298 Troubleshooting C7085-90921
On each of the color bars in the process section are bolded numbers that indicate the current
number set on the control panel. These bolded numbers will always be in the middle of the bars. To
set the correct value for each of the colors, look at the lines within the bar and find the grouping that
has the color line directly on top of the black line (it will have more white space). Print at least five
registration pages to see if the new settings are correct.
Hint Using a magnifying glass to look at the lines will help in selecting the best number.
Figure 7-20 Registration page
Note Hewlett-Packard strongly recommends that the registration values be selected on the basis
of averaging five consecutive samples.
Setting the registration number:
1 Press the
[ITEM] key to select the appropriate color (cyan, magenta, or yellow) at its registration
number.
2 Press the
[VALUE +/–] key to change the registration number to the one identified.
3 Press the
[SELECT] key to enter the value.
Setting margin numbers
The top margin number is not tray-dependent like the left side margin. Simply print the registration
page from whichever tray has paper. Using a ruler, measure from the top edge of the paper to the
series of lines. Find the line that is 13 mm (0.5 in) away from the paper’s edge.
