Hadn't used my PFP spectro in some months.  When I plugged it in was getting bizarre 
readings: lime green for mid-grays, Lab readings that are impossible for what should be 
black (L=67.27,  a=-167.66 b=115.99  D=.43 when it should be reading over 2.0).

Calibration tile is still normal?  L=89.76, a=-.77, b=-1.43, D=.12

Anyway I had changed from a G4 Tiger to a Dual Core Leopard since the last usage and had 
transferred most of my software through Migration Assistant.  

I trashed the original PFP 2.0 which had been upgraded to SpiderPrint 3.0 and loaded a fresh 
version of SpiderPrint 3.0.1.  Still getting the same bizarre lime green or orange readings on 
a 21 step grayscale with Ds only a fraction of what they should be

Burnt out LED in the spectro, wierd Leopard stuff, Jumbies?  Inquiring minds want to know 
and want to get back to work.

It would not read the white tile correctly if it had a burnt out LED.  
I'd say a communication issue. Try plugging the spectro directly into  
a fully powered rear port on the computer. If that doesn't fix it try  
a different USB cable.

Should have mentioned it in the first post but tried cable change and direct port even before 
reloading the software.  Just now tried it with the older G4 Tiger and a direct port and got a 
similar reddish orange with an impossible Lab value (a=-167) on what should have been a 
Dmax on a glossy paper.
