Scanner Operation
Clicking the icon at left launches a MoviePlayer animation sequence that shows the three 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
• Transparent Media Adapter (TMA) scanning where the document remains stationary and the TMA lamp moves to scan from the back

Optical Assembly Handling Precautions
Issue: The Color One Scanner 1200/30 optical assembly is being damaged during removal.
Solution: Apple recommends handling the scanner assembly 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: For additional information, refer to the Optical Assembly in Take Apart.

General
The Symptom Charts included in this chapter will help you diagnose specific symptoms related to your product. Because cures are listed on the charts in the order of most likely solution, try the first cure first. Verify whether or not the product continues to exhibit the symptom. If the symptom persists, try the next cure. (Note: If you have replaced a module, reinstall the original module before you proceed to the next cure.)
If you are not sure what the problem is, or if the Symptom Charts do not resolve the problem, refer to the Flowchart for the product family.

Symptom Charts/Normal Start-Up Sequence (Flatbed Scanning) |
|
|
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.”
Symptom Charts
Normal Start-Up Sequence (Flatbed Scanning)
Important: Disconnect the scanner’s SCSI cable before beginning the start-up sequence. Even when turned off, some computers will not allow the scanner’s normal start-up sequence to begin if the SCSI cable is connected.
1 Power on
2 Power LED lights
3 Logic board self-tests
4 Lamp turns on
5 Optical assembly moves to home position sensor at top of glass
6 Lamp turns off, then on
7 Lamp intensity checked with reflection of white on back of glass
8 Origin of scan is determined by black strip on back of glass 9 Lamp moves about 3 mm down
10 Lamp moves back to home position sensor
11 Lamp turns off
12 Ready
Start-Up Troubleshooting Tips
Unlock the scanner by opening the top cover and using a coin or flat-blade screwdriver to turn the locking mechanism, located at the top of the glass. Note: The arrow that points to the lock or unlock icon is at 90 degrees from the slot. See the Additional Procedures chapter for more information.
1The most common cause is that the scanner was turned on after the Macintosh. Always be 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.
2If the scanner INIT does not appear, reinstall the scanner driver. If the icon appears with an “X” through it, there is a SCSI problem.
3Check the SCSI ID and cables.
The SCSI select switch doesn’t select the correct SCSI ID
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.

Check external power cord and incoming voltage. |
|
2 |
Remove the covers, glass, and optical assembly. Check AC |
|
|
voltage to power supply board by turning on power and |

testing for rated AC voltage at the AC input pin (pin L) on the |
|
|
power supply board. If readings are not to rated voltages, |
|
|
replace power supply board. |

4If any voltages are not correct, replace the power supply board.
5Turn off scanner. With power off, remove connector J301 from the logic board. Turn on power and recheck the voltages at J101. If readings are within specified ranges, replace the optical assembly since the CCD driver is faulty.
6Turn off scanner and reconnect J301.
7With power off, remove connector J311 from the logic board. Turn on power and recheck the voltages at J101. If readings are within specified ranges, replace the drive motor.
8Turn off scanner and reconnect J311.
9With power off, remove connector J306 from the logic board.
10Turn on power and recheck voltages at J101. If readings are within specified ranges, replace the home position sensor and/or home position sensor cable.
11Turn off scanner and reconnect J306.
12With power off, remove connector J309 from the logic board.
13Turn on power and recheck voltages at J101. If readings are within specified ranges, replace the LED cable. If readings are not within specified ranges, replace the logic board.
14Turn off scanner and reconnect J309.

1Make sure scanner optical assembly is unlocked. See Additional Procedures chapter for information.
2Check connections at J307 and J311.
3Remove optical assembly and turn on scanner. If motor works, make sure glass is oriented correctly. Go to symptom “Scanner does not find Home sensor” in this chapter.

When the Apple Color OneScanner Plug-in is moved to the Photoshop Acquire folder, it doesn’t work. The Dispatch doesn’t work either.
The Apple Color OneScanner Plug-in must be left in its 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.”
