The SATO M-8485Se Service Manual provides information for installing and
maintaining M-8485Se Thermal Transfer Print ngines. Step-by-step
maintenance instructions are included in this manual with typical problems and
solutions. It is recommended that you become familiar with each section in this
manual before installing and maintaining the printer.
The SATO M-8485Se Print ngines are designed to be integrated into high
performance on-site labeling systems. All printer parameters are user
programmable, using front panel controls and DIP switches. All popular bar
codes and 14 human-readable fonts, including a vector font, are resident in
memory providing literally thousands of type styles and sizes.
The M-8485Se with its 203 dpi head provides an economical labeling solution
for most applications. It will print on labels from 1 inch wide x .25 inches long
to 5.25 inches wide x 14 inches long using internal memory. Labels up to 5.25
inches wide x 49.2 inches long can be printed by installing a PCMCIA memory
card option. The maximum print width is 5.0 inches.

ADJUST SLOT SENSOR POSITION
SCREWS
The label gap (transmissive) sensor can be positioned over a limited range. The movable
sensor assembly is mounted on the Label Hold Down and is held in position by two screws.
To adjust the position of the sensor, both screws must be loosened and the sensor moved to
the desired position in the slot and then the screws retightened. Adjustments to compensate
for different liner opacity are done with the LCD panel.

Adjusting the Label Sensor
The M-8485Se printers can position labels using either a label gap (transmissive) or an " ye-
Mark" (reflective) sensor. The sensor used is selected by DSW2-2. The gap sensor position
can be adjusted over a limited range. In addition, the signals from the sensors can be
adjusted using the LCD panel to compensate for different liner opacities and/or " ye-Mark"
reflectance values.

1.10 Installation Considerations
Use only SATO thermal transfer ribbons which were formulated expressly for use in all
SATO printers. Use of other than approved ribbons may result unsatisfactory print quality
and/or damage to the print head and may void your warranty.
Printer operation can be affected by the printer environment. The location of the printer
should be free from dust, humidity and sudden vibrations. To obtain optimum results from
the printer module, avoid locations influenced by:
 Direct or bright sunlight since bright light will make the label sensor less responsive and
may cause the label to be sensed incorrectly.
 xcessive warm or cold temperatures can cause electrical problems within the printer.
(See Section 3- Specifications).

Configuration
2.1 Dip Switch Settings
2
Section
Two DIP switches (DSW2 & DSW3) are located inside the cover. These switches
can be used to set:
• Thermal transfer or direct thermal mode
• Head Check Mode
• Hex Dump Mode
• Label sensor enable/disable
• Single Job or Multi-Job Receive Buffer
• Operation Mode
In addition, a third DIP switch (DSW ) is located on the RS232 Serial Adapter
card and is used to set the RS232C transmit/receive parameters.
DSW1
Each switch is an eight section toggle switch. The On position is always to the
top. To set the switches, first power the unit Off, then position the DIP switches.
Finally after placing the switches in the desired positions, power the printer back
on. The switch settings are read by the printer electronics during the power-up
sequence. They will not become effective until the power is cycled.
