SATO M-10e TT/DT Printers Service Manual
Section 2. Configuration
LCD Panel — Service Mode
The Service Mode allows the operator to set up basic operation parameters of the printer. The
Service Mode is entered from the Advanced Mode/Card Mode.
STEP PROCEDURE
1. From the Advanced Mode press the key once to switch to the Service
Mode.
2. Press the ENTER key to advance to the first selection.

The M10e printers determine the location of the leading edge of the label by measuring the
difference between light levels when it sees either a label edge or a black “EYE” mark. This
adjustment allows you to manually set the threshold voltage level, between the maximum and
minimum light levels. DIP switch DSW2-2 selects the sensor type. If DSW2-2 is in the OFF
position, the setting will be for a See-Thru (or Gap) sensor and the LCD will display “GAP” on
the top line along with the current setting. If DSW2-2 is in the ON position, the LCD will
display “EYE” on the top line with its current setting. If the value entered for the bottom line
setting is “0.0V”, then the printer will automatically calculate the setting when the first label is
fed after the printer is powered on or the head is closed. There are some instances where the
automatically calculated value must be adjusted to ensure reliable label feeding, such as when
the backing opacity or the reflectance of the EYE mark varies significantly within a roll of
labels or between label rolls. In these instances the value should be set using the following
procedures.
GAP - When setting the “GAP” threshold, the voltage shown on the top line of the display
must be measured with nothing but the backing in the sensor and then again with a label still
attached to the backing. The formula to be used for setting the threshold is:
(High Voltage Level + Low Voltage Level) x 0.5 = Start Value

STEP PROCEDURE
1. Insert a label still attached to the backing into the sensor and close the
Label Hold-Down. Record the voltage shown on the top line of the
LCD panel. This line should have the message “GAP” on the top line
(DIP switch DSW2-2 = OFF). Make sure the label is all the way under
the sensor.
