2.1 OVERVIEW This section de scribes the operating p rinciples of the p rinter mechanism and the ele ctrical circuits of the Stylus P ro XL. 2.2 OPERATING PRINCIPLES OF THE PRINTER MECHANISM The Stylus Pro XL printer mechanism is composed of the printhead unit, paper fe ed mechanism, carriage drive mechanism, pump mechanism, and various sensors.
2.2.1 Printer Mechanism The printer me chanism of this printer uses a drop-on-demand ink jet system similar to the system used on all othe r EPSON ink jet printers. However , the printhead in this system is comp letely redesigned to make it more compact and ensure a h igh level of reliability.
Principles of the Printin g Operation The printhead operates in one o f two modes to eject ink from each nozzle: ❏ Normal state No electrical charge is applied to the MLP (Multi-Layer Piezoelectric) elem ent attached to the back of the cavity, and pressure inside the cavity is kept at a constant le vel.
Micro Dot Printing mode The Stylus Pro XL printer has a special printing mode, called “Micro Dot Printing mode”. This printing mode can be selecte d by a command from the host computer. Using the Micro Dot printing mode can imp rove the quality of output.
2.2.2 Carriage Drive Mechanism The timing belt attached to the base of the carriage unit is driven by the carriage motor, causing the carriage unit to move along the carriage guide shaft left to right, or vice versa.
2.2.2.1 Platen Gap Adjust Lever The platen gap adjust leve r, which is attached to the carriage unit, needs to be set to an appropriate position for the paper thickness. To change the platen gap , put the printer in the P AUSE state; then press the Font button, while holding down the Alt button.

2.2.4 Ink System This printer’s ink system is composed of the following mechanisms: ❏ Ink cartridge ❏ Pump mechanism ❏ Cap mechanism ❏ Waste ink drain tank ❏ Wiping mechanism The figure below shows a diagram of the ink system.
2.2.5 Pump Mechanism The paper fe ed motor drives the p ump mechanism when the transmission gear is moved to the position where the paper feed motor engages the pump mechanism gear trains, when the carriage unit is at the ink system home position. The figure below shows a block d iagram of the pump mechanism.

2.2.6 Cap Mechanism The cap m echanism prevents the p rinthead nozzles from drying and keeps bubble s from forming inside the nozzle while the printer is not in use. The printer performs this operation autom atically when print data is not received or when the printer power is turned off during printing or ink system operations.
2.3 OPERATING PRINCIPLES OF THE ELECTRICAL CIRCUITS The Stylus Pro XL contains the following circuit board units: ❏ C162 MAIN Board (main control circuit board) ❏ C137 PSB/PSE Board (power s upply.
The figure below shows a block diagram of the power supply circuit (C137 PSB/PSE). The power switch is equipped with a secondary circuit that allows the CPU to rem ain active for a while after the printer is turned off. This allows the printhead to return to the capping position after power is off.
2.3.2 Operating Principles of the Main Control Circuit The main control circuit of this printer is the C162 MAIN Boa rd. This circuit is controlled by the 16-bit CPU H8/3003 (IC1), running at 14.7456 MHz. This CPU has a unique architecture capable of handling data on the data bus at e ither an 8-bit or 16-bit bus width.
2.3.2.1 Reset Circuits The C162 MAIN Board contains 2 reset circuits: the +5 V monitor reset circuit a nd the +35 V monitor reset circuit. The +5 V monitor reset circuit monitors the voltage level of the +5 V line, using reset IC PST592D (IC12), and outputs a r eset signal to the E05A96 gate array (IC2) when the voltage level drops below +4.
2.3.2.3 Carriage Motor Drive Circuit The carriage motor drive IC SLA7041MS (IC15) outputs a constant current to drive the carriage motor for the printer mechanism. Gate array E05A96EA (IC2) decides the motor phase and speed and then sends a signal to the carr iage motor driver IC (SLA7041MS) using the 4-bit serial transmission line.
The following figure shows the cont ents of the four-bit serial data and how this data transacts with the SLA7041MS driver. The step time of the reference voltage is determined by the interval time of the STROBE pulse.
2.3.2.4 Paper Feed Motor Drive Circuit The paper feed motor for this printer drives the following mechanisms: ❏ Paper fee d mechanis m ❏ Paper pickup mechanism ❏ Pump mechanism Driver IC SLA7041MS (IC14) drive s the paper feed motor by a constant current.
2.3.2.5 Printhead Drive Circuit The printhead drive circuit for this printer is compose d of the following two parts: ❏ Common drive circuit (trapezoidal drive pulse generation) ❏ Head drive circu.
Micro Dot Printing Mode The Stylus Pro XL printer has a special printing mode, calle d “Micro Dot Printing Mode.” This printing mode can be selected by command from computer. Using Micro Dot Printing Mode can improve the qua lity of output. In Micro Dot Printing Mode, the ink dot size becomes smaller than the normal dot size.
2.3.2.6 DMA Controller Data from the host computer is received automa tically by the STB signal via the external Centronics interface. The data is inp ut to the input buffe r on the DRAM (IC5). At this time, E05A96 detects the rising edg e of the external STB signal and outputs the STBDMA (strobe DMA request) signal to the CPU.
2.3.2.7 DRAM Refresh Controller The H8 CPU is equipped with a refresh controller in the internal controller. This CPU can contact the 16-bit-long IC5 DRAM, which is a 2 CAS type. The following table lists the junction method between the H8 C PU and the 2 CAS DRAM.
2.4 INK SYSTEM MANAGEMENT This section explains how the ink syste m is controlled to protect the printhead and ink supply system and to ensure high-quality ou tput.
2.4.1 Ink Operations Various ink operations can be performed selectively by the printer. 1 Power On Operation This operation is performed when power is turned on. 2 Cleaning Selecti on Mode This operation cleans each nozzle to ensure that the nozzle fires and that no dots are skipped during printing.
14 Disengage Off Op eration This operation resets the switch lever to the position where it transmits the PF motor drive to the pump mechanism. It also moves the carriage to the flushing position, where the lever is reset to the specified position.
2.4.2 Timer and Counter EEPROM LE93C46 (IC12) on the main board stores certain counter and timer value s used for controlling ink system operation. 2.4.2.1 Protect Counter Protect counter A and Ink Amount C ounter R values are stored in the EEPROM on the main board, and while the printer is on, this data is saved in the RAM on the main board.
