The C7500/C7300 of printers, tandem color electrophotographic page printers, adopt technologies such as an LED array, OPC, dry single-component non-magnetic developing, roller transfer and heat-compression fusing. A black-writing printing method by shedding light on print areas is used.
Figure 2-1-1(600dpi) provides the block diagram of the printer.

(1) CPU
The CPU is PowerPC750CXe, a 64-bit bus RISC processor, which inputs an 100-MHz CLK (= BUS CLK), and operates at 450MHz that is 4.5 times the input.
(2) Cache
PPC750Cxe has its cache only inside of it. Speed: Same as CPU Core CLK speed Capacity: Primary Cache: 32 K bytes in D-cache capacity, 32 K bytes in I-cache capacity Secondary Cache: 256 K bytes
(3) ROM
ROM is to be inserted into the two 168 pin DIMM slots. The slot A is for program ROM and the slot B is for Japanese kanji fonts. The slot C is not assigned.
(4) RAM
RAM is to be inserted into the three 168 pin DIMM slots. The DIMMs must be fitted in descending labeled type No. order into the slots 1, 3, 2 and 4.
SDRAM DIMM Specifications:
Speed: PC133 or more Capacity: 64/128/256/512 MB Configuration: Without parity. Without ECC. SPD information is required.
(5) EEPROM
EEPROM, an 8-pin DIP package, is to be inserted into the IC socket. The EEPROM is of 16 Kbits for 3.3V power supply, and settings for controlling the controller block are stored in it.
(6) Flash ROM
A 4Mbyte flash ROM is surface-mounted on the TIG board. The flash ROM is composed of four 2048k-by-16bit chips, and fonts and macros can be stored in it.
(7) Memory Control LSI (CAI)
A 696-pin BGA package ASIC made by NEC. The chip mainly controls a CPU I/F, memory, video data compression and decompression, and a PU-video I/F.
(8) Interface Control LSI (C2)
A BGA package ASIC made by Toshiba, which controls a PU command I/F, operator panel I/F, IDE I/F, Centronics I/F, USB I/F, PCI I/F, EEPROM and a SPD (SDRAM DIMM) I/F.
(9) IDE HDD
An IDE connector is surface-mounted on the board to which an IDE HDD assembled using exclusive molds will be connected. The IDE HDD is used for storing font data, spooling edited video data and registering form data.
(10) PCI Bus Option
Two PCI I/F slots are provided for option board use. The bus, which uses an Oki Data original connector, can accept an Ethernet board.
(11) Host Interface
Standard: Centronics two-way parallel I/F (IEEE-1284-compliant)
USB (USB1.1-compliant)
Additional Board: (connected to PCI BUS)

The engine control block (PU) is controlled by the engine controller board (K71 PWB) which consists of a CPU (MSM66Q577), general LSI chip, flash ROM, EEPROM, pulse motor drivers and a video memory (see Figure 2-3).
(1) CPU
This, a 16-bit CPU with an AD converter (OKI MSM66Q577), controls the entire system.
(2) General LSI
This LSI (UPD65454GD-241-LML, UPD65946GD-137-LML), which is contained in the printer engine control block, incorporates 4 megabits of video memory and has functions such as engine-controller interfacing, LED interfacing, motor control, sensor input, video memory control, main scan color misalignment correction, skew correction and high-voltage power supply control.
AR-C200P Rev.5 15/
(3) MCON LSI
This LSI is used for inport of SENSORs and the cntrols of Pulse Motors,Cluches,FANs and High Voltage Power Suply.
(4) Flash ROM
The flash ROM (29F800-70) is of 8-Mbits, and PU programs are stored in it.
(5) EEPROM
The EEPROM (NM93C66N-NW) is of 4-Kbits, and mounted on the board with an IC socket. Correction values are stored in it.
(6) Pulse Motor Driver
The pulse motor driver (A2919SLBTR, A3955SLBTR,MTD2005) drives the eight pulse motors to revolve the ID and transport media.
(7) SRAM
This SRAM (628100LG-55L) is used as working memory of the CPU.
(8) SDRAM
This SRAM (56V16160T) is used as data memory of the DCON LSI.
2.3 Power Units
There are a low voltage power unit consists of an AC filter circuit, low voltage power circuit and heater driver circuit, and a high voltage power unit organizes a high voltage power circuit.
(1) Low Voltage Power Unit
This circuit generates the following voltages:
Output Voltage Use for
+5 V LED head +5 V Logic circuit power supply, PU CPU +34 V Motor, drive voltage and power supply voltage for high voltage power supply +12 V High voltage power supply, Media Thickness Sensor power supply
(2) High Voltage Power Unit
This circuit generates the following voltages of not less than +34V, which are required for electrophotographic process, according to control sequences from the controller board.
Output Voltage Use for Remark
CH -1000V to 1.4KV+/-50V Voltage to charging roller DB -50 to -300V/ +300V Voltage to developing roller SB -300V to -450V/ 0V Voltage to toner supplying roller TR C: 0KV to 7KV Voltage to transfer roller Variable
K,Y,M: 0KV to 6KV

2. PARTS REPLACEMENT

This section describes the procedure for replacing the parts, assemblies and units in the field. The replacing procedure is given for detachment. To attach, use the reverse procedure.

2.1 Precautions in Replacing Parts

(1) Before replacing the parts, be sure to remove the AC cable and the interface cable.
(a) To remove the AC cable, always use the following procedure.
i) Flip the power switch of the printer off (to “O”). ii) Pull the AC inlet plug of the AC cable out of the AC receptable. iii) Remove the AC cable and the interface cable from the printer.
(b) To connect the printer again, always use the following procedure.
i) Connect the AC cable and the interface cable to the printer. ii) Insert the AC inlet plug into the AC receptacle. iii) Flip the power switch of the printer on (to “I”).
Disconnect
(2) Do not disassemble the printer so long as it operates properly.
(3) Minimize the disassembly. Do not detach parts other than those shown in the replacing procedure.
(4) For maintenance, use designated tools.
(5) Follow the order instructed to disassemble the printer. Incorrect order may damage the parts.
(6) Small parts such as screws and collars tend to get lost, so temporarily place and fix them in
(7) When handling ICs and circuit boards such as microprocessors, ROMs and RAMs, do not use
Connect
their original positions.
gloves that likely to have static.
(8) Do not place the printed circuit boards directly on the printer or the floor.
