TD cartridge replacement required indicator
The TD cartridge replacement required indicator will light up
when toner is needed. If copying is continued while the indicator
is lit, copies will gradually become lighter until the copier stops
and the indicator begins blinking. Replace the old TD cartridge
by following the procedure given below.
After the copier stops, it may be possible to make a few more
copies by taking the TD cartridge out of the copier, shaking it
horizontally, then reinstalling it. If copying is not possible after
this operation, replace the TD cartridge. During long copy run of
a dark original, the START key indicator may blink, the indicator
light up, and the copier stop, even though toner is left. The
copier will feed toner for up to 2 minutes and then the START
key indicator will light up. Press the START key to restart copying.
For best copying results, be sure to use only SHARP Genuine
Supplies which are designed, engineered and tested to maximize the life and performance of SHARP copiers. Look for the
Genuine Supplies label on the toner package.
Drum replacement required indicator
The useful life of the drum cartridge is approximately 30,000
copies. When the internal counter reaches approximately 29,000
copies, the drum replacement required indicator will light up in-

[5] UNPACKING AND
INSTALLATION
1. Unpaking procedure
Be sure to hold the handles on both sides of the copier by two
persons to unpack the copier and carry it to the installation location.
2. Installing procedure
1) Remove all pieces of tape. Then open the original cover and
remove the protective material.
2) Use a coin (or suitable object) to remove the screw.
• Store the screw in the paper tray because it will be used if the
copier has to be moved. (Refer to the description in the following.)
5) Gently pull the TD cartridge out while holding the handle.
6) Hold the strap on the cartridge and remove the TD cartridge upward.

7) Remove the new TD cartridge from the bag. Hold the cartridge on
both sides and shake it horizontally four or five times.
4 or 5 times
8) Hold the tab of the protective cover and pull the tab towards you
to remove the cover.
3) Ensure that the bypass tray is open. Raise the side coverrelease
handle and pull out the side cover until it stops.
4) Push gently on both sides of the front cover to open the cover.
9) Gently insert the TD cartridge along the guides until it locks in
place.
• If dirt or dust is adhered to the TD cartridge, remove it before
installing the cartridge.
10) Close the front cover by holding both sides with your hands and
then close the side cover. The TD cartridge replacement required indicator will go out and the START key indicator will light
up.
• When closing the covers, be sure to close the front cover
securely and then close the side cover. If the covers are
closed in the wrong order, the covers may be damaged.

until it stops.
12) Remove the pressure plate lock. Rotate the pressure plate lock
in the direction of the arrow to remove it while pressing down the
pressure plate of the paper tray.
13) Store the pressure plate lock which has been removed in step 5
and the screw which has been removed in step 2 in the front of
the paper tray.
• To store the pressure plate lock, rotate the lock to fix it on the
relevant location.

14) Push the pressure plate down until it locks in place.
15) Squeeze the lock lever of the front guide and slide the front
guide to match the width of the paper.
16) Move the left guide to the appropriate slot as marked on the
tray.
• When using 11" × 17" copy paper, store the left guide in the
slot at the left front of the paper tray.
17) Load copy paper into the tray.
• Set the paper along the guides.
• The tray holds up to 250 sheets of about 9kg bond paper.
Do not load paper above the maximum height line.
Screw
18) Push the paper tray firmly back into the copier.
19) Ensure that the power switch of the copier is in the OFF position.
Insert the supplied power cord into the power cord socket at the
rear of the copier.
• If you use the copier in a country other than the country
where the copier was purchased, you will need to make sure
that your local power supply is compatible with your model. If
you plug the copier into an incompatible power supply, irreparable damage to the copier will result.
20) Plug the other end of the power cord into the nearest outlet.
• Only insert the power cord into a properly grounded wall
socket.
Do not use extension cords or power strips.

G. Fusing: Fusing section
• Heat and a pressure are applied to the toner image on the copy
paper to fuse the image on the paper.
2. Scanner section
A. Scan process
The scanner has sensors that are arranged in a line. These sensors
scan a certain area of a document at a time and deliver outputs
sequentially. When the line is finished, the next line is scanned, and
this procedure is repeated. The figure below shows the case where
an image which is scanned is shown with solid lines.
The direction of this line is called main scanning direction, and the
scanning direction sub scanning direction. In the figure above, one
line is divided into 5 sections. Actually, however, one line is divided
into thousands of sections. For scanning, the light receiving element
called CCD is used.

Outline of copy operation
A. Setting conditions: Operation panel
• Set copy conditions such as the copy quantity and the copy den-
sity with the operation section, and press the START key. The
information on copy conditions is sent to the MCU.
B. Image scanning: Scanner section
• When the START key is pressed, the scanner section starts scan-
ning of images.The light from the copy lamp is reflected by the
document and passed through the lens to the CCD.
C. Photo signal/Electric signal conversion:
Scanner section
• The image is converted into electrical signals by the CCD circuit
and passed to the MCU.
D. Image process: MCU
• The document image signal sent from the CCD circuit is processed
under the revised conditions and sent to the LSU (laser unit) as
print data.
E. Electric signal/Photo signal (laser beam)
conversion: LSU
• The LSU emits laser beams according to the print data. (Electrical
signals are converted into photo signals.)
• The laser beams are radiated through the polygon mirror and
various lenses to the OPC drum.
F. Printing: Process section
• Electrostatic latent images are formed on the OPC drum according
to the laser beams, and the latent images are developed to be
visible images (toner images).
• Meanwhile the paper is fed to the image transfer section in
synchronization with the image lead edge.
• The toner image is transferred on the paper.

The basic resolution indicates the scanner capacity. The basic resolution is expressed in dpi (dot/inch) which shows the number of light
emitting elements per inch on the document.
The basic resolution of this machine is 400dpi.
In the sub scanning direction, at the same time, the motor that drives
the optical system is controlled to scan the image at the basic resolution.
