Scanner is not a choice in the Acquire/Import command (Apple Power Macintosh Systems)

Either the Adobe Photoshop plug-in was not installed properly, or it was installed in the wrong file or folder. Repeat the installation procedure.

The plug-in should reside here: Photoshop 5.0 (and above) folder > Plug-ins folder > Import/Export sub-folder.

 

Scanner is not a TWAIN option ( Windows Systems)

Either the TWAIN driver was not installed properly, or it was installed in the wrong file or folder. Repeat the installation procedure. Download the latest mini-driver version from the Adaptec Web site (www.adaptec.com).)

 

Error Message: Use an updated version of Adaptec ASPI and/or Adaptec EZ-SCSI Software

Download the latest Advanced SCSI Programming Interface (ASPI) driver version for your operating system from the Adaptec Web site (www.adaptec.com).

 

TWUNK Error When Launching TWAIN Driver

The problem is the difference between 16-bit and 32-bit TWAIN components. When a 16-bit TWAIN driver calls on a 32-bit TWAIN data source, the operating system generates a TUWNK_16 error. To avoid this error, use a 16-bit TWAIN data source with 16-bit host software, and a 32-bit TWAIN data source with 32-bit host software. Here are some examples:

Software

Version

TWAIN Data Source

Adobe Photoshop Software

2.5 - 3.04

16 bit only

3.05* - 4.0

16 bit or 32 bit

5.0, 5.5, and later

32 bit only

Micrografx Picture Publisher

3.0 - 5.0

16 bit only

6.0 - 8.0

16 bit or 32 bit

* Photoshop v3.05 requires an update which is available from the Adobe Web site (www.adobe.com).

 

Image appears blank after a preview or a scan

You are probably scanning either the unexposed portion of the film or an empty portion of the film holder. Verify there is film in the film holder and the film scene content is in the proper position for scanning.

 

The scanned image has spots, dimples, and unwanted shapes.

These anomalies are caused by dust on the diffuser glass. The dust was either introduced after the last calibration or is too large for the scanner to completely 'calibrate out.' The software user interface provides an optional Recalibrate button which may correct minor dust accumulation once a proper focus is obtained.

 

The scanned image is the reverse of the original

Is the film in the film holder backwards? If it is backwards, replace the film into the holder with the film holder showing the correct reading, 'R', on the plate. When the film is placed in the film holder, the film edge code should be 'right reading.'
Note: When the film is placed in the film holder, the film emulsion should be on the "wrong reading" side of the film and should be facing away from you.

 

The scanned image is the negative of the original

This occurs when the wrong film term is used; for example, selecting a positive film term when scanning a negative, or selecting a negative film term when scanning a positive.

 

If the scanned image has a dominate color, the rest of the colors are out of balance.

The film was probably scanned with the Autobalance feature deselected. Make sure the Autobalance option is selected and select Preview (to re-scan the image) or select View Changes (to observe the effects of the Autobalance feature).

 

Some images look like they are scanned on top of another

This happens when the scanner is calibrated with a piece of film in the film gate. Remove any film from the film gate and use the Recalibrate button in V3.4 software to recalibrate the scanner.

 

Scanned images appear out of focus

  • Select a preview image on the monitor.

  • Use a crop box to focus on a smaller portion of the image (at least a 500 x 500 pixel area).

  • Scan the image and view it at a higher magnification in the image editing software. Confirm the image quality.

    Note: This is the recommended procedure even though the scanner automatically focuses the first time an image is scanned. If the image still appears out of focus, repeat this procedure a few times. If the condition persists, power cycle the scanner and repeat the procedure.

  • Select a different film with good image quality to verify the out-of-focus film was focused properly.

 

A loud, grinding noise is heard after powering on the scanner; Magnification Hardware error appears

Generally this indicates a hardware or electrical circuit board problem. Power down the scanner and retry the power on sequence a few times. If the condition persists, service is probably required. See the Repair Information Web page. Do not return your equipment without prior authorization from Kodak.

Note: Mechanical movement is normal during power on, focusing, and calibration procedures, and should not be interpreted as a problem.

 

Error message "New Hardware Found - Unknown Device" appears multiple times when booting up Microsoft Windows 95 software.

Are the device drivers updated to the latest version? Normal operation displays this message once. If the drivers are not updated, the message appears seven (7) times! You can either acknowledge the error message each time it appears or, preferably, download the latest device driver version from the Adaptec Web site (www.adaptec,com).

Which version of the aic78xx.mpd is being used? To determine this, look in the C:\windows\system\iosubsys directory. Versions 1.20 and 1.21 are known to cause this problem. Versions 1.01a and 1.23 or later function normally.

 

A SCSI hard drive problem occurs when operating the scanner on my computer

If you use a Kodak Professional RFS Film Scanner TWAIN compliant driver with a Windows based computer, do not connect a SCSI disk drive to the same SCSI adapter board that is attached to the scanner. You must install a second Adaptec SCSI card.

 

Scans result in extremely small or partial images

There are two possible causes for this situation: the crop box was not de-selected after performing a focus, or an area of the original image was inadvertently cropped. When you use the crop feature to focus on an image, make sure the mouse does not move prior to selecting the scan button. Mouse movement inadvertently creates another, smaller crop box. Make sure the correct image size is selected before you scan.

 

Scans show ghosting or double image artifacts

Unfortunately there are no adjustments or on-site repairs that can be made to solve this problem. See the Repair Information Web page. Do not return your equipment without prior authorization from Kodak.
