I have recently, finally, replaced the starter cartridges that came with my 4 month old 9900 - that's how little printing I do! I purchased the 150ml cartridges thinking that they would be sufficient for my printing volume. Cartridge after cartridge failed on the first try...... I would get an error message saying that the cartridge was faulty and to replace it. My dealer told me to push the opening of the cartridge with a paper clip or small screw driver to remedy the problem. That worked on some of the cartridges but not on two of them - vivid magenta and yellow. I have now gone through three cartridges of each color and have been a host to one of the most stupid repair individuals that I have ever met! This guy wouldn't make a move without calling Epson who insisted that he do the cartridge bleed routine. A small tube is connected to the inlet on the bottom of the cartridge and while blowing into that (at a controlled pressure) a small screw driver or paper clip is inserted into the outlet at the top of the cartridge so that any trapped air bubbles can be let out. This guy tried this with two new cartridges resulting in ink leaking into and out of the cartridge. What an unbelievable fiasco!! Nobody, nowhere, nohow should have to go through that kind of routine to get an Epson cartridge to work! The odd part of this is if I re-install the almost spent starter cartridges they are always recognized. This, to me, says that there is a big time cartridge problem and maybe more so for the 150ml size.
Have any of you experienced this type of problem and..... what size do most of you use? Maybe I have to forget about using the 150ml. One thing this repair person did mention was that Epson was having a tremendous problem with ink cartridges.
sometimes - particularly with magenta cartridges for some obscure reason - cartridges are not recognised
putting the cartridge in and out 3 or more times can fix it
holding down the pause button also fixes it sometimes with/without power on / off
there seems to be some chips which have difficulty being seen by the printer
once 'seen' they continue to work fine without further problem
