1. Installation Precautions
WARNING
• Do not use a power supply with a voltage other than that specified. Avoid multiple connections to
one outlet: they may cause fire or electric shock. When using an extension cable, always check
that it is adequate for the rated current. ............................................................................................
• Connect the ground wire to a suitable grounding point. Not grounding the copier may cause fire or
electric shock. Connecting the earth wire to an object not approved for the purpose may cause
explosion or electric shock. Never connect the ground cable to any of the following: gas pipes,
lightning rods, ground cables for telephone lines and water pipes or faucets not approved by the
• Do not place the copier on an infirm or angled surface: the copier may tip over, causing injury. .....
• Do not install the copier in a humid or dusty place. This may cause fire or electric shock. ..............
• Do not install the copier near a radiator, heater, other heat source or near flammable material.
This may cause fire. ..........................................................................................................................
• Allow sufficient space around the copier to allow the ventilation grills to keep the machine as cool
as possible. Insufficient ventilation may cause heat buildup and poor copying performance. ..........
• Always handle the machine by the correct locations when moving it. ..............................................
• Always use anti-toppling and locking devices on copiers so equipped. Failure to do this may
cause the copier to move unexpectedly or topple, leading to injury..................................................
• Avoid inhaling toner or developer excessively. Protect the eyes. If toner or developer is
accidentally ingested, drink a lot of water to dilute it in the stomach and obtain medical attention
immediately. If it gets into the eyes, rinse immediately with copious amounts of water and obtain
medical attention. ..............................................................................................................................
• Advice customers that they must always follow the safety warnings and precautions in the copier’s

Turns on or off the DF scanning position adjust mode, in which the DF original scanning position is adjusted
automatically by determining the presence or absence of dust on the slit glass. Also changes the reference
data for identifying dust.
Reference
In the DF original scanning position adjust mode, the presence or absence of dust is determined by comparing
the scan data of the original trailing edge and that taken after the original is conveyed past the DF original
scanning position. If dust is identified, the DF original scanning position is adjusted for the following originals.

U091Checking shading
Description
Performs scanning under the same conditions as before and after shading is performed, displaying the original
scanning values at nine points of the contact glass.
Purpose
To check the change in original scanning values before and after shading. The results may be used to decide
the causes for fixing unevenness (uneven density) of the gray area of an image: either due to optical (shading
or CCD) or other problems.
Also to check the causes for a white or black line appearing longitudinally.
Method
1. Press the start key. The screen for selecting an item is displayed.
2. Select the item to be operated. The selected item is displayed in reverse.
DisplayDescription
SHD BEFOREPerforms scanning before shading and displays the result.
SHD AFTERPerforms scanning after shading and displays the result.
3. Press the start key. Scanning is performed under the selected conditions and the result is displayed.
When scanning is performed before shading, the scan value at the machine center should be slightly
different from those at the machine front and rear. When scanning is performed after shading, there should
be no difference between respective values. Any differences between the values at machine front and rear
indicates that scanner problem causes the fixing unevenness.
If the displayed results indicate no shading problems, the fixing unevenness (uneven copy density) is
caused by factors other than in the scanner section (shading or CCD).
If a black line appears, the cause may assumed to be based on the results of the scanning operation before
shading: if a white line appears, they may be assumed based on the results of the scanning operation after
shading. Note that depending on the thickness and location of the black or white line, it may not be possible
to use this method to determine the cause. This is because the displayed values obtained from scanning at
the limit of nine points are insufficient to provide significant information.
