Epson Stylus DX4400 is not supported, and it seem to be impossible to reset the waste counter. ========================================= You have to use Epson DX4400 Service Program - search in our site

Thanks for the program and manual. I was able to revive a 2 year old 4900. I had 100% blockage in 8 of the 11 heads, and over 50% blockage in the last three.... I ran the ink charge with cleaning fluid. Now I have 100% of the nozzle check pattern on ALL of the heads. I was blown away. I thought for sure I was going to pay for a new head. So, thank you. I also have a an older Epson Stylus Pro 4000. It has been sitting a while and the heads are dried up. Do you have the same program and manual for this printer? I would like to try to revive it as well. If you do could you just send me a link? Thanks again

I have order it but it can not work for reset wast ink pad. When release a new it too sad to order with 19.99$ with nothing can do. ====REPLY==== This printer model has separate Waste Ink Maintenance Box with its own IC chip. You can replace Waste Ink Maintenance Box or reset the chip on the Waste Ink Maintenance Box. This information is clearly stated in program description at our site.
