Overview and Specifications
1.1 Overview
The SATO CL408e/CL412e Printers Service Manual provides information for
installing and maintaining CL408e/CL412e Thermal Transfer printers. Step-bystep 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 major differences in the CL408e and the CL412e printers is the resolution of
the head. The CL408e with its 203 dpi head provides an economical labeling
solution for most applications. It can print labels up to 4.1 inches wide. The
CL412e provides a higher print resolution, 305 dpi to give laser-quality printing. It
is useful when higher resolution is needed for detailed graphic images.
The CL Series "e" printers use a subset of the standard SATO Command
Language. The CL408e/CL412e share the same command set, the only
differences are the allowable values representing the print positions on the label.
These values are specified in "dots" and will vary depending upon the resolution
of the printer and the amount of memory available for imaging the label. The
allowable range for each printer is specified in a table for those command codes.
The sections in this manual cover the following:

RIBBON MOTION SENSOR:
This sensor is a motion detector that
signals the printer when the ribbon
supply is turning. This sensor is used
for both the ribbon end and ribbon
near end sensing.
LABEL SENSOR:
Both the "Eye-Mark" (reflective) and Gap
(transmissive) sensors can be adjusted over
a limited range. They are both located in
the label sensor unit. The assembly can be
adjusted by loosening the green sensor
knob located underneath the label transport
assembly and sliding the label sensor unit
to the desired position. The gap sensor can
be adjusted from a minimum of 0.67 in.
(17mm) to a maximum of 2.5 in. (64mm)
and the "Eye-Mark" from a minimum of
0.25 in. (6mm) to a maximum of 2.1 in.

The CL408e/CL412e Operator Panel consists of one two-color (red and green) LED
indicator, two momentary contact switches, two DIP switches (a third is located on the
RS232 interface card), four adjustment potentiometers and one LCD display. All of
these are accessible from the front of the printer, however some are not accessible
unless the front cover is open. They are used to set the printer operating parameters
and to indicate the status of the printer to the operator.

LCD DISPLAY PANEL2 Line x 16 Character LCD display. Used for setting operational
parameters of the printer.
STATUS LEDTwo-color (Red, Green) LED that indicates the following status
conditions.
Green-Illuminated when printer is ready to receive data.
It is turned on and off by toggling the LINE key.
Red-Illuminated when there is a system fault such as an
open print head.
LINE KEYMomentary switch. Pressing this key toggles the printer between
the on-line and off-line mode. When the printer is on-line, it is
ready to receive data from the host. This key acts as a pause
during a print job by taking the printer off-line. It can also be
used as a PAUSE function key to stop label during the printing
process.
FEED KEYMomentary switch. Pressing this key feeds one blank label
through the printer when it is off-line. When the printer is online, there is a user selectable option in the Service Mode (see
page 2-28) to either print a copy of the previously printed label
or feed a blank label. The default is to feed a blank label.
POTENTIOMETERS

adjust amount of back/forward feed for dispenser/cutter/tear-off
bar position (+/- 3.75mm).
PITCHLocated behind the Front Access Door. Potentiometer is used to
adjust home position of the label (+/- 3.75mm). Affects stop
position of label feed, print position and dispense position.

THRESHOLD
adjust the sensing level of the Label Taken Sensor. Active only
when the Label Dispense option is installed.

operational parameters of the printer. DSW1 is used to set the
RS232 parameters and is located on the RS232 interface board if
installed in your printer.
OPTIONALLocated behind the Front Access Door. This connector is used for
CONNECTOR
the cutter and dispenser optional accessories.
LABEL TAKEN LEDLocated behind the Front Access Door. This LED is illiminated
when a label is not present in the Label Taken Sensor. If it is not
illuminated, a label has been detected in the sensor and printing
will be inhibited until it is removed. This LED is active only
when the Label Dispense option is installed.

1.6 Installation Considerations
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, 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.
Warm temperatures which can cause electrical problems within the printer. (See
Two DIP switches (DSW2 & DSW3) are located inside the Front Access Door.
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
DIP SWITCHES
In addition, a third DIP switch (DSW1) is located on the optional 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 effect until the power is cycled.

Dip Switch Selections
All switches are placed in the Off position (default) except Receive Buffer for shipping.
This will result in the following operating configuration:
(1) Applicable only if an RS232 Interface Card is installed in the printer.
Software Default Settings - The printer stores any software settings upon receipt from
the host and uses them until they are again changed by receipt of a command
containing a new setting. These settings are stored in non-volatile memory and are
not affected by powering the printer off. The printer may be reset to use the default
software settings by depressing the LINE and FEED keys simultaneously while
powering the printer on. You will be asked to confirm that you want the printer
default settings by selecting either YES or NO by using the LINE key to step the
underline cursor to the desired setting. If you select YES and press the FEED key, the
following default configuration will be stored:

Once the default operation is completed, a DEFAULT SETTING COMPLETED
message will be displayed on the LCD panel and a single "beep" will be heard. The
printer should be powered off while this message is being displayed. This saves the
default settings in the EEPROM where they will be automatically loaded the next time
the printer is powered on.

2.3 LCD Panel Configuration
The LCD Panel on the CL408e/CL412e is used in conjunction with the LINE and FEED
switches by the operator to manually enter printer configuration settings. Many of the
settings can also be controlled via software commands and in the case of conflict between
software and control panel settings, the printer will always use the last valid setting. If you
load a label job that includes software settings and then enter a new setting via the LCD
Panel, the manually set values will be used by the printer. If you set the values manually
and then download a job with software settings, the software settings will be used.
There are 7 configuration and operation modes you can access from the LCD panel. To
enter the desired mode, the KEY SEQUENCE combination listed in the table below must be
performed. The initial LCD display message is shown for each mode.

The label pitch is the distance from the leading edge (the edge that comes out of the

the label can be adjusted relative to the print head +/- 49mm in increments of 1mm.
Once the position is set, it can be fine adjusted +/- 3.75mm using the PITCH
potentiometer on the adjustment panel.
STEPPROCEDURE
1.The underline cursor will initially be positioned underneath the Pitch
Direction setting. Use the LINE key to step the underline to either the
positive (+) or negative (-) selection. A position selection moves the
leading edge of the label forward (away from the print head) while a
negative selection moves the leading edge of the label back into the
