Adjusting the Transfer Condition of the Printed Image

If the overall printed image is lighter in color or distorted compared to when printed on regular paper, you can register that paper as a custom paper type and adjust the Secondary Transfer Voltage (voltage when the image is transferred onto the paper). The adjustment results are applied when you specify the paper type and perform printing.
Step 1: Registering the Paper Type
Step 2: Adjusting the Secondary Transfer Voltage
NOTE
When you adjust the transfer condition of the printed image, the print position settings may be affected. Adjusts the print position, as needed. Adjusting the Print Position
