No power

Issue description

If the printer does not power on, or if the control panel is blank, it could be a problem with the Low Voltage Power Supply or with the System Board itself.

Note:  While this issue often requires service, it may be temporary and capable of resolution without assistance from Lexmark Technical Support.

Solution

1. Power off the printer.



2. Power on the printer again and listen to it for one minute. The printer normally goes through a short warm-up sequence where it sounds as though it is going to print out a page.

   Note:  If the printer's control panel is blank but you hear the printer power up as normal, try printing a page from the computer. If the page prints, the printer is still receiving power. However, the control panel is not functioning and will likely need to be replaced (please The Operator Panel Display Is Blank on the Lexmark CS310, CS410, CS510, CX310, CX410, and CX510 for further instructions).



3. Clean dust or any other build-up from the printer’s power cord. If the power cord is damaged, it will need replacement, which will require a service action on the printer. Please contact a local authorized service center or Lexmark Technical Support.

   Note:  If printer's power cord is plugged into a power strips, surge protectors, extension cords and uninterrupted power supplies (UPS), unplug it and connect it directly to a grounded wall outlet. Some of these devices can interfere with consistent electrical flow and cause the printer to fail to power up properly. This is true even if the printer has worked on this surge device previously. If this is not possible, confirm that the power strip is switched on and functioning correctly.



4. If the printer still fails to power up, verify that the wall outlet is working properly by connecting another device to it to see whether it receives power, or try another grounded outlet.



5. If the printer still fails to power up, verify that the Green LED on the front of the printer is still on and the Main Fan is spinning.

   Note:  If the Green LED is ON and Main Fan is running during power-up sequence, the control panel is not functioning and will likely need to be replaced (please Blank Operator Panel with a Functioning Green LED on the Lexmark CS310, CS410, CS510, CX310, CX410, and CX510 for further instructions).
