A friend brought over a dead 4900, to see if we could revive it. After cleaning the capping station, head, etc per Dana’s video instructions, and a power clean, we tried printing a nozzle check. It’s remarkable in that it is ENTIRELY blocked on all channels. Not even a hint of any of them printing. I’d post a pic, but it’s easier to simply say take a blank piece of paper and that’s what it looks like!
My guess is that the lines are solidified, since this printer has been idle for two years, and not all of that time was in climate controlled space. Is there any remediating this?
