Change the value of any of the margin settings.
Top Margin -16 to +16 Increasing the value moves the image down the page. Always adjust
the top before the bottom margin.
Bottom Margin -20 to +20 Increasing the value moves the image toward the top of the page.
Left 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.
Note: The alignment of the left margin positions the black plane to the right or left. The alignment of the
right margin does not alter the margins and should only be used to adjust the printhead.
PRINT TESTS
This test determines if the printer can print on paper from any of the input trays. Each installed tray is available
within the Print Tests menu.
The content of the test page varies depending on the paper in the selected input tray.
•
If the selected tray contains paper, then a page similar to the Quick Test page is printed but without the print
registration diamonds information.
•
If the selected tray contains envelopes, then an envelope print test pattern is printed. If Continuous is
selected, then the envelope print test pattern is printed on the first envelope and the rest of the envelopes
are blank.
The Print Test page always prints one-sided, regardless of the duplex setting or the presence of the duplex
option.
