1.3.2 EEE1284.4 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 command with another device at the same time across a single point-to-point link. The protocol is not, however. a device control language. It dose 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 IEEE1284.4. Three function modes of IEEE1284.4 protocol, "On", "Off" and "Auto" are available , and the setting is defined based on the data stored in the value in EEPROM address 25.
o On
Communication in IEEE1284.4 packet mode is started by receiving a magic string (1284.4 synchronous commands). Until a magic string is received, other commands are discarded.
o Off
Communication is carried out in the conventional mode. A magnetic string (1284.4 synchronous commands) is discarded.
o Auto
Communication is carried out in the conventional mode until a magic string (1284.4 synchronous commands) is received. By receiving a magic string, communication in IEEE1284.4 packet mode is started. The factory setting for IEEE1284.4 mode is "ON". But, after complete the initial ink charge operation, the setting of the EEPROM is set to "AUTO". The change in this setting will be effective when the power is back on after the initial ink charge operation.

2.1 Overview
This section describes the operating principles of the printer mechanism and electrical circuit boards. The Stylus COLOR 580 has only the following two circuit boards and dose not have control panel:
Paper Eject Roller PF Roller
Star Wheel Roller CR Timing belt
o Main board:C379MAIN-C (or C379MAIN-B) *1 o Power supply board:C367 PSB/PSE
NOTE: *1): C379MAIN-B board is used for the product in the first mass production and it will be changed to C379MAIN-C board at an early date. The major difference is that C379MAIN-C has one chip CPU which include the ASCI function. This section describes the operation principle of C379MAIN-C.
CR unit HP/PE/IC Sensor LD Roller
2.1.1 Printer Mechanism
The printer mechanism for Stylus COLOR 580 is designed newly. But, the basic component of the printer mechanism is same as previous product. This printer consists of Print Head, Carriage Mechanism, Paper Feeding Mechanism, Paper Loading Mechanism, Ink System (Pump Mechanism, Cap Mechanism, and Carriage Lock Mechanism). Like other EPSON ink jet printers, the Stylus COLOR 580 is equipped with two stepping motors; one for ASF, Paper feeding/ Pump mechanism, and one for CR mechanism. ASF unit uses rear entry front eject system. This ASF unit is also designed newly and single LD roller loads the paper to the printer mechanism. For cap assembly, Stylus COLOR 580 uses valveless mechanism; new design for this model.

2.1.2 Printhead
The print head uses a new developed U-CHIPS head and Stylus COLOR 580 can perform multiple shot printing and variable printing. Printheads nozzle configuration is as follows.
Head Driver Board
n 48 nozzles x 1 row: Black (nozzle pitch of the row: 1/120 inch) n 45 nozzles x 1 row: Color (nozzle pitch of the row: 1/120 inch)
In the one row for the color, 15 nozzles are assigned for each yellow, magenta, cyan color) The basic operating principles of the printhead, which plays a major role in printing, are the same as previous models; on-demand method which uses PZT (Piezo Electric Element). In order to uniform the amount of ejecting ink, the printhead has its own head ID (6 digits for this printhead) which adjust PZT voltage drive features. The printhead stores the head ID to EEPROM and generates appropriate PZT drive voltage to prevent amount of ink from varying by printheads. Following explains printhead basic components.
Nozzle Plate PZT
Ink Cartridge Needle
Filter
Cavity
o PZT
PZT is an abbreviation of Piezo Electric Element. Certain amount of voltage expands and contracts PTZ. The drive wave generated on MAIN board drives PZT and PZT pushes the top cavity which has ink stored to discharge the ink from each nozzle on the nozzle plate.
Figure 2-2. Printhead Sectional Drawing
2.1.2.1 Printing Process
This section explains the process in which the printheads of On-Demand inkjet printers eject ink from each nozzle. 1. Normal State: When no printing signal is sent from PC, or no PZT drive voltage is applied, PZT does not change shape, therefore PZT does not squeeze the cavity. Ink pressure inside the cavity is kept normal. (Refer to Figure 2-3.)
o Ink Cavity
The ink absorbed from the ink cartridge goes through the filter and then is stored temporarily in this tank called "cavity" until PZT is driven.
o Nozzle Plate
The board with nozzle holes on the printhead surface is called Nozzle Plate.
o Filter
When the ink cartridge is installed, if any dirt or dust around the cartridge needle is absorbed into the head, there is a great possibility of causing nozzle clog and disturbance of ink flow, and finally causing alignment failure and dot missing. To prevent this problem, a filter is set below the cartridge needle, where ink is filtered.
2) Ejecting State: When the print signal is output from the C379MAIN-C board, IC (Nozzle Selector) located on the printheads unit latches data once by 1-byte unit. An

appropriate PZT latched by the nozzle selector is pushed into the cavity by the common voltage applied from the main board. By this operation, ink stored in the cavity spurts out from nozzles.(Refer to Figure 2.1.2.2.) Ink Path PZT Ink Cavity
Revision A o Multiple shot printing
This printing mode is developed to improve the print quality on plain paper or transparencies in low resolution. The multiple shot printing mode uses normal dot and the number of dot shots varies from 1 shot to maximum 4 shots depending on the print data to enable sharp image output even in a low resolution.
o Variable dot printing
This printing mode is developed to improve the print quality on exclusive paper. This mode is basically the same as variable dot printing mode used on other products /; micro dot, middle dot, and large dot compose this mode. Print dot size varies according to print data and this mode enables even sharper image output on exclusive paper. Nozzle Nozzle plate PZT drive voltage
Figure 2-3. Printhead printing process
2.1.2.2 Printing Method
For print dot system, Stylus COLOR 580 has the following two kinds of printing modes.
n Multiple shot printing n Variable dot printing
The above two printing modes are automatically selected depending on the media and the resolution setting of the printer driver. The following explains each printing mode.

2.1.5 Paper Loading Mechanism (ASF Unit)
The Paper loading mechanism is positioned at the printer rear. The Paper loading mechanism loads paper at the ASF unit and feeds paper to the PF roller. This ASF unit was designed newly for this product and consists of LD roller, Pad holder (Paper return plate), ASF Frame, Hopper, and so on. For the major feature of this ASF unit, ASF HP sensor is not used and the single LD roller is built in the ASF unit. Drive sent from the PF motor is always transmitted to the ASF unit side. But, the Change lever and the Clutch mechanism switch ON/OFF the PF motor drive to the LD roller with the motor rotational direction. Drive from the PF motor is transmitted to the ASF unit as described below:

The Clutch mechanism transmits the PF motor drive to the LD roller shaft only when the Clutch gear rotates CW direction after the Change lever releases the Clutch lever. If the Clutch gear rotates CCW direction, the PF motor drive is not transmitted to the LD roller. This is due to the combination of the shape of the Clutch gear and the Clutch lock tooth such as described on the figure. 1. When the paper is advanced with the PF roller, the Change lever is set on the Clutch lever and the Clutch is pushed down as above Step1's figure. As the result, the Clutch gear (*1) is released from the Cluck lock tooth and the drive from the PF motor is not transmitted to the LD roller shaft. When the PF pinion gear rotates CCW direction in the above Step2's figure, the Change lever moves to the left direction with the CCW rotation of Combination gear 11.2, 32.4. The Clutch turns back to the engagement position by the tension force of the Tension spring 0.143 and the Clutch gear is engaged with the Clutch lock tooth as above Step2's center figure. When the PF pinion gear rotates CW direction in the above Step3's figure, the Change lever moves to the right direction with the CW rotation of the Combination gear 11.2, 32.4. And the drive from the PF motor is transmitted to the LD roller shaft via Clutch gear and Clutch lock tooth.

2.1.6.2 Capping Mechanism
The capping mechanism covers the printheads with the cap holder to prevent the nozzle from increasing viscosity when the printer is in stand-by mode or when the printer is off. This product has valveless cap system. Air valve function used for the previous models pumps and ejects ink only inside the cap by absorbing ink with the valve open. By opening the Air valve, the negative pressure is decreased and only the ink inside the cap is ejected. (the ink is not absorbed from Ink cartridge or head cavity.) But, valveless cap system, this operation is done out side of the capping area. The CR moves to left side of the Cap assembly and the pump absorbs the ink inside the cap.
2.1.7 Ink Sequence
o Initial ink charge
After the product is purchased and the printer is turned on for the first time, the printer must be performed the initial ink charge and charges ink inside the head cavity. When the initial ink charge is completed properly, the printer releases the flag inside the EEPROM and no initial ink charge will be performed next time the power is turned on. Stylus COLOR 580 takes 110 seconds to complete the initial ink charge sequence and consume about half of the brand-new black ink cartridge.
o Manual Cleaning
Unlike the previous models, the manual CL is available only though the utility included in the printer driver because this printer dose not have control panel. Stylus COLOR 580 provides three types of manual cleaning to clean air bubbled or clogged ink with viscosity or foreign substances. The following manual CL sequences can be executed by the utility included in the printer driver.

Like the previous products, CL1 is selected automatically and performed in case any print check is not executed between each manual CL. Additionally, if the manual CL is performed with over 5 pages printing cycle, CL1 is always selected and performed. Additionally, if either black or color I/C is ink low or end condition, any manual cleaning is prohibited and it is displayed on the STM3.
Revision A o Flashing
This printer performs the following two kinds of the Flashing for the following purpose.
n Periodical Flashing
This is due to avoid the increment of both ink's viscosity in the printhead nozzle during the continuous printing and the specific small amount of the ink is ejected in the cap based on the periodical flashing timer.
n Periodical large amount Flashing
This is due to avoid the increment of black ink's viscosity in the print head nozzle during the continuous printing and large amount of the ink is ejected in the cap based on the periodical large mount flashing timer.
o Timer Cleaning
Unlike the previous product, this printer dose not have Timer IC and Lithium battery which is used for the backup power source for Timer IC. So, this printer manages the printer off period or cleaning cycle by using the following method. The printer driver sends the time command to the printer every D4 command transportation. The time command is generated based on the PC's timer and it consists of year and month, date, hour, minutes, second. As soon as the printer receives the time command from the printer driver, it is compared with the latest cleaning time which is stored in the 6A, 6B address of the EEPROM. And if the timer cleaning period is over the specific period, the printer perform the timer cleaning automatically and store the time command in the 6A,6B address of the EEPROM. In case the timer cleaning period is not over the specific period, the time command is not stored in the EEPROM and it is abandoned. Maximum 0.48ml of the ink is consumed in the Timer cleaning. (0.24ml of each black and color ink is consumed.)

NOTE: C379MAIN-B board is used for the product in the first mass production and it will be changed to C379MAIN-C board at an early date. The major difference is that C379MAIN-C has one chip CPU which include the ASCI function. This section describes the operation principle of C379MAIN-C This section provides operating principles of C379MAIN-C Board and C367 PSB/PSE Board. Refer to Figure 2-16 for the major connection of the each boards and their roles.

This printer dose not have the Power SW. So, the printer is turned on when the AC cable is connected to the AC inlet. If the AC cable is disconnected from the AC inlet, this power supply circuit supply 5 voltage for approximately 70us to keep the logic circuit. AC voltage input from AC inlet first goes through filter circuit that removes high frequency components and is then converted to DC voltage via the rectifier circuit and the smoothing circuit. DC voltage is then lead to the switching circuit and FET Q1 preforms the switching operation. By the switching operation of the primary circuit, +42VDC is generated and stabilized at the secondary circuit. This +42VDC generated by the secondary circuit is converted to +5VDC by the chopping regulator IC of the secondary circuit.
