6Safety ENWW
Note Only qualified service personnel should disable relay functions and safety functions
when it is necessary to solve problems.
Checkpoints when performing on-site service
HP MFPs are extensively tested before shipping to ensure that all applicable safety standards
are met, and to protect the customer and customer engineer (hereafter called the CE) from the
risk of injury. However, in daily use, any electrical equipment may be subject to parts wear and
eventual failure. In order to maintain safety and reliability, the CE must perform regular safety
checks.
● Do not disable relay functions (such as wedging
paper between relay contacts).
● Do not disable safety functions (interlocks, safety
circuits, and so forth). Safety will not be assured,
leading to a risk of fire and injury.
● Do not make any modification to the MFP unless
instructed by HP.
● Do not use parts not specified by HP.
