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:
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

Start-Up 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
flat-blade 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 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.
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.
Note:

General Troubleshooting
No LED (no power) 1 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.
3 With power off, reconnect the optical assembly at J301.
Turn on power and check voltages at 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
4 If any voltages are not correct, replace the power supply
board.
5 Turn 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.
6 Turn off scanner and reconnect J301.
7 With 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.
8 Turn off scanner and reconnect J311.
9 With power off, remove connector J306 from the logic board.
10 Turn on power and recheck voltages at J101. If readings are
within specified ranges, replace the home position sensor
and/or home position sensor cable.
11 Turn off scanner and reconnect J306.
12 With power off, remove connector J309 from the logic board.
13 Turn 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.
14 Turn off scanner and reconnect J309.

“Scanner does not find Home sensor” in this chapter.
4 With the scanner on, check voltages at connector J101.
J101 DC Voltage
GND-1 4.75 to 5.25

6 Turn off power and check resistance in the drive motor by
measuring at connector J311.
J311 pins Resistance
1 and 2 About 17.3 ohms
