B. Outline of print process

The printer section of this machine employs the laser print system where print images are formed by the laser beams on the OPC drum.

A high voltage (corona) is applied from the main charger to the OPC drum to charge the OPC drum.

Laser beams are radiated to the charged OPC drum to form electrical images on the OPC drum. (Exposure)

(At that time, the print image on the OPC drum cannot be seen: latent electrostatic image)

By the potential difference between the unexposed area and the latent electrostatic images, toner ia attracted only to the im- ages.(Developing)

(At that time, the print image formed by toner on the OPC drum can be seen. Visible images)

The toner image on the OPC drum is transferred on the print paper by the transfer corona (voltage).

After that, the print paper with the toner image on it is subject to heat and pressure in the fusing section to fuse the image on the paper.

This machine employs the following organic photoconductor (OPC) drum.

An OPC drum is used for the photoconductor.

C. Actual print process

(1) Charging

A high voltage is applied to the main charger, and negative charges are discharged to the OPC drum. A screen grid is provided between the main charger and the OPC drum, and negative charges are uniformly charged on the OPC drum surface.

Positive charges are attracted by the negative electrode on the OPC drum surface and excited in the aluminum layer in the OPC drum.

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.
