Sensitive consumable components of printing devices involved in the process
of transferring and fixing an image with toner onto a print medium are protected
from harmful exposure to the environment and handling through designating and consistently
positioning non-use regions of the components toward exposure gaps in their protective
housings upon the completion of every printing process. The need for shutter mechanisms
on consumable housings to cover up exposure gaps to protect consumables while in
a general handling environment is therefore reduced.
