Maintenance . 97
Inspecting the Imager
At least once a year, or whenever the imager has been subjected to adverse environmental
conditions, visually inspect the housing to make sure that no covers are loose or distorted.
At the same time, make sure that all required labels are firmly in place (see Figures 2–5 on
pages 19–20).
Protecting the Imager
The most important rule in caring for the imager is to keep it as free from dust and dirt as
possible. Dust, fingerprints, and smears on the optics reduce the quality of the images it
produces.
Whenever the imager is not in use, cover it with its plastic cover.
CAUTION
Ensure the power is switched off when the imager is covered.
Cleaning the Optics
The imager was aligned, cleaned, and sealed at the factory. Do not attempt to take it apart.
CAUTION
Avoid the excessive use of solvents. Flowing solvents dissolve the cement
on cemented optics; dissolved cement can damage mirror surfaces.
Cleaning the Cover
CAUTION
Ensure the power is switched off and the supply lead is disconnected
before cleaning the cover.
You can clean the outside of the imager or stage controller using a damp cloth. Mild
detergent may be used, if necessary. Always perform a patch test on an inconspicuous area
before you clean the entire instrument.
Avoid spilling liquid into the imager or stage controller. Clean all external spills immediately.
If anything that is spilled enters the main body of any part of the system, switch off the
power and call a PerkinElmer Service Engineer.
