I've had the same problem. Take out the cartridge and wipe the copper strip gently with alcohol. Not a lot of alcohol. Just enough to wipe off any dirt. Or, unplug the printer for a few minutes and then plug it back in to reset the memory. The error message you are getting is for a dead cartridge. Take it back and get a different one. Even if it's filled, it can still be dead. There's a micro chip in the cartridge that's suppose to prevent refilling of cartridges. I have had no luck going to Walgreen's. Go to the store and buy boxed refilled cartridges or go to inkhets.com . Don't try to do it yourself. Not worth the hastle.

Red Flashing lights


Hey,

Remove the cart ridges, restart printer, does the lights still flash? restart printer, place cartridges back in, make sure the tape is removed from the cartridge. also you can try cleaning the contacts.

So after you have connected the carts again, restart printer. how is it?

Thanks,
Ekse

Flashing red/green lights


The Waste Ink Pads in your printer are saturated with ink and the waste ink counter has exceeded its limit. The Waste Ink Pads should be replaced as soon as possible. You can overcome this problem temporarily by using the SSC utility - download from

http://www.ssclg.com/epsone.shtml

and reset the Protection Counter. This will stop the red lights flashing and restore normal operation. However, remember that eventually ink will overflow from the waste ink area and make a dreadful mess, so you must change the waste ink pads before this happens. If you want to have a go at this yourself, the service manual can be downloaded from

Change printer ink


Turn on the printer.
lower th epirnter's output tray, pull out the extension, and open the cover.
press and release the ink button.
if your ink lights is on or flashing, the printer head moves to the left, and the cartridge that need to be replaced stops under the ink out mark.
open the cartridge cover
Pinch the back tab of the empty cartridge as your left it out of the printer.
shake the ink cartridge 4 to 5 times while it is still in the package.
unwarp the new ink cartridge and lower it into the holder. Push down gently until the cartridge is firmly seated.
repeal the procedure if more than one ink cartridge is out.
close the cartridge cover.
close the printer cover and press the ink button.
The green power light flashes and the printer makes noise. charge takes about a minutes. When it's finished, the green power light stops flashing and stay on, and the red ink light should go out.
