HOW TO 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 bottle?

1

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

*5 : F34/F35/F36 latch

In the event of a fixing-related error, the setting changes to "1" so that power OFF/ON will not clear the error condition. After correcting (repairing) the problem, reset this to "0" to re-enable copying.

*6 : Return to EKC screen after copying reservation

If EKC setup is enabled, then if this bit is set to "1" (return to screen) the copier will immediately display the EKC password-request screen following exit of the final sheet for the reserved jobs. If copying is not reserved, the copier will wait 1 minute following job completion before displaying the EKC passwordrequest screen.

*7 : By-pass feed nonstandard size selection

This setting determines whether the system detects the size of the paper in the by-pass tray. If the setting is "1" (handle as nonstandard size), the size is not detected and copying is based on the maximum paper size.

*8 : Non-display of advance/delete buttons for job list

Under default conditions, the job list screen allows for deletion or priority changing of jobs that have been stored in E-RDH memory.

If this bit is set to "1"(non-display), however, the advance and delete buttons will not appear on the display so that it will not be possible to delete or reorder the reserved jobs.

*31 : MPC correction control

1 ADJUSTMENT

2 ISW

3 SERVICE

These switches determine whether MPC correction is carried out when sub power turns on.

MPC (maximum laser power correction) is designed to optimize copy density (mainly to prevent excess density), and is generally carried out every 20 copies.

In the copier is left off for a protracted period of time, toner may begin to lose its charge, resulting in excess density when copying restarts. To prevent this problem, the default setting causes the copier to automatically execute MPC when power turns ON (from OFF mode or from main power OFF) if the following two conditions hold: (1) the copier has been off for a prolonged period (at least 8 hours), and (2) the ambient humidity is 60% or higher.

If you set the switches to "1", "0", then the copier will execute MPC at power ON if either of the above two conditions hold. If the switches are set to "0", "1", then MPC will always be carried out at power ON.

*34 : SW2 (sub switch) turns ON with SW1 (main switch)

Setting this bit to "1" will increase the warm-up time.

Reason:

The CB (overall control board) houses both an engine-control CPU and a system-control CPU. Switching ON of the main power does not start the engine CPU, but does start the power supply to the system CPU. The system CPU is initialized, and then the OS is initialized, and then memory and other hardware checks are performed. This initialization sequence takes about 6 seconds (until the fax, printer/scanner, and copy LEDs have gone ON/OFF). When this setting is "0", the engine does not start if SW2 is pressed during initialization.

When the printer option is installed, the setting becomes “1”, and cannot be changed.

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 dection.

4. Running mode 4 (Paperless/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 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.
