PROGRAM STARTUP

Start-Up Sequence

Overview

0006-6702 The system software used to control the machine is stored on the HDD.

When the machine is started, the CPU on the main controller PCB reads the system software from the HDD according to the instructions of the boot ROM boot

program, and writes it to the image memory (SDRAM) of the controller PCB.

While the CPU reads the system software from the HDD to the image memory (DRAM), the control panel shows the following screen, using a progress bar to

indicate the progress of the start-up sequence.

Do not turn off the main power while the progress bar is indicated, as access is being made to the HDD. Turning off the power can cause a fault on the HDD (identified

by E602).

Start-Up Sequence

0006-6703 <Boot ROM Area>

-Self Diagnosis Program (interval 1)

The self-diagnosis program is run by the CPU on the main controller PCB when the main power switch is turned on.

The program is used to check the condition of the image memory (SDRAM) and the HDD.

The machine will indicate an error code if it finds a fault while running the program.

-Boot Program (interval 2)

When the self-diagnosis program ends normally, the CPU on the main controller PCB executes the boot program.

The program is used to read the system software from the HDD to write it into the image memory (SDRAM).

<Image Memory (SDRAM) Area> (interval 3)

The system software written by the boot program initializes the various functional blocks (e.g., I/F settings of the main controller).

When all the foregoing ends normally, the machine becomes ready to accept a job

(i.e., the control panel shows the Operation screen, and the LED on the Start key changes from red to green).

Shut-Down Sequence

Overview

0006-8356 If the main power switch is turned off while the machine is accessing its HDD, damage can well occur on the HDD. To avoid such damage, the machine is provided

with a shut-down sequence.

Flow of Operation

The following diagram shows the flow of shut-down operation:

Copying data

On the dialog page Copy data  , you can

start the copying process. Check beforehand in the

status field whether the settings for copying mode,

source, target, and the selected options are right. If

no, go back to the corresponding dialog page by

clicking (repeatedly) [Back] in the lower left corner of

the operating field and adjust the settings. As soon as

you want to start the copying process, click [Start] in

the bottom margin of the operating field. During the

copying process, you can follow the process with the help of the displays described in the following
