1.5.3 Valid Image Sizes
The image sizes that are valid in this machine are in accordance with DCF Version 1.0.
Note that the image sizes that are mandatory for DCF Version 1.0 are as follows:
Horizontal: 160 <= X <= 1800 (pixel)
Vertical: 160 <= Y <= 1200 (pixel)
However, this machine handles the following size range:
Horizontal: 160 <= X <= 3200 (pixel)
Vertical: 160 <= Y <= 3200 (pixel)
1.5.4 Maximum Number of Photo Data Files
This machine can handle up to 999 photo data files. If 1000 or more photo data files are
recorded in a memory card, these files are sorted in accordance with the file sort rule of
this machine, and photo data with photo numbers 1 to 999 are used as valid data. Photo
data files that are specified for printing in the camera specification file can be specified
for printing only if their photo number exceed 999. However, the numbers of photos
that can be specified for printing are limited to 999.
1.5.5 Thumbnail Image Data
Only thumbnail image data in accordance with DCF Version 1.0 (160x120 pixels in
Exif format) can be handled. This machine uses thumbnail images in index print mode.
However, you can set not to use thumbnail images in this mode.
1.5.6 File Sort
This machine sorts all the photo data files in a memory card using the information such
as date, time, and file name attached to the photo data files to assign photo numbers.
Because the photo number is assigned in accordance with the file sort rule specific to
this machine, it may not match with the photo number displayed when the data is
viewed in a digital camera.
1.5.6.1 File Sort Rule
This machine sorts the photo data files based on the following priorities:
1. Older data first. The date and time information attached to the photo data files are
used for sorting. Up to seconds are used for the time information.
2. If files with same date exist, the full-pass of the file names are sorted in normal
ASCII order.
1.5.6.2 Date Data Capture Rule
This machine tries to capture the date and time from each photo data file based on the
following priorities:
1. Date and time information in accordance with the digital camera standard format
(Exif).
2. Data and time information of the file system supported in DOS (timestamp of the
file).
3. Fixed values (1 January 1970 00:00:00)
Note that the date and time information attached to each photo data file may not match
with the date and time at which the photo was captured. Some of the said date and time
data is updated due to a calendar setting (whether the function exist/not exist, incorrect
preset date) in a digital camera, post-processing or restoring of the photo data. If the
data has been updated, this machine captures the updated date and time information for
further processing.
1.5.6.3 Date Range
This machine can handle the following range of date. If photo data files have date and
time information outside the following range, all the file sort results are undetermined.
1 January 1970 00:00:00 - 31 December 2069 23:59:59

PRODUCT DESCRIPTION Printer Initialization 20
1.7 Printer Initialization
There are three kinds of initialization methods, and the following explains each
initialization.
1. Power-on Initialization
This is the initializing operation when the printer power is turned on.
When printer is initialized, the following actions are performed:
(a) Initializes printer mechanism.
(b) Clears input data buffer.
(c) Clears print buffer.
(d) Sets default values.
2. Operator Initialization
This printer is initialized when turning the printer power on again within 10
seconds from last power off.
When printer is initialized, the following actions are performed:
(a) Cap the printer head.
(b) Eject a paper.
(c) Clears input data buffer.
(d) Clears print buffer.
(e) Sets default values.
3. Software Initialization
The ESC@ command also initialize the printer.
When printer is initialized, the following actions are performed:
(a) Clears print buffer.
(b) Sets default values.
