Reference A-11
These utilities access Engine Logic Board NVRAM to modify the stored value for
each variable. Changes are made by increasing or decreasing the stored value
changing the image position on the page. For Scan direction adjustments, each
variable is set at the factory to a value of 50. The maximum for scan direction
adjustments is 99 with a minimum of 1. Any change in the scan direction value by one
(1) results in a .254 mm change in the image position.
For the process direction the factory default is 33. The maximum is 66 and the
minimum is zero (0). Changes to the current value for process direction variables by
one (1) moves the leading edge of the image .363 mm closer or further from the edge
of the paper.
Use the Printer NVRAM Adjustment utilities in conjunction with the Print Quality
test print, to modify the general (All Trays) or specific (Tray 1~6) values to realign the
image. See
"Adjusting Simplex Registration" on page 6-6 for instructions on using
the Print Quality test print to evaluate image registration performance.
