*1: Forward order refers to serial data in the same order as the image being printed. Reverse order refers to serial data in the reverse order to the image being printed.

*2: The ODDE and EVENE signals from the logic board are input to the black head and ink optimizer head, and to the color head and photo head, in reverse order.

The black head and ink optimizer head, and the color head and photo head, are the same BJ heads arranged symmetrically about a center point. The nozzle arrays are therefore reversed.

For this reason, the order in which BLOCK1 to 6 are output, the arrangement of IDATA, and the connections of ODDE and EVENE are reversed in order to align the ejection of ink at the print media.

In the BC-60 and BC-61/BC-62 Photo, the odd nozzles and even nozzles correspond because of the arrangement of the nozzles in respect to the print media. Therefore, the ODDE and EVENE signal connections are reversed to align the ejection of ink at the print media.
