  • Signature

    The signature function is used in conjunction with booklet printing. The spine of a book is made up of numerous smaller booklets which are then bound together. For example, if you fold a sheet of A4 paper in half you can create 4 pages of A5. The signature option limits the amount of pages used to print individual booklets in order to make folding easier.

  • Secure Print

    Secure printing is where a PIN (Personal Identification Number) can be assigned to each print job sent to the printer. The user has to enter the PIN number into the printer's operator panel in order to have the document printed. This feature is useful when a confidential document needs to be printed on a shared network printer. To use this function the printer must have an internal hard disk drive (HDD) installed.

  • Saturation

    Saturation represents how pure a colour is. It is the amount or strength of the colour. Saturation is measured as a percentage from 0% to 100%. If a colour has a saturation of 0% then the colour will contain no hue and would appear grey. On the other hand, if the saturation of a colour is 100% then the colour will appear fully saturated.

  • RGB

    RGB (Red, Green and Blue) refers to a colour system used in video technology equipment such as computer monitors and television screens. These types of imaging technology use Additive Colour Reproduction. For example, each pixel on a computer monitor is made up of these three colours.

    Power save mode is an energy saving feature of printers. In Power Save Mode, the printer will, after a specified length of time, allow the fuser unit to cool, stop the fans (dependent on printer type) and motors and stop any processor activity. In this state the printer consumes less power than when printing or waiting to print. The length of time the printer waits before power save mode is configurable. Oki's printer products comply with Energy Star.

  • Memory

    Oki's printing devices contain various types of electronic memory which provide various functions: RAM - Random Access Memory. The printer uses RAM in a similar way as a PC uses RAM. When the printer receives a print job, the data is stored in RAM while the printer processes it. Certain functions like DUPLEX printing and printing banners are memory intensive applications and therefore require larger amounts of RAM. Many of Oki's printers can have additional RAM added as an option. FLASH - Is a type of non-volatile memory which is used within Oki's printers to store font data, macros, templates and the printers configuration settings. Typically the amount of FLASH within the printer is fixed and cannot be expanded. ROM - Read Only Memory. ROM is used to store the printer's firmware as well as any resident font data. Like FLASH memory, the size of the ROM is fixed and cannot be expanded.

  • Media Check

    Media check is a function that checks that the paper size selected with the print job matches the size of paper in the printers paper tray. If the size does not match, an error message is displayed on the printer's operator panel.

    08/04/2005

  • LED Technology

    Oki's printers are electro photographic printers where a light source shines light on a light sensitive drum creating an attractive charge like a magnet. Toner is then attracted to this charge and then transferred to the paper and finally fused in place. The light sources employed by Oki printers are known as Light Emitting Diodes or LED's for short. Digital LED Technology has a number of advantages such as no moving parts allowing faster printing and higher print quality

    08/04/2005

  • Colour Registration

    The CMYK (cyan, magenta, yellow and black) printing process uses overlapping inks of cyan, magenta, yellow and black. To produce the best possible output, the colours must print in specific positions so that overlaps are accurate. If the colours are not aligned, the resulting print may appear to be blurred, or have white space around text or produce undesired colour.
