Note:
Do not bump the carriage or gantry as this can cause dropouts in the printhead nozzles.
A hard bump can break the meniscus vacuum in the ink lines and thus allow air into
the lines, which blocks the nozzle until a purge is performed. Also some procedures,
such as Printhead Maintenance, require that you slide open the door to access the
maintenance station. Do not bang the door hard when you close it after maintenance.
The following table provides our recommended maintenance schedule. This is a minimum
requirement and some procedures may need to be done with greater frequency. Each of
the procedures is explained in detail in this section in the order of frequency required as
presented in this table.
