I was printing a banner and everything went fine. I started printing another banner just like the first and suddenly what supposed to be printed red started printing yellow. I checked my ink and the only one I found empty was the magenta, but the machine didn't stop or beep for a cartridge change. I changed the magenta anyway, it was so low it didn't even register on the machine for ink remaining. Since I changed it, I did a head cleaning, both by machine and manually and ran small versions of the second banner and it's still printing yellow instead of red. Any ideas?
