1.4.2 Print drive method

The head can be driven in one of the following six drive methods: 180 x 180 dpi (large

dot), 360 x 360 dpi (large dot), 360 x 360 dpi (multi-drop drive), 360 x 360 dpi (large-

large dot), 720 x 720 dpi (small dot), and 1440 x 720 dpi (small dot) with the drive

method differing depending on whether printing is in the forward or reverse direction.

The Block ENABLE, Even/Odd ENABLE, and Heat Select signals are used to select

the heater(s) to turn on in the head nozzles.

Note that the head type (Black BJ cartridge, Color BJ cartridge or Photo BJ cartridge)

does not influence the type of print drive method.

a) 360 x 360 dpi (multi-drop drive, forward direction) control mode

In the multi-drop control mode, two nozzles 8 nozzles apart are driven (one large

drop driven and the other small drop driven) to print the large and small dots at

1/360-inch intervals.

1) Depending on the Odd/Even and Block ENABLE signals, nozzles No. 8 and No.

16, 8 nozzles apart, selected, using the Heat Select signals, nozzle No. 8 will be

heated by the large heater, and No. 16 by the small heater.

2) The nozzles next to No. 16 and No. 8, No. 15 and No. 7, will be heated similarly.

3) After nozzles No. 8 through No.1 have been heated by the large heater and

nozzles No. 16 through No. 9 by the small heater, No. 8 through No. 1 will be

heated by small heater and No. 16 through No. 9 by the large heater.
