17. Using the stops, carefully wind the excess paper back onto the spindle.
18. The printer will automatically perform printhead alignment and a color calibration
for the paper type that you have loaded. During this process the printer will
advance the paper by up to 3 m (≈10 ft) before printing. Please do not try to stop
the paper advance; it is necessary to ensure a successful printhead alignment.
The whole alignment and calibration process will take about twenty minutes;
while it is going on, you can start connecting the printer. See “How do I connect
the printer?” on page 56.
