Hello everyone,
I recently got a Roland VS-640i from an auction. I bought it without knowing if it was working, and as soon as I got it, I tested everything, and it worked well.
It was running with double CMYK and some non-branded cartridges, so I changed it to the same aftermarket ink that I use in my other VS-540. First, I switched to double CMYK to check if everything was working, and it did. After that, I checked that it was running constantly clean, then I changed to CMYKLcLmLk+Clean. After that, the black stopped working, and after a few cleanings and fill inks, the entire ink system stopped working.
Now, I’ve checked the fuses on the main board and power supply, checked all the tubing, changed the dampers (I did this when changing the ink and when setting it to 7-color), removed the printhead and flushed it through, which seemed to show that all channels are clear. I’ve done everything I know or could find online.
The weird thing is that when I run cleaning or fill-up cycles, the ink ends up in the drain bottle normally, but when I do a test print or something, nothing happens—not even a single nozzle.
My guess is that some electrical component on the printhead is damaged, or a pump that needs to be controlled to pump the ink to the head while printing is not working, only during cleaning.
Is there any way to test what’s wrong? I don’t want to replace the printhead on suspicion because when flushing it, everything looks clear and not clogged.
I could put the printhead from the VS-540 into the VS-640i or the other way around, but I don’t want to damage the working printhead of the VS-540. Has anyone ever done this, or has anyone had the same problem or any guesses as to what might be wrong?
Or can anyone tell me where and what I need to measure with an electric multimeter or voltage detector to check if the printhead is being controlled properly and to make sure that it’s the printhead itself and not something else?
