Not necessary information about resistors, any more. I found on the board a Zener diode (5V) and I calibrated the two resistors to obtain on it that 5V. I mounted the repaired power supply and our machine works perfectly.

No, we do not have a summa dealer around... I tried to repair the damaged power supply device. I found a 2.0A ULTRA-FAST RECTIFIER in short-circuit and two resistors presenting signs of over heating. I replaced the rectifier and the power supply works. I tested with (1.5 A) and without consumer...

I did as I said and the fuse was immediately burned (with a small flame)... So I need to check the power supply. If somebody is able to recommend a site where such a device is sold, this will be much appreciated. Thanks in advance!

Thank you! I was not looking for such an appearance... The fuse is not OK. It is burned but it is very improbable to be burned without o short-circuit after it... I intend to solder a very thing wire just to see if it is immediately burned (or not...) and identify the power supply. If I can see...

Our Summa D120 cannot be powered ON. The cable is OK, but something connected with the cutter itself looks to be. So I am looking for its fuse and I cannot see it. I was expecting to be somewhere ease to see it but I do not see any. I replaced the plastic cover on the power connector side and no...

Finally I solved the head! I unclogged it completely... I will briefly try to explain what I did, but just for people daring to do it. Firstly the method is good to be applied just for a head not offering perfect nozzle check but the appearance of consecutive checks is different. I mean if one...

What about this nice price for head...? DF-49684

Firstly sorry for the late reply... The cleaning station worked very well. A lot of ink was coming to the waste ink tank. I cut an old had and I could find a net inside the black side which I am sure it is clogged in ours. Theoretically this side can be dismantled and cleaned passing cleaning...

I'm still using it but without that part of the nozzles... I mean I transform (in Photoshop) CMYK in CMY with a specific color profile (testing a lot) and it is not any difference between original K and the one made from the other three colors. Of course the ink consumption for black side of the...

Yes, we can. That machine head has been changed three years before. But we have other machines in good condition fully loaded and why not keeping it like spare and using it in order to explore its possibilities? It is not loaded and we can afford playing with it in let's say didactic way. We...

Very clever... Usually when you want to loose time it's good you just sleep. We will not be informed about your tiredness. I tried thinking and finding solutions based on logic. That process is difficult indeed and not accessible to anyone...

I fount a way to take out the air. There is an option in Self-Diagnosis Mode to close and open the valve when you need...

We use such a machine since 2011 and it worked well. Last year we faced a problem regarding black side of the head and it was obviously for everybody that the had is gone. But I found a way to transform any CMYK layout in CMY, using a specific color profile and the layout transformation is not...

We print on ValueJet 1614E since 2011. We used to have some clogged nozzles even we changed a printing head. We usually understand when and how is necessary to clean the head. Now something strange is happening... One rectangle of black ink nozzle check (the second one) started to miss lines. In...

On a Mutoh ValueJet 1614E machine the nozzle check for one side of black ink was not perfect. I had a clogged nozzle from some time and I tried to unclog it. I pulled some cleaning liquid through the nozzles. Gentle, without pushing hard until all the jets were clean and parallel. I mounted the...
