What are the most likely causes of fading on both edges of my prints. I did a test printing of shapes using RGB:FFFF00, FF00FF, 00FFFF, and 000000, which I believe selectively prints from my Yellow, Magenta, Cyan, and black cartridges. They each show the same result, and each has supplies of at least 30%, so I don't think this is a toner issue.
I did the setup/cleaning page action, with no improvement.
I just don't know what actions I can take to diagnose any problem with the unit.
The fading is not unique to the edges, but far more pronounced there. I would upload a scan of an example, but don't see an upload option on this forum's posting interface.
Use the camera icon on the posting to add a picture. Most fading is going to be toner cartridge related. Keep in mind that toner levels are not 100% accurate.
