1.4.5 Printer Adjustment Mode

The Stylus 1500 allows the user to adjust the printing direction and head gap without a special program. The following list shows the adjustments for this printer in order:

Pattern 1 Uni-D adjustment at 400 cps

Pattern 2 Bi-D adjustment at 100 cps

Pattern 3 Bi-D adjustment at 200 cps

Pattern 4 Bi-D adjustment at 400 cps

Pattern 5 Head gap adjustment (for the black and color printheads in the carriage movement direction at 100 cps)*

Pattern 6 Head gap adjustment (for the black and color printheads in the carriage movement direction at 200 cps)*

Pattern 7 Head gap adjustment (for the black and color printheads in the paper feed direction)*

* These adjustments are performed only when the color upgrade kit is installed in the printer. Adjustment Method

Use the following steps to perform the adjustments:

1. Hold down the Pause button while turning on the power. The printer enters adjustment mode. "Using this mode" and the pattern 1 are printed.

2. Select the number of the most closely aligned columns by pressing the Alt button.

The black Ink Out, color Ink Out, and Paper Out LEDs show the line number currently selected. This selection advances once each time the Alt button is pressed, and the three LEDs change their combination of On /Off / Blinking to indicate the selection.

3. Specify the selected number by pressing the Pause button. The selected number is set, and the next pattern is printed.

Note: The last panel settings are kept after software initialization.

3. Panel Initialization

Panel initialization is performed by pressing the Load/Eject button while holding down the Alt button. The following functions are executed:
