The error code I am getting is B504, which I believe is the new 5040. I have followed the directions from the error message but cannot resolve the issue.&nbsp; I have unplugged the printer several time and cleared all the print jobs.&nbsp; I have also checked the ink cartridges to make sure that they are properly seated.&nbsp; Every time I turn my printer back on, it tries to print and gives me the same error message.&nbsp; I have instructed it to clean print head but error message overrides it.&nbsp; Is there anything else I can do?</SPAN></P> Mon, 26 Jan 2026 19:41:16 GMT ldrun417 2026-01-26T19:41:16Z https://community.usa.canon.com/t5/Office-Printers/MAXIFY-MB2720-Printer-Error-5040/m-p/584124#M30549 <P><SPAN>I am having a printer error on my Canon Maxify MB 2720 all in one printer.
