Printer Parts (CS2436-8)
Important
Never disconnect the printer's power supply or unplug it during a print job. This may damage the printer.
1.
Make sure no print jobs are in progress.
If the Message Lamp is flashing, check the message on the Display Screen and take action as necessary. (See
"Error Messages.")
If the Data Lamp is flashing, the printer is receiving a print job. Turn off the printer only after printing is finished.
2.
Hold down the Power button for more than a second.
After "Shut Down.. Please Wait.." is shown on the Display Screen, the printer shuts off.
