Digital BW, The Print

Thanks guys..I am waiting to get some pigment cleaning fluid. I have stopped messing with the windex and inserting it directly into the head. I do put a paper towel under to catch all the spill. So far, it looks like nothing has been damaged so I am stopping to mess with it. I do not think the heads in a 2200 are removable. Anyway, not sure i'll be good enough to remove them.

Right now, it's only a small hole (1 bar) in the nozzle test. It will only show a thin white line when i print high speed on regular paper. If i use 2880dpi and photo paper, then the line does not show up.

Maybe by using the printer a lot, after a while, the dried ink will start melting !!! it also could be some hardware issues but I doubt it. I found out that the printer has been sitting on its side for 3 years in a garage...

I like the printer a lot..

Yes. I had similar experiences with an old EP1200. It had a single nozzle I could never clear after using paper towel in that way. I finally removed the head from the machine, put a plungerless syringe full of flushing fluid on that chamber and applied a very strong vacuum to the nozzle side. That cleared it and after replacing it in the machine I got all nozzles firing. Unfortunately,I must not have gotten the ribbon cable securely back into the head because about half way through the first good print the machine crashed. Yep.....You got it, the main board blew. I replaced it and the head with components from an old EP750 I came across and it now works well. I still have the board and head and I may sometime repair the board and put it and the head into the old 750 to check them both.

I'm never dismayed by failed experiments but I do, at times, regret the time lost that might have been used more productively.

Regards,
Duane
