A Before and after installation

Acclimate the printer before installation

Open the printer's doors, drawers, and covers. Leave the printer in the installation area until there is no visible
condensation before proceeding with the installation.
It may be necessary to allow the printer, agent cartridges, and accessories to adjust to temperature change
before installation if they have been subjected to extended periods of cold or heat during storage or
transportation.
Exposure to extended periods of heat usually requires a minimal amount of acclimation time.
Exposure to extended periods of cold can cause condensation in the devices when they are moved into warmer
areas. Condensation on the printer indicates the need for an acclimation period until the condensation
disappears.
Exposure to extended cold below 0°C (32°F) can cause the agent cartridges and printhead(s) to freeze. The agent
cartridges and printhead(s) are designed to be exposed to freezing temperatures without being damaged.
However, if the material is frozen and cannot flow properly during printing, the printhead(s) will be starved of
fluid, which will destroy the printhead(s).
CAUTION:
if these items do need to be acclimated. Acclimation will not damage these items, but the failure to acclimate can
cause issues or severe damage to the printhead(s).

Acclimate the agent cartridges and printheads

Unpack the agent cartridges and printheads first. It is important to remove the agent cartridges and printheads
from their packaging. Packaging acts as an insulation barrier and will prevent any frozen agent from thawing
quickly.
Agent cartridges and printheads may need up to 24 hours to acclimate to operating temperature, depending on
previous and current temperatures.
Moving the agent cartridges and printheads into a warmer area can accelerate the thawing.
CAUTION:
condensation by carefully blotting the electrical connections with a lint-free cloth. Do not wipe or drag the cloth
across the connections, to avoid damaging them.

Recycle the consumables

HP provides many free and convenient ways to recycle your used HP lamps, cartridges, and other consumables;
see https://hp.com/recycle/. Where this program is not available, dispose of the consumables according to local
