1.7.2 Memory Card Direct Print Function

This mode allows the user to directly print images stored in a memory card or media in an external device connected using the USB Host port. When a memory card is inserted in the slot, the printer automatically searches for all images in a memory card, and shows them on the LCD. The user can select images to be printed previewing them on the LCD and print specified number of copies up to 99 per image (up to 999 in total). “Print Index Sheet” function provided in the Memory Card menu makes it easier to specify images and their print settings. “Scan to Memory” function that stores scanned data directly to a memory card is also provided. The following table shows media file formats supported by the printer.

1.7.3 Backup Function

The Backup Memory Card function provided in the Setup mode allows the user to make a backup copy of a memory card on a media in an external device. Printing the backed up images directly from the external device also can be made. Writing back data backed up on the external media to a memory card cannot be made. The available media for the backup are as follows.

 MO: 128MB/230MB/640MB/1.3GB

 CD-R: 650MB/700MB

 DVD-R: 4.7GB

 USB flash memory

Note *1: A backup on 700MB or larger size CD-R is not ensured.

*2 : The CD-R/DVD-R is burned in format described in Table 1-17.

*3 : The printer cannot recognize USB flash memory that incorporates a hub.

*1,2

 Due to the file system restriction, a backup of a memory card

that has eight or more levels deep in folder hierarchy cannot be made on an ISO 9660 Level1-formatted CD-R.

 Due to the logical format of the CD/DVD, the pathname length

is restricted as described below;

•Destination media ISO9660: up to 255byte Joliet: up to 240byte

•Source media: Memory card (FAT12/16/32): up to 260byte

The maximum number of writing times

• FAT12/16-formatted media: up to 512 times (001 to 512) If any files other than backup folders exist in the route directly, the max. number of writings becomes less than 512 due to the MS-DOS restriction. When more than 512 times of writing history of an inserted MO is detected, the printer handles it as a backup error (file name, to folder hierarchy error).

• CD-R: 640MB: up to 47 times

700MB: up to 50 times

This is because each session information must be saved.

• DVD-R: 4.7GB: up to 274 times This is because each session information must be saved.

1.7.3.1 Backup Errors

If a backup operation is cancelled voluntarily or due to an error, a “Backup canceled” message appears with a hexadecimal 8-digit error code on the LCD. The following table lists the leftmost two-digit error codes that are controlled by the printer firmware.

This function is available with EAI models only. The user can create a greeting card combining an image in a memory card and a template selected from the preset options.

This function allows the user to print an image in a memory card directly on a CD/DVD. Printing a CD jacket on A4 or letter size paper is also provided.

Allows the user to clip an image or multiple images from a moving image took by a digital still camera and stored in a memory card, and print it/them. The following two options are provided.

• Print 1 Frame: prints clipped one image on one sheet of paper.

• Print N Frames: prints 12 images that are automatically clipped from the user-specified range. The images are printed on one sheet of paper using a preset layout.

1.7.6 Setup Mode

The Setup mode provides maintenance menus and various configuration setting menus. The following explains about the menu functions.

Runs a printhead cleaning. The cleaning cannot be made when low ink level is detected. In such case, an ink low error is displayed instead of running the cleaning.

This allows the user to adjust the brightness of the LCD.

The settable range is -10 (minimum) to +10 (maximum).

An adjustment to ensure the bi-directional print quality. Follow the instructions displayed on the LCD to carry out the adjustment. The default value for each of the four modes is “5”, and can be changed within the range of 1 to 9.

Runs an ink cartridge replacement sequence. The sequence also can be run from the Ink Levels menu or by following the instructions on the LCD when an ink-related error occurs.

Setting to “On” widens the platen gap to reduce friction between the printhead and thick paper. The setting is applied until the printer power is turned off, and returns to the default (Off) at the next power-on.

• Off: normal platen gap is applied.

• On: the wider platen gap is applied.

By setting to the “Memory Card Data”, the printer automatically runs a slide show using images in a memory card as a screen saver when no control panel operation has been made for 180 seconds in standby mode. If no memory card is inserted, or when this is set to “Off”, the LCD display does not change.

following two options; “End the ink levels display” or “Change Ink Cartridge”. The ink level is indicated in increment of 1%. Lower than 1% is rounded down. When the ink level becomes lower than 10%, “!” icon appears to notify the user of the ink low status

The printing range when printing on a CD/DVD or a sticker can be adjusted.

Allows the user to make a backup copy of a memory card on media in an external device. The “Folder Select” displays a folder selection screen to select the target folder in an external media to be printed.

The “Folder Select” menu item is disabled (grayout) when any external device is connected and/or no image files is detected in the inserted memory card. See on the backup function.

The print settings to be used for the camera direct print (USB Direct Print/ PictBridge) can be specified. When print settings (paper type, paper size, layout, quality, auto correct) are specified from the DSC, the DSC settings are applied and the settings made here are ignored. For more details, see

“ 1.7.4 Camera Direct Print Function (USB Direct Print/PictBridge)

2.2.2 Carriage Mechanism

The Carriage mechanism consists of the CR motor, Timing belt, Driven pulley, CR guide shaft, Carriage unit, CR scale etc.

2.2.2.1 CR Motor

The CR motor is DC motor (with brushes) and it is controlled by positional/speed information obtained by means of the CR encoder.

Since the DC motor is used, the motor may generate a excessive heat in continuous operations. To avoid this, whether the motor is driven or not, a heating value is calculated at regular intervals to monitor the motor temperature while the power is ON. When the motor temperature exceeds a specified value, the operation is forcibly paused for a specified period of time.

2.2.3 APG Mechanism

APG mechanism is provided to change the platen gap (PG) automatically within five settings using the driving force of the ASF motor.

To drive the APG mechanism for changing the platen gap, the carriage is moved to its home position to release the change lever, and then the forced clutch is switched to the Ink system/APG drive side.

Figure 2-8. Switching of Forced Clutch (APG)

Also the APG mechanism is interlocked with CDR guide mechanism. When the platen gap is set to the CDR guide position, the driving force is transmitted to the CDR guide.

See “2.2.5.2 CDR Guide Auto Switching Operation” (p.45).
