I have epson stylus sx215 printer error code w-11 can you help

SOURCE: My Epson Stylus NX 400 is not printing.

no it cannot. Those multi-colored cartridge system requires that you put in every single color, AND ensure that they are not empty before they will print. Even if all you want is a black and white copy.

Usually when this happens the printer fails to goes through the motions of the printing process, kind of stands still with indicator lights just blinking away. This could be as a result of either of these scenarios.
i.                     Ink cartridge has developed incompatibility or is incompatible
The Solution is to try an older/another cartridge (doesn’t matter if ink is finished. You must replace cartridge one at a time). If lights stop blinking it confirms that your cartridge has become incompatible or developed incompatibility. Also if your printer is the type that can work with only one cartridge, remove one after the other (closing back the lid/cover) to determine which in the set (black or color) has become incompatible. At the instance the incompatible one is removed and you close the lid, the blinking will stop (for printers that can print with one ink cartridge only). Just replace the incompatible one and start printing again. In most cases the issue is always with one cartridge. But if both are affected, you have to replace both. Because of this type of problem, always keep used cartridges somewhere safe; they come in handy for this type of troubleshooting.
ii.                   The Cartridge electronic panel  is dirty
The electronic panel on the cartridge that makes contact with the cartridge carrier inside the printer is dirty and needs cleaning.  This electronic panel is front part of the cartridge with copper “dots”.
The Solution is to try to clean this panel with a piece of folded tissue paper soaked in a bit of methylated spirit. Also try to clean the area in the cartridge carrier/holder that makes contact with the cartridge’s electronic panel (Usually this is more difficult). If you cannot reach it with your fingers, use a stick or something with tissue wrapped around it. Allow to dry well and return the cartridges, close the cover. The blinking should stop if the electronic panel is the issue. Once the blinking stops the printer will print.

SOURCE: How to Change ink cartridge

#1 Wait until you are out of ink. The warning light and ink-low notifications come on well before the ink cartridge is empty, and even if it runs out of ink in the middle of a print, you can replace it then and finish the print with no problem.
#2 Lift the lid of your Epson inkjet printer to expose the ink cartridge replacement button. Make sure you have plenty of light so you can see what you are doing.
#3 Press the ink cartridge replacement button. This will loosen the empty ink cartridges so they can be pulled up and out.
#4 Fill the empty cartridge at an ink-refilling location, or buy a new ink cartridge to replace the empty one.
#5 Insert the new or refilled ink cartridge into the holder with the same orientation as the previous one.
#6 Press the cartridge replacement button to charge the system and close the printer cover. Charging takes about one minute

Thanks

its because the ink housing will only aline when the ink is empty its not like any other printer that you can line the housing up. Wait until you run out of ink then lift up the lid and the housing will be alined - its stupid system and epson dont tell you this when you buy the produc
