Epson Epson Stylus Color 440

Epson stylus 440

Can anybody help, I have cleaned the head of my printer, at first it was printing black but was mis aligned using the alignment tools I was able to align the print but there was no color, I cleaned it again now nothing is being printed, but when I run the cleaning utility I can see ink both black & colored at the ink pad, what should I do, thank you...
jerrie_chua: If you can visually see stripes of the three colors, plus the black, on that felt Cap Assembly, that usually indicates that there is ink in the cartridge and that the Printhead Assembly is not at least completely clogged. It's of course possible, that you may even have an actual hardware/parts problem [failing Printhead Assembly or Main Board Assembly] and that could be the reason that the colored ink is not being printed onto the paper. Just to let you know, the ink on that felt pad gets there thru a vacuum type action from the Pumping Mechanism, in the Cleaning Station Assembly. So as long as that vacuum is there, ink will be pulled out of the ink cartridges and printhead assembly and onto that felt pad. then the ink is pulled thru that pad, thru tiny hoses and onto the Waste Ink Pads. When the main board sends the signal to the printhead nozzles, theuy actually fire and ink is placed onto the paper. So, if that signal is not sent, or the printhead nozzles do not actually fire, then no ink goes onto the paper. The only thing I can recommend is that you try running several sets of "Printhead Cleaning Cycles" and "Nozzle Tests", to try and get the ink to start flowing correctly again. If after 5 or 6 sets of those tests, no ink prints out onto the paper, then I would have to guess that you probably have an actual hardware/parts failure, especially if you can actually see the ink still getting onto that felt pad area. Running a lot of "PRINTHEAD CLEANING CYCLES" and "NOZZLE TESTS" can use up the ink inside the cartridges, but at this point, you may have no choice. On some models, you could install a NEW CARTRIDGE and run between 10-15 cleaning cycles and tests and its possible to empty the new cartridge. Also the color inks run out faster, because theres far less of each color inside the actual ink cartridge [usually at least three colors share the same ink cartridge], compared to the black ink cartridge. If you can see some color showing up on the actual nozzle test, then its always possible that you could have a partially clogged printhead assembly. In that case, you might want to try using the Epson Stylus Head Cleaning Solution, available through fixyourownprinter.com, at http://www.fixyourownprinter.com/kits/epson , 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. 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 http://www.inkjetprinterhelp.us/EKR.html ...Good Luck!

jerrie_chua...ANOTHER THOUGHT: Anytime you remove any ink cartridge with the power turned on, the printer assumes that you will install a brand new ink cartridge and it automatically resets the "Internal Ink Counter" back to zero and automatically resets the "Ink Level Indicators" to full. Thats why Epson says you must install a new ink cartridge, anytime any older style ink cartridge is removed. On the older style printers, now it thinks the cartridge is new and of course full. Lets say that the old cartridge had less than 1/4 of its ink left. What can happen is that your printer will use up that 1/4 of its remaining ink and then it runs itself dry and air gets into the printhead nozzles. It actually runs out of ink and never know it, because it still thinks it has 3/4 of the ink left inside that cartridge. Then the air that got into those tiny printhead nozzles, causes the ink residue inside those nozzles, to dry out and that usually results in clogging. All new Epson Ink Cartridges are sealed and there is pressure put in them at the factory. When you install a new ink cartridge, that internal air pressure is what causes any air that got into the nozzles [such as when you removed the old ink cartridge] to be pushed out of the nozzles and primes the nozzles with fresh ink. If you reinstall the origional cartridge that you removed, it not only has already lost its internal air pressure, but now there is air inside of the actual printhead nozzles. That air starts to dry out any remaining ink inside of the nozzles and that normally results in clogging. Thats why Epson says to always install a New Epson Ink Cartridge, anytime you remove any ink cartridge, even if its full of ink. Also, if the old cartridge was out of the printhead holder assembly for more than 30 minutes, the nozzle may have already started to clog. If you choose to just reinstall an old Epson Ink Cartridge, with no pressure inside it will also be difficult to get the ink to start flowing again. You may have to run 6 to 10 sets of "Printhead Cleaning Cycles" and "Nozzle Tests", to actually be able to get the ink to start flowing correctly again. If you did happen to remove the old color, or even the black ink cartridges, with the printers power turned on, then its always possible that your printer reset and that cartridge may actually be empty or bad. Just so you will know: Even after that Red Ink Light turns SOLID and stops your printer, there has to be a little ink left in that cartridge, or air would get into those tiny printhead nozzles and possibly cause clogging or even actually damage them. Thats why you can still hear or feel a little ink left in those empty ink cartridges, once you remove them for replacement. One individual printhead nozzle is so tiny, that it will not accept a human hair, so you can see why they can get clogged so easily, or even why the nozzles can be so easily damaged. Once any ink cartridge is installed [with the power on], it causes the printer to go thru "New Cartridge Initialization", which is another reason why that remaining ink is being consumed. If you turn off the power first, the printer will never know you removed and reinstalled the same ink cartridge, so it will not reset the internal ink counter or the ink level indicators. However, as you have already let the internal air pressure escape, that remaining ink in the old cartridges, would probably not be used anyway. Normally, you need to run sets of cleaning cycles & nozzle tests, just to try and get that ink to start flowing again...Again, Good Luck! Denny Conway
