Step Questions and Actions
1 1. On the Control Panel, select the Eliminate
Light Stripes function and follow the

2 1. It may be necessary to repeat Step 1
up to 3 times if the stripes still appear.
NOTE: If there are discolored jets, print the
solid fill test print in the color with the
discolored jets. In the following
example, the yellow stripe has
discolored jets, therefore you would
print the yellow solid fill. For
instructions on printing solid fill test
prints, see "Black, Red, Green, Blue,
Cyan, Magenta, and Yellow Solid
Fills" on page 5-40.
Discolored jets usually clear after two or
three prints, using the problem jets.
