2. Print drive timing

Each printhead houses 12 trains of nozzles, which share the same data transfer clock (Hx-CLK) and data latch

pulses (Hx-LT).

Even-numbered nozzle data (Hx-x-DATA-x-EV), odd-numbered nozzle data (Hx-x-DATA-x-OD) and the

Heat Enable (Hx-x-HE-x) signal are generated for each nozzle train and controlled individually.

Printing is carried out in two ways through reciprocating motion of the carriage.

An encoder sensor mounted on the carriage generates a 150-dpi-pitched linear scale detection signal

(ENCODER_A) and a signal (ENCODER_B) shifted 120 degrees in phase. The direction of carriage motion

is detected from the status of the ENCODER_B signal relative to the leading edge of the ENCODER_A signal.

The printhead is driven using a 2400-dpi timing signal (internal signal), which is generated by dividing the

ENCODER_A signal detected at the 150 dpi timing into 16 equal sections.

Printing in the forward direction is triggered at the leading edge of the detection signal (ENCODER_A).

Printing in the backward direction is carried out the same way as printing in the forward direction but at the

trailing edge of the detection signal (ENCODER_A), when the order of heated nozzles is reversed depending

on the sequence of transfer of even-numbered nozzle data and odd-numbered nozzle data.
