  My Epson R2880 stopped printing and showed alternating ink and paper flashing lights. I had an extended warranty that I purchased with the printer but because I didn\'t register the warranty within 30 days I was told by Mack Camera that they would not honor the warranty. So after much research and web surfing I found myself at 2manuals. I wasn\'t even sure that the wic was the problem and I had serious doubts about spending more money on what could just be another scam like the extended warranty was. However like one reviewer said, what was $9.99. Well I downloaded the program, obtained the $9.99 pin code, loaded the software, and exactly as the video shows I was up and running. I couldn\'t believe it when the printer sprung to life and was ready to print. Hey, try it. You\'ll be glad you did.

  I was able to reset an ET-4800 using a USB cable. At first I could not reset due to wireless connection but after changing to a USB it worked great. Epson tech support told me a complete lie. When I called, the first tier said it could not be repaired so I had him move me up to next level. That tech support lied to me as well, telling me they recommend getting rid of the printer as it cannot be repaired. Such LIARS!!

  I don't get any reply to my email. Is there a customer service person at the business? My question is: I see that you have the "HP OfficeJet G85 Service Manual and Parts List". How many pages does the manual have? Please answer my question by email, myccma@gmail.com. Thanks in advance.
