Auto Align Adj
The printer automatically runs a Toner Patch Sensing (TPS) diagnostic after certain key events. If necessary,
the printer will automatically adjust the alignment.
If Auto Align Adj is set to Off, then the diagnostic still runs, but the printer will not use the resulting data to
automatically adjust alignment. This could eventually lead to the user having to adjust alignment manually.
Therefore, Auto Align Adj should not be set to Off during normal printer usage.
Color Alignment
When you select Color Alignment, the printer generates several alignment pages. Follow the instructions on the
pages to fine tune the color alignment of the printhead.
Motor Calibration
This test synchronizes the aligner and fuser motor speeds with the transfer belt. Eight blank pages feed during
the test, and all buttons are disabled until the test finishes.
Note: Motor Calibration must be performed using 600 dpi resolution and with duplex disabled.
ADF Edge Erase
The ADF Edge Erase setting specifies, in millimeters, the size of a border around the scanned image that will be
erased. For copies, the printed page will always have a at least a 2-mm no-print border. The larger of the 2-mm
no-print border and the Edge Erase setting will be used in this situation.
FB Edge Erase
The FB Edge Erase setting specifies, in millimeters, the size of a border around the scanned image that will be
erased. For copies, the printed page will always have a at least a 2-mm no-print border. The larger of the 2-mm
no-print border and the Edge Erase setting will be used in this situation.

size.
