2.
they go back in the same order
1. Cyan cartridge
3. Yellow cartridge
Lift each of the image drum units, starting from the rear, out of

the printer and place them in a safe place away from direct
sources of heat and light.
The green image drum surface at the base of each cartridge is very
delicate and light sensitive. Do not touch it and do not expose it to
normal room light for more than 5 minutes. If the drum unit needs to be
out of the printer for longer than this, please wrap the cartridge inside
a black plastic bag to keep it away from light. Never expose the drum
to direct sunlight or very bright room lighting.
