ADJUSTMENT

HOW T O USE THE ADJUSTMENT SECTION

[1] Construction

This section details adjusting items and procedures. Use this
section for making adjustments and as a checklist before
implementing corrective measures in the field.

1. Does the power supply meet the requirements?

2. Is the power supply properly grounded?

3. Is the machine sharing its power source with another high
current consumption machine that draws large currents
intermittently? (e.g. an elevator, air conditioner, or other
source of electrical consumption)

4. Is the installation environment suitable?
a. The machine must be installed in a well-ventilated

place free from high temperature, high humidity and
direct sunlight.

b. The machine must be installed on a level floor.

5. Does the cause of a defective image lie in the original
itself?

6. Is the density adjusting control at the proper position?

7. Are the original glass and RADF platen guide clean?

8. Is the correct paper being used for the copy?

9. Are the copying materials and parts replaced when they
reach the end of their usable life? (developer, drum,
cleaning blade, etc.)

10. Is there toner in the toner cartridge?

The following items should also be observed when repairing
the machine.

1. Only one side of the AC power line is disconnected when
the main power of this machine is turned off. Always
unplug the machine before beginning work. If absolutely
necessary to work with the power on, exercise care to
avoid being caught in the scanning rear of the exposure
unit.

2. Special care should be taken when handling the fixing unit
since it operates at extremely high temperatures.

3. The developing unit is surrounded by a strong magnetic
field. Keep watches and metering equipment away from
it.

4. Avoid scarring the drum with tools or similar objects.

5. Do not touch IC pins with your bare hands.

ADJUSTMENTS WHEN REPLACING PARTS

Adjustments (including checks) and settings are not only
required when a defective copy image occurs, but also after
replacing or reinstalling certain parts.

[How to Use the Tables]

The following items are used in the tables throughout this
section.

1. Mode

Indicates the adjustment mode.
[“25”] : 25 mode
[“36”] : 36 mode
[“47”] : 47 mode

2. Codes

Indicates the applicable code and/or Copy Quantity Setting
button for each mode.

3. Conditions

New: Indicates adjustment (including check) is required when

replacing a new part.

Reset: Indicates adjustment (including check) is required when

a part has been re-installed.

4. Symbols used in the tables

1 2 : .................. Indicates there is a priority sequence for

adjustments (including checks) and set­tings.

(Empty circle): Indicates adjustments (including checks)

and settings that can be carried out inde­pendently.

Running mode 1 is an intermittent copy mode. In this
mode, after the set number of copy operations has been
completed, the machine goes into the copy ready status,
waits 0.5 sec, then starts the same operation again.

2. Running mode 2 (Paperless intermittent copy mode)
Running mode 2 is a paperless intermittent copy mode. It
makes copies at roughly the same timing as for a normal
copy, without performing paper detection or jam detec­tion. Also, like running mode 1, after the set number of
copy operations has been completed, the machine goes
into the copy ready status, waits 0.5 sec, then starts the
same operation again.

3. Running mode 3 (paperless mode)
Running mode 3 is a paperless mode. It makes copies at
roughly the same timing as for a normal copy, without
performing paper detection or jam detection.

4. Running mode 4 (Paper less endless mode)
Running mode 4 is a paperless endless mode. It auto­matically sets the copy quantity to infinity. Also, like
running mode 3, it makes copies at roughly the same
timing as for a normal copy, without performing paper
detection or jam detection.

5. Running mode 5
Running mode 5 is a process running mode. It consists
of running mode 4 plus an operation consisting of an
optics each-time scan and an automatic paper feed tray
change.

Amount of reflective light from drum

Dmax sensor output can hardly be
detected

Too many discrepancies in data for proof­ing by calculation the relationship of the
value read by the Dmax sensor patch
and the scanner patch density, and the
precision of the calculation is defective.

Patch data numbers read by scanner
is less than what is required in the
above calculation.

Patch level numbers read by scanner
is less than what is required in the
above calculation.

The density of the patch read by the
Dmax sensor is almost the same for the
lowest and highest density and so the
above calculation could not be done.

The data for calculating the PWM
correction curve from the value read
by Dmax sensor patch has too many
discrepancies and the precision of
the calculation is defective.

The Dmax sensor value was below the
standard and so the PWM correction
curve could not be calculated.

The density of the patch read by the
Dmax sensor is almost the same for
the lowest and highest density and so
the PWM correction curve could not
be calculated.

There was no difference between the
lowest and highest density in the Dmax
sensor ouput converted with the proof­ing value and so the PWM correction
curve could not be calculated.

The PWM correction curve prepared by
calculation has a special attribute that
does not allow it to be increased mo­notonously and so could not be used.
