capabilities of the printer. it is an automatic adjustment function which nsures an optimal print quality when using paper of various thicknesses. the gap adjustment will automatically take place whenever paper is inserted
1 from park position
2 after power on
3 an agc command has been issued.
4 manual insertion (only printer without cutter)
agc (automatic gap control) is an integral part of the paper handling
5 after the paper source has been changed
6 after the printer has been in the stop mode
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 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 e, and f quick reference.
process requires a plain paper-surface). requirements of forms with complex properties. for details see appendix d,
2 platen gap
this adjustment is to be seen as a correctional offset to the platen gap set by the agc (automatic gap control) function or a pcc (programmable copy control) command. it effects all paper paths. the offset is within the range of -3 to +4. one step is equal to 18 μm.
"-" reduces the gap, "+" increases it.
this setting should only be changed in exceptional case. the optimum setting of the platen gap will be done automatically by the agc or pcc
3 agc adjust
this is a basic adjustment which is automatically performed at the initial power on of the printer, and which thereafter only needs to be initiated after having exchanged the print head or the platen. it is essential that the ink ribbon is installed and no paper is in the printer when this procedure is started. after activating this procedure, the printer displays
4 paper-in adj (paper-in-sensor adjustment)
this parameter logically adjusts the base position of the run-in-sensor. the factory set value is such that the default is set to compensate specific mechanical tolerances. the adjustment range is from -3 to +4 in / " steps 1 60 (0.42 mm), where "-" means an upward movement and "+" a downward movement. when implemented, the adjustment applies to all paper paths.
5 cut. v-pos lo. / cut. v-pos up. (vertical positioning for cutting device for the printer with cutter or for the tear off edge on the printer without cutter)
this can be set differently for each paper source (lower and upper tractor) and is meant to be a corrective parameter to meet variations in paper size and pre-printed material.
if, for some reason, it is not desired to cut exactly on the perforation it is very important to cut below the perforation of the printed page. if the paper is cut above the perforation the remaining paper can easily bend and cause a paper jam. do not cut through a label as the blad would get dirty by the glue.
the following table shows the possible values in inch and millimetres.
6 uni-direct.cmd
if no is selected, commands for uni-directional printing will be ignored. the default setting of yes means that commands will be carried out to switch from bi-directional to uni-directional or vice versa.
7 tract. ff-mode (tractor form feed mode)
execute ff means, every form feed sent to the printer will be executed. if you set ignore ff, only a form feed before printable characters will be executed, that means blank pages will be avoided.
