I have a Epson Workforce WF-3620, it is now 14 months old. Up til now it gave me reasonable good colour prints. I have noticed over the last couple of days it has been giving me Pasquale colours. Today I printed my favourite BRIGHT YELLOW rose, and it came out pink. I then printed my favourite BRIGHT RED autumn leaves and it came out BRIGHT RED...... I went on to print out a green stem with some green aphids on it and they came out GREY. I have run all the maintenance checks. I have changed some cartridges that were a little low. I am using Epson Ink and Epson glossy paper. Any ideas before I ring Epson on Monday morning.
