[6] OPERATIONAL DESCRIPTIONS

1. Outline of operation

The outline of operation is described referring to the basic configura- tion.

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 resolu- tion 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 resolu- tion.

AR-160, AR-161 specifications

The Sharp AR-161 and AR-160 are monochrome multifunction printers that have made a mark in the office equipment landscape with their impressive features, technologies, and characteristics. Both devices are designed to cater to the needs of small to medium-sized businesses that require reliable, efficient, and compact systems for their printing, copying, and scanning needs.

One of the main features of the Sharp AR-161 and AR-160 is their impressive speed. The AR-161 can produce up to 16 pages per minute (ppm), while the AR-160 offers a slightly lower output at 15 ppm. This makes both models suitable for environments where quick document turnaround is essential. Additionally, both machines have a warm-up time of approximately 20 seconds, ensuring minimal downtime when starting up.

In terms of paper handling, both models come equipped with a 250-sheet paper drawer and a 100-sheet bypass tray, allowing for a variety of media types and sizes. The automatic document feeder (ADF) can accommodate up to 50 sheets, making it easier to handle multi-page documents without manual intervention. This feature enhances workflow efficiency significantly, particularly in busy office settings.

The Sharp AR-161 and AR-160 utilize advanced copying technologies, including a high-resolution scanning capability of up to 600 x 600 dpi. This means that documents are reproduced with clarity and detail, making them suitable for professional presentations and reports. The devices also offer various copying options, such as zoom, collation, and reduction/enlargement, providing versatility for different copying tasks.

Both models are equipped with Sharp's innovative ImageSEND technology, which allows users to scan documents directly to email, network folders, or USB drives with ease. This feature enhances productivity by streamlining the scanning process, ensuring that documents can be shared quickly and efficiently.

Furthermore, energy efficiency is a hallmark of the Sharp AR-161 and AR-160, as both models are ENERGY STAR qualified. This means they are designed to use less energy, helping businesses reduce their environmental impact while also saving on operational costs.

In conclusion, the Sharp AR-161 and AR-160 combine speed, versatility, and energy efficiency in a sleek design. Their advanced copying technologies and smart features make them ideal choices for businesses seeking reliable multifunction devices that can enhance productivity without compromising on quality.
