IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the copier power cord is unplugged.

2. The wall outlet should be near the copier and easily accessible.

3. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main power switch is turned off.

4. If any adjustment or operation check has to be made with exterior covers off
or open while the main switch is turned on, keep hands away from electrified
or mechanically driven components.

5. If the Start key is pressed before the copier completes the warm-up period
(the Start key starts blinking red and green alternatively), keep hands away
from the mechanical and the electrical components as the copier starts
making copies as soon as the warm-up period is completed.

6. The inside and the metal parts of the fusing unit become extremely hot while
the copier is operating. Be careful to avoid touching those components with
your bare hands.

HEALTH SAFETY CONDITIONS

1. Never operate the copier without the ozone filters installed.

2. Always replace the ozone filters with the specified ones at the specified
intervals.

3. Toner and developer are non-toxic, but if you get either of them in your eyes
by accident, it may cause temporary eye discomfort. Try to remove with eye
drops or flush with water as first aid. If unsuccessful, get medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course on
those models.

2. The NVRAM on the system control board has a lithium battery which can
explode if replaced incorrectly. Replace the NVRAM only with an identical
one. The manufacturer recommends replacing the entire NVRAM. Do not
recharge or burn this battery. Used NVRAM must be handled in accordance
with local regulations.

SAFETY AND ECOLOGICAL

1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly
when exposed to an open flame.

2. Dispose of used toner, developer, and organic photoconductors in
accordance with local regulations. (These are non-toxic supplies.)

3. Dispose of replaced parts in accordance with local regulations.

4. When keeping used lithium batteries in or der to dispos e of them later, do not
put more than 100 batteries per sealed box. Storing larger numbers or not
sealing them apart may lead to chemical reactions and heat build-up.

NOTES

FOR DISPOSAL

LASER SAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair of
laser-based optical units in the field. The optical housing unit can only be repaired
in a factory or at a location with the requisite equipment. The laser subsystem is
replaceable in the field by a qualified Customer Engineer. The laser chassis is not
repairable in the field. Customer engineers are therefore directed to return all
chassis and laser subsystems to the factory or service depot when replacement of
the optical subsystem is required.

WARNING

I

Use of controls, or adjustment, or performance of procedures other than
those specified in this manual may result in hazardous radiation exposure.

WARNING

I

WARNING: Turn off the main switch before attempting any of the

procedures in the Laser Unit section. Laser beams can
seriously damage your eyes.

For Adonis-C1

The mechanical components of the scanner unit are the same as for the NAD.
However, the following items have been changed because this machine scans at
600 dpi.

·

The lens is larger

·

Because the lens size has been changed, the drive layout has been changed as

shown in the above illustration (note the position of the scanner drive motor).

·

Image processing is slightly different

·

To reduce the electrical noise generated by the high frequency image data

signal, a shield plate has been added to the lens block unit.

The CCD has two output lines, one each for odd and even pixels, to the analog

converter. The digital signals go to the driver, where they are converted to serial

IMAGE PROCESSING 14 January, 2000

Filtering

There are two software filters: MTF and smoothing, as in the NAD. There are four
MTF filter types: filter strength for main scan direction, filter strength for sub scan
direction, filter coefficient for main scan direction, and filter coefficient for sub scan
direction. These filters can be adjusted with SP mode.

When the filter is stronger in the main scan direction, lines parallel to the feed
direction are emphasized. When the filter is stronger in the sub scan direction, lines
at right angles to the feed direction are emphasized.

The relationship between the filter coefficient and the filter strength is as follows.
MTF filter coefficient

(Weak) (Strong)
0 ® 1 ® 2 ® 3 ® 4 ® 5 ® 6 ® 7 ® 8 ® 9 ® 10 ® 11 ® 12 ® 13 ® 14 ® 15

MTF filter strength

Smoothing filter coefficient

(Weak) 0 ® 1 ® 2 ® 3 ® 4 ® 5 ® 6 ® 7 (Strong)

It is difficult to explain how to use the filter coefficient and filter strengths to control
MTF and smoothing. Refer to the following charts to determine how to make the
filters weaker or stronger. The values in the bold columns are the default settings.

SP4-903-48 is only effective if MTF is
enabled with SP4-904-3.
See “Detailed Descriptions - Image
Processing” for details.

Selects the MTF filter strength in the

Checks for bad sectors on the hard
disk that develop during machine use.
Press “1” to start. This takes 4 minutes.

This SP mode should be done when an
abnormal image is printed. There is no
need to do this at installation as the
hard disk firmware already contains
bad sector information, and damage is
not likely during transportation.
Bad sectors detected with this SP
mode will be stored in the NVRAM with
the bad sector data copied across from
the firmware.
If the machine detects over 50 bad
sectors, SC361 will be generated. At
this time, use SP4-911-2.

Formats the hard disk. This takes 4
minutes. Press “1” to start.

Do not turn off the main power
switch during this process.

Decides the disk drive motor (spindle motor) stop timing.

0: Enabled

The hard disk stops in low power mode. The first copy
after returning to standby will take longer.

1: Disabled

The hard disk keeps going in low power mode.

Resets the bad sector information
which is stored in the NVRAM. Press
“1” to start.

This SP should be performed when the
hard disk is replaced.
