Note: Do not bump the carriage or gantry as this can cause dropouts in the
printhead nozzles. A hard bump can break the miniscus vaccum 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 Maintennce, 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.
