Ghosting (2)
There is ghosting at 75.3 mm intervals when printing on card stock or 
transparencies using the manual feeder. When printing on thicker media or 
transparencies, a higher transfer voltage is required. Setting the Paper Type to 
Thick provides a higher voltage level to the Print Cartridge.
Initial Actions
• Check that the Paper Type is set to Thick in the printer driver.
• Verify the paper is within the printer specifications (refer to “Media and Tray 
Specifications” on page 1-16).
