Theory of Operation
Transfix roller oiling

Drum cleaning (chase page)

5-32 Phaser 360 Color Printer
At the first opportunity after making 50 prints when no prints are queued and
the printer is idle, the printer performs a transfix roller oiling cycle. During this
cycle, oil is applied to the drum as it would be during a print cycle. Then the
transfix roller is lowered against the drum and the drum rotates; this transfers
the oil to the transfix roller, then the transfix roller is raised to its standby
position.
The printer performs a drum cleaning with a chase page automatically anytime
a paper jam occurs after an image has been "printed" on the drum. The chase
page transfers the image, which may not be complete, off the drum and is
usually discarded. The printer then attempts to reprint the print that jammed.
The chase page is processed the same as a regular print except the drum is not
oiled and no image is printed on the drum (since an image is already printed on
the drum).
