Adjustment
Initialize PF The deterioration amount of the PF Roller Shaft is reflected to
deterioration offset the paper feed correction amount. Every time a sheet of paper is
fed, the deterioration amount is counted on the basis of the
original counter value setting.When the PF Roller Shaft or
Printer Mechanism has been replaced during repair, the PF
deterioration counter must be reset.
Disenable PF The PF deterioration compensation counter can be reset only
deterioration offset when the PF Roller Shaft is new. To reduce the ancillary work in
servicing, enter the maximum value (value for which
deterioration compensation is not made) if the PF Roller Shaft
has not been replaced.
First dot position This function adjusts the print starting position in the CR main
adjustment scanning direction.
PW adjustment This adjustment is made to correct the PW Sensor mounting
position on a software basis to improve a paper detection error
caused by the variation of the mounting position.
Head angular adjustment This adjustment is made to correct the error in the Print Head
mounting position (Head angle) to make the nozzle line straight
with respect to the paper feeding direction. Angular
displacement is also checked for.
Bi-D adjustment This adjustment is made to correct the print timing in the go and
return paths in bi-directional printing.
BAND printing This adjustment is made to correct the mis-alignment of vertical
adjustment lines and timing of printing at monochrome draft printing.
PF adjustment This correction is made when the actual paper feed amount
differs greatly from the theoretical value due to paper slip, PF
roller tolerances, etc. during paper feed for printing.
PF band adjustment This corrects variations in paper feed accuracy in the band print
mode to achieve higher print quality.
