IBM Ricoh FB750 manual Epp

EPP

Enhanced Parallel Port mode. On some computers, you will have an EPP emulation, which is denoted by a version number in the BIOS (ie. EPP 1.7). This mode will allow the computer to send an advanced parallel port signal to installed parallel port device(s). The EPP mode also allows fast communications through the parallel port and is the preferred mode for most parallel port devices.

Error Diffusion

A single-bit scanning mode that uses the size of pixels to mimic grayscale imaging with good detail.

FAQ or Frequently Asked Questions

This is a listing of questions that are often asked of tech support and their answers. If you are having problems, if you look at the FAQs first, you might be able to solve your own problem without needing to contact Tech Support. You can find Info’s FAQs on the Web site, the BBS, and through the fax-back system.

Fax or Facsimile

This is a method to send digitized information from a computer to another computer or Fax device through the phone lines. Faxing requires the sending computer to have a fax-modem and faxing software installed and the receiver to have either a computer with a fax-modem and fax software or a dedicated fax machine.

File Formats

Some programs allow you to save images or OCR text as a variety of file formats. Which formats are available depend on the program you are using. Some file formats are specific to individual programs and can only be used in that program. In which file format you save an image or OCR text file depend entirely upon your uses for the file.

Free Disk Space

This is the amount of space you have FREE on your hard drive, not to the total hard drive space. If you have a lot of programs and files on your hard drive, you may not have much free disk space.

Gamma

The gamma curve relates to the RGB component values of pixels in an image. Set the gamma curve to match the eye (2.2).

Graphics Formats

There are several graphics formats in which you can save a scanned image. The major differences between graphics formats is the way the image is stored (compressed vs. uncompressed), displayed (how you or someone else can view the image), or commonly used (some formats were designed with specific uses in mind). The appearance of any graphic differs from computer to computer based on the hardware and software used to view it.

Grayscale

An image made up of shades of gray, like a black and white photo. Generally, grayscale is either 4-bit, allowing 16 shades, or 8-bit, allowing 256 shades and providing a more photo-realistic quality.

Halftone

Halftone images are composed of a pattern of black dots that simulate grayscale, such as many newspaper photos.

HiColor or RealColor

HiColor designates a 15-bit or 16-bit (bits per pixel) graphics mode, 32,768 or 65,536 colors.
