3 Remove one of the photodevelopers from its packing material.
You can install the photodevelopers in any order. However, it may be easier to install them from left to right: black, yellow, cyan, and magenta.
4 Remove the tape from the photodeveloper.
The photodeveloper has a cover over the green glass tube. Do not touch the glass. Touching the glass may damage it and reduce print quality. Do not remove the cover until you begin installing the photodeveloper.
5 Align the photodeveloper with the slot in the printer as shown.
