The following lines are drawn on the second side of the page.
Figure 40: Back side of the calibration page
These lines are printed in such a way that when you hold the calibration page against a
light source (such as a overhead light, a light table, or a window) the lines on the back
side of the page are visible and appear to align with the grid lines on the front side. You
then can choose the numbered lines on both the X axis and the Y axis where the front
and back grid lines match up.
For each axis, one line from the back side of the page should appear to line up closely
with a numbered line on the front side. The number on the front side is the value that
should be entered for the appropriate tray’s X and Y offset values. The lines on the front
and back grids are spaced so that only one pair of lines in each axis will appear to line up
better than the other ten pairs of lines. The arrows on the calibration page show the
current offset value stored in the printer's NVRAM.
Accessing the duplex registration menus
Access to the Duplex Registration calibration pages and settings is provided through the
printer's control panel.
On the HP LaserJet 8150 printer control panel display, use the MENU key to move
through the available menus until DUPLEX 0REGISTRATION MENU appears. Press the
ITEM key to scroll through the available media tray settings. Use the -VALUE+ key to
enter the value for both the X and Y offsets. The valid range of values you can enter is
from -5 to 5.
NOTE: DUPLEX REGISTRATION menu appears only when a
duplexing unit has been installed correctly in the printer.
