The cartridge was delivered quickly after being ordered which was the good thing about it. However when it was loaded into the printer evrything was printed in blue and green or yellowy green. After trying to print several pages, all with the same result,I e-mailed IJT about the problem. I received the following advice "It needs to be in an upright position as it would be in the printer and not used for at least twelve hours before use. If it is still a problem, stand it upright in 1/4 inch luke warm tap water, wipe the printhead and rear contracts dry and reinsert into the printer. Print off four or five test pages and this should resolve the issue." After I had left it in the printer for five days I followed the rather bizarre- sounding advice and of course, no difference at all. I e-mailed IJT straight away telling them I would return the cartridge and expect a refund. I have not had a reply to that so have returned it today and hope I shall receive a refund. My advice is...buy from somewhere else!
