Solution • Is the AC Adapter inserted correctly? Check that the AC Adapter is inserted. If it is inserted correctly, try plugging it into another AC power outlet. • Is the cable loose? Check that the cable is connected securely. • Is the DK Roll installed correctly? If not, remove the DK Roll and reinstall it. • Is there enough roll remaining? Check that there is enough roll remaining. • Is the DK Roll Compartment Cover open? Check that the DK Roll Compartment Cover is closed. • Has a print error or transmission error occurred? Turn off the Label Printer and then turn it on again. If there is still a problem, contact your Brother dealer. • If the Label Printer is connected via a USB hub, try connecting it directly to the computer. If not, try connecting it to another USB Port. • If using P-touch Editor, select the DK Roll size in [Paper Type] (Windows) / [Print Media] (Mac) drop-down list. • Is the correct port selected? Check that the correct port is selected from the "Print to the following port" list in the Printer Properties dialog box. • Is the Label Printer in cooling mode (the Status LED is flashing in orange)? Wait until the Status LED stops flashing and then try printing again. • Contact Brother Customer Service. • Check that the Label Output Slot is not blocked. • Check that the DK Roll is set correctly by removing the DK Roll and reinstalling it. • Ensure that the DK Roll Compartment Cover is closed correctly. • If a cutter error occurs, keep the DK Roll Compartment Cover closed and press the Power ( ) Button. The cutter moves back to the normal position and the Label Printer turns off automatically. After the Label Printer is Off, check the Label Output Slot and remove any jammed labels. There are three ways to restart: • Turn Off the Label Printer and then turn it back ON. • Disconnect and then reconnect the USB Cable while the Label Printer is On. • Launch P-touch Editor Lite from My Computer.
