The calibration of certain laboratory equipment is aided by a
known density sample of the xerographic toner utilized. Dis-
closed is a method of microscope slide preparation that
results in a toner sample of known thickness and area.

Shim stock 1 of a known thickness is used, e.g., .001 to .03
inch thick plastic sheet. The center area of the shim stock is
cut out or punched out in a known area 2. Glue is applied in a
thin layer around the cut out 2 and the shim stock 1 is pressed
onto a first glass microscope slide 3. Toner 4 of the desired
batch or production is placed in the receptacle formed by the
cut out 2. The toner 4 is leveled, using a sharp flat edge,
until it is the same height as the exposed surface of the shim
stock 1. The toner is then sandwiched between a second micro-
scope slide 5, which can be kept in place by gluing the edges
of the second slide 5 with epoxy to the exposed surface of the
shim stock 1. This results in a toner sample slide of known
thickness and area, equal to the thicknesses and area of the
shim stock cut out.
