I have not used the e-mark (create) for a while. What do I need to consider?

To ensure a steady print quality, the e-mark (create) must be used on a regular basis (once a week), or at least clean the print head once a week. Find more details on print head cleaning here: When and how do I have to clean the print head of the e-mark?

You might need to charge your e-mark after longer downtime due to self discharge, which is common for battery driven electronic devices.
