1.3.4 Prevention Hosts of Data Transfer Time-out

Generally, hosts abandon data transfer to peripherals when a peripheral is in the busy state for dozens of seconds continuously. To prevent hosts of time-out, the printer receives data very slowly, several bytes per minute, even if the printer is in busy state. This slowdown is started when the remaining input buffer becomes several hundreds of bytes, and the printer is finally in the busy state continuously when the input buffer is full. USB and IEEE1284.4 on the parallel interface do not require this function.

On An initial state is IEEE1284.4 communication and data that received it by the time it is able to take sy nchroni zation by magic s tring (1284 .4 syn chronou s comman ds) is discarded.



Off An initial state is compatible interface and never starts IEEE1284.4 communication even if magic strings (1284.4 synchronous commands) are received.

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 scanning which interface receives data when it is powered on. Then the interface which receives 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 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. Caution 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 sa me time across a s ingle point-t o-point link. The prot ocol i s not, however, a device control language. It provides 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.

OPERATING PRINCIPLES

CHAPTER

EPSON Stylus C60 Revision A

2.1 Overview

This section describes the operating principles of the Printer mechanism and electrical circuit boards. Like the previous printers (Stylus COLOR 480/580), the Stylus C60 has only the following two circuit boards and does not have the control panel board.



Main board : C418 MAIN



Power supply board : C417 PSB/PSE

: Due to this, the Stylus COLOR 480/580 does no t have sw itches ( Power, Err or reset, Ink cartridge replacement) and LEDs. However, the Stylus C60 has them on C418 Main board instead of the control panel board.

2.1.1 Printer Mechanism

The Printer mechanism for the Stylus C60 is newly designed. But, the basic compo nent of the Printer mechanism is almost the same as the previous printer (Stylus COLOR 480/580). This printer consists of Printhead, Carriage mechanism, Paper loading mechanism, Paper feeding mechanism, Ink system (Pump mechanism including newly designed Carriage lock mechanism, Capping mechanism including newly designed Wiper mechanism).

Like the previous printers (Stylus COLOR 480/580), the Stylus C60 is equipped with two stepping motors; one for the Paper loading/feeding mechanism and the Pump mechanism with the CR lock mechanism, and one for the CR mechanism. The ASF unit for the Paper loading mechanism uses rear entry front eject system. And, single LD roller in Holder shaft unit loads a paper to the Printer mechanism.

The Cap unit which adopts the valveless mechanism is newly designed on this printer as follows.

2.1.2 Printhead

The Printhead uses the same U-CHIPS type as the previous printer (Stylus COLOR

680), and makes it possible to perform multiple shot printing and variable dot printing. The Printhead nozzle configuration is as follows.



Nozzle layout Black: 48 nozzles x 3 staggered (nozzle pitch of row: 1/360 inch) Color: 48 nozzles x 1 row/col.

The nozzle layout when viewed from the back surface of the Printhead is shown below.

(nozzle pitch of row: 1/120 inch)

0.0706(1/360inch)

0.2117(3/360inch)

PZT PZT is an abbreviation of Piezo Electric Element. Based on the drive waveform generated on the Main board, the PZT selected by the nozzle selector IC on the Printhead pushes the top of the ink cavity, which has ink stored, to eject the ink from each nozzle on the nozzle plate.



Electric poles for CSIC

This electric poles connects the CSIC chip mounted on the ink cartridge. By using this poles, current ink consumption amount data is red out from the CSIC chip. And, the latest ink consumption amount data is written into the CSIC chip.



Nozzle Plate The plate with nozzle holes on the Printhead surface is called Nozzle Plate.



Filter When the ink cartridge is installed, if any dirt or dust around the cartridge needle is absorbed into the Printhead, there is a great possibility of causing nozzle clog and disturbance of ink flow, and alignment failure and dot missing finally. To prevent this problem, a filter is set under the cartridge needle.



Ink Cavity The ink absorbed from the ink cartridge goes through the filter and then is stored temporarily in this tank called “ink cavity” until PZT is driven.

Figure 2-2. Nozzle layout

CSIC chip

Nozzle selector board

The Printhead has the electric poles to store the ink consumption amount data into the CSIC chip mounted on the ink cartridge. By storing the ink consumption amount data, this printer can detect the ink consumption status, such as ink low/end condition.

Ink cartridge

Needle

Elect ric poles for CSIC

The basic operating principles of the Printhead, which plays a major role in printing, are the same as the previous printer (Stylus COLOR 680); on-demand method which uses PZT (Piezo Electric Element). In order to uniform the ejected ink amount, the

* Head ID for the Prin th e a d

is stored to the EEPROM.

Printhead has its own Head ID (11 digits code for this Printhead) which adjusts PZT voltage drive features. So, you are required to store the Head I D pasted on the Printhead into the EEPROM by using the Adjustment program when replacing the Printhead, the Main board, the Printer mechanism with new one. (Note : there are no resistor arrays to determine the Head ID on the Main board.) And then, based on the stored Head ID into the EEPROM, the Main board generates appropriate PZT drive voltage.

Following explains the basic components for the Printhead.

Operating Principles Overview 24

EPSON Stylus C60 Revision A

2.1.2.1 Printing Process

This section explains the process which the Printheads of On-Demand inkjet printers eject ink from each nozzle.

Normal state :

When the printing signal is not output from C418 Main board, or the PZT drive voltage is not applied, the PZT does not change the shape. Therefor e, the PZT does not push the ink cavity. The ink pressure inside the ink cavity is kept normal. (Refer to Figure 2-4 : Normal state)

Ejecting state :

When the print signal is output from the C418 Main board, the nozzle selector IC located on the Printhead latches the data once by 1-byte unit. Based on the drive waveform (common voltage) generated on the Main board, the PZT selected by the nozzle selector IC pushes the top of the ink cavity. By this operation, the ink stored in the ink cavity is ejected from nozzles. (Refer to Figure 2-4 : Ejecting state)

2.1.2.2 Printing Method

For printing dot system, the Stylus C60 has the following two kinds of printing mode.



Multiple shot printing



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.



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 mo de uses n ormal do t, and the number of dot shot varies from 1 shot to maximum 3 shots depending on the print data to enable to output sharp image even in a low resolution.



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 la rge dot compose this mode. The pri nting dot size varies according to the print data and this mode enab les to output even sharper image on exclusive paper.
