A scanner from [[Dart Electronics]] for use with Amstrad's [[DMP2000]] and [[DMP3000]] printers.

== Reviews ==

The Dart Scanner was reviewed in [[Amstradbladet 1987, Issue 3]], pages [[:File:Amstrad Bladet8703008.jpg|8]], [[:File:Amstrad Bladet8703009.jpg|9]], [[:File:Amstrad Bladet8703010.jpg|10]] (Danish)

== Technical ==

The scanner optics are attached to the printer head. The scanner interface connects to the expansion port.

Uses port FBEFh, the port seems to be read-only.
  Bit2 Carriage Returned/Parked (0=Wait/Head Parked, 1=Scan/Head Moving)
  Bit? Scanned Pixel Color      (0=Black, 1=White)
Scanning is done in single scanlines (one pixels height). The scanning procedure waits while FBEFh.Bit2=0 (which probably indicates that the head is in the left-most position, or that it has just leaved it, or so). The horizontal "dot clock" is implemented as software delays. When scanning a black dot, one or more bits in Port FBEFh become non-zero (not sure which bit; the driver software simply checks "IF Port[FBEFh]<>FFh THEN PLOT pixel").

Caution: The scanning software may be required to be adjusted for different printer/scanner versions (eg. an extra delay for DMP3000), and, the printer DIP switches must be set up properly (see last page of manual for details).

The manual doesn't mention anything about compatibility with DMP2160/DMP3160/DMP3250di - theoretically it should be possible to attach the Scanner to them (since they have the same case as DMP2000/DMP3000). One problem is that the newer printer models do move the head at faster speed (160 CPS instead of 105 CPS), so the horizontal resolution (and position) will change; which could be fixed at software side. Apparently this was handled in later versions, an advert in [[ACU]] Nov 1988, page 21 states that the package does also work with DMP2160/DMP3160.

Observe that the manual includes some '''patches''' for using the scanning software with different printers, ie. it may be required to do some small modifications before using the above drivers. And, the manual says that '''DIP switches''' on the printer must be configured properly.
