Feeder (ADF) with a 20­sheet capacity paper tray.

Scanner Features

Features of the Color OneScanner 600/27 include the following:
• 300 x 600 dpi optical, 2400 x 2400 dpi interpolated, resolution for improved Optical Character Recognition (OCR) accuracy
• 27-bit scanning depth color that recognizes up to 134­million colors
• Support for PICT, TIFF, JPEG, EPS, BMP, and Photoshop; compatible with most popular word processing, presentation, image-editing, page layout, and web-authoring software for the Macintosh
• OneScanner Dispatcher software that integrates with popular applications and provides the tools to scan, edit, and archive images or documents; supports Drag and Drop
• Small desktop footprint of 16.3 in by 11.3 in
• ColorSync for the closest possible color match between what is scanned, seen on the monitor, or printed
• Xerox TextBridge for converting scanned documents into editable text or HTML format for a Web page
• Optional 20-sheet capacity Automatic Document Feeder

Scanner Operation

Clicking the icon at left launches a MoviePlayer animation sequence that shows the following scanning cycles:
• Flatbed scanning where the document remains stationary and the scanner lamp moves to scan from the front
• Automatic Document Feeder (ADF) scanning where the document moves and the scanner lamp remains in one position to scan from the front
Note:
Also shown in the animation sequence is Transparent Media Adapter (TMA) scanning where the document remains stationary and the TMA lamp moves to scan from the back. This type of scanning is available with the TMA option for the Apple Color OneScanner 1200/30. A TMA option is not available for the Apple Color OneScanner 600/27.

Optical Assembly Handling Precautions

Issue
: The Color One Scanner 600/27 optical assembly is being damaged during removal.
Solution:
by the longer sides (see illustration on next page) so that the printed circuit board (CCD unit) on the underside will not be damaged. The CCD unit is a delicate part located on the front, or shorter side of the assembly. If a service provider grabs or touches the CCD unit while removing or replacing the scanner, the scanner may not function. In addition, new packing was designed for the scanner unit.
Note
Assembly in Take Apart.
Apple recommends handling the scanner assembly
: For additional information, refer to the Optical
Hold or lift the optical assembly by the long sides,
CCD Unit
Mirrors
never by the shorter sides.
Caution:
Do not touch the printed circuit board (CCD Unit) or the mirrors.

Startup Troubleshooting Tips

When scanner is turned on, there is a chattering sound and it will not scan.
When trying to scan from the Dispatch software, this message appears: “Unable to initialize the scanner driver. Either the scanner is not turned on, connected, or already in use by another application.”
The SCSI select switch doesn’t select the correct SCSI ID.
Unlock the scanner by opening the top cover and using a coin or slotted screwdriver to turn the locking mechanism, located at the top of the glass. unlock icon is at 90 degrees from the slot. See the Additional Procedures chapter for more information.
1 The most common cause is that the scanner was turned on
after the Macintosh. Always make sure the scanner is turned on, then turn on the Macintosh. Observe the INITs as the Macintosh starts up. The INIT for the scanner appears as a side view of the scanner. This is the driver loading.
2 If the scanner INIT does not appear, reinstall the scanner
driver. If the icon appears with an “X” through it, there is a SCSI problem.
3 Check the SCSI ID and cables.
The label may not be lined up correctly to the position of the switch. Put the switch in the 12 o’clock position and then count to the correct SCSI ID.

1 Make sure scanner optical assembly is unlocked. See
Additional Procedures chapter for information. 2 Check connections at J307 and J311. 3 Remove optical assembly and turn on scanner. If motor
works, make sure the glass is oriented correctly. Go to
symptom “Scanner does not find Home sensor”. 4 With scanner on, check voltages at connector J101.
J101 DC Voltage
GND-1 4.75 to 5.25
GND-3 11.4 to 12.6
GND-6 21.6 to 26.4
5 If any voltages are not correct, go to symptom “No LED,
no power” in this chapter. 6 Turn power off and check resistance in the drive motor by
measuring at connector J311.
J311 pins Resistance
1 and 2 about 17.3 ohms
3 and 4 about 17.3 ohms
7 If resistance is not correct, replace drive motor. If
resistance is correct, check connection at J311 and if it
is normal, replace logic board.
Troubleshooting Symptom Charts/General Troubleshooting - 6
Problem with lamp intensity checked or origin of scan area
Scanner does not find Home sensor; scanner drive motor does not move mirror, even when optical assembly is removed
When the Apple Color OneScanner Plug-in is moved to the Photoshop Acquire folder it doesn’t work. The Dispatch doesn’t work either.
When using the Automatic Document Feeder (ADF), the scan shows a blank page or a strange vertical pattern.
1 Make sure glass is oriented correctly and that nothing is
blocking the black strip or upper portion of the glass. 2 Replace glass.
1 Inspect mirror assembly on optical assembly for damage
to the home position flag. Replace optical assembly if
needed. 2 Replace home sensor (photo-interrupter). 3 Replace logic board.
The Apple Color OneScanner Plug-in must be left in it’s folder. You can make a copy of it, or an alias and put that in the Acquire folder. You cannot change the name of the original plug-in. It must keep the name “Apple Color OneScanner”.
Check to see if paper has been left on the flatbed. Before using the ADF, always check to see that the flatbed is empty.
Cannot fax multiple pages with the ADF.
ADF does not feed paper to scanner
Scan each page and merge them together before faxing them.
1 Check connection at document feeder connector cable. 2 Close document feeder cover completely. 3 Verify that document originals in the feeder are standard
office papers and do not exceed the maximum thickness of
2 mm (5/64 in) or 20 sheets. 4 Verify that document originals are free from
• Tears, perforations, or punch holes
• Curls or wrinkles
• Carbon backing or coarse texture
• Labels, tape, or glue
• Staples or clips
5 Replace logic board.
