This is a flatbed printer A3+, that can print on any material (except dark material). This printer has label "YG Flatbed printer 1000 A3+", but on the Web I saw that it also have some other labels (I suppose that each of its merchants invented new name for this type of flatbed printer). I knew that, this flatbed printer is based on Epson Stylus Photo 1290. I bought it from a Chinese company, but unfortunately or fortunately the company no longer exists.
I had big problems with this flatbed printer, and I even replaced all except the control board of the flatbed printer, but in the end I have reported the same problem with the printer. It remains only to replace the control board of the flatbed printer, but it's very hard to find this control board, especially if the control board has no label (and actually I do not know who are the manufacturer of the control board). If anyone knows someone who has such a flatbed printer, or if anyone knows some good maintenance/technician of these printers, please can You connect me with him. Here I post an image of the control board, so if anyone has some advice, feel free to tell me.
A brief description of the problem:
The problem occurs in DC motor that controls the movement of table (that simulate paper), the output (from the control board) that is used to power the DC motor has a power that vary a lot and has a large deviation during the printing, so printed images are spread out up to 5x more than the original image.
If anyone might know what the problem is, again feel free to tell me.
Also, here are something that I try to print, and on the end what my printer had printed up.
Sorry for long post...
