need help with metoform 5240 ra-4 processor

[czygeorge]

Hi all~
I got an metoform 5240 made by meteor siegen which hardly has traces on the internet. It's very big and heavy.
But which unfortunately is the heater and led of it just couldn't work. I open it up, but could find no hint inside of it. Only find two of threes fuses are gone(One missing one defective). But even when I changed it, still made nothing different.
Does anyone know something about this issue?Thank a lot!
Best regard
George

A question for you . Why did you buy it?
Planning to print large amounts of printed photos?
The purchase decision in itself has many question marks?
These old machines are always defective and have huge problems.
How can you find spare parts for this processor, especially heaters, etc.
It is very complicated and complicated, and I do not think that this forum has experts in this type of processor, I recommend searching in the forum (Minilab)
- I think your only chance is to find a technician who specializes in this kind of ancient processors in India, India used to like these processors for small photoshops.

Can you post some pictures?

 

[mshchem]

I find a lot of pictures of machines, but no instructions,. This is the first I've seen these machines. Look very heavy 62kg!
Looks like this could be used for black and white polyethylene base paper.
Looks good.

Aha! I looked up images as I was curious about this machine, I had never heard of it. Then I saw the images- it looked very familiar because I use one, sold under a different name here is the US: Beseler 16 Auto Print Processor. It is a wonderful machine, easy to maintain with dry to dry paper handling. Speed and temperature are easily adjusted with knobs- I use it for RA 4 print processing. I will dig around and see what literature I can find for it, maybe there are wiring schematics that would be helpful.

Hi~
Because I used to use jobo system. And it's very trouble because you have to wash and clean the drum every time after you process one paper. But use this dry to dry processor could make color print much convenient( And I do color print a lot).Actually the structure of paper processor is very simple. A heater,two water pumps and a motor for those gears and roller and a main circuit board to control. I guess the problem of the one I have it's the main board has some hurt, hope it could be fixed by electrician.

Dear mshchem
Sorry I tried but those photos are too big to upload. You can find some when you Google the name of this processor,metoform 5240. Yes, it's very good because you can adjust the speed and temperature of process. The instruction says what btaylor says in German. But they are not that pretty when its function has lost

Dear btaylor
Yes, they are very same. All of this machine hardly have difference in their structure. Thanks a lot for helping, hoping that could help me make it

First thing to do is open it up and inspect the roller rack closely. Examine the rubber rollers to verify if they're undamaged and supple. If one or more rollers are damaged, I would think twice about attempting to repair the electronics. If the rollers are in good condition, I'd start disassembling step by step and drafting a schematic in the process. Usually such equipment isn't insanely complicated. From there, it's a matter of troubleshooting and determining a repair strategy. It'll be a project for the more electronically inclined enthusiast though.

Maybe; do you have experience with this particular model? I know there are many old Thermaphot ACP processors still around that still work. The rollers are the Achilles' heel, but if properly stored and used, many are still fine.

Hi koraks! Nice to meet you again
The rollers work fine,and actually, that's why I bought it because I saw its rollers look very new. And I test it with photo paper,it's all good.
The Water pumps and the roller works good. I asked some of my friends here and they said those Fuji processor Always have this kind of issue when their main board has problems. And I think that's why the fuses are defective too( It's too silly that I forgot to let the seller send me test video, but trust him hundred percent).
Yes, I open the whole machine up. It's not very easy because it's too heavy! Luckily, it's very easy to do, but not like jobo atl has many tricky there which make it very hard to dissemble the machine without repair manual. And I saw the whole structure are kind of simple there, which funny is that the chain contact motor to roller gear is same to those chain used by bicycle.

I was about to buy one almost the same, I think it's Italian made as far as I remember. It was cheap and looked like new.
But I sought the advice of a man who works as a technician for laboratory machines, and he said to me: Even if it works, you should not buy it, because it no longer has spare parts, especially the heat heater, which is the biggest pest in those machines, and when it breaks, you can't find a replacement part for it.
She gave up on the idea.

Yes, that makes sense because the heater of durst printo is very common to fail. But actually The heater is just a metal part connect with power, So it could hardly go wrong in other type of this machine.

Hi all，fortunately, the machine has been fixed.
The electrician found that a capacitor was burned out. He replaced the new capacitor and fuse, and everything was repaired. Thank you very much for your help. If anyone has any questions about this, you can ask me. I'm very happy to help

 

[koraks]

Excellent, that's great! Sometimes a simple fix is all it takes

 

[mohmad khatab]

Excellent

Hi,
if you still need informations like instructional manuals pm me.

Hi Paul
I have it,Really thanks for helping!And if you need any help with this machine just tell me

Hi There, i may need some help, i newly purchased a metoform 5040, unfortunately the LED is not working anymore, but the thermostat and roller are working! Is there a way that i can test which capacitor need to be changed?.
I can post some pictures about the main core chip here. I ve changed the 4700nf capacitor also the phototransistor. But still the LED is not working. You can find me in wx: Thecameraguy for a direct chat.

Welcome to Photrio @Luki !

the LED is not working anymore, but the thermostat and roller are working! Is there a way that i can test which capacitor need to be changed?.

It's unclear/uncertain and not necessarily very likely that a failed capacitor is the cause of a LED not working anymore.
What is this LED supposed to do? When should it light up?

Photo 1 is likely part of the low-voltage logic DC power supply and some filtering on the AC side; the round object top left of the photo is a bridge rectifier; there's likely a voltage regulator just below it (the one with the heatsink). If the machine mostly works OK then this section is likely just fine.

Photo 2 is what looks like a 8051-series microcontroller to me, which is the central 'brain' of the machine. Again, if the machine works fine for the most part, this chip and its directly associated circuitry is likely OK

Photo 3 shows a 4-port NAND chip; its specific function here is unclear.

None of this is directly usable in tracking down this specific defect. What is needed is a set of electrical schematics of the machine; on that basis and your fault description it may be possible to formulate a couple of hypotheses of what might be wrong, then you can do some selective tests/measurements to eliminate these one by one.

I ve changed the 4700nf capacitor

Which one? Did it help/make a difference?

the phototransistor

Again, which one, where is it in the circuit and how does it relate to the LED?

Anyway, a schematic would be very helpful. Otherwise it'll be a matter of doing measurements around the LED and then seeing if the problem can be traced back, but lacking a schematic, it can be a lot of work and it requires some basic knowledge of electronics as well as a good deal of patience, and possibly partial disassembly of the machine so you can trace tracks also on the backside of the PCBs.
