Need Help Summa DC 4 SX blending colors don't match and a streak in the middle of the print

[vsdesigner]

Hello,
I recently bought a Summa DC 4 SX, the seller didn't tell me that he made a scratch on the print or that the color unions don't match 100%, I'm frustrated with this purchase, the brand representatives only point to one new head, my question is: Has anyone had this problem with the union of colors? As you can see in the image, Cyan, Yellow and Magenta are acceptable, but black in the union appears a risk, I have to solve this to think about buying a new head, because I won't spend that much money, so that the color combination will be thus,

Have you tried to clean the head? Switch off the printer (very important), remove the cartridge at the position were the head can be reached from the back side, use a lint-free tissue with a little bit of alcohol and clean the print head thermo element line.

Some banding needs to be compensated with feed settings, but cleaning can help with intermediate problems.

If it is black only, it could be the ribbon too.

Hello Frank, thank you for your attention!
I've already cleaned it, but the scratches are still there, and the joining of the colors sometimes overlaps and sometimes separates

Use a a jeweler's loop and flashlight - inspect the head carefully. My geber edge( same technology) can get a spec of lint or paper and cause the same issue. Also re-seat the head cable.

Hello Jburns, thanks for the tip, i'll do this

I would recommend a linefeed calibration test. They do recommend doing this each time you change the role of vinyl.

What media do you use? This printers are very sensible according to the media you print on.

Hello Jburns, to be able to see the head would have to take it right? If yes, do you know how to do it??

Good morning,

While it does look like you need to manually align the head(the left sign will need to be adjusted so the overlap meets up correctly) if you have already cleaned the print head and are still getting that white line the runs the full width of the print, you will need to replace the print head. Our team may be able to help with the head alignment, however there isn't really a fix for a blown dot on the head if in fact that is what is going on(that's what it looks like to me in the photo).

I have attached a copy of the DC training aid document that has some information on aligning the print passes.

Please let me know if there's anything that myself or my team might be able to do to help.

Best regards,

Hello Phil,
Thank you very much for your attention, yes, I've already cleaned the head, but the risk hasn't disappeared, so I plan to buy the head, but I'm afraid to buy, and keep not aligning as passed correctly, I'll do what's in the document to see if it solves, as for the manual head alignment, can you support me?
And by the way, can you give me the document for Adjust Linefeed?

Kind regards
Vitor Santos

Hello Frank, what you are talking about is from her manual, what i got the idea in the PDF that Phil posted, is that there is one more document to adjust the LineFeed

This was almost perfect linefeed calibration, but as you can see, on the left side the print was almost perfect, but not on the right side

Seems a dead head.
Try anyway to clean the whole printer from upsidedown as it won't let any dust anywhere and also the registration marks sensor . also make sure that you clean the printhead properly i mean in it all surface.
Find another dc4-5 it be found for nothing today, cheaper than a head.
