AGC Position
AGC ( A utomatic G ap C ontrol) is an integral part of the paper handling
capabilities of the printer. It is an automatic adjustment function which
ensures an optimal print quality when using various paper thicknesses.
The gap adjustment will automatically take place whenever paper is
inserted

an AGC command has been issued.
The reference point for the measurement of the paper thickness is the
AGC Position of the first print line. Default for the horizontal AGC Position
is 24 (= ink ribbon exchange position), any position from 4 to 131 (at 10
cpi) can be selected.
An adjustment of the AGC Position is only necessary if a measurement at
the default position does not reflect the paper thickness of the area to be
printed on or if there is a paper edge (e.g. of a label) in that position (the
measuring process requires a plain paper-surface).
In addition to the automatic AGC function, random measurements of the
paper thickness can be invoked by the AGC command, or a specific platen
gap can be set using the PCC command. This is to meet the requirements
of forms with complex properties. For details see the Programmers Manual
for the printer.
