Page 4 Safety Prevention of Physical Injury Before disassembling or assembling parts of the machine and peripherals, make sure that the machine and peripheral power cords are unplugged. The plug should be near the machine and easily accessible. Note that some components of the machine and the paper tray unit are supplied with electrical voltage even if the main power switch is turned off.
Page 5 small children. 19. For machines installed with the anti-tip components: The anti-tip components are necessary for meeting the requirements of IEC60950-1, the international standard for safety. The aim of these components is to prevent the products, which are heavy in weight, from toppling as a result of people running into or leaning onto the products, which can lead to serious accidents such as persons becoming trapped under the product.
Page 6 Handling Toner • Work carefully when removing paper jams or replacing toner bottles or cartridges to avoid spilling toner on clothing or the hands. • If toner is inhaled, immediately gargle with large amounts of cold water and move to a well- ventilated location.
Page 7 Laser Safety The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field.

7.Detailed Descriptions Laser Exposure Overview Part name LDB (C/M) Lens Polygon mirror motor Synchronizing detector board LDB (K/Y) Mechanism Composition This machine uses two LDB units and one polygon mirror motor [A] to produce latent images on four OPC drums [B] (one drum for each color toner). There are two hexagonal mirrors.
Page 274 7.Detailed Descriptions LD Safety Switch A safety switch stops the machine operation when the front cover or the top cover is opened. As a result, the relay on the PSU cuts off the power supply (+5V) to the two LD boards. (The circuits go through the EGB.) This system prevents unexpected laser emission, and ensures user safety and technician safety.

Page 276: Aio Cartridge
7.Detailed Descriptions AIO Cartridge Overview This machine uses the AIO (All In One) system. Each AIO consists of the waste toner tank, print cartridge part, development unit part, and OPC part. This gives the user easy replacement procedures and helps to make the engine module more compact. The waste toner bottle is smaller than other full- color printers because the waste toner from the OPC is collected in the waste toner tank of each AIO.
Page 277: Mechanism
7.Detailed Descriptions Mechanism Drive The black drum motor [A] drives the gear for the black AIO. The color drum motor [B] drives the color gears for the cyan, magenta and yellow AIOs through gears. Each of these gears engages with a gear [C] in the OPC, and this gear drives the rollers in the AIO through other gears.
Page 278 7.Detailed Descriptions OPC Charge and Cleaning This machine uses a charge roller [A]. The charge roller gives the drum surface a negative charge. The high voltage supply board, which is at the left side of the machine, applies a dc and ac voltage (at a constant current) to the roller. The ac voltage helps to make sure that the charge given to the drum is as constant as possible.
Page 279 7.Detailed Descriptions toner up to the waste toner container [E]. The collected waste toner is moved to the left side of the AIO by the waste toner collection coil [D]. A flexible sheet [F] separates the unused toner area from the waste toner area. The waste toner area becomes larger when toner is consumed.
Page 280 7.Detailed Descriptions Development This machine does not use developer, so a TD sensor is not necessary. In each AIO unit, the toner supply roller [A] supplies toner to the development roller [B]. Electrostatic attraction generated by the friction between the toner supply roller and development roller moves toner to the surface of the development roller, and the development blade [C] makes sure that the layer of toner on the development roller has an even thickness.
Page 281: Process Control
7.Detailed Descriptions Process Control Process Control Flow Process control adjusts imaging processing conditions as required to maintain constant, uniform image density. Process control comprises toner coverage control and MUSIC (Mirror Unit Skew and Interval Correction) which ensures consistent color overlay. Toner Coverage Control The machine uses the temperature and humidity readings of the temperature/humidity sensor to determine the correct bias for the application of charge to the surface of the drum to ensure that...

The center TM/P sensor is also used to detect the amount of toner coverage in the patterns on the drum for toner coverage process control.

Page 285 7.Detailed Descriptions The black drum motor [A] controls the transfer belt drive roller [B]. The belt tension roller adds tension to the transfer belt to help to turn this belt. The image transfer belt rollers [C] are charged from terminal plates to move the toner from the OPCs to the image transfer belt.
Page 286 7.Detailed Descriptions ITB Cleaning Unit The ITB cleaning blade [A] in the cleaning unit removes remaining toner on the image transfer belt after image transfer to the paper. The toner collection coil [B] moves the collected waste toner to the outlet for the waste toner bottle.
Page 287 7.Detailed Descriptions The transfer roller [A] is always pressed against the image transfer belt by pressure from a spring. The transfer roller moves toner images [B] from the transfer belt to the paper. When a sheet of paper [C] goes between the transfer roller and the transfer belt, the transfer roller turns with the paper. The transfer unit has a discharge plate [D] above the transfer roller.

7.Detailed Descriptions Paper Feed Overview Part name Part name Paper feed roller Paper height lever Registration sensor feeler Separation pad Registration roller Paper end sensor (S3) This machine has a paper tray (250 sheets) and a bypass paper feed (single sheet). The paper feed mechanism uses a friction pad system.
Page 293 7.Detailed Descriptions The paper feed roller feeds a sheet of paper to the registration roller. When the registration sensor [F] detects a sheet of paper, the machine makes a paper buckle at the registration roller to correct paper skew. After that, the registration clutch turns on, and then the registration roller transports a sheet of paper to the transfer roller unit.
Page 294 7.Detailed Descriptions while a sheet of paper is set in the bypass tray, an initial jam occurs. When manual feed printing continuously, set the second sheet after the first sheet is printed.
