I'm on Mac OS 10.14.5, with printer driver 126.96.36.199. Printing from Photoshop CS 6. I've had no problems for several years with color until now.
I noticed smudging and green tones in a red zone on a photo print. I tried a test print which showed only a little magenta in the block. Several cleanings and 2 deep cleanings later, the magenta block remains empty on test prints. Printer utility is now telling me magenta is empty ( it is actually brand new) but when I open the top of the printer, the only cartridge flashing is pale magenta. (also new). All inks are in their correct slots.
Now unable to print anything as it insists I need a new magenta cartridge. Suggestions?
