Only replace one component at a time and

check if the problem has gone before

replacing another component. Using this

procedure you will be able to determine

exactly which component failed.

Test Pattern 5: Color Variation Test

This test produces four boxes; black, blue, cyan and yellow. In each box

there are three horizontal bands, the two outer bands are 100% shade, the

inner band is shaded from 100% scaling to 75%.

The purpose of this test is to determine at what percent the middle shading

becomes visible from the two outer bands. The best way to do this is to cover

the box with a piece of paper and slide the paper horizontally across the box.

Stop as soon as you see a different shade in the middle box. You can then

determine the percentage scaling from the figure at the top of the box.
