HP AIS Certification Exam HP0-795

Which of the following statements is TRUE?

A. The AC/DC powers up the printer to a 1,000 volts in relation to the +5 and +24Vdc of
the HVPS.
B. High-voltage power supply HP0-754 produces 1,000 volts or more needed to create a
static-electricity charge.
C. If you didn't drain away the charge, the paper would stick to the EP cartridge and
anyone operating it would get an electrical shock.
D. None of the above

Explanation:
The high-voltage power supply produces 1,000 volts or more needed to create a
static-electricity charge, HP0-755 which pulls toner particles into position.

Incorrect Answers:
A: The DC power supply converts AC from the main power supply to the voltages
typically used on an integrated circuit board, which is about +5 and +24 Vdc.
C: In the corona assembly is a static-charge eliminator strip that drains away the charge
imparted to the paper by the corona. If you didn't drain away the charge, the paper would
stick to the EP cartridge and jam the printer.
D: This is incorrect HP0-795 since HVPS is capable of producing 1,000 volt or more charges when
necessary as option B suggests.
