It sounds like there is a bit of dried ink either in the ink cartridge or printhead which is quite common. I would advise to perform a few printhead cleans 2 or 3 this should resolve the issue.

Unfortunately, we don't sell a refill kit that works with Epson XP-312 ink cartridges so we wouldn't be able to confirm that these compatible Epson T1816 multipack cartridges can be refilled or provide you with the correct ink to refill them. We only deliver within the UK but it's quite possible for you to have as many compatible Epson T1816 ink packs as you need delivered to an address in the UK if you have a family member who can get them to you abroad. Please be aware that our compatible T1816 ink cartridges are only guaranteed to work in an Epson XP-312 printer that was purchased in the UK.

These premium brand compatible Epson T1816 cartridges contain high quality dye-based ink.

It's possible that cartridges from an old printer could be compatible with a newer printer from the same series. However, we're sorry to confirm that the Epson Stylus DX4050 printer uses different cartridges to the genuine or compatible Epson T1816 ink cartridges found on this page for use in the Epson XP-312 printer. To see all of the cartridges that we stock for either of these printer models please use the links below:

To see the single compatible black Epson T1811 ink cartridge from this multipack please click on the following link: http://www.cartridgesave.co.uk/T1811-CPT.html

Each ink cartridge is given a unique manufacturer code or cartridge number. For example, this pack of four compatible Epson ink cartridges replaces the genuine Epson T1816 multipack so they're referred to as "compatible Epson T1816 ink cartridges". The single magneta ink cartridge code is T1813 so you need to find the cartridge labelled "T1813" and replace it in your machine to refill the magenta ink. The cartridge numbers for the individual inks contained in this compatible Epson T1816 multipack are as follows:

Compatible black ink cartridge: T1811 (C13T18114010)
Compatible cyan ink cartridge: T1812 (C13T18124010)
Compatible magenta ink cartridge: T1813 (C13T18134010)
Compatible yellow ink cartridge: T1814 (C13T18144010)

I believe that you ordered the T1816 multipack, I have listed the colours below along with their cartridge numbers:

Black: C13T18114010
cyan: C13T18124010
Magenta: C13T18134010
Yellow: C13T18144010

I hope this helps.
