Leading Edge Adjustment
The distance from the leading edge of a sheet of paper to the
beginning of the printable area can be adjusted using VR301
located on the DC Controller PCA. Leading edge is set at the
factory for new units and only needs adjustment when the DC
Controller is replaced. VR301 can be accessed without removing
any printer assemblies (other than the paper cassette).

Run a printer engine test (see “Engine Test” earlier in this
chapter). Measure the leading edge distance (see Figure 7-7).
If the distance is 1.5 to 2.5 mm, no adjustment is necessary.
If adjustment is needed, remove the paper cassette from the
printer by sliding it all the way out.
Locate the access hole for VR301 (see Figure 7-7).
Turn VR301 clockwise to decrease the leading edge distance, or
counter-clockwise to increase (see Figure 7-7).
Replace the paper cassette and run another test to compare.
Repeat 1 through 5 until the leading edge is within tolerance.
