If the NikonScan app can't see a SCSI attached scanner, then usually the Windows computer needs 
the Adaptec ASPI driver installed too (in addition to the SCSI board AHA-2940 driver). 
 

II. Tools needed: 

 
1) Set of jewelers screwdrivers, needs both flat bladed and Phillips tips. As a minimum, a set of 6 
from Radio Shack $8-10 (Archer Japan) will do. A quality set from Felo Cat# 280-907-06 kit of six 
double hex shaft tips plus handle with knurled nut clamping chuck (Germany) $40 is better, 
especially their Phillips #0 size (UPC 4007157-507235). 
 
A separate Wiha brand Cat#261 Phillips #1 screwdriver ($7 Germany) is also highly recommended 
for its precision tip that fits screw heads perfectly, even under high-torque stress and has a 3" long 
round shaft and rigid handle for hard-to-reach mechanism screws. The Wiha tip is machined so 
precisely that screws seem to stick on the tip without being magnetic. 
 
May need a medical-type hemostat, forcep or tweezer to pick out dropped and re-position tiny 
screws. Available at an unusually complete Ace hardware store, such as Seven Corners Hardware, 
St Paul, Minnesota, (651) 224-4859 7corners.com, with an upstairs nationally-rated catalog mail-
order operation at (800) 328-0457  
 
2) DuPont Teflon Multi-Use Lubricant, sets up dry, Cat# D002101, UPC 036121-176232, 2 fl oz, 
mfgr & distrib Finish Line, Inc, 1545 5th Industrial Ct, Bay Shore, Long Island NY 11706, (631) 
666-4186; a fine particulate teflon carried in a evaporative petrochemical dispersing vehicle, or 
equivalent
