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 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

If this bit is set to "1", then if the user specifies more than 25 stapled sets the copier automatically stops after reaching the 25th set, and displays a message instructing the user to remove the paper and press the START button.

When the TLD (toner level detector) detects that the toner-out condition has persisted for a fixed length of time, the copier waits an additional number of copies (as specified by DIPSW4 – 0, 4 – 1) and then displays a message instructing the user to load new toner.

If 1-shot display is enabled: If the copy limit is exceed during staple-mode operation, a message indicating this appears on the display, and copying continues in sort mode.

Note that this setting is related to the “1-SHOT DISPLAY TIME” setting available under key-operator mode. For information about memory switches, refer to the Instruction Manual.

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.

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.

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), the size is not detected and copying is based on the maximum paper size.

*12 : Copy-sheet size priority in image area

This setting determines how the copier handles platen copying when the original size differs from the copy-sheet size when the AMS setting is cleared. If this bit is set to "1" (whole-page image in platen mode only), then the copier will not erase the area outside of the original (so that area outside of the APSdetected size is also copied).

If this bit is set to "0", then the copier does erase the area outside of the original.

Note that in RADF copying, the copier will always erase the area outside of the original regardless of this setting.

Related settings are DIPSW8 – 0 (Selection of automatic erasure outside original), key-operatormode and memory switch 4. For information about memory switches, refer to the Instruction Manual.

8.5x11 APS (Japan, Europe), A4 APS (U.S.A.)

If this bit is to "1" (No), the copier will forcibly copy as A4 in Japan/Europe if it detects an original size of

8.5x11, and will forcibly copy as 8.5x11 in U.S.A. if it detects an original size of A4). Under the default setting, APS operates for both A4 and 8.5x11.

*15 : Settings related to nonstandard original sizes

• DIPSW21 – 5 "Notify of small size of platen mode" This setting determines how the copier operates if

it detects that size of the original is smaller than A4 (Japan/Europe) or 8.5x11 (U.S.A.). If this bit is set to "0", then according to the setting of DIPSW21 – 3 "Notify of nonstandard small size of platen mode" the copier will either execute copy as nonstandard size or will notify of the APS detected size. If this bit is set to "1", then all originals are reported as size A4/8.5x11.

• DIPSW21 – 3 "Notify of nonstandard small size of platen mode"

This setting is effective only if DIPSW21 – 5 is set to '0'. If this bit is set to "1", the copier will notify that size is nonstandard if an original smaller than A4 (Japan/Europe) or 8.5x11 (U.S.A.) is set on the original glass.

• DIPSW7 – 4 "Nonstandard-size notification for platen APS B6 (Japan) / A5 (Europe) / 5.5x8.5 (U.S.A.)"

This setting is effective only if DIPSW21 – 5, DIPSW21 – 3, and DIPSW7 – 3 are all set to "0".

This setting determines how the copier notice the original size when the platen APS detects that the size is B6 (Japan), A5 (Europe), or 5.5x8.5 (U.S.A.). If this bit is set to "1", the copier notice the minimum size.

If the bit is set to "0", the copier reports that the size is nonstandard.

• DIPSW7 – 3 "Nonstandard-size notification for platen APS A4 (Japan, Europe) / 8.5x11 (U.S.A.)"

This setting is effective only if DIPSW21 – 5, DIPSW21 – 3, and DIPSW7 – 4 are all set to "0".

Accurate detection of the outer boundary of the original may become difficult if the original is light in density or if extraneous light (sunlight, room fluorescent light, etc.) has penetrated the copier. Setting the threshold to lower values facilitates detection for light-density originals but increases the risk of incorrect detection due to extraneous light.

*30 : MPC correction control

1 ADJUSTMENT

2 ISW

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

MPC (laser maximum 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 "01", then the copier will execute MPC at power ON if either of the above two conditions hold. If the switches are set to "10", then MPC will always be carried out at power ON.

If "1", "1" is set to DIPSW16 – 6 and DIPSW16 – 7, then MPC will never be carried out at power ON.

*33 : 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). Normaly, pressing the SW2 during this time will not cause the engine to start.
