Purpose

Operation test/check

Function
(Purpose)

Used to check the warm up time and the operation of all the units and to make aging with copying. Each section
can be checked during copying.

Operation

Operation/
Procedure

1) After completion of simulation, warming up is started.

2) Counting is made every second and the count value is displayed.

3) After completion of warming up, counting is stopped and the ready lamp is lighted.

4) Press the clear key. (Once)

5) Set the copy quantity.

6) Press the start key. 

Copying is made repeatedly to make the set quantity of copy.

Purpose

Operation test/check

Function
(Purpose)

Used to check the warm up time and the operation of all the units and to make aging with copying. Each section
can be checked during copying. (In this simulation, the detection functions of paper presence/empty and a paper
jam are disabled.)

Operation

Operation/
Procedure

Basically the same operation is performed as SIM 7-1. However, paper empty or presence and paper jam are
ignored.

Purpose

Operation test/check

Function
(Purpose)

Used to check the warm up time and the operation of all the units and to make aging (intermittent operation) with
copying. Each section can be checked during copying.

Section

Others

Item

Operation/
Procedure

Basically the same operation is performed as SIM 7-1.
Similarly with SIM 7-1, copying is made in the unit of the set quantity, however there is an 3sec interval between
the set quantities.
