2.1.2 Print Driving

0012-6309

During printing, print signals and control signals are issued to the printhead via the carriage relay PCB and Head relay PCB in order to discharge ink from the

nozzles.

On a printhead, six arrays of nozzles are provided in six arrays in a staggered pattern.

This printer uses a pair of printheads.

(The Y, PC, C, PGy, Gy, MBk, PM, M, Bk, R, G, B nozzles are mounted in this order from the left.)

Even-numbered nozzle data and odd-numbered nozzle data -- which are print signals -- are sent to each nozzle array in sync with the data sending clock and data

latch pulse timings.

Drive control signals include a Heat Enable signal and a Sub Heat Enable signal. The Heat Enable signal is used to discharge ink from nozzles. The Sub Heat Enable

signal is used to raise the printhead temperature to a suitable value to maintain the ink discharge amount constant.
