See figure 1.1.

The ILFOLAB 1250RC variable speed dryer is designed to dry
ILFORD black and white resin coated papers to a very high
standard. The dryer will dry up to 380 20.3x25.4cm
(8x10 inches) prints per hour, and has a maximum feed width of
50.8cm (20 inches).

For uniform drying and greater efficiency, prints are dried by
infra-red, fan assisted heaters. The print transport speed is
variable for precise control of a wide range of drying conditions
and materials.

This manual gives full instructions for installing and operating the
ILFOLAB 1250RC dryer. For ease of description, it is assumed
the left and right hand sides of the dryer are determined when
facing the dryer at the paper feed (front) end.
