DIY on a new printer with a cardinal error - manufacturer's instructions
Last year in September, I bought a GKtwo for work. Immediately after the first print, there were glitches on the screen. After a while, the screen would start to show glitches in the form of lines that would get thicker and thicker, and then go completely black. I asked for a replacement, but after several inquiries, the answer was unbelievable. I have to open the printer myself and look at the cable, according to their instructions. It seems that they are aware of the error, but are still selling that printer model. I wouldn't say anything if it were a cheap printer, but it is supposedly a high-quality and expensive device.
