Hi all. I am having issues printing in black or colour , as follows : Black - the printer goes thru the motions, but just a blank page comes out Colour - it prints the picure, but the colours are all distorted These are good cartridges, and have been tried in another printer. I have tried a test print. It just a red triangle at the top , then 3 rows of small blue squeares at the bottom I have selected the option to clean the print cartridges. It then prints out a row of letters clearly , but in Grey. It then prints 2 rows of colours . Theses are are a mix of colours , yellow , blue, green, purple Thanks for any help.
