Xitron PCA


Xitron's hardware interface for the HP® FI-1000 “Bar in a Box” Printhead is Compatible with Navigator DFE


The Xitron PCA (HP’s terminology ‘Printed Circuit Assembly’) is pin-compatible with the hardware reference design from HP®. At a base level it controls reset, power on, ink door state, and a special 1-watt power required by the power supply. It also passes TOF (Top of Form) signals and encoder pulses through to the HP® Main PCA. The reference design had two options each for TOF and encoder. The Xitron PCA supports the 3-pin TOF connector (J2 on the HP® PCA) and the 6-pin encoder connector (J7).
