Processing apparatus for individual items, having an inkjet print head, and an activation method therefor

An activation method for operating a processing apparatus that processes individual items, said processing apparatus comprising an inkjet print head, said activation method comprising:

• from a control processor, providing control signals to a drive motor arrangement in order to operate a transport mechanism to transport individual items in the x-direction of a Cartesian coordinate system past said inkjet print head in a printing position so as to execute a printing operation with said inkjet print head on each individual item;
• from said control processor, providing said control signals to said drive motor arrangement so as to move said inkjet print head in the y-direction of the Cartesian coordinate system into a first position selected from the group consisting of an exchange position at which an exchange operation is implemented to exchange an ink cartridge for said inkjet print head, said printing position, a cleaning position in order to implement a cleaning operation of said inkjet print head, and a sealing position in order to seal said inkjet print head;
• and
• from said control processor, providing said control signals to said drive motor arrangement to also move said inkjet print head vertically, in the z-direction of said Cartesian coordinate system from said exchange position or said sealing position, into at least one second position selected from the group consisting of said printing position and said cleaning position.
