Selecting Duplex (2-sided) Oil Chase

This item is turned on to correct a print artifact called "blistering." Blistering, when it
occurs, affects the duplexed side of a solid fill and appears similar to the texture of an
orange peel. For blistering to occur, it appears on the second side of the second of two or
more solid-fill duplex prints. Before enabling Duplex Oil Chase, try different, heavier
paper. With Duplex Oil Chase enabled, a blank page will print on simplex to duplex
printing transitions and after every 50 duplex prints.

Selecting Envelope Oil Chase

When this menu item is turned enabled, the printer will process a blank sheet of paper
through the printer when ever the printer is switched from printing envelopes to printing
on paper or transparency film. This removes ink artifacts from the drum that might
otherwise appear on a print.
