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?

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

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.
