(Note) Direction of printing during face-to-face shooting

When printing from DSC-F1, data on angle of rotation of the image will not be transferred. Consequently, images shot by

face-to-face shooting (shooting with the camera rotated) will be opposite the printing direction.

(See Fig. 3)
Even if the images are rotated in DSC-F1, the printing direction will not change.
In this case, change the direction of inserting the print paper into DPP-M55, or input the images to the PC, rotate the

images, and then print.

DPP-M55 is always in the data reception mode while the data transmission indicator is lit.

DPP-M55 has the following three input terminals.
W IrDA terminal

W DOS/V PC cable terminal

W Macintosh cable terminal

When a signal input is detected, the input destination is switched automatically. While the signal from one input terminal

is being read, the other pin inputs will be ignored.

Consequently, the DOS/V and MAC cable terminals can be used at a time without any problems.

When the IrDA signal from DSC-F1 is received, a short beep is sounded once, and reading of the image data starts.
W If the signal from DSC-F1 cannot be received by DPP-M55, “Print Error” is displayed on the DSC-F1 LCD

about 50 seconds after data transmission starts.

One image takes about 85 seconds to transfer.
When one image data is read on DPP-M55, a long beep is sounded once, and printing starts.
W If an error generates during the transfer of image data, that data is re-transferred from DSC-F1. Consequently, if

no long beep is sounded about 85 seconds later, it means that an error occurred during data transfer, and the data
transfer state must be corrected.

(Important) Data transmission to the DSC-F1

Image data can be transmitted from DSC-F1 to PC via DPP-M55. However, Image data can not be transmitted from PC

to DSC-F1 via the DPP-M55.

To transmit image data from PC to the DSC-F1, connect PC to DSC-F1 directly.

•

Detection of print paper
When data transfer completes, detection of print paper is performed. The detection of the insertion of print paper is

detected by the paper edge sensor (PH901) near the slit.

W If no print paper is inserted, the print paper indicator blinks. If paper has been inserted, printing will begin.

W If several sheets of images are being printed from DSC-F1, if print paper is not inserted within 1 minute after

data transfer completes, DSC-F1 displays a print error on the LCD and stop the continuous printing.

•

Descent of head
When the insertion of print paper is detected, the head UP/DOWN motor (M902) rotates, the head descends, and the

“paper suck in” mode is set.

DPP-M55 winds the print cartridge to the print start position.
W The long black line at the borderline between C (cyan) and Y (yellow) of the print cartridge is detected by the

sensor, to detect the initial position. This long black line cannot be seen if the print cartridge is not wound.

W If the print cartridge is tangled or if the sensor is faulty, the print cartridge may be advanced.

•

Pulling in of print paper
When the paper pull in mode is set, the PLATEN motor (M904) is rotated, and the print paper is pulled into the unit

completely.

At this time, the paper edge sensor (PH901) and the jamming detection sensor (PH950) further inside measure the

length of the print paper.

The type of print paper (normal size/postcard size) is detected from the length.
W If the print paper and print cartridge do not correspond, the print paper indicator and ribbon error indicator blink.

Replace either so that they match.

•

Winding of print cartridge
When the print paper is pulled inside the unit, the ribbon motor (M903) is rotated, and the print cartridge is wound

to the printing start position.

The printing start position is detected and set by detecting the long black line between cyan and yellow using the

ribbon mark sensor (PH903).

W If the print cartridge has been used up, it will not rotate. If the printing start position is not detected within a

certain time, it is determined as error, and the ink ribbon indicator will blink. At this time, the print paper pulled
in will be ejected to the front. (This print paper can be used again.)

W When the print cartridge is replaced, it will be wound up automatically, and printing will start from the last image

data read.

W If the cartridge is not replaced within 1 minute, DSC-F1 stops continuous image data transfer. The LCD of DSC-

F1 then displays a print error.

W If the print cartridge is not wound completely, due to malfunction of the ribbon motor, the same symptoms as

when the ink ribbon has been used up will occur.

•

Checking of head temperature
When the print cartridge is wound, the temperature of the thermal head is checked. The head temperature is checked

by the temperature sensor located near the head. When the head temperature rises, the voltage of the head temperature
detection terminal (Pin (º of IC503) also rises.

DPP-M55 does not start printing until the head temperature becomes the appropriate level. When continuos printing

is performed, and the temperature sensor is above 40°C, the FAN motor (M901) is rotated, the air outside the unit is
sucked into the upper panel to lower the head temperature.

After printing, the FAN motor may continue rotating, but this is not a fault.
W Be careful not to attach the FAN motor reversed.

Printing
When the head temperature is appropriate, the head UP/DOWN motor (M902) rotates, the head further descends,

touches the ink ribbon, and the “Print” mode is set.

The three colors are printed in order from the yellow ink ribbon, magenta ribbon, and then the cyan ribbon.
When printing of one color ends, the “paper pull in” mode is set to raise the head slightly, the print paper is pulled

back, and the printing of the next color starts.

The switching of the ink ribbon color is performed by rotating the ribbon motor (M903) and detecting the short black

line between the colors using the ribbon mark sensor 0.

W When paper jams during printing, and the paper can be seen from the front and back of the unit, pull out the

paper.

W If paper is jammed at the position detected by the jamming detection sensor (PH950), all indicators will start

blinking.

W If paper has jammed at a position which cannot be detected by the jamming detection sensor, the indicators will

not light up to alert.

(Reference Information) Causes of paper jamming

When the auto feeder is used, two sheets of print paper may be pulled in by static electricity. In this case, remove the

print paper from the auto feeder, and turn each paper to remove the static electricity between the paper.

When the print paper is inserted by hand, inserting the paper crookedly or inserting curved paper will cause paper

jamming.

Paper jamming will also occur if the mechanism such as the cassette guide T is not assembled properly.

•

End of printing
When printing ends, a long beep is sounded once, and the print paper is ejected. If continuous printing has been

executed from DSC-F1, the transfer of the next image data starts about 10 seconds later.

W The next print paper is not pulled in until the printed print paper has been removed in manual supply mode.

(Reference Information) Dirty print cartridge

Dirt and finger prints on the print cartridge may cause color change during printing. If printing is abnormal, rewind the

print cartridge, and check if the part causing color change is dirty, etc.

Circuit operations are performed with the following voltages.

• +22V

Voltage for the thermal head, PLATEN motor (M904), and motor driver (IC900).
The head voltage is adjusted by VR201 when the thermal head has been replaced. When the head voltage changes, the

color darkness also changes.

• +7V

Voltage for the motor driver (IC900) and auto feeder motor.
Voltage output is controlled by the switching output of Pin !¡ according to the voltage input to Pin 1 of IC203 as the

switching regulator controller of the board (J/US:SR784, AEP:SR786).

• D+5V

Voltage for the digital circuit regulated from +7V by IC110 of the DK-31 board. Voltage for most of the digital signal

processing operations of the system controller, mechanism controller, DRAM, etc.

• +5V

Voltage for the FAN motor regulated by IC202 of the board (J/US:SR784, AEP:SR786).

(Repair Tips) Checking of power supply board

Each voltage (+22V, +7V, D+5V, +5V) can be output by removing only the power supply board.

The RXD signal input from the IrDA terminal (IC650) is decoded by the IrDA interface (IC507) and recorded in the 4

Mbit DRAM (IC506) by the address bus (A0 to A3) and data bus (D0 to D7) via the microprocessor (IC503).

The IrDA communication clock is output by X500 (48 MHz) and IC500.

The image data signal from jack 1 is latched by the flip-flop (IC118) and recorded in the 4 Mbit DRAM (IC506) via the

microprocessor (IC503).

The other control signals are waveform-shaped by the buffer (IC123), NOR gate (IC101), and gate (IC102), and input/

output together with the system controller, etc.

The ±5Vp-p input data and clock are voltage level shifted by IC103 and input to the system controller (IC503).

The image data input by each route is decoded by the system controller (IC503), and recorded in the 4 Mbit DRAM

(IC506) by the address bus and data bus.

The data recorded in the 4 Mbit DRAM is read to the mechanism controller (IC505) and output to the thermal head from

PDT0 (Pin @£) and PDT1 (Pin @™).

The image data is output in order from yellow, magenta, and cyan.

W If printing cannot be carried out, check if the flexible board is connected properly.
