6. Printer-specific Adjustments (GA-1211)
6.1.5 To Calibrate Measurement Page (Target) in Both Directions
Explanation
The density level of gradation steps on the Measurement Page to be used for the calibration (except for ColorCal)
of the GA-1211 changes in the direction perpendicular to the paper feeding direction when it is printed on A4/LT
paper. If a density difference exists on the page either at the front or rear side of the MFP, a satisfactory calibration
result may not be obtained (e.g. dark steps in the pattern are smudged, light steps become darker or the whole
pattern becomes lighter).
Basically such problems must be corrected by the adjustment of the printer engine. However, if the correction is
difficult, they may be resolved by changing the direction of the Measurement Page (its steps are to be parallel to
the feeding direction) before printing.
To change the direction of the gradation steps for A4/LT paper, follow the procedure below. Note that the density
difference on the front or rear side may not be corrected by following this procedure.
Procedures
* Both the service technician and the user can use all the procedures.
(1) Place A4-R or LT-R paper on the bypass tray of the MFP.
(2) Insert the User Software disk to a computer. Then confirm that files” Standard21.ps” and “Standard34.ps” are
stored in the “Windows Color Files\Calibration Files\PS Files” folder.
* ”Standard21.ps” is for a 21-patch chart for A4-R/LT-R, and “Standard34.ps” is for a 34-patch chart for
A3/LD. Do not mix with “Custom21.ps” or “Custom34.ps”.
