(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.

SHARP

Three modes from Level 1 to Level 3 are in the engine maintenance mode. Level 1 is a mode that checks the media transport and basic movement of the print system. Level 2 checks the counter for consumables and tests the correcting function of color displacement, and is a mode that does not require special knowledge. Level 3, on the other hand, requires special knowledge for handling the process parameter setting and is contained in the independent experimental element of PU. Basically, levels other than Level 1 should not be used.

Not required Not required. Not required. Not required. Re-mounting the EEPROM used on the board before the replacement. *Note Re-mounting the EEPROM used on the board before the replacement. *Note Setting the correction value of the calibration chip for detecting density. Adjusting paper thickness detection sensitivity and checking media thickness detection value setting.

* Note:1. When the EEPROM of PU (K7N board) is replaced to a new one, color balance must

be adjusted.

* Note: 2. When the EEPROM of CU (TIG board) is replaced to a new one, the Destination

Setting must be adjusted.

3.2.1 Precautions in replacing the engine control board When replacing the engine control board , remove the EEPROM from the old board

and mount it on a new board (for errors other than those of engine EEPROM). When SERVICE CALL xxx (Engine EEPROM Error) is displayed on the operator panel, the EEPROM must be replaced with a new one. In this case, perform the operation described in section

3.2.2.

Adjustment

3.2.2 Precautions in replacing EEPROM When the EEPROM is not removed from the board and placed on the new board at the time of

engine controll board replacement, the Version Read function (fuse cut) is disabled. The printer must be switched from the factory mode to the shipping mode by the PJL command.

[Description]

1. Sending of an appropriate PJL file to the printer to place it in Shipping mode

2. Sending of a repower-on or reboot command (PJL file) to complete the setting [Procedure]

At the MS-DOS prompt, perform the following steps:

1. Enter Copy /b Pjl_ship.bin prn and hit <Enter>.

2. Enter Copy /b Pjl_reboot.bin prn and hit <Enter>, or power the printer off and on. [Pjl Files Required]

1. Pjl-ship.bin

2. Pjl-reboot.bin

Note:

Life data for consumables such as belt, toner, and ID is cleared when replacing EEPROM, therefore, be cautious as there will be a tolerance in life management upon replacing the unit in the future. The following count will be cleared when replacing EEPROM. Other than Total Sheets Feed is cleared when each unit is replaced, therefore, the tolerance will be cleared at that point.

3.2.3 Replacing EEPROM after replacing the TIG board When replacing the TIG board, remove EEPROM from the board used by the user and set it to the

replaced board. (This is to pass on the user set contents and font install data to the new board.) Furthermore, if the user’s EEPROM cannot be used due to damages, use the EEPROM on the new board. In this case, the new board and EEPROM should be set with destinations.

3.2.4 Destination Setting (Checking Metod: Printing Demo Page) The destination setting of each main control board, which takes on ODA by default, must be set,

at the time of printer shipment, to correspond to the destination of the printer equipped with the board. Japan indirect sales, ODA, OEL and APS maintenance boards are to be shipped with the destination setting left at its default.

Setting on Operation Panel: Powering up each printer in maintenance mode and then setting its destination are made.

Description: Each of Japan domestic and over seas AR-C200P uses a common ROM. Destination setting must be made for the common ROM to be used in the printers to various destinations (the setting in the ROM default to ODA). Setiings are stored in TIG board' s EEPROM. Maintenance boards are to be shipped with the destination setting at its default and, when Settings are stored in TIG board' s EEPROM.

3.2.5 Recovery Flash ROM data on TIG board A 4MB Flash ROM that enables a user to register an arbitrary file is installed on the TIG board.

When a TIG board has to be replaced, print a file list of the information menu and check the registered files before replacing the board. Re-register necessary files when the TIG board is replaced.

3.3 Adjusting the Density

The auto density adjust mode is set to [Auto] when the printer is delivered, however, problems may occur upon using the printer if the mode is set to [Manual]. Perform the procedure when the density is improper.

Note:

3.4 Paper Thickness Detection Sensitivity Adjustment and Media Thickness Detection Value Check

Outline:

The sensitivity of a micro displacement sensor used for detecting media thickness varies from one to another. Therefore, to ascertain the sensitivity in advance, check the output value of the sensor by passing media of known thickness through the printer equipped with the sensor. The sensitivity is fixed based on the output value.

Adjustments must be made when the paper thickness sensor, the registration roller and the PU board are replaced. By passing, from the multipurpose tray, four sheets of paper whose thickness has been measured with a micrometer (MDQ-30M, MDQ-30), the correction value for media thickness sensitivity is automatically set with the first three sheets. Check the media thickness detection value with the fourth sheet. Media: Transparency (42404301) Paper thickness difference: Within ±10µm
