I searched the Support Page and found this article on the printer not powering up that may help you troubleshoot the issue.
After I have changed the blogged waste-toner tubes, the printer is completely dead.
From a spare printer I've changed the power supply also, but to no avail. Printer's still dead. There's no noise and thus, the display does'n show anything.
Got any idea what else might be wrong, or, maybe could send a printer's blow up and a circuid diagram?
kindly ask by
