Stylus Pro XL Operating Principles 2.1 OVERVIEW This section describes the operating principles of the printer mechanism and the electrical circuits of the Stylus Pro XL. 2.2 OPERATING PRINCIPLES OF THE PRINTER MECHANISM The Stylus Pro XL printer mechanism is composed of the printhead unit, paper feed mechanism, carriage drive mechanism, pump mechanism, and various sensors. The figure below shows a functional block diagram of the printer mechanism.
Operating Principles Stylus Pro XL 2.2.1 Printer Mechanism The printer mechanism of this printer uses a drop-on-demand ink jet system similar to the system used on all other EPSON ink jet printers. However, the printhead in this system is completely redesigned to make it more compact and ensure a high level of reliability. The figure below shows the structure of the printhead and ink supply system.
Stylus Pro XL Operating Principles Principles of the Printing Operation The printhead operates in one of two modes to eject ink from each nozzle: ❏ Normal state No electrical charge is applied to the MLP (Multi-Layer Piezoelectric) element attached to the back of the cavity, and pressure inside the cavity is kept at a constant level.
Operating Principles Stylus Pro XL Micro Dot Printing mode The Stylus Pro XL printer has a special printing mode, called “Micro Dot Printing mode”. This printing mode can be selected by a command from the host computer. Using the Micro Dot printing mode can improve the quality of output. In Micro Dot Printing mode, the ink dot size became to be smaller than the normal dot size. 2-4 REV.
Stylus Pro XL Operating Principles 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. The carriage drive motor on this printer is a 4-phase, 200-pole, hybrid-type stepping motor mechanism, allowing the printer to stop the carriage or change the carriage movement at any position.
Operating Principles Stylus Pro XL 2.2.2.1 Platen Gap Adjust Lever The platen gap adjust lever, 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 PAUSE state; then press the Font button, while holding down the Alt button. The carriage unit moves the platen gap position automatically. Table 2-3.

Operating Principles Stylus Pro XL 2.2.6 Cap Mechanism The cap mechanism prevents the printhead nozzles from drying and keeps bubbles from forming inside the nozzle while the printer is not in use. The printer performs this operation automatically when print data is not received or when the printer power is turned off during printing or ink system operations. (The secondary circuit for the power switch allows this operation to be performed.
Stylus Pro XL Operating Principles 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 supply circuit board) C137 PNL (control panel board) In addition to the circuit boards above, part of the printhead drive circuit is built on a separate circuit board installed in the carriage unit; the printhead is attached directly to this board.
Operating Principles Stylus Pro XL 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 remain active for a while after the printer is turned off. This allows the printhead to return to the capping position after power is off. The CPU mounted on the C137 MAIN Board always monitors the PSC (power on/off) signal.
Stylus Pro XL Operating Principles 2.3.2 Operating Principles of the Main Control Circuit The main control circuit of this printer is the C162 MAIN Board. 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 either an 8-bit or 16-bit bus width. Because of this, a 16-bit or 8-bit data bus width-type ROM is used on this board, increasing the internal processing speed.
Operating Principles Stylus Pro XL 2.3.2.1 Reset Circuits The C162 MAIN Board contains 2 reset circuits: the +5 V monitor reset circuit and 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 reset signal to the E05A96 gate array (IC2) when the voltage level drops below +4.2 V.
Stylus Pro XL Operating Principles 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 carriage motor driver IC (SLA7041MS) using the 4-bit serial transmission line. The first bit indicates the direction of the motor rotation.
Operating Principles Stylus Pro XL The following figure shows the contents 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.
Stylus Pro XL Operating Principles 2.3.2.4 Paper Feed Motor Drive Circuit The paper feed motor for this printer drives the following mechanisms: ❏ ❏ ❏ Paper feed mechanism Paper pickup mechanism Pump mechanism Driver IC SLA7041MS (IC14) drives the paper feed motor by a constant current. Its principle of operation is same as for the carriage motor drive circuit. But the driving method is different for paper feed and the pump. Table 2-9.
Operating Principles Stylus Pro XL 2.3.2.5 Printhead Drive Circuit The printhead drive circuit for this printer is composed of the following two parts: ❏ ❏ Common drive circuit (trapezoidal drive pulse generation) Head drive circuit (nozzle control built on the printhead) SED5620D, the 64-bit thermal head driver in the head drive circuit on the carriage, is used as a nozzle selector to drive the printhead nozzles selectively.
Stylus Pro XL Operating Principles Micro Dot Printing Mode The Stylus Pro XL printer has a special printing mode, called “Micro Dot Printing Mode.” This printing mode can be selected by command from computer. Using Micro Dot Printing Mode can improve the quality of output. In Micro Dot Printing Mode, the ink dot size becomes smaller than the normal dot size.
Operating Principles Stylus Pro XL 2.3.2.6 DMA Controller Data from the host computer is received automatically by the STB signal via the external Centronics interface. The data is input to the input buffer on the DRAM (IC5). At this time, E05A96 detects the rising edge of the external STB signal and outputs the STBDMA (strobe DMA request) signal to the CPU.
Stylus Pro XL Operating Principles 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 CPU and the 2 CAS DRAM. Table 2-10. Junction Method (CPU — 2 CAS DRAM) CPU 2 CAS DRAM HWR UCAS LWR LCAS CS3 RAS RD WR The method of the DRAM refresh is used only for the CAS before RAS cycle method.
Operating Principles Stylus Pro XL 2.4 INK SYSTEM MANAGEMENT This section explains how the ink system is controlled to protect the printhead and ink supply system and to ensure high-quality output.
Stylus Pro XL Operating Principles 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 Selection Mode This operation cleans each nozzle to ensure that the nozzle fires and that no dots are skipped during printing. Cleaning selection is performed by pressing the cleaning switch (Alt + Load/Eject or Economy/Condensed) while the printer is in PAUSE status.
Operating Principles Stylus Pro XL 14 Disengage Off Operation 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. 15 Micro Absorbing Operation When the cartridge is removed, it is possible for a small amount of air to form small air bubbles that can block the ink from the nozzle.
Stylus Pro XL Operating Principles 2.4.2 Timer and Counter EEPROM LE93C46 (IC12) on the main board stores certain counter and timer values used for controlling ink system operation. 2.4.2.1 Protect Counter Protect counter A and Ink Amount Counter 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. ❏ Protect Counter A 1. Power On (Micro): This counter is used to manage the total amount of drained ink.

Stylus Pro XL Adjustments 4.1 OVERVIEW This section describes adjustments required when the printer is disassembled and assembled after repair. Since this printer has both a black and color head, it needs new adjustments not required for previous printers. Refer to the following table to perform the appropriate adjustments. WARNING ❏ Always perform the adjustments in the order indicated. ❏ After performing steps 1-5, perform a cleaning operation for the black and color printheads.
Adjustments Stylus Pro XL 4.1.1 Destination Data Writing Operation The setup value that specifies the printer destination is stored in the EEPROM on the C162 MAIN board. Therefore, this setup value must be written into the EEPROM when the MAIN board or EEPROM chip is replaced. CAUTION Before writing the destination data writing, set the interface to parallel. 1. Connect the PC to the target printer using a parallel interface cable and turn the printer on. 2.
Stylus Pro XL Adjustments 4.1.2 Bi-D (Bidirectional Printing) Alignment Adjustment The bidirectional alignment is required when the printer mechanism, main board, or printhead (board) is replaced. Performing this adjustment determines a compensation value to rectify any deviation in the print position.
Adjustments Stylus Pro XL 4.1.3 Head Gap Adjustment (Black and Color Head) The head gap adjustment is required when the printer mechanism, main board, or printhead (board) is replaced or diassembled. This adjustment calibrates the head drive timing between the black and color head. If this adjustment is not made, the vertical alignment will not be completed. 1. Connect the PC to the target printer, and turn the printer on. 2. Execute BASIC on the PC and run the program “VERxxx.BAS.” 1.
Stylus Pro XL Adjustments 4.1.4 Black Head Angle Adjustment The black head angle adjustment is required when the black head is replaced or disassembled. If this adjustment is not correct, a white banding problem may occur, or the color head timing may not match the black head timing. The following figure illustrates the black head angle adjustment. The black head angle is adjusted with linear and angular spacers.

Confirm the angle by performing the steps 1 to 6 again, and if the angle is wrong, perform the adjustment again until the head angle is correct. WARNING ❏ The angular spacer comes in five thicknesses. Continue performing this adjustment, by changing the black head angle is correct.
Stylus Pro XL Adjustments 4.1.5 Black - Color Head Vertical Adjustment This adjustment calibrates the vertical position between the black head and the color head. Align the top nozzles (both nozzle #1 on the black head and nozzle #1 on the color head). You can make this adjustment by using only the linear spacers for the black head. This adjustment is required when the black head or the color head is replaced or disassembled. The following figure illustrates this adjustment.
Adjustments 4. Stylus Pro XL In Figure 4-10, the vertical position is correct when both the magenta line and the black line are aligned (as shown in position OK (0)). If the vertical position is correct, turn off the printer. If the black and magenta lines are not aligned, perform the vertical adjustment as described in steps 5-10. WARNING ❏ The number shown in the sample indicates the thickness level compared to the current linear spacer. (See * .
