[8] Simulation and diagnostics

1. Simulation

(1) Introduction

Simulation are used to do the following:

• To operate any functional block independently to check its func-

tion.

• To adjust the machine.

• To cancel troubles.

• To set up functions.

(2) Purpose

Simulation are used to help repair and adjust the machine. When the PAUSE key is pressed in a course of a simulation being

executed, the simulation is interrupted with the copy number window turned off and the copier becomes ready to accept entry of a simulation number.

*1: If the key was pressed for more than five seconds, it may not go

into the simulation mode.

(3) Simulation execution procedure

List of the test commands

Press the CL EAR key.

Pres s the PAUSE key.

As the copy number window number disapp ea rs , th e co n tr ol be co mes re ad y for ent ry of a si mula ti on nu mber .

*2: Further operation may be needed depending on the kind of

simulation.

*3: One of the next methods is required to cancel the simulation as

it varies according to the simulation. The machine then starts from the state immediately after power on.

— Other than simulation 7

The simulation is canceled when the CLEAR ALL key is pressed.

— Simulation 7

One of the following operation cancels the simulation execution.

1. Power switch off.

2. Press the CLEAR → PAUSE → 0 → PAUSE → CLEAR ALL keys.

— Simulation 14

The simulation 14 is used to clear the memory contents (H2, H3, H4) that have been stored. After the simulation 14 has been executed, the diagnostic is automatically terminated.

— Special keys

CLEAR ALL key: Simulation mode → normal mode. PAUSE key: Execution of simulation is interrupted.

CLEAR key: Clears the copy number window.

— The diagnostic is automatically terminated after the doorswitch

operation "ON → OFF → ON", except "H" and "U2" code.

Press the 0/

◊ KEY.

Enter th e re qu ir ed simula tion number on the keypad.

After ent erin g a tw o-di gi t nu mber , t he simulation number comes displayed on the copy number window.

Is there

any subsequent

code?

YES

08 Lens characteristics entry (at a time of lens replacement)

Because each lens has a variance in focal distance, the lens moving distance in any zoom mode must correspond with the focal distance of the lens. The zoom ratio varies proportionate to the variance of the lens focal distance. To avoid focus problem, the class of the lens focal distance (refer to chart on page 7-11) is stored in the memory using the test command. In a variable zoom mode, the lens moving distance that corresponds to the lens focal distance is obtained on the basis of the data so as to produce the accurate zoom copy.

48 01 Front/rear direction zoom ratio adjustment (refer to [8]-5-(6) for the lens type value.

Used to set the No.4/5 mirror home position (focal adjustment) and to adjust the zoom ratio of the copy in the vertical direction (from front to rear). There are two kinds of test command 48-01 of which are described as follows.

1-1. Horizontal copy zoom ratio standard value input method (at a time of lens or main PWB

replacement) When this simulation is executed, the already set value or "40" is displayed. Substitute the value of "O.L" shown on the label attached to the lens with the formula value.

[7]-8-(1)

[8]-3-(3)

40 – [(value of O.L.) x 5] = standard value of correction Ex: 40 – (+1.2 x 5) = 34

1-2. Use this test command to adjust the horizontal zoom ratio. Change the value entered in "1-1" to

change.

2-1. No.4/5 mirror home position standard value input (at a time of lens or main PWB replacement).

When this simulation is executed, the already stored value or "42" is displayed. Substitute the value of "O.L" shown on the label attached to the lens with the formula value.

[7]-8-(2)

[7]-9-(4) 42 – [(O.L value) x 10] = standard value of correction Ex: 42 – (+1.2 x 10) = 30

2-2. To adjust the resolution, change the value entered at "2-1" using this test command.

When the No. 4/5 mirror reference value is "+" from the center value "50", the mirror is shifted away from the lens to lengthen the light path. When it is "–", the mirror is shifted to the lens to shorten the light path. The value is calculated in this manner.
