I also have a PL III and have noticed the same problem. The solution
for the worst tramlines is pretty simple: at the very front of the
scanner is a narrow window about 5/8" tall by 9 3/4" wide, and there is
a matching window on the transparency head. Make sure *both* are
scrupulously clean (on *both* sides of the glass) -- any dust or marks
in this area of either the transparency head or of the flatbed will be
seen as CCD cells that need additional amplification, and that really
messes up the scan.

To clean the inside side of the glass of the transparency head you will
have to remove the four small screws near the hinges and that cover
plate, as well as the four large screws near the glass area. Then you
will have to partly remove the glass carrier so you can remove the
screw holding the grounding strap (a green wire) which allows you to
remove the glass carrier completely for cleaning.

Have fun,

Hello there.

I'm a greenhorn scanner with a frustrating problem.  I have a umax
powerlook 111 with the tranny adapter.  I've got DUST problems that
cause
vertical lines to run all the way through the frame from the top to
bottom.
There are several parallel lines like this.
These lines only appear when using the tranny adapter; never when
scanning
prints.  It's been said that the CCD area could be region with the
dust.
Also the calibration chart.
Does the tranny adapter have a CCD area and calibration chart in
addition to
the flatbed region?  If so, how do I find them?  Or should I just ship
the
tranny adapter back to umax to have it cleaned?

Thanks in advance!
