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:
· Section 1. Overview and Specifications
· Section 2. Configuration
· Section 3. Interface Specifications
· Section 4. Electrical Checks and Adjustments
· Section 5. Mechanical Adjustments
· Section 6. Replacement Procedures

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.
(53mm) from the fixed position, "inside

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
Section 1-8 Environment.

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.

Print Offset
Print offset
v:+0000 H:+000
Since the printer moves the label in discrete steps equal to the size of the print dot, the
units of measure for Vertical and Horizontal Offset distance is dots.
Vertical Offset is the distance down from the leading edge in dots (the edge of the
label that comes out of the printer first) to the first vertical print position. A positive
setting moves the first print position down the length of the label while making it
negative moves it up the length of the label. The maximum value that can be set is 823
dots.
Horizontal Offset is the distance that the label image is shifted either to the right or
left on the label. For a positive setting the image is shifted to the left (towards the inside
edge of the label). For a negative setting the image the image is shifted to the right
(towards the outside edge of the label). This setting changes the base reference point for
all subsequent label jobs. The effect is identical to the <ESC>A3 Base Reference point
command. The maximum value that can be set is 1424 dots.
STEP PROCEDURE
1. Use the LINE key to step the first digit of the counter to the desired setting.
The display will increment one step each time the LINE key is pressed.

Gap [X.XV]
gap [x.xv]
Input [X.XV}
input [x.xv]
The CL408/CL412e printers determine the location of the leading edge of the label by
measuring the difference between light levels when it sees either a label gap 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 [X.XV]
Input [X.XV}
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.
2. Strip the label from the backing and insert the backing strip under the
sensor and close the Label Lid. Record the voltage shown on the top
line of the LCD panel. The voltage ranges measured should be within
the following range.
gap [x.xv]
input [x.xv]
Backing without label = 0.5V or less
Backing with label = 1.0V above the low value
If the measured values are outside this range, you may have trouble
finding a value that will work properly under all conditions. If this is
the case, a higher quality label may be needed to get adequate
performance.
3. Calculate the starting point voltage using the formula.
4. Use the LINE key to step the counter to the desired setting. The
display will increment one step for each time the LINE key is pressed.
If the LINE key is held down for more than two seconds, it will
automatically go into the fast scroll mode. The reading will advance
to a setting of 3.3 (the maximum voltage) after which it will
automatically wrap and start at "0.0" again. If a value of "0.0" is set,
the printer will automatically set the level each time the printer is
powered on with labels loaded or the head is closed.
5. Once the setting is correct, pressing the FEED key will accept the
setting and advance to the Online Feed display.

Eye [X.XV]
Input [X.XV}
EYE - When setting the "EYE" threshold, the voltage must be measured with nothing but
the label under the sensor and then again with the printed "eye" mark under the sensor.
The formula to be used for this is:
(High Voltage Level + Low Voltage Level) x 0.5 = Start Value
STEP PROCEDURE
1. Insert a label into the sensor and close the Label Hold-Down. Make
sure the printed "eye" mark in not under the sensor. Record the
voltage shown on the top line of the LCD panel. This line should have
the message "EYE" on the top line (DIP switch DSW2-2 = ON).
2. Now pull the label forward until the "eye" mark is positioned under
the sensor (the voltage reading shown on the top line of LCD panel).
The voltage ranges measured should be within the following ranges:
eye [x.xv]
input [x.xv]
Label Only = 0.3 - 0.5V
Eye-mark = Equal to or greater than 1.2V
above the low value.
If the measured values are outside this range, you may have trouble
finding a value that will work properly under all conditions. If this is
the case, a higher quality label may be needed to get adequate
performance.
3. Calculate the starting point voltage using the formula.
4. Use the LINE key to step the counter to the desired setting. The
display will increment one step for each time the LINE key is pressed.

3.2 Interface Types
The parallel interface for CL408e/CL412e printers is a high speed, bi-directional parallel
interface that conforms to the IEEE 1284 specification. (ECP mode on some computers).
The interface is also compatible with the older Centronics parallel interface standard. If
it does not detect the correct IEEE 1284 signals in the interface connection, it will
automatically operate in the standard Centronics mode which is much slower. To use
the IEEE 1284 parallel interface to its fullest capability requires that the host also have
an IEEE 1284 compatible interface and that the two be connected with a cable that
meets the IEEE 1284 specification. If either of these two are not present, the data rate is
severely compromised.

Section 3. Interface Specifications
Interface Types
In order to provide flexibility in communicating with a variety of host computer systems,
CL408e/412e printers use a Plug-In Interface Module. The IEEE1284 Interface module is
shipped with the printer unless another interface type is specified at the time of the order.
The other interfaces available are a high speed (to 57.6K bps) serial interface, an Ethernet
interface or an optional Universal Serial Bus (USB) interface.
The Parallel interface will probably be the most useful in communicating with IBM PCs and
compatibles. The RS232C Serial interface allows connectivity to a number of other hosts.
The USB interface allows the printer to be connected to a computer that supports
peripherals attached to a USB bus.
WARNING: Never connect or disconnect interface cables (or use a switch box) with power
applied to either the host or the printer. This may cause damage to the interface circuitry in
the printer/host and is not covered warranty.

3.3 The Receive Buffer
The CL408e/CL412e printers have the ability to receive a data stream from the host in
one of two ways. The receive buffer may be configured to accept one print job at a
time or multiple print jobs. The single job print buffer is generally used by software
programs that wish to maintain control of the job print queue so that it can move a
high priority job in front of ones of lesser importance. The multiple job buffer on the
other hand prints all jobs in the order they are received by the printer and the order of
printing cannot be changed.
Single Job Buffer
The printer receives and prints one job at a time. Each job must not exceed 2.95MB.
Multi Job Buffer
The printer is able to continuously receive print jobs, compiling and printing other jobs
at the same time. It acts much like a "print buffer" ot maximize the performance of the
host and the printer.
When using the RS232 Serial interface, the Multi Job Buffer uses either the Ready/
Busy with DTR (pin 20) or X-On/X-Off flow control protocols. See these sections
for more details. With an empty receiving buffer, the status of DTR is "high" (or an X-
On status if using X-On/X-Off), meaning the printer is ready to receive data. When
the receive buffer is holding 2.0MB of data (1MB from being full), DTR will go "low"
(or an X-Off is sent) indicating the printer can no longer receive data. This condition
is called "Buffer Near Full"
0
DTR High
or
X-On
2.0 MB 2.95MB
Buffer Near Full

or
X-Off
The receiving buffer will not be able to receive more data again until a "Buffer Available"
condition occurs. This takes place when the receiving buffer has emptied so that only 1MB
bytes of data are being held (2.0MB bytes from being full). At this time, DTR will go "high"
or an X-On is sent to tell the host that it can again receive data.

All printer error conditions (i.e., label out, ribbon out) will cause the printer to go busy
(DTR "low" or X-Off) until the problem is corrected and the printer is placed online. The
printer will also be busy if taken offline from the front panel.
3.4 IEEE 1284 Parallel Interface
The parallel interface for the CL408e/CL412e printers is a Plug-In Interface Module that
can be installed by the user. It conforms to the IEEE 1284 specification. It will
automatically detect the IEEE 1284 signals and operate in the high speed mode. If it
does not detect the IEEE 1284 signals, it will operate in the standard Centronics mode,
which is significantly slower. For this reason, an interface cable and host interface
conforming to the IEEE 1284 specification must be present to fully utilize the speed
capabilities. This interface also operates bi-directionally and can report the status of the
printer back to the host.

Ready/Busy Flow Control
Ready/Busy is the hardware flow control for the serial interface on the CL408e/CL412e
printers. By raising/lowering the voltage level on Pin 20 of the RS232 port, the printer
notifies the host when it is ready to receive data. Pin 4 (RTS) and pin 20 (DTR) are the
important signals on the printer for this method of flow control. The host must be capable
of supporting this flow control method for it to function properly.

Section 3. Interface Specifications
X-On/X-Off Flow Control
X-On/X-Off flow control must be used whenever hardware (Ready/Busy) flow control
is not available or desirable. Instead of a voltage going high/low at pin 20, control
characters representing "Printer Ready" (X-On = 11 hexadecimal) or "Printer Busy" (X-
Off = 13 hexadecimal) are transmitted by the printer on pin 2 (Transmit Data) to the
host. In order for this method of flow control to function correctly, the host must be
capable of supporting it. X-On/X-Off operates in a manner similar to the function of
pin 20 (DTR) as previously explained. When the printer is first powered on and goes
on-line, an X-On is sent out. In the Single Job Buffer mode, when the printer receives a
viable job, it transmits an X-Off and begins printing. When it is done printing, it
transmits an X-On. In the Multi Job Buffer mode, the printer sends an X-Off when the
when the "Buffer Near Full" level is reached and a X-On when the data level of the
buffer drops below the "Buffer Available" mark. When the printer is taken off-line
manually, it transmits an X-Off indicating it cannot accept data. When it is placed back
on line manually, it sends an X-On, indicating it is again available for receipt of data. If
an error occurs during printing (paper out, ribbon out), the printer sends nothing in the
Single Job Buffer mode since the last character transmitted was an X-Off. When the
error is cleared and the printer is resumes printing, no X-On is sent until the current job
is completed and the printer is once again ready to receive the next job. If it is in the
Multi-Job Buffer mode, it sends an X-Off as soon as an error condition is detected.
When the error is cleared and the printer is placed back on-line, it transmits as X-On
indicating it is again ready to accept data.
Upon power up if no error conditions are present, the printer will continually send
X-On characters at five millisecond intervals until it receives a transmission from the
host.
Data Streams
The data streams for X-On/X-Off and Ready/Busy flow control are constucted in the
same way as they are for Ready/Busy flow control.
<ESC>A .. Job#1 .. <ESC>Z<ESC>A .. Job#n .. <ESC>Z
Example: <ESC>A .. Job#1 .. <ESC>Z
NOTE: All characters are in ASCII.
3.6 Universal Serial Bus (USB) Interface
The Universal Serial Bus (USB) interface is a Plug-In Interface Module that can be
installed by the user. It requires a driver (shipped with each printer that has the interface
installed) that must be loaded on your PC and the PC must be configured to support USB
peripherals using Windows 98 or above. Details for loading the USB driver are contained
in the USB Interface Manual that is shipped with each printer with a USB Optional interface
installed. Up to 127 devices may be connected to a USB port.

NOTE: The signals on pins 1, 3, 4, 6, 9 and 10 each have an open collector output. These pins normally
measure +.07V maximum when a true condition exists. If a false condition occurs, the voltage will drop to
0V. To achieve a signal level of +5V, you must add a 330 ohm, ¼ W pull-up resistor between the open
collector output pin and Vcc (pin 13) as illustrated. This will provide a signal level of +5V for a true
condition and 0V when a false condition exists. The maximum voltage that can be applied to these pins is
+50V and the maximum current they can sink is 500 milliamps.

4.1 Overview
This chapter describes how to check CL408e/CL412e Printers voltage levels and adjust
threshold sensor voltages.
The power supply converts 125 VAC into regulated DC voltages. The printer uses: +5V
and +24V. These DC voltages are not adjustable, however you can measure these DC
voltages at test points located on the PCB. Section 4.2 contains procedures for measuring
DC voltage levels.
You can adjust threshold voltage levels for label sensors. These adjustments are made to
allow for variations in the characteristics of the labels used with the printer. If you cannot
calibrate the label sensor voltage level within the specified voltage range, you should
reposition the label sensor by following the adjustment procedures included in this
section. After completing the label sensor adjustment procedures, perform the label
sensor voltage level adjustment procedure.
You can check or adjust:
• Power Supply
• Label Sensors
• Ribbon Sensor
• Pitch Offset
• Label Positions
Checks and adjustments in this section require standard metric tools.
Also required:
Digital Multimeter required for use with SA TO TP Test Module (V oltage
Checker) Part # RH1773100 and is required for most electrical
adjustments.

4.9b Ribbon Sensor Voltage Checking
There is no adjustment POT for the ribbon sensor on the CL408e/412e. The CE POT on
the main logic board has no effect on the voltage values. The voltage values only can be
taken off the connector SEN4 on the display.
Refer to illustrations below.
PIN 1 = Brown
PIN 2 = Red
PIN 3 = Orange
PIN 4 = Yellow
PIN 3 (Signal) and PIN 4 (Ground) are the test pins. Low value when the carbon assembly
is rotated is around 0.16V. High value is around 4.8V.
If the voltages you monitor are at or close to these voltages, the ribbon out problem is
being caused by improper ribbon tension adjustment.
If the voltages are not at or close to these values, it indicates a component problem. The
order suggested for component replacement trouble shooting is ribbon sensor first, display
panel next, and finally the main logic board.
