At printing, print signals and control signals are output to the printhead via the carriage relay PCB and Head relay PCB to discharge inks from the nozzle assembly.

The printhead six trains of nozzles arranged in a zigzag pattern.

This printer uses only one printhead.

(Installed from left to right: C, M, Y, MBk, MBk and Bk)

Two kinds of print signals are transferred to each nozzle train according to the data transfer clock and the data pulse timing: even-numbered nozzle data and odd-

numbered nozzle data.

Drive control signals fall into two types: heat enable signals and subheat enable signal. The heat enable signal allows inks to be discharged from the nozzles, whereas

the subheat enable signal heats the head to an optimal temperature to keep the rate of ink discharge constant.
