After few head cleaning, ink counter running low, so ink ligh (red) flashing. Then ink counter runing out, so the light stayed on. After replacing both of ink, red light stayed on, because the compatible ink (chip) not recognized by printer. Check epson status monitor. Use original ink or refill and reset ink level counter.

This is the common problem of all brands of inkjet printers friend. You should atlease power on and off weekly once every inkjet printer. Otherwise the inkjet cartridges may claute.Call Epson service people they will come and clear it. Dont clean your cartridges yourself and waste valuable inks.

Hi, this is not a solution because I don't think there is one apart from buying new inks. Epson and all other inkjet printers do this to prevent the coloured print head nozzles from getting blocked. If they are not used for a long time the ink dries up and blocks the nozzles. Epson recommends printing at least once a month with all colours to prevent this. Printing in black only option will only work if the colored inks are OK. Whenever the printer is turned on it performs a head clean, this is why the coloured inks get used over time even though they are not used for printing.

To carry out a nozzle check turn the printer off, then press and hold the Ink (looks like a droplet) button and the Power on button for about 3 seconds. The printer will turn on and print a test pattern. It also shows how much ink is left in each cart. All the lines should be continuous in each colour, any gaps mean that the print head nozzles need cleaning. To clean the nozzles press & hold the ink button for 3 seconds. If badly clogged it may require four or five cleans, leave for about ten hours and do another set of cleans. If still clogged you may need to purchase a print head cleaning solution such as can be found here:

Hope this helps, please take a moment to rate this solution, thanks.

Hi there. The reason for your problem is that the colour cartridge contains cyan, magenta and yellow ink, plus a black cartridge of course. All the other myriad colours are produced by mixing these four basic colours. So, if you print red, it requires ink from both the magenta and yellow cartridges. Thus if your red produces a yellow print, it means your magenta is not printing. This can be due to a number of reasons, mainly an empty or faulty magenta cartridge or blocked magenta print nozzles.

If you wish me to help you with sorting out the lack of magenta, please post a new comment to this effect.

Hi, sounds like a dodgy ink cartridge. I would purchase a new black cartridge and fit and try that. Refilling epson cartridges isn't a good idea, if you can't afford originals, but compats instead of refilling them. a good place to buy is www.choicestationery.com I've never had any problems with their carts.

Hi

Try running the head cleaning cycles from printer utility. then try reprinting. You can press ink button for 3secs as well to auto clean printhead.

Hope this helps
