Re: [APML] PPF Test

["Jim Janusz" <jjanusz@dc.rr.com>]

The Powerlook 3000 will do this on thin (underexposed) negatives.  It may be
caused by interference on the Scsi cable or a failure in the scan head.

>From TS:  The single scan I saw appear to have horizontal banding which is
usually attributle to software or SCSI bandwidth interference.

They are no help unless you want to pay for a scanner trade.
