My custom paper size cannot be found even though I added it to the "User Defined Size" list in the printer driver, or although the Administrator settings are set for a shared printer, the function is disabled on a client computer. The printer is connected to a Windows computer via Bluetooth®.

I turn my printer on but cannot print even though I have already paired the printer with my mobile device using Bluetooth® or connected my device to the same wireless network.

The paper is jammed in the printer.

Paper does not move through the printer even though the motor is running.
