printing problem in my epson Epson DX8400 printer.

[rohit.raiirvine]

I have just put a completely new set of compatible ink cartridges in my Epson DX8400 printer.
The printer recognized the cartridges OK. However, I m having very bad problems with black printing so I ran several stores for cleaning and printing cycles in an effort to clean the printer nozzles. even though I would also contact to epson support number After several services the printer suddenly said that it could not recognize now what can i do now how can i solve my problem?

the biggest problem with "compatible" cartridges is that they use identification methods that more and more manufacturers have changed with the printers; when you put a cartridge into a printer, it tells the printer what kind of ink it is and how much there is (kept on a counter), manufacturers do not want "compatible inks to run into their printers because it detracts from their ways to making money (you buying their ink) and they update the identification codes frequently, eliminating "compatible cartridges" from properly identifying itself as Epson Ink, and therefore the printer refuses to use it.

How to fix that, only 2 ways, 1 buy original products from Epson, or buy refilled Epson cartridges.

this is happening not only with ink-jet, but with toner based printers i.e. laser printers and even on plastic card product printers (identifications printers)
this may sound stupid on manufacturers but aside the profit on selling refill products for printers, there is a very long list of sub par products being used in the past buy user buying cheap, untested Chinese's products among many other "copycat" products and a great many repairs "on warranty" because of sub par products being use in the printers causing internal damage to the printers, so the manufacturers are trying to prevent those from happening as well.

for the money, especially if you rarely use colour, I will suggest getting a Laser printer, a 80$ cartridge produces over 1500 Pages, where a 40$ black inkjet cartridge produces at best 500 pages... the cost efficiency is obvious.
