| Evgen Test | 2010-08-31 09:42:53 | | 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! | |  | Wesley Pritchard | 2003-11-10 00:29:10 | | This program is a definate must have if you want to service your own printer. Using this program along with the servive manual (440,640,740) will help you to determine what the problem is. The program shows print head voltages, waste ink counter and reset, and recover print head functions just to name a few of the useful functions that this program has to offer. It returned my printer from a paperweight into a working Epson 640 in minutes. Even if your printer is working properly you can use this program ensure it will keep working. For less than $6.00 it is worth having. | | | Tim Plumley | 2011-12-03 20:31:01 | | I own an Epson Artisan 700- Prior to buying it I never heard of the issue with the waste ink counter and epson's built in error codes that render the printer useless after reaching a certain print count. I like a lot of you searched for fixes online. I happened upon (2manuals.com) by way of youtube. I was very reluctant about using this but I also didn't have many other alternatives short of giving in to Epson and their repair method and cost or the purchase of another printer.
I am very pleased that I went this route because my printer is up and going (printing) like it should be. I am a very satisfied customer.
Thanks,
Tim P. | | | Michael Reed | 2012-04-05 22:26:45 | | The reset key worked perfectly. The whole time to purchase a key, download the software, and reset my R2400 was about 5 minutes. Excellent product! Highly Recommended | | | mihail andronic | 2017-10-25 08:24:10 | | 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. | | | roger augusto ventura monasterio | 2005-11-14 18:33:49 | | i just wnna thank u for ur gret websit becoz its so easy and shortly . by other wise i need u to info me about service manual if it has trouble codes and diagnostic and troubleshooting procedures ?......thanx | |
