HP AIS Certification Exam HP0-714

The new TestKing.com trainee technician wants to know how the bubble jet keeps it
ink jets free from blocking. How will you reply?

A. You must vacuum the dust and debris periodically, or using a can of compressed air to
blow.
B. The maintenance station contains a small suction pump and an ink-absorbing pad.
C. The cleaning blade HP0-460 gently scrapes it clean of any residual toner.
D. None of the above
Answer: B
Explanation:
When the printer is done printing, the print-head moves back to its maintenance station.
The maintenance station contains a small suction pump and ink absorbing pad. To keep
the ink flowing freely, before each print cycle, the maintenance station pulls ink through
the ink nozzles using vacuum suction. This expelled ink is absorbed by the pad in the
maintenance station.

Incorrect Answers:
A: Cleaning a dot-matrix HP0-714 printer is usually a preventative maintenance measure. You
must vacuum the dust and debris periodically, or using a can of compressed air to blow
out dust.
C: After the erase unit returns the EP surface to a neutral charge, a rubber cleaning blade
gently scrapes it clean of any residual toner.
D: This is incorrect HP0-841 since option B represents the answer.
