How do I perform paper advance calibration? 6. Look at each of the printed patterns (1 to 7) and decide which one shows the best quality. Each pattern has one part on the left that is a continuous color gradient (A), and another part on the right (B). Either part can be used to help you decide which is the best of the series of patterns; it will depend on your circumstances. However, if you are using glossy paper or canvas, you are recommended to ignore part A and make your selection by looking at part B only. - In the color gradient, part A, you should look for light or dark horizontal bands (banding), which indicate that the paper advance is not quite right. Usually you will see dark bands across the first pattern and light bands across the last pattern (see the examples below). The best pattern is one with no banding; if in doubt, select the pattern in the middle, between the last pattern with dark bands and the first pattern with light bands. 123

Look at each of the printed patterns (1 to 7) and decide which one shows the best
quality. Each pattern has one part on the left that is a continuous color gradient
(A), and another part on the right (B). Either part can be used to help you decide
which is the best of the series of patterns; it will depend on your circumstances.
However, if you are using glossy paper or canvas, you are recommended to
ignore part A and make your selection by looking at part B only.
–
In the color gradient, part A, you should look for light or dark horizontal bands
(banding), which indicate that the paper advance is not quite right. Usually
you will see dark bands across the first pattern and light bands across the
last pattern (see the examples below). The best pattern is one with no
banding; if in doubt, select the pattern in the middle, between the last pattern
with dark bands and the first pattern with light bands.
