My printer just will not properly print anything. Text or images it doesn't matter. If I try to print out black text, it simply does not appear. If I try a dark blue it comes out as a red, crappy color. Print a picturea nd it comes out all red and purple and streaky. I very rarely use my printer. Last time I used it was probably 3 to 5 months ago. The cartridges are both about 3/4 full(according to the printer software). My only thought is ink dried up or dried up on the printer portions so it won't put it down. Lexmark's troublershooting software is useless. Printer is a Lexmark Z600. Help if you can please guys, I have to print something for class tomorrow.
