I have a 17-year old Spectroscan. The oils used in lubrication get oxidized and
become sticky in a couple of years. I have cleaned and applied thinnest of oils
a couple of times but after a couple of year all got oxidized. Finally I
removed all residues of the oxidized lubricants and applied a “dry” lubricant.
The product I have used is Winkel’s “PTFE Dry Lubrication Spray”. CRC’s “Dry
PTFE Lube” appears to be a similar product.
I did this 10 years ago and the Spectroscan has not missed a beat since then.

I guess this may have been all for nothing... My Spectroscan has a bad motor on
the Y axis (I think). As soon as the belt tensions it, the movement gets stiff
(power on or power off) so I assume a bad bearing on the end at the pulley. So
unless I can find another stepper motor with the same specifications, or find a
donor table cheap, this device is out of commission.
If anyone has a scan table that they don't use, or wants to buy a Spectrolino
to go with their table, let me know.

I did some testing back many years ago and didn't see any differences in the
measurements with the smaller patches. The 5.5 was called out as the absolute
minimum size, and thankfully my x-y table was accurate enough over sizes that
small. I'll give it a try when I get a new usb-serial adapter for testing and
report back. Probably take a week or two.

Another question is about the Spectroscan... Having used it on squares I
remember that I needed to touch down on three corners so that the device
new the size of the target. Does this still happen with the hex patches?
Colorport defined the three corners with a number so that you knew which
ones to position and which order to do them in. The hex patches are new to
