Problem/Solution SummaryProblemSolution

Printer does not print

Printing is patchy, faint, uneven, or intermittent

Make sure that the printer is turned on and is on line. Both the POWER and ON LINE lights should be on.

Make sure that the printer and computer are connected. Be certain you are using the correct cable and that it is firmly plugged in at both ends.

Turn the printer off and on again to reset it. While the printer is turned off, make sure the paper is loaded correctly.

If the printer still does not print, try the self test procedure described in Chapter 1. If the self test works correctly, the printer is all right and the problem lies elsewhere. If the self test doesn’t work, take the printer to a qualified service center.

Check that the ribbon is seated correctly.

Check that the ribbon moves freely in the cartridge.

If you have been using the ribbon for a long time or for a large amount of printing, it may need to be replaced.

It is also possible for the print head to wear out if the printer is used frequently and for long periods at a time. Contact an Epson dealer if you think the print head needs to be replaced.
