4-8 Exclusive Processes
4-8-1 Exclusive processes in Memory Card Direct Printing and Digital Camera Direct Printing
As it is impossible to simultaneously process Memory Card Direct Printing and Digital Camera Direct Printing, the following actions are taken:
When the digital camera is connected via the digital camera connection cable:
Memory Card Direct Printing settings and operation are not possible.
Setting items are not displayed in the operation panel, and the print start button is invalid.
"Digital camera connected." is displayed on the LCD viewer.
When direct printing from the memory card:
Digital Camera Direct Printing is impossible. (Settings in the digital camera are possible.)
If Digital Camera Direct Printing print operations are attempted, an error is displayed in the digital camera.
4-8-2 Exclusive process control between direct printing and printing from the host computer
As it is impossible to simultaneously process direct printing from memory cards or digital cameras and printing from the host computer, the following actions are
taken:
When printing from the host computer:
Memory Card Direct Printing and Digital Camera Direct Printing are impossible.
When printing via Memory Card Direct Printing and Digital Camera Direct Printing:
Printing from the host computer is impossible.
4-8-3 Exclusive processes in host computer memory card access and Memory Card Direct Printing
Writing of data from the host computer to the memory card, while reading image data from the memory card for direct printing is conducted as follows in order to
avoid overwriting the image being printed in Memory Card Direct Printing, via the host computer.
When direct printing from the memory card:
Writing data from the host computer to the memory card is not possible. (Reading of data is possible.)
An error is displayed in the host computer at the start of data writing operations.
When writing data from the host computer to the memory card*
Direct printing from the memory card is not possible.
Even if the print start button is pressed, printing will not start.
*To write data from the host computer to the memory card, the mode needs to be changed to the Read/write mode, using the Memory Card Utility.
4-8-4 Exclusive processes between the memory card and memory card
In the card slot, there is a slot for SM, MS, and SD/MMC (used in common, however, multiple cards can not be inserted simultaneously) and a slot for a CF card.
However, even though a CF card and other card are inserted simultaneously, as one drive only is always valid, control are performed as follows:
The card inserted first has priority. Even if a card is inserted into a drive other than the current drive, this action is ignored.
When the current drive is removed, the other drive is checked. If a card is detected, the same control as when the former card is removed and a new card is inserted,
is performed.
When multiple cards are inserted when the printer is powered on, the drive is checked in the order of CF, SM, MS, and SD/MMC, and the drive in which a valid card
is detected becomes the current drive.
When the memory card is uninstalled from a computer, the power supply for the card with the current drive is halted, and the no card inserted status is valid.
However, as long as the card is not removed from the current drive, even though another card is inserted into another drive, this action is ignored.
4-9 LCD Viewer
The iP6000D LCD viewer is a 2.5 inch (176 x 128 pixel, 65,000 colors) color LCD, and realizes two functions: image display and operation display with the
operation panel. Operations are carried out by the user selecting the desired menu item from within a nested menu displayed on the LCD viewer, and by pressing the
OK button, proceeding with the next step. During the process, if an image needs to be selected, it can be displayed on the LCD viewer, and the selected image can be
changed by using the left and right cursor buttons.
To protect the LCD viewer and preserve the backlight life, when no button operation has occurred for five minutes, the LCD viewer is powered off. When any key
other than the Power and Resume buttons and Paper Feed switch is pressed with the LCD backlight off, the LCD viewer turns on, however the original function of
the key is invalid.
The content displayed on the LCD viewer changes depending on the user's operation.
Eg. When printing is being performed from the PC, the LCD viewer displays "Printing from the computer", when a digital camera is connected, the LCD shows the
printer status by displaying "Digital camera connected", and when an error occurs during printing, such as the paper out error, the LCD shows the error by displaying
"No paper. Load paper and press Resume".
When Card Direct Printing is performed, the LCD viewer becomes the operation display of the operation panel.
