[Error Code] error code L4 - 31

[wim]

I've recieved by power on the error code: L4 - 31.
After reading......I understood one or two paper cooling fan, and located both fans (open right door, at the top)

Also: Run sim 6-2 to check if the fans are connected.
Maybe stupid, but.....how to start the sim test programs?
I read into the technical manual: press "code mode key", then "Program key", then "*", then "clear key", then "*", then your sim program.
This is absolutely chinese for me..... (and I am dutch)

none of the keys are responding, because a error message: call technical service, code L4-31

Is somebody able to explain that to me in normal words how to reach the sim test programs??
were is the "code mode key"? item 2 in picture, see attached image
were is the "program key"
And the "* " is item 8 ??? ( see picture)
And clear is item 5 ???

thanks in advance !

Re: error code L4 - 31

Thank you so much !!!
I found it.

And also both fans are not running. I opened the back cover, and checked the HDD fan, but that one is running well.

Strange, I expected one fan dead, but two? tomorrow I'll check this, maybe a loose wire or connector.
So, I will remove the paper cooling fans tomorrow, and if they are faulty, see if they are available somewere.

Thanks again for the hints!

Re: error code L4 - 31

All the fans are the same. So if you have a parts machine you can use them.

It is not unusual for both fans (above the fuser) to fail soon one after the other, but at same time - a bit unusual. It is best to replace both at the same time if only one fails.
Your English, by the way, is better than some that are native English speakers, IMHO.

Re: error code L4 - 31

Hint:
How to reduce the noise/vibration with cooling fans :
If you want to prevent CPU cooling fans or similar fans from vibrating and creating a noise, remove the metal based sticker/label from the center of the rotory blades. The label glue becomes soft and moves the label off center creating just enough vibration and noise to reduce the life of the fan. I have proved this to many associates over the years. Those assocates complain of noisy CPU or video card fans where I have no such problems.

A tad of trivia for the serious computer gamers out there...

Re: error code L4 - 31

I don't know how much time it will buy you but those fans can be disassembled.

When you remove the round sticker there is a plastic retaining "C" ring on the motor shaft. with that removed you can slide the fan blades off, then lubricate the bearings. Mine were generating a cloud of iron oxide dust. A few drops of light oil and some manual spinning got that fan back up and running. And yes, both fans quit within 3 weeks of each other. =^..^=

Yes true, there is nothing inside those fans. I quick drop of silicone grease/oil on the brass bush an off they go again.

I'll try first to fix it with the hints given here.

Re: error code L4 - 31

Do you have a parts machine? Maybe a boneyard?

Re: error code L4 - 31

We pay less than half of that for hours so I'm it might be worth doing a little shopping around because if you consider how much time it takes to remove the parts how much time it takes to repair the fans and the fact that you'll be back in a couple weeks to do all of that over again that really will be a savings either to you or to the customer by just replacing them

Re: error code L4 - 31

I removed both fans, and looked around (type the partcode on top of the fan, 2408NL-05W-B56) and found some friendly prices: $ 32 each:
NMB-MAT 2408NL-05W-B56 Server - Square Fan 2408NL-05W-B56, T01

or $ 25,14 each:
Original Nmb 6020 2408nl-05w-b56 24v 0.09a Line Cooling Fan 2408nl-05w-b56 Online with 25.14/Piece on Linda111's Store | DHgate.com

now see if they are shipping parts to the Netherlands, and the shippingcosts.
answer hopefully tomorrow.

thanks guys for your help.
