mThe SCSI connection may not be secure.

Make sure the SCSI cable between the scanner and the Macintosh is securely fastened. If the scanner is part of a SCSI chain, check all the SCSI cables.

When I try to scan, I get a message that says, “The application can’t find the scanner.”

mYou may not have properly installed the scanner software.

Review Chapter 3, “Installing the Scanner Software,” and then reinstall the software.

mYou might have a conflict between the Apple Color OneScanner driver and another system extension.

See your Macintosh user’s manual or Macintosh Guide, Apple’s online help system, for information about resolving system conflicts.

mThe scanner may not be on.

Check the power light. If it’s off, shut down the Macintosh, switch the scanner on, and then restart the Macintosh.

mThe SCSI ID number or termination may be incorrectly set.

Check the setting for the SCSI switch on the back of the scanner. See Chapter 2, “Setting Up the Scanner.”

Everything on my monitor screen is frozen.

mYour system is hung.

Turn the scanner off, wait ten seconds, and turn it on again. Then restart your Macintosh.

When I switch the scanner on, its power light goes on briefly and then goes off.

mThe power cord may be loose.

Make sure the power cord is securely inserted in a grounded three-pin power outlet. If plugging the cord in doesn’t solve the problem, you may have a serious hardware problem. See your authorized Apple service center.
