Bloomin' Brother Ink saga.

I changed the various ink carts on my Brother printer about a month ago. I bought high capacity Think compatible ones from Choice Stationery Supplies. Since then, no problems, although we use the printer fairly rarely (perhaps 10 - 12 sheets in that time).

Today it wouldn't print blue text and when I ran a test print it clearly showed a problem with cyan ink. So I ran a series of cleaning cycles. Sometimes these seemed better, then worse. At the start of this process, all inks were showing almost full.

Eventually I removed the cyan cart and noticed that although it clearly had ink in it, there wasn't any in the 'output' spout bit. When I pushed a cocktail stick in there, air actually rushed in, so I checked for the little hole that should let air in. I had pulled the tape off OK but it had left a film of clear tape still there, so it was blocked. Success, I thought. Not so. The next test print showed almost perfect but one after that was worse. Not only that but now the magenta and yellow inks were almost done!

When I removed them, sure enough they were nearly empty. So now I have almost no magenta and yellow ink and a cyan cart that appears to be a quarter full but won't print properly. What a mess.

Could I really have used up all of the inks doing 6 or 8 test cycles including test prints? Surely not.

Seems like I now need to order more carts but who from now? Any point in complaining to Choice Stationery Supplies?

Any advice welcome.
