I have a MF644CDW printer and have installed some brand new high output canon OEM carts. When print color test pages, the amount of color dropped on the page is a fraction of what is needed to make the output suitable. I am attempting to do image quality tests (gradiation, correction, etc), and none of the tests complete, in fact, these tests fail before the printer actually prints a page to scan, when that is required. The toner carts have only been used to print test pages so far. Black is the only color that prints correctly. I have reset the printer to factory settings, cleaned the internals, put other toner carts in, and none of this has helped. When I spoke to support, they told me I could take it to a repair shop (no such thing has existed in my town for more than a decade), and had no alternatives to test or otherwise troubleshoot the issue. I wish I had done something when this stated about 4 months ago, because the unit would have still been in warranty, but this is where I am. Is there any guidance or additional troubleshooting/testing that I might be able to do to get the system to complete the tests? All printing functions work, the cart springs and other features appear to be in place.
