KM-C2525E

Hi Kyo gurus

Canon tech need some advice. KM-C2525E At the first have display masage like remove cassette 1 and check paper jam.Of course there is no paper.After reseat connectors related with lift motor and
initiated 906 i got the same problem with cassette 2. Even more! When i pull out cassette 2 lift motor start to rotate and it stops when i return cassette back in.After that i got error 1010.I suspect on short circuit on pwb.Reason must be dead motor or something similar.This is i hope some known Kyocera trick.Thanks in advance!

The way I would address this is to order two lift motor assemblies and an engine PWB. Historically, when a Kyocera lift motor shorts out it takes out the motor control circuitry on the engine PWB. The typical diagnostic method is for the tech to swap the upper and lower (identical) lift motors to see if the inoperative tray port starts to work. Of course it doesn't, and the shorted motor now takes out the other motor driver circuit.

If you could know for positive which lift motor has the short, you could replace just that one and the engine PWB. But alas, If you choose wrong, you get to order another engine PWB.

It's safer just to order both lift motors and the engine PWB and replace all as a set. Be sure to swap over all EEPROMs and memory chips to your new engine PWB, and to reload both part #1 and part #2 firmware via CF card.

Expensive and fun. Enjoy! =^..^=

After i swap lift motors,rotation problem moved to cassette 1 and still have display masage "pull out cassette 1 and 2 and check for jammed paper".Two lift motor and engine PWB ordered.

Still waiting for engine pwb.At this time i still play with the machine and i got error 4100 after U21.Is this function erase some parameters which are not mentioned in manual or just sign for bad pwb?

I'm sorry to say that doing an U021 All Clear was a really bad choice. You've essentially tossed out all the image quality adjustments that made your machine make decent copies. Hopefully you printed off the Maintenance List so you can re-enter the hundreds of values now gone.

The 4100 is a beam detect error for the laser. You may have dumped the laser settings.

This is going to be one of those really memorable learning experiences. If you have the Maintenance List, you have created 4 hours of completely unnecessary work for yourself. =^..^=

make sure the side door is closed all the way. I have seen this cause a false laser code especially if there is a finisher attached to the machine. Sometimes the finisher pulls on the door and it opens slightly causing the error. Good luck

And if i don't have Maintenance List?

Thanks!

That leaves you with two options:

1) Print off the maintenance list from another functional KM-C2525E. The data will not be exactly correct, but perhaps close enough to get copies. Then you can start the arduous process of running every electronic adjustment on the machine.

2) Buy a used, working KM-C2525E and give it to the customer at a loss. Over the long run you may recover some of the cost in reusing some of the consumables from your doorstop. But in the end, without the maintenance list settings it is a doorstop.

You probably assumed that an U021 All Clear would reset to factory defaults. It does not. It zero's all values. I don't think you'll have to repeat this mistake. =^..^=

[zoraldinho]

You're right! Factory defaults not zero's all values! Who need's zero's values? I can change to zero my self if i need that! My problem is too much confident. First i'm gona fix this quick and if i stuck then i read manual.My ass!Definetely i will not repeat this mistake again!
