Chapter 2 Technical Reference
MultiPASS F20 Chapter 2: Technical Reference 1. COMPONENT LAYOUT 1.1 Parts Layout The parts layout of this machine consists of the scanning assembly, printing assembly and printer.
MultiPASS F20 Chapter 2: Technical Reference The electrical parts are laid out as follows. • SPCNT board ........................................................ Operation panel control, Document scanning control, Printer control, sensor detection • Power supply unit ................................................. supplies power to the units and assemblies • OPCNT board ....................................................... detects keyboard operation and displays machine information • Sensor board .....
MultiPASS F20 Chapter 2: Technical Reference •4 sensors ................................................................ detect unit and assembly statuses Paper edge sensor: Detects the state of paper feeding and delivery. Cover sensor: Detects the state of inner. Carriage encoder film: The sensor mounted to the carriage unit reads the information from the encoder film, thereby detect the state of the carriage unit.
MultiPASS F20 Chapter 2: Technical Reference 2. SCANNER MECHANISM The scanner section scans documents that are to be copied.
MultiPASS F20 Chapter 2: Technical Reference Names and function of parts 1. Contact sensor drive motor The contact sensor drive motor is used to drive the contact sensor. 2. Contact sensor drive belt The contact sensor drive belt is used to covey the driving force of the flatbed motor to the contact sensor. 3. Contact sensor shaft The contact sensor shaft is used to keep the direction of the driving force of the contact sensor. 4.
MultiPASS F20 Chapter 2: Technical Reference 3. PRINTER SECTION 3.1 Overview of the Printer's Mechanical Parts The printer's mechanical parts consist of the BJ cartridge, carriage, purge section, and paper feed section. Each part is explained below.
MultiPASS F20 Chapter 2: Technical Reference 3.1.1 Carriage The carriage holds one BJ cartridge in place. The carriage belt driven by the carriage motor (DC motor) moves the carriage horizontally back and forth across the paper. Regarding the carriage's position control, the initial position is detected when the carriage goes against the right wall which is the home position. After that, the carriage position is detected by reading the pulse from the encoder film.
MultiPASS F20 Chapter 2: Technical Reference 3.2 Paper Feed Section 3.2.1 Paper feed components The auto sheet feeder separates recording paper by rotating the separation roller in the opposite direction of pickup. Compared with other auto sheet feeders, it shows better separation performance.
MultiPASS F20 Chapter 2: Technical Reference 3.2.2 Paper transport section In the printing block, the gap between print paper and the print head is kept at a specific distance by forcing the paper against the platen between the pressure roller and the paper feed roller and also between the spurs and the eject roller. When the paper has been moved as far as the print start position, printing starts on the platen. 3.2.
MultiPASS F20 Chapter 2: Technical Reference 3.3 Ink residual quantity detection The F20 is not equipped with a sensor used to detect the level of ink remaining in its tank. The absence of such a sensor is made up for by counting the dots in a deposit. When these dots reach a specific number, the LCD will indicate a message alerting the user that the ink is running out and prompting replacement of the tank, which must be replaced when the output starts to show fuzzy images or becomes blank.
MultiPASS F20 Chapter 2: Technical Reference 3.4 Purge Section 3.4.1 Purge section functions In order to maintain good printing quality, the purge section maintains the BJ cartridge's nozzles. The purge section's functions consist of capping and cleaning. a) Capping The purge unit's cap is pressed against the print head's face to protect the nozzles from dust, etc., and to prevent the nozzles from drying out. To prevent the capping position from shifting, the carriage is locked in place at the same time.
MultiPASS F20 Chapter 2: Technical Reference 3.4.2 Purge section components Wiper Cap Cleaner Purge Motor Figure 2-8 Purge Section Components a) Purge driving motor The purge motor drives the wiper, carriage lock, and pump. It is a constant-voltage motor operating with a 1-2 phase drive. b) Wiper The wiper consists of a wiper and wiper cleaner. The wiping operation is executed while the carriage is fixed at the purge section. It wipes the print head's nozzle array in a vertical motion.
MultiPASS F20 Chapter 2: Technical Reference 3.5 Ink Suction Amount in the Cleaning Mode The machine has five cleaning modes (A to G). Cleaning is executed for maximum effectiveness and efficiency. The cleaning operation is selected depending on the respective condition. The ink suction operation differs depending on the condition at three occasions: Operation by the user, cover open/ closing, and before printing starts.
Chapter 3 Assembly and Disassembly
MultiPASS F20 Chapter 3: Assembly and Disassembly 1. ATTENTION TO BE PAID DURING ASSEMBLY/ DISASSEMBLY 1.1 Safety Cautions Electrical shock In order to prevent any risk of electrical shock, always be sure to check that the power cord and modular jack have been removed. Also, remove all cables connecting to the computer. When conducting service that requires the main unit to be powered on, be sure to wear some kind of earthing, such as a wrist strap, etc.
MultiPASS F20 Chapter 3: Assembly and Disassembly 1.2 General Cautions Damage due to electrostatic discharge This machine contains contact sensors and printed circuit boards that use ROMs, RAMs, custom chips and other electronic components that are vulnerable to damage by electrostatic discharge. Be careful to avoid any damage from electrostatic discharge when conducting service that requires disassembly.
MultiPASS F20 Chapter 3: Assembly and Disassembly 1.3 Product-Inherent Cautions Prevention of ink-soiling Be careful when handling the BJ ink cartridge nozzle, the ink pad, head cap, head wiper and waste ink pad. Residual ink may soil the main unit, working surfaces, your hands and clothes, etc. The ink is watersoluble, but because it contains pigments, it will not wash out of clothes.
MultiPASS F20 Chapter 3: Assembly and Disassembly 1.5 Transporting the machine If you must transport the machine as when returning it after repair work, be sure to perform the following work: (a) Mount the BJ cartridge (printer head) to the carriage. (b) Turn off the printer so that the carriage locks at the home position. If the BJ cartridge (print head) is not on the carriage, the ink may dry and harden. So even while transporting the printer, leave the BJ cartridge mounted on the carriage.
