Apple OneScanner Dispatcher is the scanning program Apple supplied with the Apple Color OneScanner 600/27 and the Apple Color OneScanner 1200/30. It scans, edits and archives images and documents, and passes them by drag and drop to a printer, a fax program, the Xerox TextBridge OCR program or other applications. A plug-in module lets Adobe Photoshop and compatible programs scan directly.[1][2] Apple's Tech Info Library mentions versions 1.0 and 1.0.2. The 1200/30 came with Dispatcher 2.0, which Apple described as having several enhancements over the original.[3][4] Dispatcher does not support the original Apple Color OneScanner.[5]
Features
[edit | edit source]The Dispatcher window has four buttons (Scan, Scan Router, Image Edit and Archive) and a row of drag-and-drop icons for Print, Fax, TextBridge and up to three more applications of the user's choice.[2] The image editor has the usual tool palette: selection rectangle, grabber, paint bucket, eraser, spray can, clone, lasso, zoom, text, pencil, paintbrush and smudge. It opens JPEG, TIFF, PICT, Photoshop 2.5 and EPS files and can use Photoshop-compatible filters such as Kai's Power Tools.[1] Three automatic functions work from the prescan: Suggest a Crop, Adjust Tone and Straighten.[1]
Requirements
[edit | edit source]Dispatcher needs at least 3 MB of free RAM, and TextBridge needs 4 MB; running both needs 7 MB free on top of the system's own use.[2] It needs a display of at least 640 × 480. On a Macintosh 12-inch RGB display, at 512 × 384, the controls fall off the screen and the program cannot be used.[6]
Known problems
[edit | edit source]| Problem | Cause or fix |
|---|---|
| Dispatcher window does not appear at launch (version 2.0) | Version 2.0 remembers whether the window was closed. Choose Dispatcher from the Window menu or press Command-0 (zero).[7] |
| Straighten does nothing | The feature needs a document with clear, high-contrast rectangular edges, some image content, and space from the edges of the scan window. Use Rotate, Arbitrary in the image editor instead.[8] |
| Automatic Straighten rotates the image 30-45 degrees or scales it wrongly (1.0, 1.0.2) | Do not place the original against the alignment mark and rulers, or do not use Automatic Straighten.[3] |
| Suggest Crop turns itself on with Straighten Automatically | Normal behaviour; draw a selection marquee before scanning.[9] |
| White line about five pixels tall along the bottom of scans | Caused by the Dispatcher software; remove it in an image editor.[10] |
| Memory missing after quitting, so Photoshop will not open | A ColorSync 2.0.1 code fragment is not unloaded and splits free memory. Restart the Macintosh, and quit Dispatcher before running memory-hungry programs.[11] |
| Scanned image far too big on screen | A 300 dpi scan is shown pixel for pixel at about four times print size. Prescan and select only the area needed, change the display resolution before launching, or zoom out.[12] |
| Cannot choose 12 dpi | 12 dpi is the scanner's hardware limit; Dispatcher's lowest setting is 60 dpi, and previews are 75 dpi.[13] |
| TextBridge's scan option is dimmed | If Dispatcher scans normally, delete the Scanner Settings file in the System Folder and the TextBridge Preferences file in the Preferences folder so they are rebuilt.[14] |
Scanner hardware faults, such as "Unable to initialize the scanner driver", are covered in the Apple Color OneScanner 600/27 Troubleshooting Guide.
