Having problems with the printhead on my printer lexmark s405 how do i fix the problem it wont respond to anything

Try to reseat the printhead. Open the cover of the printer > remove the printhead. If the printhead will not go to the center, unplug the printer from the power outlet to turn it off, pull the printhead to the center. Then remove the printhead. Close the cover. Replug the printer to the power source after at least 10 seconds. Re-insert the printhead when prompted.
If problem continues, updating the firmware for your printer will help fix the issue. Turn off the printer and remove the printhead from the printer again. Close the cover. Replug to the power source after 10 seconds. It will then ask you to "Open Cover to Install the Printhead". Press the Cancel (Red X) button. It should take you back to the "Copy" menu. Proceed with the firmware update. Just go to http://bit.ly/s405fw to download and install the update. Once the update is done, reinsert the printhead by following the prompt on the screen of your printer.
