Epson Epson Stylus Color 640

Epson 640 Stops Printing

Hi All,

I have Epson Stylus 640 that has always worked great and now appears to have problem. After printer 1 or 2 pages the printer stops printing the printer carrige is all the way to the left and the feed rollers are running continusly. The only way to stop the printer is to un-plug it. What is wierd is that the on/off button does not work, the print job will not cancel and no error messages are reported. The pages that are printed look fine and all the printer utilities and test pages work. This error is repeatable and always occurs after printing 1 or 2 pages. Does any one have an idea what might be wrong.
Nathan: I'm sorry, but I have not heard of that type of problem before. 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 and that could be causing problems. To eliminate that possibility, 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. A drop or two of a Teflon based lubrication or Tri-Flo lube is best. 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: http://www.epsonhelp.web1000.com/oil.html ...Good Luck! Denny Conway

Denny: Thanks for the info. After a little more work I have determined what initiates the problem but not why. It turns out that printing one particular PDF in black mode will cause the problem. Any other document and mode combination that I have tried is ok. Above when I was able to repeat the error it was always with the same file (I never thought to change files.) Anyway thanks for the help.
