Hello lostados
A friend's Epson Eco Tank ET-2500 clogged up, because they did not use it regularly.
- I stripped it down and flushed-through the tubing using water and a syringe. I also "cleared" the tubing using fine guage steel wire. Youtube videos provided the help required.
- Following that we attached it to a Windows computer and purged the ink through the tubes until it printed all four colours. It still works.
At that time I was using a Brother cartridge inkjet printer. I forgot to print colour for too long and the printheads clogged up. I had a lot of work with that one, including buying "cleaning solution" kits. The result was wasted money. I could not get it to print properly again.
Now I have replaced the Brother with an Epson ET-3750 (on my cable network).
- I print half a page of text each day.
- The half page of text is in equal blocks of the following colours (Cyan #00ffff, Yellow #ffff00, Magenta #ff00ff, Black #000000).
- I produced the document with LibreOffice Writer, and exported it as a pdf. A link to this pdf sits on my desktop.
- I print half a page eachday, turning the sheet each day and using 1 3/4 sheets of paper per week.
If you disassemble your printer you may want to take photographs as you go - it makes re-assembly easier.
