Running the Self Test

The self test can be run in the draft or Letter Quality mode,
depending on which button you hold down as you turn on the
printer. Although the self test can be run with continuous paper, use
single-sheet paper now because single-sheet loading is easier.
1. Make sure the printer is turned off.
2. Push the paper release lever back to the single-sheet position.
