It worked fine. It was just that we didn't know where to start with opening the program. I couldn't get it to install so there was an icon that took us into the whole program. I found out that if I clicked on the one icon it opened the one we needed. The service manual will be of great help for later when the ink absorption pad needs changing. Thanks for your prompt attention. Regards, Ruth

A stressed week with Epson-ET-2800... It worked perfectly. As I have the same problem again, I will definitely buy from them.

Good day. I have to clean my printer head EVERY hour. Then it prints fine. Until I leave it for an hour. So this leads to waste pad full and I have to purchase a key every time. Is there another way to go around this problem please? I cannot afford to buy a key every week. =======Reply ======== You have to make 2 things - clean parking station first - then inks will not dry on printhead; - use high quality inks.

Ja sam prezadovoljan, kupoprodaja je uspesno zavrsena a stampac Epson Stylus Photo P50 je odmah po resetovanju proradio.Ovo prvi put radim ali svakom preporucujem saradnju sa ovom firmom, zaista su korektni.

An excellent service that works. Don't be fooled by the printer manufacturers that you are trapped into buying their over priced cartridges because you thought you were doing the right thing by upgrading the firmware. The only reason for their upgrade was to stop you from using your own cheaper 3rd party ink cartridges. If you accidentally did do the upgrade as they recommended don't worry as you can undo that costly mistake with the help of "wicreset". It really works. Also did you know that 3rd party cartridges actually contain around 25% more ink than oem cartridges?
