1.5.4 Input Tray Paper Setting
If KEY 1 is pressed in user settings mode while the print density value is being displayed, the current input tray
setting for the type of paper will be displayed as shown below.
This setting is also assigned to non-volatile memory code A. (Refer to 1.8.3 List of Non-volatile Codes.)
If KEY 0 is pressed, the type of paper can be
[1]
changed and this setting is entered in the non-
volatile memory at the same time.

Caution:
Since the printer's paper setting is controlled by the host, the printer's and host's paper settings will
always be the same. If the printer's setting is changed and is no longer the same as the host's setting,
the printer's setting will automatically change to match the host's setting.
1.6 Test Print Mode
1.6.1 Function
This mode enables the printer's built-in test pattern (self-test pattern) to be printed at maximum speed.
The self-test pattern is shown below.
* 1 The straight lines perpendicular to the direction that the paper is fed into the printer
A black line with a width of one dot is printed at 128 dots.
(However, the straight line at the bottom of the page is not printed 128 dots from the previous line.)
* 2 The straight lines in the direction that the paper is fed into the printer
A black line with a width of about one dot is printed at about 128 dots.
(However, the straight line at the right of the page is not printed 128 dots from the previous line.)
•
About 1 dot: Since the horizontal and vertical widths of the dot is converted in the clock of the MCU PWB's
circuit, the actual distance between the lines is not 127 dots.
