3. OPERATION SECTION
*1:
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 cop-
ies by taking the TD cartridge out of the copier, shaking it horizon-
tally, 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.
In case of low coverage, the developer life lamp lights up at 14,500
sheets, and flashes at 15,000 sheets and the machine stops.
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 replace-
ment required indicator will light up indicating that replacement of
the drum cartridge will be needed soon. When the indicator begins
to blink, replace the drum cartridge by following the procedure
given below.

AL-1611/AL-1622 OPERATIONAL DESCRIPTIONS
6 – 1
[ 6 ] OPERATIONAL DESCRIPTIONS
1. OUTLINE OF OPERATION
The outline of operation is described referring to the basic configuration.
(Basic configuration)
Outline of copy operation
A. Setting conditions: Operation panel
• Set copy conditions such as the copy quantity and the copy density
with the operation section, and press the START key. The informa-
tion on copy conditions is sent to the MCU.
B. Image scanning: Scanner section
• When the START key is pressed, the scanner section starts scanning
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 synchroni-
zation with the image lead edge.
• The toner image is transferred on the paper.
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 sequen-
tially. When the line is finished, the next line is scanned, and this proce-
dure 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 scan-
ning direction sub scanning direction. In the figure above, one line is
divided into 5 sections. Actually, however, one line is divided into thou-
sands of sections. For scanning, the light receiving element called CCD
is used.
The basic resolution indicates the scanner capacity. The basic resolu-
tion is expressed in dpi (dot/inch) which shows the number of light emit-
ting 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 resolu-
tion.
