I know this is an old printer. I believe it came out around 2005. But it is my favorite all-time printer for making numerical charts that only I use. I have never needed the color feature.
Recently I bought another one on Ebay which was NEW in box! Of course the ink was dried out, so I put 2 new cartridges in it. But it still wouldn't print. I did a couple of cleanings and then a deep cleaning. Eventually, I started to get some results, but not very good. I put the print head in isopropyl alcohol & water, but that didn't improve it much either. I did a few more cleanings and deep cleanings. Finally I started to get results. But the bottom of the letters are still not visible. Obviously some jets are still clogged. I have also tried pressurized water on the print head from a spray bottle of water.
Anything else I can try before giving up on it?
