CAUTION

When returning the repaired printer to the customer, make sure

 

the Printhead is covered with the cap and the ink cartridge is

 

installed.

If the Printhead is not covered with the cap when the printer is off, turn on the printer with the ink cartridge installed, make sure the Printhead is covered with the cap, and then turn the printer off.

1.5 Interface

The printer has USB interfaces and memory card slots of the following specifications.

1.5.1 USB Interfaces

The printer has two USB ports; USB Device port for connecting with a host device such as a computer, and USB Host port for connecting with an external device such as DSC (Digital Still Camera).

Note: • Memory Stick/PRO, SD/MMC and xD-Picture Card shares the same slot.

When cards are inserted in the two slots at once, the slot which will be accessed first is determined according to the priority shown in the table.

To select a card that has been inserted in a non-active slot, first remove the card in the active slot.

In memory card direct printing mode, the image files in the active slot are valid and have assigned frame numbers. The number of images will not change if a card is inserted in another nonselected slot.

When the card inserted in the slot is accessed from the PC, only one drive is displayed at a time as a removable disk* and only the card that is in the active slot can be accessed via the removable disk. A card that has been inserted into a non-selected slot cannot be accessed.

(This is for Windows. For Macintosh, the card in the active slot will be mounted on the desktop.)

Does not support 5V type of memory cards.

When a memory card is being accessed, do not touch the memory card.

For detailed information on the supported file system and formatting the memory card, refer to “1.7.2 Memory Card Direct Print Function (p.21)”.

1.7 Specifications of Each Function

1.7.1 Stand-alone Copy Function

With the press of the Copy button, the printer goes into the Copy mode and displays a menu for copying. The menu allows the user to specify the number of copies up to 99, select a copy layout from the preset options shown in Table 1-15, and specify the desired scaling. Duplex copying is available with the optional duplex unit (standard equipment for EAI models). When the duplex unit is installed, menu options for duplex copying are enabled which includes “Dry Time”. The “Dry Time” allows the user to select a time period for drying paper printed on its front surface (refer to Table 1-16).

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*1,2

DVD-R: 4.7GB*2

USB flash memory*3

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.

 

 

 

CHECK

 

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

POINT

 

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

CHECK

The maximum number of writing times

POINT

• 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.

Runs an ink cartridge replacement sequence. The sequence also can

Change Ink Cartridge

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

Figure 2-5. Nozzle layout

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.

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).
