Support of the one pass scanner model MICROTEK IISP (ScanMaker) or the OEM model HIGHSCREEN Flatbed Color IIs (SCSI, up to 600dpi). 2. Support of black/white, built-in halftone (dither), one-pass-color-scan, grey, red, green and blue scan. 3. Individual setting of resolution, scanning frame, contrast, shadow, midtone, highlight, exposure time and scanning speed for download to the scanner. 3. Scanning to IFF File of 1, 8 or 24 bit color depth. The maximum size of the scanned image is independent from the RAM size. After the scanning process it is possible to start an external program. 4. GUI for preview and configuration of the driver. You need Kickstart 2.04 or higher. 5. Sizeable preview window in black/white or grey scale. There are much more skilled programs to view and manipulate the scanned images in color. (A tool like ADPRO, IMAGE FX or so is needed, if you want to do sophisticated postproduction) 6. Screenmode requester to define screen for working. 7. Configurable SCSI device and SCSI ID. ( Yes, the driver supports only SCSI connectable Microtek scanners. This is not rather bad, since I do not know of any NON-SCSI scanner from Microtek). 8. Support of Microtek II three pass color scanner, but I have implemented this support without testing because I have no Microtek II scanner. Try it and report to me all problems (if any) to implement a full working version. 8. The driver is tested with the following SCSI drivers: oktagon.device and gvpscsi.device V4.5. 9. ScanTek is written using SAS C 6.55. 10. ScanTek is SHAREWARE. 11. The non registered version of ScanTek is a full working version but all scanned images have black lines to motivate you to register. @ENDNODE @NODE Requirements "System Requirements" @{B}System Requirements@{UB} 1. An AMIGA with Kickstart 2.04 or higher. 2. A SCSI host adapter (commonly known as SCSI controller) with an external connector for the scanner :-) 3. You should have more than 2 MByte RAM in one piece. If you have less, the scanning would be rather boring than fun. 4. A harddisk with lots of free space. @ENDNODE @NODE Installation "Installation" @{B}Installation@{UB} The archive contains the following files: ScanTek/ScanTek - The scanner driver ScanTek/ScanTek.info - The appropriate info file ScanTek/ScanTek.guide - This amigaguide document ScanTek/ScanTek.guide.info ScanTek/ReadMe - A short description ScanTek/ReadMe.info ScanTek/OrderForm - The english orderform ScanTek/OrderForm.info ScanTek/Bestellformular - The german orderform ScanTek/Bestellformular.info ScanTek/Images/ - Directory for scanned images ScanTek/Temp/ - Directory for temporarily files To install, unpack the archive to a preferred location at your hard disk. Assigns are not necessary. @ENDNODE @NODE UsingScanTek "Using ScanTek" @{B}Using ScanTek@{UB} After @{" installing " LINK Installation} you can start ScanTek from CLI or the Workbench. @{" Configuration " LINK Configuration} Tayloring to your needs @{" Scanning " LINK Scanning } Scanning @{" Menus " LINK MStructure} The Layout of the Menus @{" Windows " LINK WLayout} The Layout of the Windows @ENDNODE @NODE Configuration "Configuration" @{B}Configuration@{UB} 1. Select the menuitem >Settings/SCSI...< · Set the SCSI and scanner SCSI according to your @{" SCSI system configuration " LINK WSCSI}. The SCSI must be same as the SCSI ID which is set with the push-indexing or rotary switch on the rear panel or the underside of the scanner. Any ID from 0 through 6 is valid as long as it is not used by any other device on the SCSI bus. · The should be set as large as possible, because the scanner performs better with a large buffer. If the buffer is not large enough to receive the whole scanned image, then the scanner fills this buffer and stops until the data is processed. Then the scanner continues to scan the next portions until the whole image is scanned. · The size is not as important as the size. A value of several kBytes may also work well. · The and are only allocated during the scanner access and you should ensure that the specified memory is available at that time. · The memory types and can be modified to speed up the SCSI performance on certain SCSI host adapters. You may test the various memory types and choose the one that performs best or reliable. · Examine your SCSI settings by clicking the -Button and wait for the delivered information in . ScanTek has checked, if the given SCSI parameters and the related SCSI device is suitable. · Click to accept your new settings or to forget it. 2. Select the menuitem >Dir Paths/Scanned Pics...< and >Dir Paths/Temp. Files...< · Set the initial default directory path, where the scanned images or the temporarily needed files should be located. · The temp directory should never be located in RAM. You should better set the to a higher value to increase the scanning performance. 3. Select the menuitem >Settings/Screenmode< · You will get a screenmode requester, where you can choose a new screenmode or change the color depth, ie. the number of screen colors. · If the screenmode requester does not appear, you must get a newer version of the ASL library, that supports the screenmode requester. 4. Select the menuitem >Settings/Save Settings< · You can save your current settings to a file. The default settings file name is 'ScanTek.cfg'. This file will be read during startup of the program. · With the menuitem >Settings/Load Settings< you can read a different settings file. @ENDNODE @NODE Scanning "Scanning" @{B}Scanning@{UB} After starting and @{" configurating " LINK Configuration} ScanTek, we can start to scan. 1. Place the desired object you want to scan on the scanner 2. Define the @{" maximum size " LINK WMaxFrameSize } of the scanning or preview frame for further operation 3. Size the @{" Preview Window " LINK WPreview} as large as you want it to 4. Set the desired scanning mode · Click the -Button until your desired scanning mode appears. · Click the -Button to change the parameters of the actual scan mode. Each scan mode has an Options Window. Even if the options window look similar, the options of each scanning mode are independent from another. 5. Getting a preview picture · Click the -Button in the @{" Main Control Window " LINK WMainControl} or select the menu item >Project/Preview<. · The scanner starts to scan a preview picture and displays it in the Preview Window. · The preview picture will be shown dependent on the chosen scan mode. scan mode | preview scan mode -------------------------------------------- red | red grey | grey blue | blue green | green color | grey halftone | halftone black&white | black&white | · The size of the preview picture depends on the size of the Preview Window. · During the scan the @{" Scanner Access Window " LINK WScannerAccess} is open and shows the scanning status. 6. Set the scanning frame in the Preview Window · Press the left mouse button, hold it and move the mouse until the scanning frame is as large as you want it. · The dimensions of the image defined by the scanning frame are shown in the Scanning Frame Box. These figures are only approximate. · There is no real limitation of the scanning frame. If you choose a very small scanning frame then the scanned image may not look good in rare cases. Seize your scanning frame bigger and you will be happy again. 7. Set the scanning resolution · Move the -Slider to the desired resolution setting. (dpi = dots per inch). A high dpi value leads to more dots scanned per inch and to a larger scanned image. Take care of the moiree effect as described in @{" Trouble Shooting " LINK TroubleShooting}. 8. Start the scanning process · Click the -Button in the Main Control Window or select the menu item >Project/Scan<. · You will get a file requester, where you can define the file name for the image to scan. · During the scan the Scanner Access Window is open and shows the scanning status. · The scanned image will be written as uncompressed IFF File with either 1, 8 or 24 bit color depth. · If your is smaller than the picture to scan, then ScanTek will use temp files for saving. The scanning process will be divided into several scanning accesses until the image is completely scanned. @ENDNODE @NODE MStructure "Menu Structure" @{B}Menu Structure@{UB} Project |-- @{" Scan " LINK MScan} |-- @{" Preview " LINK MPreview} |-- @{" About...

The size of this window can be modified. During preview scanning the dimensions of the window are taken to calculate the size of the preview image. The preview will be scanned with a higher resolution, if the preview window is larger. The aspect ratio of the usable scanner flatbed is considered as well. The preview image is surrounded by a border frame, that shows the maximum size of the image. Within the border frame it is necessary to set a scanning frame. The scanning frame is set by pressing and holding the left mouse button and than move the pointer to the desired location. During this movement the scanning frame is updated. If you release the left mouse button than the scanning frame is set. In the @{" Main Control Window " LINK WMainControl} the actual dimensions and memory size of the image to be scanned are shown. @ENDNODE @NODE WScannerAccess "Scanner Access Window" @{B}Scanner Access Window@{UB} This window appears during scanning. It informs about the actual status of the scanning process. @{U}S@{UU}top : Click to stop or abort the actual scanning process. This event can be delayed due to the fact, that the transfer of raw data from the scanner to the can not be interrupted immediately. This may lead to the fact that the actual scanning action can not be stopped. @ENDNODE @NODE WSCSI "SCSI Window" @{B}SCSI Window@{UB} This window must be used to set and to enable the SCSI scanner @{" configuration " LINK Configuration}. @{U}D@{UU}evice Name : The device name of the used SCSI host adapter.

If you want, that the filename of the scanned image should be inserted in the command then you should insert %s at the appropriate position. @{U}?@{UU} : Opens a file requester, where you can choose an external program. If you select the external program, then the full path and the filename are valid as executable. You may add %s if you like. @{U}S@{UU}tart Executable : Tag this gadget, if you want the external program started. S@{U}y@{UU}nchronization : This gadget lets you set the type of execution. Synch: ScanTek will wait until the launched external program terminates. If an startup error occurs during the execution of the external program then there will be an notification requester. Asynch: ScanTek does not wait and continues to work without any relations to the launched program. There will be in rare cases an notification requester, since the error information is no more relevant. Test your external program in Synchron mode and if this works fine, then you may switch to Asynchron mode. @{U}C@{UU}ancel : Throw away changes. @{U}O@{UU}K : Accept changes. @ENDNODE @NODE WMaxFrameSize "Max Frame Setting Window" @{B}Max Frame Setting Window@{UB} This window enables you to edit the maximum size of the preview frame. With this settings you can optimize the preview frame, if your object to scan does not cover the whole flatbed. Additionally it is very helpful, to avoid problems with "Illegal scanning frame". The scanning frame maximum size can be set in parts of 1/8 inch. @{U}W@{UU}idth : The new maximum width of the scanning frame. @{U}H@{UU}eight : The new maximum height of the scanning frame. @{U}C@{UU}ancel : Throw away changes. @{U}O@{UU}K : Accept changes. @ENDNODE @NODE Registration "Registration" @{B}Registration@{UB} ScanTek is shareware.

" LINK WSCSI} · The scanner is not ready (the READY lamp is blinking). -> Wait until the READY lamp is on or you have to reset the scanner by switching it off and on. · The scanner may not be mounted, if you switch it on after the AMIGA has booted. Reboot the AMIGA or remount the scanner with an appropriate tool. · During scanner operation there is a SCSI error. An SCSI error will be generated by the SCSI device handler. It denotes an error on the lower protocol layer. In most cases, there is an invalid SCSI bus termination, which will lead to this failure. · The SCSI bus hangs up during the scanner access. --> You may check your termination on the SCSI bus, since the scanner is not terminated internally. You may have to connect an external SCSI termination plug as well as terminate the SCSI bus correctly. The SCSI bus must be terminated on both ends. These is necessary, if you have problems with SCSI errors. --> You may have to change the order of the discrete SCSI components. · There is a kind of pattern over the scanned image and the scanned image looks not good. -> This may be caused by a moire effect. You have possibly scanned a raster print. Each printed paper has its own dpi rate. This dpi rate overlaps with the scanners dpi rate and leads to the mentioned moire effect. The only solution is to increase the scanner resolution to a value, that is more than twice as high as the dpi rate of the print. As a rule of thumb the dpi rate of rastered prints goes from 100 to 150 dpi. If you get this moire effect you should choose a resolution of 200 to 300 dpi. If nothing of the above mentioned first aid methods lead to a conclusion, then you may give me a @{" bug report " LINK BugReports}. @ENDNODE @NODE BugReports "Bug reports" @{B}Bug reports@{UB} If you find something strange in the behaviour of ScanTek decide for yourself, whether it is a bug or a feature. If it is a bug, there is a way to get additional information. You must tell ScanTek to generate a LOG file. From CLI: ScanTek debug From Workbench: Set the TOOLTYPE DEBUG=ON With this startup value ScanTek generates a text file called 'ScanTek.log' that may contain some important informations about several scanner operations. Try to localize the bug and send @{" me " LINK TheAuthor} the file 'ScanTek.log'. Finally the bug report should contain the following items: · The file 'ScanTek.log', if it is a scanner interworking problem. · Your AMIGA configuration: Model, RAM, OS-Version, accelerator board, graphic card, SCSI host adapter and SCSI components · Your scanner model type Any suggestions on ScanTek, this guide or other things of interest are welcome. @ENDNODE @NODE Copyrights "Copyrights" @{B}Copyrights@{UB} The program ScanTek is © Copyright 1995 Waldemar Zöhner.
