Sub-Function ADJUSTMENT
S AGC Position
AGC (Automatic Gap Control) 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 paper of various thicknesses.
The gap adjustment will automatically take place whenever paper is inserted
S after the paper source has been changed
S from park position
S after Power On
S after the printer has been in the STOP mode
S 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 in steps of
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, measurements of the paper
thickness at various positions can be executed 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 Appendix D
and E Quick Reference.
