Epson Epson Stylus CX6400

Epson CX6400 - does not print magenta or yellow

Any ideas about what I need to check to get my printer to print out from the magenta and/or yellow ink cartridges? I have replaced the Epson cartridges, the printer recognizes that the cartridges are full however no colored ink prints. When performing a head cleaning and nozzle check pattern only black and blue ink print on the check pattern page. I have uninstalled and reinstalled the software, drivers and all updates - still no luck. Don't want to buy a new printer until I have exhausted all options. Thank you
canyondmc: It's possible that you may even have an actual hardware/parts problem, such as a failing Printhead Assembly or Main Board Assembly. However, normally the most common problem is clogging of the Printhead Nozzles, especially if you were actually using Non-Epson Ink Cartridges. You might want to try using the Epson Stylus Head Cleaning Solution, available through, at , but it will only help, if there is an actual clogged printhead assembly. When it opens, click-on "Epson Stylus Head Cleaning Solution" thats listed for your particular printer. The Epson solution sells for around $10.00 plus shipping. It includes a syringe and some Epson printhead cleaning solution, which is designed to dissolve most clogs, especially if you were using Epson inks. This is the same chemical used by Epson in their service department. You can try it if you want to and see if you can get the printhead nozzles to open up again, but that will only help if they are actually clogged. It was basically designed by Epson Company for use on their older models of ink jet printers, but people have been using it on the newer models, with success reported. IF YOU DECIDE TO, TRY THE "EPSON STYLUS HEAD CLEANING SOLUTION", JUST REMEMBER: The "nozzles" inside the printhead assembly can be easily damaged by using to much force on the plunger of the syringe. Damage can even occur when you are using the Epson Stylus Head Cleaning Solution method, if you actually try to force the fluid thru the nozzle. To much force/pressure can damage the little tubes inside the Nozzle Assembly and then it will never work again. One individual printhead nozzle is so tiny, that it will not accept a human hair. You can see why they can get clogged so easily, or even why the nozzles can be so easily damaged. The correct method is to use the syringe to add the fluid into the nozzle and then leave the fluids set inside the nozzle for a day or two, to try and dissolve a possible bad clog. If you remove the "Top Cover Assembly", then you can leave the printhead assembly parked in its normal home position, at the far right side. Then any ink & fluids that are purged during the cleaning, will normally travel thru the cleaning station hoses, to the waste ink pads. If you have the "Print Cartridge Holder Assembly", positioned away from the home position, then you will need to slide strips of paper towels or coffee filters under that assembly, to soak up any expelled ink and fluids, or it can get all over. Sometimes you might have to use the fluids several times to be able to dissolve the clog in the printhead nozzles. Sometimes the clog will never dissolve, or it actually damages the nozzles. The longer the clog has been in, the worse it is to remove. Again, if the cleaning fluids don't help, then its generally time to invest in a new printer. In some more expensive printers, you may want to get an estimate to replace the printhead assembly, but as a general rule, its not really economical to do in the smaller Epson Ink Jet style printers. You can generally buy a new small printer cheaper than you can have your old one repaired for. EXAMPLE: The printhead assembly in the "C80" Printer sells for around $120 to $130. There is a REVIEW of the "Printhead Cleaning Solution", as well as general "Printhead Cleaning Instructions", that is available to view at ...Good Luck! Denny Conway
