Operation
Functional Checkout
The Functional Checkout procedure is to help you confirm that your GenePix
Professional 4200A microarray scanner is performing according the specifications
set by Axon Instruments, Inc. A similar, but much more detailed procedure was
performed at the factory prior to shipping this unit to you. We recommend that you
follow the procedure once upon receiving the instrument and then any time after
that if you wish to check the performance of the instrument.
The GenePix 4200A microarray scanner has been designed to provide robust, long-
lived microarray scanning for years of normal use. However, if the images you
acquire on the GenePix scanner do not appear correct and if you believe there is a
problem with the scanner, it is important to follow these instructions before
contacting Technical Support:
1. Start the GenePix Pro software and click the Report tab.
2. Click the Functional Checkout link.
3. Follow the Functional Checkout procedure.
GenePix Pro automatically logs hardware performance into the Hardware
Diagnostics Report every two hours during operation.
Installing Additional Filters
Your GenePix 4200A Professional scanner comes with one standard filter for each
installed laser. The standard filters are not accessible by the user. You can install
additional filters in any of the twelve remaining filter positions.
The installation process involves two steps:
1. Install the filters in the scanner;
2. Record the information for the new filters in GenePix Pro.
