Hello, I am interested in the follow-up of this message posted on 1/05/2004:

Joellen: When the ink light or lights [some models have two ink lights] are on SOLID and the power light and paper light are both FLASHING, that indicates a FATAL ERROR on most Epson Printers. I'm sorry, but just as it sounds, that is the worse possible error on your printer. You would probably need to try and locate a Service Manual on-line, that you could download for in-depth troubleshooting and possible disassembly, if you want to try and locate your possible problem. There are approximatly 10 different things that can cause a FATAL ERROR and most of them involve HARDWARE PROBLEMS [bad/defective/failing electrical parts] in the "carriage assembly" or "paper feed assembly". Check for an e-mail from me that may help further...Good Luck! Denny Conway

Could you send me the e-mail your message promised?

Paul: I have e-mailed you that information. I hope it actually helps. The most common Fatal Error is caused by the Carriage Assembly. PROBLEMS: Although it's possible your printer has an electronic or mechanical failure, the most common problem is that the Carriage Assembly is simply DIRTY and or DRY, causing it to stick and make noises. That usually results in the printer loosing track of just where the Print Cartridge Holder Assembly is actually at and that can cause the Error Light/Led to come on. Sometimes when the printer looses track of where that assembly is at, it then keeps telling that assembly to keep moving and can even cause it to slam into the end of the printer. Try wiping off all around the round metal carriage bar or shaft [that the Print Cartridge Holder assembly moves back-n-forth on], with a lint free cloth. Also clean the outside of the metal bushings with Q-Tips, that the carriage bar passes thru, on both sides of the cartridge holder assembly. You can also use alcohol on the cloth, if there is a lot of build-up on the carriage shaft/bar. Then lube the metal bar on both sides of the holder assembly, slightly with a precision oiler, not a spray lubrication, or the appropriate grease thats used on some of the newer models [C40UX, C62]. A drop or two of a Teflon based lubrication or Tri-Flo lube is best on the older models of Epson Printers. Manually slide the holder assembly back and forth to spread out the lubrication and wipe of any excess lube or blackish build-up that appears on the bar. Look for an e-mail message from me with more in-depth information, that might help you in that area. You can check out this link, supplied by WES, to see different lubrications: ...Good Luck!
