The workaholic for heavy jobs

This professional flat bed printer (Seikosha FB-840) is flexible, which can cope with even the heaviest workloads. See for yourself how well it adjusts to the demands you can make on it. Regardless of whether it is dealing with simple correspondence or tough jobs in industry, this "jack of all trades" can turn its hand to just about everything.

Multipart sets and types of paper

  • Adjusts automatically to the thickness of the paper
  • Adjustment of the print head
  • Original plus eight copies
  • Suitable for cardboard or similar inflexible materials
  • Up to 840 characters per second for fast jobs
  • 158 characters per second for top print quality
  • 10 resident fonts
  • Integrated zoom function of 66-1600%, which does away with time-consuming and inferior-quality copying.
The Seikosha FB-840 enlarges or reduces automatically.

Flexible paper path

  • Adjustable paper feed: three paths for continuous paper using both tractors (the second tractor is available as an option)
  • Three paths for manual insertion
  • Two paths if using optional, automatic single-sheet insertion
  • The automatic friction change provides a convenient method of switching to a different paper path
  • Output at the rear, at the top or at the front of the printer
The advantage is that Seikosha FB-840 always offers the most comfortable and convenient type of access for every workplace.

Bar codes

The Seikosha FB-840 provides you with 10 of the most commonly used bar code fonts: Inustrial 2 of 5, Interleaved 2 of 5, Codabar, Code 11, Code 128, Code 3 of 9, EAN-8, EAN-13, UPC-E, and Postnet. For applications which require rapid and reliable ba-code reading in connection with printed forms there is a special version available incorporating an integrated bar-code reader.

Skew sensor

This special function makes misaligned documents on manual input a thing of the past. The intelligent sensor function ensures that sheets of paper or forms are simply returned blank if handled incorrectly. This eliminates expensive wasted paper.

Paper jam sensor

You can forget the problem of paper jams as the sensor immediately signals any complications by a message on the display and automatically breaks off the printing job. This provides greater security when the printer is used over a continuous period of time, so you can be sure that the printer is not merely working to fill the waste-paper basket.

Numerous interfacing possibilities

A bi-directional parallel interface and a serial interface are part of the standard features of the Seikosha FB-840. These can be switched automatically by the printer. Information on further interfaces (Coax, Twinax, Ethernet etc.) is available on request.

Greater ease of operation

The clear layout of the operation panel together with a 16-character LCD display ensures rapid and easy access to all functions. Five languages are available on option (D, UK, F, E, I). In addition to this, the most important set-up parameters for various applications can be stored in six print menus. They can also be set and called using software commands.
