Will these work in 7550?

I don't know. Mine is a 6220. These are kind of cheap, though. I've had them break in half while winding the bobbin. Wouldn't recommend.

You might want to check on this on the internet, mine is a 7520, so I really don't know. All I know is that this ink is as good as the name brand ink and lasts a long time.

I bought this for my 7520, but suggest you try the "Will this fit my printer?" section & it will tell you for sure.

I have a Pfaff 7550 and they work just fine. They are exactly the same as the ones I've gotten from my Pfaff dealer. Hope this helps!

as long as you have 3 burners/control knobs, they will fit it. if you only have 2 control knobs/burners it will use 7522.

I would say no because the seller states in the description which printers this ink is compatible with and I don't see the WF-7520 listed but to be sure I would advise you to email the seller and they can tell you exactly if it is compatible. The ink was compatible with mine because I have the WF 520 which is listed. Hope this info helps. :)

I bought these back in May and they worked perfectly in my unit. Here's a link within amazon: http://www.amazon.com/gp/product/B003VNKNF0/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

Yes - as long as it has the # 273 - they will work fine. I have ordered 2 sets and my Epson XP-620 has accepted them just fine. No Problems. Good Luck. Victoria

They should be for an 850 and 860. Be careful about second party inks though, as Epson printers are very sensitive. My 850 malfunctioned with these cartridges.

As long as the specs are the same as the one that is in the computer now it should work. I installed them on a Intel motherboard and had no issue.

Yeah, from experience these will fit 7507 but I recommend splurging a little more and opting for bulbs with 360degree LEDs

Yes the Optiplex 755 should have (check specs) a PCIE slot which this adapter would fit into.

Sorry can't tell you. The only compatibles I have recently purchased were trash. I threw them away. These may be them.

My unit is the 756 and it fit perfectly. If they are the filters that your machine ask for then get them, they fit my machine.

They should work. You need to make sure you have the steel c-channels as well. Depending on the model you might or might not already have them.
