Not at work so I can't be sure about this model. Does it have a sheet feeder on
the scanner. (ie can you scan from the flat bed OR through a sheet feeder).
If so, try copying both ways and see if there is a difference.
The sheet feeder usually has a seperate window (narrow window the width of the
page) through which the scanner unit "sees" the paper, if the sheet feeder
fails but the flat bed works then this window may need cleaning (dry cloth is
best, denatured alcohol or gentle household cleaner if necessary). Another
thought, the internal mirrors may be used differently between sheet feed and
flat bed, there could be a clue there and maybe cleaning the mirrors would be
needed but only if one method of copying works and the other one fails.
There has to be a difference in the way the internal electronics operate when
scanning versus copying (different signal paths are opened up). If the results
are the same from sheet feeder and flat bed then I would change the scanner
bulb (sounds silly????, could be that it is on the edge of failure and the
difference in logic between scanning and copying is enough to make the
difference).
I assume it is not under warranty? If so then call your friendly local Brother
agent. You may want to call them anyway but I guess it will cost something to
do so.

I have a brother MFC-9600 Printer/Scanner/Photocopier/Fax comobo unit.
Recently I found out the photocopy doesn't work right. It would
produce a very light print out similar to a unit very low on toner.

The unit has plenty of toner left and the laser printing unit is in
perfect order as it makes good, black prints when I send a print job to
it from my computer.

The scanner also produces good contrast when I scan to computer from
the unit.

I checked copy settings such as "document type" and "contrast" from
maximum to minimum, but the unit continues to produce very light
prints. Since the scanning and printing units are both in good working
order, I don't understand why photocopier function won't work
correctly.

Any clue?
