System Power-Up Sequence
Use the power-up sequence timing chart to troubleshoot failures that occur during the
power-on sequence. The chart provides typical timing of mechanical events that occur
relative to power-on, assuming the printer is cold and was shutdown properly. The
actual timing will vary if the printhead is not parked or if the printer is located in
extremely hot or cold environments.
Note
Warm printers reach “Ready To Print” in about 2 minutes while cold printers
require up to 12 minutes. Only cold systems require Steps 18-21 below for
cleaning the printhead. A cold system is defined by the printhead temperature
being below 95 - 100
