So, my printer suddenly started to print solid completely black prints no matter what I add to the queue and print. Literally solid black sheets of paper. Any idea what the issue could be, or am I completely out of luck. To see if it was a toner cartridge issue I replaced the toner...no effect, continues to print solid black prints.</P><P>Thank you!</P> Tue, 07 Oct 2025 02:44:00 GMT 2thVet 2025-10-07T02:44:00Z https://community.usa.canon.com/t5/Office-Printers/ImageCLASS-LBP674CDW-printing-completely-black-sheets/m-p/570465#M29887 <P>Hello, I did a community search for prior posts on similar topics; I saw one that had nearly the same subject, and was never answered....</P><P>Before I physically send in the printer for service, I was hoping there might be an easy fix?
