Why Is The Display Blinking While It Is Powered?

Loose or damaged cables. Make sure that all of the cables connecting the printer to the power supply, display, and computer are properly connected and in good condition.

Faulty power supply. If the power supply is faulty, it can cause the display to blink. Try replacing the power supply.

Corrupted firmware. The firmware is the software that controls the printer's operation. If the firmware is corrupted, it can cause the display to blink. Try updating the firmware.

Hardware failure. If the display itself is faulty, it can cause it to blink. In this case, you will need to replace the display.

To troubleshoot the issue, you can try the following:

Check the cables connecting the printer to the power supply, display, and computer. Make sure that they are properly connected and in good condition.

Try a different power outlet.

Update the firmware. You can download the firmware from the Sharp website.

If the display is still blinking, you may need to replace it.

If you are not comfortable troubleshooting the issue yourself, you can contact Sharp support for assistance.

Here are some additional things to check if the above solutions do not resolve the issue:

Make sure that the printer is turned on and that the power cord is properly plugged in.

Try restarting the printer.

If you are using a USB cable to connect the printer to the computer, try using a different USB cable.

If you are using a wireless connection, try connecting the printer to the computer using a wired connection.

If you are still having problems, contact Sharp support for further assistance.
