Ace. I downloaded the programme which told me that one waste ink was at 65 % and the other was at 100% This told me that the programme was communicating with the printer (Another utility I tried would not even talk to the printer.) This gave me confidence to buy the key to activate the reset. It worked in seconds and my now perfectly functioning A3+ printer is no longer a pile of scrap. If only Epson UK were this good!!!

Looks ok, working fine, save a lot of time in my case, finding a bad sensor in 15 minutes, but can not read counter information`s. Only can reset.

Wow! Epson wanted standard charge of £118.80 to replace my ink pads. So I bought a set for about a fiver (on eBay). But then Epson would not provide a reset code - they still wanted £118. 80. Then I came across this service and hey presto they provided a code for under a tenner. They deserve all the business they can get. Well done. From Ken Fuller

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
