My printer stopped printing with the error as \"General Error\" Epson quoted me $60 to send an engineer to fix my printer. After reading through the information on this site I decided to fix it myself. Found the problem was related to the waste ink pad counter. Only 10 minutes, I had the the printer working. The printer tested fine and has done approx 150 pages since with NO issues. Thanks for the WIC program!

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!!!
