Insert a printhead
1. If the printhead is new:
a. Remove the blue protective cap by pulling down on it.
b. Remove the clear protective tape from the printhead's nozzles by pulling on the paper tab.
The printhead is designed to prevent you from accidentally inserting it into the wrong position.
Check that the colored label on the printhead matches the colored label of the carriage position
into which the printhead is to be inserted.
2. Insert the new printhead into its correct position in the carriage.
CAUTION Insert the printhead slowly and vertically, straight down. It may be damaged
if you insert it too fast, or at an angle, or if you turn it as you insert it.
