Epson Epson Stylus Color 600

SUPER-CLOGGED Epson Stylus 600

I was wondering if someone could take a moment to confirm probable cause on a problem I'm experiencing with an Epson Stylus 600?

Printer sat on shelf for several years without use. I know that's bad and I expected clogs. Still, it's one of the best 4color inkjet photo printers I've seen and I'd like to start using it again...so...


Black print head nozzles REFUSE to un-clog.


Ran several standard cleaning routines. No change.

Purchased "Epson print head cleaning solution" and soaked the "cap assembly" pads overnight, several days in a row. SOME improvement.

Removed black cartridge, 'injected' several ml of "Epson print head cleaning solution" into the cartridge pickup nozzle with paper towel under print head. Messy! But some improvement.

It was at that point that I noticed the black cartridge was NOT an epson cartridge, but some 3rd party manufacturer. I also remember reading that 3rd party inks can CAUSE clogs. The 3rd party color inks are working perfectly and with no clogs. Color portion of nozzle check is perfect almost every time. HOWEVER, Noticed that while I did see some improvement to the black nozzle check / printing, as I printed more and more tests the black clogs seemed to get WORSE the MORE I printed, even with a FRESH 3rd party black ink cartridge.

I plan to go out and buy a GENUINE epson black ink cartridge and try re-running the cleaning routines and see if the EPSON black ink works better / does not clog. Wanted to know if anyone has seen this kind of problem before and if I'm on the right track to successful resolution of this problem before spending $30.00-$60.00 that could otherwise go towards the purchase of a NEW Epson printer ; ) .

Dan: After several years setting on a shelf, the chances of getting those clogged Printhead Nozzles to fully open up, are very low. Even after a year or so, its quite possible that the clog can actually damage the Printhead Assembly. AT THIS POINT: I would not bother to buy new Epson Ink Cartridges, unless you can actually first get all those nozzles to fully open and start firing again. Unless those nozzles are opened first, just simply installing new Epson Ink, will not usually make any difference and you will simply waste more money. Its also possible that you may not be able get the printhead assembly to open up and work correctly again, but using that "Epson Printhead Cleaning Solution" is your best chance. 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 for several days, to try and dissolve a 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...Again, Good Luck!
