Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

Expert:  Nathan replied 1 year ago.

These symptoms point to either a clogged/contaminated print head, or a faulty print head (or the logic board that controls it).

You can try going into the setup/maintenance menu on the machine and running the “clean print head” function, if it doesn’t work try it a second time. If it still doesn’t print anything, you’ll need to do a manual cleaning.

I have to caution you up front though that the manual cleaning process is messy and time consuming. It also has a low chance of success, if you see no improvement at all from the automated cleaning. It is most likely a hardware failure (bad head) which the cleaning can’t fix, as printheads are a wear item and do fail with time/use.

That said, it doesn’t hurt to try, if you wish. Let me know how the built in cleaning function works, and I’ll advise further if needed.

Best regards, ***** ***** for the news,

Nathan

Already did that. Printer is only 1 week old. I ran out of ink and used an off brand from office world and a day later is when this problem started
Expert:  Nathan replied 1 year ago.

That is what causes this problem, the generic inks are specifically advised against by epson, and their use voids the warranty.

The problem with them is that the pigments in the cheap ink is not as fine as the oem ink, and causes the nozzles to clog, leading them to overheat and fail.
We can try the manual cleaning, or you could try returning the printer to the store where it was purchased and being sure to use only the correct ink on the next one.

To try manually cleaning the print heads:

Open up the printer, and look for the "carriage" that goes back and forth (on metal rails) over the paper while printing. This is the printhead.

You'll remove the ink cartridges from the printer, then clean on the bottom of them (focus on the ink port/hole) as well as inside the printer where they mate up using qtips and rubbing alcohol.

Unfortunately your model does not have a removable printhead, so it will have to be cleaned in place. Fold up a piece of paper towel in quarters the long way, saturate the middle with alcohol, slide it under the print head, and pick up on the ends while moving up and down to clean it (think of drying your back with a towel).

When cleaning the port on the print head that the ink flows into from the cartridge, also try using a qtip to "pump" the liquid down into the port and force it through, which will help to dissolve any clogs. If possible, you'll get better results by using a syringe and appropriately sized rubber tubing (that will fit into the ink inlet port) to force the alcohol to flush through the head)

After all of this swab again with a few dry qtips or give a blast of compressed air to dry everything well, then put it all back together. You can now try to print, or run the automated print head cleaning function in the setup menu. You may have to run a few pages through before everything starts flowing properly again.

If none of this helps, then you've got a faulty print head(s) which would need to be replaced.

If you have any other questions, just let me know. Otherwise, please do remember to rate my service, hopefully I have earned an “excellent”. I also invite you to contact me directly with any future support needs at http://bit.ly/1Md4aNC

Thank you, ***** ***** a good day,

Nathan
