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 as the texture
of an orange peel. For blistering to occur, it must appear on the second side of the
second of two or more solid-fill duplex prints. Before enabling Duplex Oil Chase,
try different, heavier paper. Duplex Oil Chase enabled causes a blank page to
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

from the drum that might otherwise appear on a print.
