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 your WIC PROGRAM! | |

BRILLIANT!!!!!!!
You deserve every dollar you make from your extraordinary program and service. THANK YOU SO MUCH!
In awe of you, that you could produce, make, create this reset program so that even I, 78 yrs. old, mostly blind and not much of a computer geek, could do it! I al thrilled and jumpinga round because you saved me about $300>$400 from not having to buy a new printer. | |
