I've had this printer (Pixma MG5320) for about a year and a half now and recently noticed a problem with it. I have been doing a lot of black and white photography lately (both digital and analog), and every black and white photo I print has some color fo it. For instance I printed out a black and white digital picture I took recently that I edited using Nik's Silver Efex Pro. Instead of the picture coming out black and white, it has an orange/red hue to it throughout the image, yet on my monitor it is void of all colors (except shades of black and white of course). A few months ago I tried to print another picture, and it had a blueish/green hue printed throughout the picture as well.
I am printing all these photos via Photoshop, and even went into the settings to click on "grayscale printing" but the problem still persists. The printer does this with both brand new ink cartridges and ones that have been used before. I can't figure out if there is some odd setting in Photoshop that I may have accidently messed around with (though there really shouldn't be), or if it's an issue with the printer itself. If I print a color photo, all the colors seem about right and I don't notice an off hue on any of them.
Does anyone know what could cause this? I am just trying to troubleshoot the whole ordeal because it's gotten to the point where printing b&w photos is not in question until I figure this issue out.
