Test Print 1; Test Print 2 - Lexmark Optra Color 1200 Service Manual

5050-001
The X, Y, and Theta adjustment must be checked with the radar test
page found in the X Adjustment menu, (Test Print) sub menu.
This adjustment depends on the combination of 3 settings for color
registration, X, Y, and Theta. Follow the procedure closely as the
adjustment is critical. For additional information see
Calibration of Printer" on page
1. Press Return and Go as you turn on the printer. Release the
buttons when you see Performing Self Test on the display.
2. Press the Menu button until X Adjustment displays.
3. Select X Adjustment.
4. Press the Menu button until X Adjustment- Print Tests
displays and press Select. This will print the 3 color registration
pages. These pages are the same for X, Y, Theta and for the 3
colors and are available under the X Adjustment, Y Adjustment,
and the THETA Adjustment.
5. There are 3 adjustments for each color registration; X, Y, and
Theta. Adjust X and Y first, then adjust Theta. X controls the
horizontal plane. By adjusting X you move the radar image left
(negative) and right (positive). Y controls the vertical plane and
by adjusting the value for Y you move the color radar image up
(negative) and down (positive). These values are determined by
examining the left side of the radar page. Values for X are
1/600th of an inch and Y values are 1/2400th of an inch.
6. Theta controls the skew or angle of rotation. To get the correct
reading, adjust X and Y before Theta.
7. Examine the left side radar images for their deviation from
black. Look at all the radar images along the left and make a
judgment on the value of the adjustment. When the color is
correctly adjusted, the color radar image should lay directly on
the black radar image.
8. Press the Menu button until the color you want to adjust
displays and then press Select.
9. Change the displayed value and press Select. You should see a
message displayed that the value is Saved.
10. Press the Menu button until X Adjustment - Print Tests displays
and press Select.
11. Look at the color and the value you have changed and see if
this is acceptable. If so, go to the next adjustment. If it is not
acceptable, go back to the color and adjust it again.
