7. Close the window.
8. The front-panel display conrms that all printheads are correctly inserted. The printer starts checking and
preparing the printheads. The default routine process, when all printheads are changed, takes 10 minutes.
If the printer nds problems in preparing the printheads, it takes longer, up to 45 minutes. For a single
printhead insertion, the times vary between 2 and 45 minutes. After all printheads are checked and
prepared, the printhead realignment procedure runs automatically if paper is loaded, see Align the
printheads on page 183.
9. You are recommended to perform a color calibration after inserting a new printhead. See Color calibration
on page 88.
Safe mode
Under certain conditions, including printer operation outside of environmental specications, and when a used,
relled, or counterfeit ink cartridge has been detected, the printer will operate in safe mode. HP is unable to
warrant the performance of the printing system when operated outside of environmental specications or when
a used, relled, or counterfeit ink cartridge is installed. Safe mode is designed to protect the printer and the
printheads from damage due to unexpected conditions, and is in operation when the icon is displayed on the
printer’s front panel and by the Embedded Web Server and HP Utility.
For optimal performance, use original HP ink cartridges. HP DesignJet printing systems, including original HP inks
and printheads, are designed and engineered together to provide uncompromising print quality, consistency,
performance, durability, and value—with every print.
NOTE: This printer is not designed to use continuous ink systems. To resume printing, remove the continuous
ink system and install genuine HP (or compatible) cartridges.
NOTE: This printer is designed for ink cartridges to be used until they are empty. Relling cartridges prior to
depletion might cause your printer to fail. If this happens, insert a new cartridge (either genuine HP or
compatible) to continue printing.
NOTE: Dynamic security enabled printer. Only intended to be used with cartridges using an HP original chip.
Cartridges using a non-HP chip may not work, and those that work today may not work in the future. More at:
