during repairing.
l Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
l Be careful not to apply force on the conductor when soldering
or unsoldering.
SAFETY-RELATED COMPONENT WARNING I!

What vou can do with the Digital Color
Printe; DPP-M55
The Digital Color Printer DPP-M55 enables you to
directly print the image you recorded using the Sony
Digital Still Camera DSC-R without connecting the
printer to the camera.
By connecting the DPP-MS5 to your PC or Macintosh,
you can edit images and make prints.
Direct printing of the image
recorded by the Sony Digital Still
Camera
+page 7
You don’t have to connect the printer to the camera. The
image data is transmitted from the DSC-Fl to the DPP-
MS<via infrared data communication system.
The imaze data can then be transmitted from the DPP-
M55 to the connected PC or Macintosh computer.
Exclusive sofhware to edit images
The DPP-M55 is supplied with a CD-ROM in which you
will find the printer driver and the Printer Utility
software.
You can use the DPP-M55 to print images processed not
only cm the supplied Printer Utility but also on an image
processing software such as Adobe Photoshop.
Various printouts from the Printer
Utility
You can edit images and make printouts from the Printer
Utility.
For details, see the “User’s Guide” either for Widows 95
or for Macintosh depending on your computer.

Printing
AS you must operate the camera to print, refer to the
camera’s manual for the procedure.
When the printer receives the ffrst data from the camera,
it sounds a short&p.
When the printer receives all data successfully. it sounds
a long beep and stark printing.
Printing takes about 70 seconds per sheet.
NODI
-Do not move the printer and the camera dwf”g ptiti”g.
-You may rn.,ve the printer and the camera after you hear a
long beep, except whe” makf”g several pri”=.
* The printer will sound intermittmt beepr when it cannOt
receive data pmper,y. If thfr happeru, reposition the camera
and the printeras devribed above.
* To use other funceonr o‘ tf,e printer, opt” and read
“Readme” Rfe in the supplied CD-ROM. The file contairw

MECHANICAL ADJUSTMENTS
Replacing the Thermal Head
1) Before replacing the head, print the stair-step pattern with the old
head (faulty head).
Note 1 : Only when the head is not entirely damaged with black
or white lines.
Note 2 : To reproduce the stair-step pattern, refer to “Adjusting
Method 1” in “4. Electrical Adjustments”.
2) Remove the upper cabinet. (Refer to “2. Disassembly”).
3) Remove the flat cables 1OP and 13P from the DK-31 board.
4) Remove the two screws @(BVlT2.6~6) and remove the har-
nesses 0, @, and fan holder @).
5) Remove screw @ (PS2.6~4) and remove the ribbon guide @.
6) Remove the two screws 0 (PSw2.6~8) and remove the thermal
head @from the heat sink 0.
Note : Do not remove the screw @fixing the heat sink @and
head arm @.
7) Replace the thermal head @.
Note : Make sure that the silicon grease (white) does not stick
onto the printing screen of the thermal head. If it does, remove
with alcohol.
8) Assemble inthe reverse order of steps 2) to 6).
9) Perform “Head Voltage Adjustment” of “4. Electrical Adjustments”
(Page 12).

ELECTRICAL ADJUSTMENTS
[HEAD VOLTAGE ADJUSTMENT (POWER BLOCK)]
Before performing this adjustment, print the stair-step pattern two
times continuously with the old head (Note 1) or normal unit. The
second print will be used as a sample of the print density.
Note 1 : Only when the old head (faulty head) is not entirely dam-
aged with black or white lines.
Note 2 : To reproduce the stair-step pattern, refer to “Adjusting
Method 1”.

Specification Print density should be the same as the sample.
Adjusting method:
* VR201 is
1) With the ribbon inserted, turn ON the 1-1 button, and while
holding the ribbon, move the ribbon ejection lever upward five
times. (Print stair-step pattern.)
2) After printing, repeat 1) immediately.
3) Compare the second printed pattern density with that of the sample,
and if the density differs, perform the following adjustment.
4) Adjust VR201 according to the print density.
If darker than the sample:Decrease the head voltage.
If lighter than the sample:Increase the head voltage.
5) Print the stair-step pattern two times continuously.
6) Compare the second printed pattern density with that of the sample,
and if the density differs, repeat steps 3) to 6).
Note 2 : Only one print is required after the second time.
