• The Secondary Transfer Voltage Adjustment procedure can be performed by selecting Auto
or Manual .
Note: An automatic adjustment fixes most image quality issues. Always perform the
Auto procedure before performing the Manual adjustment.
– Auto : The adjustment is done automatically by the press. It eliminates the need for you to
interpret printed targets and enter adjustment values manually. This saves time and
avoids errors.
– Manual : The user must manually perform the adjustment, including printing test patterns,
interpreting the printed targets on those patterns, and then manually entering the
adjustment values.
Tip: Use the Manual adjustment option only when the Auto adjustment does
not provide the desired output.
– For detailed information and instructions on using the Auto and Manual adjustment
options, refer to Secondary Transfer Voltage Adjustment .
2. If the issue is observed on the tail edge of the printed output and is not corrected by performing a
Secondary Transfer Voltage Adjustment , change the Transfer Output Adjustment for Trail
Edge setting.
• Use this feature to adjust the voltage ratio on the secondary bias transfer roll (2 nd BTR); this is
where the image is transferred from the belt to the paper.
• This feature is accessed from PredictPrint Media Manager → Stock Library → Stock
Properties → Advanced Setup → Transfer Output Adjustment for Trail Edge .
• Decrease the Transfer Output Adjustment for Trail Edge in increments of 10%. After every
incremental adjustment, run test prints and evaluate the output to determine if additional
adjustment is necessary.
3. Perform an Automatic Density Uniformity Adjustment .
Note: This is a press feature and is not a PredictPrint Media Manager feature.
• Use this feature to correct image quality issues on the output when that image quality is not
consistent throughout the entire output. For example, the image quality is lighter or faded or it
is heavier or thicker on the left or right sides of the output, inboard or outboard.
• For information and instructions on how to use this feature, refer to Adjusting Automatic
Density Uniformity .
