Maintenance Tray; Figure 5-4 The Drum Maintenance Tray - Tektronix Phaser 360 Service Manual

Maintenance tray

The maintenance tray performs two functions. Its primary function is to create a
thin intermediate liquid transfer surface, a layer of silicone oil, on the surface of
the drum prior to printing. The oil keeps the ink from sticking to the drum's
surface and facilitates its transfer to the sheet of paper or transparency film. The
oil is contained in a 100 cc bladder. Oil is applied to the drum using an
oil-saturated wick supplied by two tubes from the bladder. Small valves keep
the oil from leaking out of the bladder when the maintenance tray is not in the
printer. The drum maintenance tray's second function is to collect waste ink
from printhead purges in a waste bin.
Note
The oil valves are always open when the maintenance tray is installed
in the printer. The oil can leak if the printer does not remain level.
