Change the value of any of the margin settings.

top before the bottom margin.

25 to +25 Increasing the value moves the image toward the right margin. Always
adjust the left before the right margin.
Right Margin -30 to +30 Use this to adjust the printhead.

margin does not alter the margins and should only be used to adjust the printhead.
Print Tests
The Print test determines if the printer can print on media from any of the paper input sources. Each of the installed
sources is available within the Print tests menu.
The content of the test page varies depending on the media in the selected input source. If the selected source contains
paper, then a page similar to the Quick test page is printed, but without the print registration diamonds. If the selected
source contains envelopes, then an envelope print test pattern is printed. This pattern contains only text, which consists
of continuous prints of each character in the selected symbol set. If Continuous is selected, then the envelope print
test pattern is printed on the first envelope; the rest are blank.
The Print test page always prints single-sided, regardless of the duplex setting or the presence of the duplex option.
To run the Print Test:
1
From the Diagnostics menu, navigate to Print Tests .
2
Select the paper source.
3
Select any of the following:
• Single—Prints a single Print test page (no buttons are active while the test page is printing).
•
Continuous—Continuously prints the Print test pages until is pressed.
Print Quality Pages
This enables the user to view the values of the printer settings and to test its ability to generate acceptable printed
output.
The report consists of four pages. The printer always uses media from Tray 1 to print this report. It will not prompt for
a change in media regardless of the media type in Tray 1.
Note: This test cannot be canceled after it has begun. If duplex is activated, then the report is printed in duplex.
To print the Print quality pages:
From the Diagnostics menu, navigate to Print Tests > Print Quality Pages .
