*Top margin

The set value is received from the digital copier, and data are m ade according to the set value.

*Left margin

Since the paper size sensor is not set, the digital copier cannot recognize the size and direction of paper which is actually inserted. Therefore, the left margin is set according to the paper size specified in the print data sent from the computer, and print process is performed. If the computer does not specify the paper size, or in the case of the custom size, the left margin is set according to the default paper size.

(7) Print reference

This machine employs the center reference system. Since the digital copier is not provided with the tray size detection feature, formatting and center distribution are performed not by the actual paper size but by the paper size specified by the computer.

[3] UNPACKING AND INSTALLATION

1. Unpacking

<Before installation> For improvement of workability, any part of the description in this

manual may be modified without prior notice. In this case, refer to the service manual.

3. Installation procedure

Turn the main switch of the copier to the "OFF" position and then remove the power plug of the copier from the power supply outlet.

1) Remove the rear cover. Remove the screw, push the portion indicated by the arrow to

unlock the rear cover, and slide the cover to the right to remove it.

2) Cut out the cut-out portion of the rear cover. Cut out the cut-out portion with nippers or the like.

At this time, be careful about the orientation of the nippers so that the cut plane of the rear cover is flat.

2. Parts included

IMC2 PWB (with frame)

screw (golden) M3 x 6: 4pcs.

Installation manual: 1 volume

Rear cover

3) Attach the IMC2 PWB. Fit the two pawls on the rear surface of the IMC2 PWB frame to the

mounting portions of the copier and secure the PWB with the four supplied golden screws M3 x 6.

Take care not to get the cable caught.

4) Connect the IMC2 PWB to the MCU PWB of the copier. Connect the flat cables of the IMC2 PWB to the connectors of the

MCU PWB of the copier so that the shorter cable comes inside and the longer cable comes outside as shown in the illustration. Be careful about the orientation of the flat cable insertion and check that both ends of each cable are securely inserted into the connector. (The terminal surface of each flat cable must have c ontact with the connector terminals.)

4. Installation of additional memory (After installation, proceed to step 5.)

1 Open the two locking clips of the socket. 2 Insert the memory matching the orientation of its notches. 3 Close the locking clips of the socket.

5) Attach the rear cover. Fit the four pawls of the rear cover to the rear cabinet, slide the

cover to the left until it is locked, and then secure the cover with the screw.

As additional memory, use AR-SM5 (sold separately).

Insert the power plug of the copier into the power supply outlet and turn on the power switch. Then, carry out the following procedure.

6) Check the IMC2 PWB. Press the SORT/GROUP key on the operation panel to check that

the SORT mode indicator lights up.

7) Check printing. For installation of the driver software on the computer, see the oper-

ation manual supplied with the copier. Connect the USB cable, carry out printing from the computer, and check that printing can be performed normally.

[4] ELECTRICAL SECTION

The OA982 board mounted on the IMC2 board inputs and outputs image data to and from the MCU board, controls SDRAM memory, and communicates with USB2.0 devices. SDRAM memory is used to store programs and image data as well as for a working area. USB 2.0 devices communicate with a PC through a USB2.0 cable at a rate of 480 Mbps. SDRAM memory can be expanded by using 1BANK SDRAM DIMM (AR-SM5). Communications between the OA982 and the AR-SM5 is held using an ASIC-controlled BUFFER IC (74VCX16244/16245).
