Since I had a syringe of black printer ink that worked just fine on a Canon
250i, I decided to try filling the cartridge on my Dell A920.Its gone from streaky printing - to printing completely blank pages.
Is this a problem of priming the nozzles - or incompatible inks gumming up the works?
Thanks.
Epson 2200 owner myself. I would try to run nozzle cleaning. If you don't have pref's that perform this try re-inserting the cartidge and let the automation take care of priming. You might have to do this three times. Anymore = fail.
All the Epson printers I've seen, the print head was part of the printer so it doesn't get replaced with the cartridge - now I avoid Epson, once they're blocked - they're blocked!
The Dell cartridge nozzles just needed priming - I did that by sucking.
The ink tasted *VERY NASTY* and I got a black tongue - but it now works.
There were a couple of colour cartridges that felt like they had some weight in them, I got one of those going again with a few minutes in an ultrasonic cleaner and leaving them to soak overnight.

what fluid did you use in the ultrasonic bath / soaking ?
Water with a dash of Stardrops detergent.
The ink is water based - any hydrocarbon solvent would curdle the ink like putting vinegar in milk!

isn't detergent a hydrocarbon? So I take it that de-ionised water as the fluid rather than methylated spirit or paraffin is the correct medium.
I saw a BP oil company branded bottle of washing up liquid once years ago.
Not sure if it has any relevance to this topic, years ago I saw in student digs a physics student had written on the bathroom wall; "were it not for the difference between carbohydrates and hydrocarbons - we'd dissolve ourselves when we fart in the bath!".
The Stardrops detergent is distributed by: Star brands Limited Birmingham, UK if you want to tap them for more info, if I didn't have any Stardrops I would've used washing up liquid - most places that sell ultrasonic cleaners offer some "special" detergent for use in them, but I rarely find myself overwhelmed by excessive disposable income!
Acetone is water soluble, but even diluted may damage some types of plastic.

Perhaps its the surfactant action that is required in ultrasonic baths, rather than oil/grease dissolving function.
Horses for courses - some usonic tanks were designed for solvents, but most of the useful solvents have been banned because they damage the ozone layer.
Even electronics manufacturers solder with water soluble flux so it can be cleaned in water.
Before the chlorinated solvents, they used alcohol - but that was stopped because of its flamability.

pI always soak the cartridges that have nozzles in a shallow container of water overnight, water just deep enough to extend to the bottom of the tank itself, putting the nozzles 1/8" +/- under water. Then I fill them about 1/2 full, set them on end so that the nozzle end is up for about 1/2 hour or so. Then put them upright in their normal position for another hour to let the ink fully diffuse throughout the sponge, and then start printing again. I recently refilled some HP and some Lexmark cartiridges more than 10 times each as I was printing some brochures for a non-profit organization. Cartridges still printing perfectly.
