1. NEW TECHNOLOGIES

(1) Dye black ink adoption

In addition to the pigment black ink, dye black ink is adopted in this machine, so that special paper can be

printed in black ink. (For printing plain paper, the pigment black ink is used.)

(2) Automatic Print Head Position Alignment

In this machine, the print head position can be aligned automatically by operating the buttons on the

operation panel and operating from the driver utility.

This is the function to detect the reflection density at the print head position alignment sensor (the same

sensor as the CD-R position detection sensor) and appropriately set the print head position alignment by

scanning the print pattern shown below.

The folloings are detected during the automatic print head position alignment. If an error is detected,

<AUTO HEAD ALIGN ERROR> (LCD message) is displayed.

1) Detecting Paper Size

- Detecting Paper Width (an error is detected if the paper width is too short.)

- Detecting Paper Length (an error is detected if the length is shorter than A4/LTR.)

2) Detecting Print Failure due to no ink ejected

- Detecting Ink Ejecting Status (an error is detected if no ink is ejected.)
