1.FEATURESThis printer is a type of thermal transfer printer, and it prints
by subliminating ink through the print head heating an ink
ribbon to which solid ink has been applied and having it
adhere to special paper coated with a polyester resin.
Fine changes can be made in the printing density by control-
ling the heat applied, and it is possible to present continuous
tones like those in photographs.
In addition, since a system of attachment to a platen roller
and rotation is used instead of a system of moving the paper
back and forth, there is no time lost in reversal of the paper
feed, and complete printing to the edges is possible because
of the attachment of the paper to the platen roller.
Furthermore, PictBridge is used, so simple operations can be
implemented without a PC.
2.OUTLINE OF CIRCUIT DESCRIPTION2-1.Power supply sectionA mechanical switch is used for the power switch, and the con-
figuration is such that it a reset is carried out when the power is
turned ON/OFF.
The necessary voltages are created by a DC-DC converter from
the 24 V DC supplied by the AC adapter.
The 24 V for the print head is only supplied to the head during
printing with the turning ON of a FET by the head-on signal. In
addition, since the print head voltage affects the density of print-
ing, the voltage changes are controlled within 3%.
The D-D converter IC supplies 12 V to the motor system and 5
V to the head driver and USB systems.
From the 5 V created by the D-D converter IC, 3.3 V is created
by a series regulator, and 1.9 V is created from that 3.3 V by a
series regulator.
2-2.Motor driver sectionIC 951 is a driver for the stepping motor that drives the platen
roller.
If there is an abnormality in the rotation of the stepping motor,
printing irregularities will occur.
The stepping motor has 24 V drive.
IC 952 is the ink ribbon driver, and that drives the ink rev and in
the ink cassette.
They ink ribbon motor has 12 V drive.
IC 953 is the head position motor driver, and rotates to put the
cam into various positions for standby, paper ejection, paper
and ribbon feed, paper supply, and printing.
The head position motor has 12 V drive.
12 V is applied without alteration to the fan drive, and it is turned
ON and OFF by a FET.
2-3.Main circuitIC 101 is the CPU, and IC 102 is ASIC.
The CPU clock of 16.67 MHz is created by X11101, and it is
increased to 133.67 MHz within the CPU for operation.
The BUS clock is 66 MHz, and the ASIC operates on that 66
MHz.
For CPU resetting, IC 106 has a threshold of 2.7 V, and when it
falls below 2.7 V, a reset is performed.
Flash memory IC 121 uses 1 MB, and programs and supple-
mentary data are stored in it.
Image data broken down into the cyan, magenta and yellow
components for printing is stored in SDRAM IC 103 and IC
104.
It is set up to be able to handle data for up to 12,000,000 pixels.
The ASIC is composed of a card interface section, print engine
section and JPEG expansion section.
IC 151 is the USB host, and internally it multiplies 12 MHz to 48
MHz for operation.
IC 153 is for current limiting of the USB terminal power supply.

2-4.Thermal print headThe print head has 1280 dots, and is driven by 10 drivers.
2-5.Sensor sectionPins 1-5 of CN161 are used for the head position sensor.
Chattering is prevented by the Schmidt buffer from CN161.
The sensors are the transmission type, and the cutouts in the
detection part of the head position cam are detected.
When the power supply is turned on, initial operations are car-
ried out.
In the initial operations, the cam is moved 40 degrees (to a
point between paper/ribbon feed and paper supply), paper jams,
etc., detected; if normal, it returns to standby, and if paper is
jammed, it ejects it.
Table 1 shows the relationship between mode and sensor out-
put.
When printing ends normally in the normal manner for comple-
tion, it returns to the standby position.
CN162 is the ribbon encoding sensor.
It is a transmission sensor, and it detects the ribbon feed; wave-
form shaping is carried out in IC 163.
CN163 is the ribbon top sensor.
It is a reflection sensor, and the start of a color is detected by a
certain black marker on the ribbon. The light generated by the
ribbon sensor is reflected by the light reflecting part of the rib-
bon cassette, and the photo transistor is turned ON, but when
the marker passes by, it absorbs the light, so even if there is
light, it is not reflected and the photo transistor turns OFF, send-
ing out signal H. The markers are placed at the beginning of
each print color, but the manner in which the marker is set is
different for yellow and the other parts (magenta, cyan, OP).
Since this printer prints in the order of yellow, magenta, cyan
and OP, yellow is detected for the starting of printing.
Therefore, the markers and the sensors are positioned so that
yellow is detected by sensor 2, and the others are detected by
sensor 1.
Since the detected signal is detected by the reflection sensor
from the ink ribbon, the waveform is indeterminate, and there
may be erroneous operations if it remains as is, so waveform
shaping is performed by a comparator (IC 161).
The arrows displayed on the ink ribbon are for taking up the
slack in the ribbon, and the direction of ribbon winding is in the
order yellow, magenta, cyan and OP in the opposite direction
of the arrows.
CN164 is the paper top sensor.
It is a reflection sensor, and it carries out paper top detection
and detection of the absence or presence of paper.
Along with detecting the top of the paper, it forms the basis for
determining how many pulses after thaSince the top of the pa-
per cannot be detected when there is no paper, this also in-
cludes detection of the absence or presence of paper.
CN165 is the paper eject sensor.
Detection is carried out with the turning ON/OFF of the switch.

4. ELECTRICAL ADJUSTMENT4-1. Adjustment of Thermal Printer Head Resistance
Value1.Install the ribbon cassette and paper tray, and turn the power
on without inserting a media card.
2.While pressing the LCD operation "+" button and "-" button
(to the right of the MENU button below the LCD) simulta-
neously for two seconds or more, press the Print button to
switch to the adjustment menu mode.
The LCD panel displays "set-test."
3.Press the LCD operation "+" button six times, and select the
resistance value settings menu.
The LCD panel displays "set-res."
4.Press the MENU button, and to switch to resistance value
setting mode.
The LCD panel displays the resistance value (eg.: set-6210).
5.Set the resistance value on the LCD panel to the resistance
value displayed on the thermal head using the LCD opera-
tion "+" button and "-" button and the COPIES "+" button and
"-" button.
The first digit is set using the COPIES "+" button, the second
digit using the COPIES "-" button, the third digit using the
LCD operation "+" button, and the fourth digit using the LCD
operation "-" button.
The number displayed changes by 1 each time one of the
buttons is pressed, and after 9 comes 0.
6.End setting the resistance value by pressing the MENU but-
ton.
The LCD panel displays "set-end."
7.Turn the power off.
4-2. Firmware Updating and Correction Data Updat-
ingNOTE: Firmware updating and correction data updating can-
not be done at the same time. Furthermore, if data is
stored on both sides of a firmware update media card,
updating cannot be performed.
1.Install the ribbon cassette and paper tray, and turn the power
on with the media card containing the firmware inserted.
2.Set to index mode using the MENU button, and while press-
ing the LCD operation "+" button and "-" button (to the right
of the MENU button below the LCD) simultaneously for two
seconds or more, press the Print button to switch to the ad-
justment menu mode.
The LCD panel displays "set-test."
3.Press the LCD operation "+" button one time to switch to the
firmware update menu.
The LCD panel displays "set-up."
4.Press the MENU button to start the firmware update.
The LCD panel displays "f-up" or "h-up."
While the firmware is updating, the ink LED lights.
Do not remove the card while the firmware is updating.
The LED will go off when the firmware update is complete,
and the unit will return to index mode.
5.Check to be sure that the ink LED has gone off and that the
unit has returned to index mode. Then remove the media
card and restart.
4-3. Checking Error CodesWhen the LCD panel displays Err, press the LCD operation
"+" button and "-" button (to the right of the MENU button be-
low the LCD) simultaneously to display the error code.
