The menu tree for the Duplex Registration menu appears as follows:
DUPLEX REGISTRATION MENU
TRAY 2 PRINT TEST PAGE
TRAY 2 X = 0 *
TRAY 2 Y = 0 *
TRAY 3 PRINT TEST PAGE
TRAY 3 X = 0 *
TRAY 3 Y = 0 *
TRAY 4 PRINT TEST PAGE
TRAY 4 X = 0 *
TRAY 4 Y = 0
Menu items for TRAY 1 do not exist. This is because in most cases, the multipurpose or
MP (manual feed) tray, otherwise known as tray 1, does not have close enough margin
registration tolerances to make calibration attempts useful.
The menu items for TRAY 4 will only appear if an external paper-handling device is
present. If an external input device has more than one paper tray, the TRAY 4 settings
apply to all paper trays in the external device, because all the external input device trays
feed through the VTU (vertical transfer unit), which is the registration point for external
input devices.
Using the duplex registration calibration page
The following instructions appear on the calibration page to assist you in calibrating the
duplexing unit with the printer's input paper trays.
Modifying the registration value
1. Hold this page up to a light source and choose the number on each axis where
the lines on the front and back of the page align most accurately.
2. Press Menu until DUPLEX REGISTRATION MENU appears on the printer
control panel display.
3. Press Item until TRAY n X = appears and use –Value+ to enter the number you
selected from this test page in step 1.
4. Press Item until TRAY n Y = appears and use –Value+ to enter the number you
selected from this test page in step 1.
5. Press Item to scroll up through the duplex registration menu until PRINT TEST
PAGE appears for TRAY n.
6. Press Select to print the page.
7. Repeat step 1 to verify that the lines on the front and back of the page are
properly aligned.
NOTE: In steps 3, 4, and 5, the 'n' should be replaced with the
number of the paper tray from which the test page was
printed.
