Chapter 6: Shutdown and Maintenance 211
Cleaning the Camera Windows
• Clean the lower camera window and the diode laser window when you
have trouble viewing the side streams or you cannot set the drop delay
using Accudrop. Wipe the windows with a soft, lint-free cloth soaked with
DI water, and then dry the windows.
• Clean the strobe lens and upper camera window when smudges appear in
the processed (digitized) image in the Breakoff window, or when dark spots
appear to interfere with Sweet Spot monitoring. You might need to clean
these components after a clog, or after sheath fluid has leaked or sprayed.
Follow the steps in this section to clean the strobe lens and upper camera
window.
Before you begin this procedure, block the lasers, turn off the stream, and ensure
that the deflection plates are not charged (warning light is not illuminated).
A 12,000-volt potential exists between the deflection plates when they are
on. Contact with the charged plates results in serious electrical shock. Do
not touch the deflection plates when the plate voltage is on. The plates
remain energized even when the sort block door is opened.
