Stylus Pro XL+ Service Manual Operating Principles 2.1 OPERATING PRINCPLES - OVERVIEW This section describes the operating principles of the printer mechanism and the electrical circuits of the Stylus Pro. 2.2 OPERATING PRINCIPLES OF THE PRINTER MECHANISM 2.2.1 Principles of the Printing Operation The printing mechanism for the Stylus Pro XL+ has a drop-on-demand ink jet system, similar to the system in all other EPSON ink jet printers.
Operating Principles Stylus Pro XL+ Service Manual 2.3 OPERATING PRINCIPLES OF THE ELECTRICAL CIRCUITS The Stylus Color Pro XL+ contains the following circuit board units: ❒ ❒ ❒ C184 MAIN board (main control circuit board). C137 PSB/PSE board (power supply circuit board). This board is the same as Stylus Color’s C137 PNL (control panel board). This board is similar to Stylus Color’s.
Stylus Pro XL+ Service Manual Operating Principles 2.3.2.1 Reset Circuits The C184 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 (logic line), using reset IC PST592D (IC9), and outputs a reset signal to the CPU (IC1) and the E05E21 gate array (IC2) when the voltage level drops below +4.2 V.
Operating Principles Stylus Pro XL+ Service Manual 2.3.2.2 Sensor Circuits The following sensor circuits enable the C184 MAIN board to monitor printer mechanism status: HP sensor A photocoupler-type HP (home position) sensor is attached to the surface of the printer mechanism to detect the carriage home position. A HIGH level from the signal indicates that the carriage is in home position.
Stylus Pro XL+ Service Manual Operating Principles 2.3.2.3 Carriage Motor Driver Circuit Carriage motor driver IC SLA7043 (IC15) outputs a constant current to drive the carriage motor in the printer mechanism. Gate array E05B21 (IC2) decides the motor phase and speed, and then it sends a signal to the carriage motor driver IC (SLA7043), using the 4-bit serial transmission line. The first bit indicates the direction of motor rotation.
Operating Principles Stylus Pro XL+ Service Manual 2.3.2.4 Paper Feed Motor Driver Circuit The paper feed motor for this printer drives the following mechanisms: ❒ ❒ ❒ Paper feed mechanism Paper pickup mechanism Pump mechanism Driver IC SLA7043 (IC14) drives the paper feed motor by a constant current. The principle of operation is same as for the carriage motor driver circuit. However, the paper feed motor drives not only the paper feed mechanism but also the pump unit. (Refer to Section 2.3.2.4.
Stylus Pro XL+ Service Manual Operating Principles 2.3.2.5 Printhead Driver Circuit The printhead driver circuit for this printer is composed of the following two parts: ❒ ❒ Common driver circuit (common drive pulse generation) Head driver circuit (nozzle control built on the printhead) The common driver circuit is hybrid IC H8D2778A on the C184 MAIN board. The head driver circuit is IC SED61110D0A on the printhead unit itself. The printhead drive signals are output from gate array E05B21.
Operating Principles Stylus Pro XL+ Service Manual Common Driver Signals The common driver control signals consist of the common voltage control signals (SBDAT/SCDAT, SSTB, SCLR, SCLK) and the common drive pulse generation signals (BH1C0/CH1C0, BH1C1/CH1C1, BH1D/CH1D, BHDIS/CHDIS).
Stylus Pro XL+ Service Manual Operating Principles Nozzle Select Signals The nozzle select signals are output from gate array E05B21 to SED6110D0A on the head unit to select the printhead nozzles. Nozzle select data (BHDAT/CHDAT) is HIGH for selected nozzles and LOW for unselected nozzles. Nozzle select data translation timing is controlled by 64 clock signals (BHCLK/CHCLK), one for each nozzle.
Operating Principles Stylus Pro XL+ Service Manual Normal Dot Versus EPSON Micro Dot Printing Mode The Stylus Color Pro XL+ can eject ink in two different modes (normal print mode and EPSON Micro Dot Mode). These modes are the same as the modes used in the Stylus Color II/Stylus Color IIs. (Refer to Section 2.2.1.) However, EPSON Micro Dot Printing in the Stylus Color II and Stylus Color IIs can be used only for printing with black ink.
Stylus Pro XL+ Service Manual Operating Principles 2.4 INK SYSTEM MANAGEMENT This section explains how the ink system is managed to protect the printhead and the ink supply system and to ensure high-quality output. Ink system operations are controlled by the following counters: ❒ Protect counter ❒ Ink consumption counter 2.4.1 Counters EEPROM 93C46 (IC11) on the main board stores the counter values used for controlling ink system operation. 2.4.2.
