ABSTRACT:
A printing apparatus includes one or more recording components which are operative upon a recording member for use in recording an image upon the recording member. The recording member is moved in a process path during recording and operated upon by the one or more recording components used in recording. An access door cover is openable for providing access to a serviceperson to the one or more recording components and/or the recording member. A blower establishes an air path of air within the apparatus to control temperature and humidity of the recording components. The air path has a substantial current flowing in a direction transverse to the process path and over or about the recording member and/or the one or more recording components towards the access door cover. The blower, upon opening of the access door cover, establishes a substantial airflow path of air from directly outside the access door cover into the apparatus so as to reduce flow of contaminated air from the apparatus towards the serviceperson.
