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.

3.2 Adjustment After Replacing Parts

The following describes the adjustments that are required after each part replacement. Adjustment and correction of color registration are always required for each part replacement.

Replaced Part

LED Head Drum Cartridge (Y, M, C, K) Fuser Unit Belt Cassette Assy PU (K7N Board) CU (TIG board) Shutter Media Thickness Sensor Assy

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.

))

While holding SWs After MAINTENANCE MENU is displayed on LCD, the display changes to USER.

Press SW ODA * appears on the lower display. Press SW Confirm the setting by pressing SW

Printer restarts, and comes up with the destination changed.

))

, and

down, turn on printer.

2 to select a destination.

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:

(1) Press (2) Press (3) Press

The auto density adjustment will begin.

Perform the task when the printer is not in operation. Do not perform during warm-up.
