1.3.5 Printer Language and Emulation
Printer language: ESC/P2 IBM X24E emulation EPSON Remote
1.3.6 Prevention Hosts from 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 from this kind 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 rest of the input buffer becomes several hundreds of bytes. Finally, the printer is in the busy state continuously when the input buffer is full. USB and IEEE1284.4 on the parallel interface do not require this function.
1.3.7 Auto Interface Selection
The EPSON Stylus Color 980 has three types of interfaces: USB, parallel interface and optional Type-B interface. Each interface can be selected manually in default setting mode or automatically. Manual Selection: One of three interfaces can be selected in default setting mode. Automatic Selection: The automatic interface selection is enabled by the default setting mode. In this automatic interface selection mode, the printer is initialized to the idle state scanning for which interface is to receive data when it is powered on. The interface that receives data first is selected. When the host stops data transfer and the printer is in the stand-by state for a number of seconds, the printer returns to the idle state. As long as the host sends data or the printer interface is busy state, the selected interface is let as it is. The changes to other interface are prohibited during duplex printing.

1.3.7.1 IEEE 1284.4 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. ON: IEEE1284.4 is enabled as initial state. Data sent before the magic string (1284.4 synchronous commands) is discarded. OFF: IEEE1284.4 is disabled and IEEE1284.4 synchronous commands are ignored. Compatible interface is the initial state.

1.5 Error Status
When any of the following status occurs, the printer goes in the error status and stops receiving data, setting the /ERROR signal in the interface to "Low", and Busy signal to "High". During this condition, the printer is in non-printable status. Refer to Section 1.4.3 for detailed LED Panel indicator status and corresponding error types.
1.5.4 No Ink Cartridge
When the printer detects that the ink cartridge has come off, it goes into the No ink cartridge error.
1.5.5 Maintenance Request
When the total quantity of ink wasted through the cleanings and flushing has reached the limit, printer indicates this error and stops printing. The absorber in the printer needs to be replaced with a new one by a service person.
1.5.1 Ink Out
When the printer has run out the most of the ink of any color, it warns of Ink Low condition and keeps printing. When the printer runs out the whole ink of any color, it stops printing and indicates the Ink Out error. User is required to install a new ink-cartridge in this state. Note if an inkcartridge has been taken out, it should never be used again. Reinstalling the used cartridge (not fully filled with ink) upsets the ink level detection and may cause a serious problem in the printhead as a result.

1.6 Printer Initialization
The EPSON Stylus Color 980 is equipped with three types of initialization methods. Power-on initialization The printer is initialized when it is turned on or recognizes the coldreset command (remote RS command). When the printer is initialized, it performs the following: (a) Initializes the printer mechanism. (b) Clears the input data buffer. (c) Clears the print buffer. (d) Sets the default values. Operator initialization This printer is initialized when it is turned on again within 10 seconds after last power off or recognizes the /INIT signal (negative pulse) of the parallel interface. When printer is initialized, it performs the following: (a) Caps the printhead. (b) Ejects a paper. (c) Clears the input data buffer. (d) Clears the print buffer. (e) Sets the default values. Software initialization The ESC@ command also initializes the printer. When the printer is initialized, it performs the following: (a) Clears the print buffer. (b) Sets the default values.

1.7 Component Layout
The main components of the Stylus Color 980 are as follows: 1) Printer mechanism 2) C380 Main board 3) C265 PSB/PSE board 4) C265 panel board 5) C265 relay board
1.7.1 Printer Mechanism
The printer mechanism of the Stylus Color 980 has black and color heads united in one unit which drives larger amount of nozzles (180 nozzles in total) than ever. Also, for a new ink jet printer feature, the printer has succeeded in printing in the acceleration/deceleration areas by reading the slits on the linear scale to improve the throughput. This improvement in throughput mostly depends on the Pump/ASF switching mechanism. In other printers, the gear trains are switched when the trigger lever hits the mechanism along with the carriage's movement. In Stylus Color 980, however, the exclusive solenoid is directly attached to the mechanism instead. With the solenoid which switches drive at a higher speed, the printer can control high-speed paper ejection system: the printer bring the leading edge of the second sheet to the printing position just before ejecting the first sheet. The motors equipped with the printer are CR motor, PF motor, and the Pump/ASF Motor, same as for the Stylus Color 900.

1.7.2 C380 Main Board
The main features of the C380 Main board are as follows. 1. IEEE1284 compliant ECP mode is available Type-B I/F is available 2. USB full-speed is available (at 12 M bps without the hub). 3. All motors (CR motor, Pump/ASF motor, and PF motor) are controlled with the micro step system (using up to 4W1-2 phase excitation mode) and current attenuation mode (First, Slow, Mixed, and Decay). 4. Intensive temperature control of the new type of the printhead: operates the cooling fan using the thermistors and the abnormal temperature detection circuit on the printhead board. C90A09CA, a CPU which is the hub of the C380 Main board, has an internal flash memory with the size of 128 KB. Since the CPU runs with 24 MHz, it can send print data efficiently for a high throughput. The C380 Main board has two independent exclusive ASICs, ASIC1 and ASIC2. The former controls all interfaces but the USB I/F and sensors, while the latter controls the printhead, motors, encoder, and USB I/F. The combined IC (IC8) which has a normal timer IC and EERPOM in one chip also features the printer. Since the EEPROM counts ink consumption at the valuable printing *1, its size has increased to 2 K bit. *1: The valuable dot system, or many-valued dot system, enables the printer to freely fire three different sizes of dots (normal, middle, and small dots) in one raster. In other printers, if the super micro dot mode is once selected through the printer driver, the printers prints only in the selected mode until the current print data is completed. However, the valuable dot system of this printer enables the printer

The C265 PSB/PSE board uses the switching regulator system. Since the C265 PSB/PSE board uses the power switch on the secondary side, it keeps applying voltage to the primary side across the T1. Especially, the heat sink to which the Q1 is attached can not be insulated due to the circuit's formation. Therefore, to avoid an electrical shock, be careful not to touch the heat sink and other metallic parts simultaneously while troubleshooting.

OPERATING PRINCIPLES
EPSON Stylus Color 980
Revision A
2.1 Overview
This chapter describes the operating principles of the printer mechanism and electrical circuits.
2.2 Printer Mechanism Operating Principles
The EPSON Stylus Color 980 has black and color heads united in one unit which includes a total of 480 nozzles: 192 nozzles for black (96 nozzles x 2) and 96 nozzles for each color. This printhead enables the printer to print 3 lines by one pass at 10-cpi printing. Also, new ASF/ pump switching mechanism offers higher throughput with quick feeding motion at continuous printing by combining the trigger solenoid and independent pump/ASF motor. Production of PTS signal using the encoder belt also enables the printer to improve printing accuracy, detect paper jam in the CR operational range, and print during acceleration/deceleration (on normal paper / 360 x 360 dpi only). See Figure 2-1 for the printer mechanism block diagram.
