1 - is this as simple as changing out a CPU fan. #2 - how do I do this?

Tim
Exact same problem.  No fan appears to be available.  Lexmark says it requires a total motherboard replacement.  Printer is 14 months old, 2 months out of warranty.

    Error message = Warning: CPU Fan Locked.


    When I open up the printer, the CPU fan is starting and stopping.  A simple replacement will likely solve the problem, but Lexmark doesn't have a part number for just the fan.  They claim an entire motherboard replacement is necessary.

    Lexmark x502n, Model# 7100-110.  Thank you!

    We are having the exact same problem. Bought the unit in Nov of 07 and have had the error message for about 2 weeks. We have had our local IT guy look at it and he said it will probably last for quite a while. To replace the motherboard would be about as much as purchasing a new printer. Glad we are outside the warranty by 2 months!

    Low Profile Copper CPU Fan For P4 (Socket 478) w/Blower (JACA-44C) $71.00
    .. is NOT the right fan, not even close (wrong voltage)
    the Lexmark X500n, X502n needs a 24V DC 5x5x1cm 3-wire fan

    The most commonly available fans of the correct size are 12VDC.

I fixed this in 12 minutes. I took the fan out, lubed it up with a high-tech petroleum based lube and freed up the fan. Reinstalled and no more error message. We ordered a new one so when this fails, we'll be ready. It seems that moisture got into the axle and corroded it and caused it to lock up.

Wow!  After several hours searching I found the fan connectors to buy (since the fan comes with bare wires from cypower.com).  The connector is made by JST America and can be purchased from Digikey at www.digikey.com
Part number 455-1126-ND for the housing 
Part number 455-2148-1-ND for the pins

(You have to buy at least 10 housings and 100 pins but together they cost about $2.50 total)

You can buy the crimper too, but they are $1,300.  I just use a needle nose pliers.

Good luck

I had an old celeron processor 12VDC fan, cutted some plastic, tied some wires with a 6VDC adaptor, made a whole for the screw, and I have circulating air again.

CPU fan locked


Wow, after hours of searching I found the right connectors for the fan since it comes with bare wires when ordered from cypower.com.  (The fan to order is a 24v DC Y.S. Tech FD245010MB.)  The connectors are from JST America and can be ordered from www.digikey.com. 

Part 455-1126-ND (housing that takes pins spaced 2mm apart)
Part 455-2148-1-ND (pins)

You have to order at least 10 housings and 100 pins but all of that costs about $2.50.

You can also order the crimp tool but that costs $1,300.  I'll just use a needle nose pliers.

Good luck!

My Lexmark 500n has a warning message [ WARNING: CPU Fan is Locked ]what does that mean?Seems to print fine but the message is ;( Anybody know what I should do?


Might be some foreign debris stopping the cpu fan from running and cooling the cpu.

I wouldn't leave this problem for long since a fried cpu will mean the end of your printer

Warning: CPU Fan is Locked!


You have a fan that is not working.
Just be happy that is isn't the photoconductor.
What kind of computer is it?
If a fan isnt working it is not the end of the world,... Front fans go all the time and are basically useless anyway.
If it is hampering our ability to print lemme know and I will delve further into this.
I will need the make and model of the computer/printer.
