Xcalibur 45 problem

[ceconet]

Hello good people in the forum,

lately i've been having this problem:



Started about a month ago but it was once or twice every 100-200 plates. But at this point is every plate after the first after boot.
It shows no indications that there is a problem. Every test i've run is in the norms (or atleast doesnt show any obvious problems).

I'll be gratefull for any help or advice to help fix this.

Afaik the Agfa Xcalibur uses GLV head. The banding can be caused by improper head settings (you need an experienced AGFA engineer), dirty optics (clean it) or something else malfunctioning. The problem with these lines in the right side of the plate, you may check the data cable between the RIP and machine, or the data cable inside the machine. Moreover you may check the power supply of the laser head. Why don't you call Agfa service? Isn't it faster and easier, than writing in a forum for such strong problem?
Just thinking!

Good Luck!

Hello, thanks for the reply,

we have checked all the cables but we still have the problem. The banding is only when the plate is exposed incorectly (exposure starts not at the plate edge but somewhere after(pic1 for reference)).
We bought this machine second hand and we have no contract with Agfa. In our country there is no one specialising in Agfa machines.

So any advices will be helpfull.

There is no banding on the plates. I do not see any banding in the picture. Where the idea of banding came from?

This is an Edge detect issue and not the banding. The Faulty AFIM (Autofocus Illumination Module)or noisy Machine power supply(Not the Laser Power supply) can cause this. Run the Xcalibur45 Edge Detect Stability script on unidiag . It will show you an unstable edge detect position( different calculated and original plate size) as attached file. The values on your machine might be different for different plate sizes compared to the sample picture. This for such an intermittent problem is where you have no problem with line voltage or the power supply.

Hope this will help!

Hello,

thanks for the responses.

We did a lot of calllibration and checking on all of the components.

At this point things are somewhat ok, but it still does it at about 50+- plates.

We recallibrated the AFIM and did a Xcalibur45 Edge Detect Stability test and we got all possitive results.

Is there a chance something else is causing this?

Did you replace the Power Supply?Can you send me a picture of the S-Curve to be taken from Gnu Plot?

 

[Armya Inc]

The S-curve you sent me was smooth and OK. This shows a stable AFIM. I would like you to check the S-curve graph when the edge detect problem (The one on your picture) can be seen on the plate. The curve will be fuzzy and not smooth any more. I understand this is an intermittent(not permanent) problem and hard to detect on the Gnu Plot. I suggest to change the power supply and make sure the input line voltage is stable and use proper stabilizer. Open the attached file for the power supply's picture. Hoping this will answer your question in PM.

Ceconet,

You recently sent me a PM as follows. I think, I can close this thread now.

Hello,

sorry for the long time for the reply.
Seems we had a problem with our electric instalation. But it seems we got it sorted out for now.
Really appreciate the help..........................................................................................................................Ceconet

Hi I have a Xcalibur 45S and I get an error A0303, reviewing the system got two things: One of the motor field magnets was out of alignment and was loose, so disarmed and sent for repair (replacement) since it was split. Furthermore no fixed clamps then release the printed sheet, so that we check the system air pressure. I would like your guidance on the steps I am taking, if I'm right and I can recommend further action to reboot the machine.

If you need help then you will need to write these comments step by step and understandable for someone who isn't in the site. The way you rushed through writing this it sounds like we are in your site and have seen all the steps you have taken. Secondly, it is unclear what steps you have taken.

Ok Thanks for the clarification
My problem is this: The bar drum when being returned to release plate, sometimes it do not release clamps and a jam.

 

[@gochigans]

disassemble the engine and note that one of the magnets of the field was misaligned, so I proceeded to send it for repair. I'm checking that occurs parallel to the clamps do not release plate drum

I would like to help with this error because the A0303 error listing OCT does not appear.

Thank you.

Better!
Bar Drum?????? A0303/Media Handling Failure/Drum timed out moving home during Init.

That means that the Clamps holder wouldn't release the Magnets on the plates, because the drum isn't on the right position or can't reach there. This is an Applicator Micro error.

Error 0303 could cause by clamps. Which will bring this in mind that if you had a plate jam or removed a Jammed plate prior to this error. What is the A~Z story?

 

[@gochigans]

Prints La Plancha, then turning the Droll not loose it and then damaged.
Errors: A0012 and S1064

Nice wordings. I didn't understand a word what you have said here!

But here is the translation of the errors:

A0012/Media Handling Failure/Drum timed out moving MC next to FC. The drum doesn't turn to right position within the defined time for letting the clamps to sit on the plate. Too slow drum movment or can't find the right position.

S1064 is a parameter error. Ignore it.

Without knowing what has been done prior to these error, I `d like to know:

1-Do you have these errors without plates being loaded and during the boot up sequence?
2-What is the Air pressure value on the gauge..........
3-Test Vacuum sensor with aid of the unidiag-------- Does solenoids pull in and out properly.

This issue can be resolved by an experienced service Tech. Why do not you call a REP in.
