Moisture
NOTE: This product dissipates heat by using convective
cooling. The heat and moisture generated by the printing
process escape through vents in the product exterior or
through the output bin area.
Water droplets from the convective cooling process will not
damage the product.
Verify normal product operation
The release of moisture is a result of normal product
operation. However, HP recommends using the following
steps to verify that the product is releasing steam and does not
have a functional problem.
1. Turn the product off, and then on.
2. Send a print job to the product, and then verify that the
product is operating correctly.
3. When printing a job and vapor is visible, immediately
reprint the job using the same sheet of paper. There
should be either no visible vapor, or much less vapor
during the printing process.
Limit or reduce steam or vapor
● Make sure that the product is placed in a well-ventilated
area that meets the environmental specifications in this
guide. See
Environmental specifications on page 122 .
● Do not place the product, or store paper, near an
outside entrance where temperature changes can
increase humidity.
● Use an unopened ream of paper that has not been
exposed to high humidity.
● Store paper in an airtight container, where it will be less
likely to absorb moisture.
● Place the product in quiet mode, and send the print job
again. See
Quiet mode settings on page 59 .
