printing the following message is displayed. The Power indicator
also blinks while the page is printing.
The printer will attempt to print the Top Margin page from the default
paper source. However, if the default source only supports
envelopes, then the page will be printed from Tray 1. The page
consists of alignment diamonds. When you change the value for that
tray you will see the K alignment diamonds move up and down the
page. The test page also contains the page count setting, printer
serial number, and code levels.
The Test Page can only be printed for the trays that are installed.
The Menus to change the values show up even if the tray is not
installed. This allows the service person to set these values to the
factory values even if a customer does not have that tray installed.
The Test page should be printed on Letter or A4 paper only.
To exit the Registration menu, press Return.
CMY Top Margin Adjust Print Tests
The purpose of this function is to adjust the leading edge margin for
each tray. It is the top margin of how the page is printed. For A4 or
letter it is the leading long edge of the page that the margin is being

edge of the paper reaches the print registration rollers and when the
printer starts putting toner on the paper. You must adjust both the
CMY and K top margins. The K Top Margin must be adjusted first.

3. Select CMY Top Margin Adjust.
4. Input the values.
