Perform this procedure when the printed image appears uneven in density across the feeding direction after replacing the photoconductor unit. The line sensor detects unevenness of density in the printed test pages, and the machine compensates for the unevenness with a high degree of accuracy.
Load white paper of A3 size or larger into the paper tray. About 20 sheets of paper are required to perform adjustment.
Press [Adjustment Settings for Operators] in the upper left part of the screen.
Press [Machine: Image Quality].
Press [Density Difference Printing: Across Feed].
Select a paper tray loaded with paper in "Select Tray for Test Print".
Use the slider to specify the tone to prioritize adjustment per color if necessary.
If unevenness appears in the highlights, specify a smaller value. If it appears in the shadows, specify a larger value. To adjust all tones in well-balanced manner, perform adjustment using the default values (K/C/M-5, Y=3).
Press [Execute].
16 test sheets are printed during the automatic adjustment process, and then two confirmation charts are printed.
Check the confirmation charts to confirm that the unevenness of density across the feeding direction is compensated, and then press [Reflect].
Press [Home] (
) at the bottom of the screen in the center.
