1.3.5 Interface Selection
The printer has two built-in interfaces: the USB and parallel interface. These interfaces are selected automatically.
Automatic Selection In this automatic interface selection mode, the printer is initialized to the idle state while scanning which interface receives data when it is powered on. Then the interface which received data first is selected. When the host stops data transfer and the printer is in the stand-by state for seconds, the printer is returned to the idle state. As long as the host sends data or the printer interface is in the busy state, the selected interface is let as it is. Interface State and Interface Selection When the parallel interface is not selected, the interface gets into the busy state. When the printer is initialized or returned to the idle state, the parallel interface gets into the ready state. Note that the interrupt signal such as the -INIT signal on the parallel interface is not effective while that interface is not selected.
1.3.6 IEEE1284.4 Protocol
The packet protocol described by IEEE1284.4 standard allows a device to carry on multiple exchanges or conversations which contain data and/or control information with another device at the same time across a single point-to-point link. The protocol is not, however, a device control language. It does provide basic transport-level flow control and multiplexing services. The multiplexed logical channels are independent of each other and blocking of one has no effect on the others. The protocol operates over IEEE1284.
Automatic Selection An initial state is compatible interface and starts IEEE1284.4 communication when magic strings (1284.4 synchronous commands) are received.
Generally, hosts abandon data transfer to peripherals when the peripheral is in the busy state for dozens of seconds continuously. To prevent this kind of time-out, the printer receives data very slowly, several bytes per minute, even if the printer is in the busy state. The slowdown starts when the remaining input buffer becomes several hundreds of bytes, and the printer finally gets into the busy state continuously when the input buffer is full. USB and IEEE1284.4 on the parallel interface do not require such function.

Step 2

Change lever

Clutch gear

Printer front side
When the paper is loaded (pick up) from the ASF unit, the Change lever moves to the printer front side with the CCW rotation of the PF motor pinion gear and releases the Clutch lever. As the result, the Clutch turns back to the engagement position by the tension force of the Tension spring 0.143. And the Clutch lock tooth is engaged with the Clutch gear as right figure.
Clutch lever Clutch PF motor pinion gear CW rotation The PF motor pinion gear rotates CW direction and the drive from the PF motor is transmitted to the ASF LD roller shaft through the Clutch lock tooth and the Clutch gear. The ASF hopper release lever rotates with the ASF LD roller and release the ASF Hopper. The ASF hopper is pushed with the Compression spring 4.80 and the paper is picked up with the ASF LD roller.

The package contents may vary in certain locations.
The ink cartridges packaged with your printer are for initial setup. In order to maintain high quality printouts, your printer will use large quantities of ink during the setup process. As a result, the ink cartridges used for setup will empty faster than normal.

Unpacking the printer

Remove all tape and protective materials from the printer and lift the top corners of the output tray off of the knobs on the top of the printer to lower it. If the output tray is curled, bend both sides of the tray upwards at the seams.
Insert the paper support into the slots at the rear of the printer and place the printer on a flat, stable surface.
Plugging In and Connecting the Printer
Your printer connects to your computer via the parallel or USB interface. Macintosh computers can only be connected via the USB interface. Depending upon your geographic location, you may need to obtain the appropriate cable. See Options and Consumable Products in the Daily Use guide for details. Note: In order to connect your PC via the USB interface, your computer must be a Windows 98 or Windows 2000 pre-installed model that is equipped with a USB port. If you use a USB hub, we recommend that you connect the printer to the first tier of the hub, or connect the printer directly to the computers USB port.

This printer uses ink cartridges equipped with IC chips. The IC chip accurately monitors the amount of ink used by each cartridge, so even if a cartridge is removed and inserted again, all of its ink can be used. However, some ink from both color and black ink cartridges is consumed each time a cartridge is inserted because the printer automatically checks reliability. Be sure to use the ink cartridges packed with your printer the first time that you install ink cartridges. Refer to the appropriate section below.
Using the Setup utility for Windows 98, 95, 2000, and NT 4.0 users
The Setup utility should open automatically when your printer software installation is complete. Follow the on-screen instructions. If you cannot access the Setup utility, refer to the next section.

If you are a Macintosh or Windows 3.1 user, or cannot access the Setup utility, use the printers control panel to install the ink cartridges. Before installing the ink cartridges, note the following.
Warning: The ink cartridges are self-contained units. Under ordinary use, ink will not leak from a cartridge. If ink does get on your hands, wash them thoroughly with soap and water. If ink gets into your eyes, flush them immediately with water.
Note: Do not open the ink cartridge packages until just before you install them; otherwise, the ink may dry up. Follow the steps below to install the ink cartridges. 1. Lower the output tray, then open the printer cover.
Turn on the printer by pressing the 2 power button. The print head moves to the center, which is the ink cartridge installation position. The 2 power light flashes and the error light comes on.
Caution: Do not move the print head by hand. Doing so may damage the printer.
Push back the release tabs and lift up the ink cartridge clamps.
Open the ink cartridge packages. Next, remove only the yellow tape seals from each cartridge. Caution: You must remove the yellow tape seals from the cartridges before installing them; otherwise, the cartridges will become unusable and you will be unable to print. If you have installed an ink cartridge without removing the yellow tape seal, you must remove the cartridge and install a new one. Prepare the new cartridge by removing the yellow tape seal, then install it in the printer. Do not remove the blue portion of the tape seal from the cartridges; otherwise, the cartridges may become unusable. Do not remove the tape seals from the bottom of the cartridges; otherwise, ink will leak. Do not touch the green IC chip on the side of the cartridge. Doing so may prevent normal operation and printing. Do not remove the green IC chip from the side of the cartridge. If you install an ink cartridge without a chip, the printer may be Do not touch this part. damaged.

Align the tabs on each ink cartridge so that they are resting on the tabs protruding from the base of the opened ink cartridge clamps. Do not apply excessive force to the cartridges.
Caution: Make sure that the ink cartridge tabs are not under the tabs protruding from the base of the opened ink cartridge clamps, as this can damage the clamps.
Note: Install both ink cartridges. If either of the cartridges is not installed, the printer will not work. Lower the ink cartridge clamps until they lock into place. Press the A ink cartridge replacement button. The printer moves the print head and begins charging the ink delivery system. This process takes about two and a half minutes.
