Brother MFC-580 Ink

very quick service was here in two days and very good inks

The ink is not printing properley it is very patchy.  Could you explain why?

Britink response; we would always advise cleaning your printer before you install new cartridges. If the problem still exists we would happily replace this cartridge under our 100% satisfaction guarantee.

Good quality and great price , quick delivery.

If you need ink in a hurry, then Britink is the place to order from. Jettec, my choice, is a top product at a great price& delivery is superfast. Many thanks.

JetTec must have saved me a fortune over the Canon cartridges.  As WHICH magazine is my guide to these things I have not been disappointed.  To my eyes there is no difference in the quality of the colour representation between the original Canon cartridges and JetTec. 
Britink's service is mercurial - thankyou.
