Power on/off the printer by pressing the / (Standby/Home) button of the printer.
• Do not repeatedly power on/off the printer.
• If you power the main power source off and then on again quickly, the printer may not
be powered on because it is still in the powering off process. In such a case, press the
/ (Standby/Home) button to power on the printer.
• Do not power off the printer during operation, such as when printing or updating. Doing
so could cause a malfunction of the printer.
• Do not disconnect the power cord until the powering off process is completed on the
printer.
• An incorrect power on/off operation may damage the printer settings. In such a case,
the printer settings are reset to their initial values. It is always recommended to use
the power button to allow proper shutdown of the printer and ensure changes made to
menu settings are saved appropriately.
