We do not recommend frequent unplugging and re-plugging of the machine and/or leaving the machine unplugged for extended periods of time.
To maintain premium print quality, our product is designed to automatically clean the print head periodically. When the machine is unplugged, it will not complete the periodic cleanings needed to ensure ink does not dry in the print head and may cause poor print quality.
We recommend using the Power On/Off button to power down the machine. Using the Power On/Off button allows minimal power to the machine ensuring periodic cleanings of the print head occur only when necessary.
- Cleaning the print head consumes ink. Cleaning too often uses ink unnecessarily.
- DO NOT touch the print head. Touching the print head may cause permanent damage and may void the print head's warranty.
