changed, takes about 18 minutes. If the printer identifies a problem when preparing the
printheads, the process takes longer, up to 30 minutes. For a single printhead insertion, the time
varies between 10 and 20 minutes. After all printheads are checked and prepared, the printhead
realignment procedure runs automatically if paper is loaded. See Align the printheads
on page 71 .
Clean (recover) the printheads
To clean the printheads (which often enables them to recover from problems), go to the printer's front
panel and select the
icon, then select Clean printheads. Specify which printheads you would
like to clean. You can clean all of the printheads or only some of them.
Cleaning all printheads takes about 5 minutes. Cleaning any two printheads takes about 3 minutes.
NOTE: Cleaning all printheads uses more ink than cleaning a single pair.
NOTE: HP recommends that you purge the ink from the printheads before printing a job if the printer
has been turned off for more than six weeks or if you are experiencing inconsistent colors from print to
print after long storage periods. Purging the ink from the printheads helps to ensure maximum color
consistency; it is not a remedy for poor printhead health.
Clean the electrical connections on a printhead
It is possible that the printer will not recognize a printhead after it has been installed. This can happen
when ink builds up on the electrical connections between the printhead and the printhead carriage.
Under these circumstances, HP recommends that you clean the electrical connections on the printhead.
However, routine cleaning of the connections when no problems are apparent is not recommended.
Use an absorbent lint-free cloth, slightly dampened with isopropyl alcohol, to clean the electrical
interconnects on both the printhead carriage and the printhead if the Reseat or Replace message
persists next to the printhead on the front-panel display.
1. Open the printhead carriage latch and extract the printhead that is causing the problem, as
indicated on the front panel. See Remove a printhead on page 63 .
2. Cover your finger with the cloth and insert it into the printhead slot at the back.
CAUTION: If the carriage remains in the central part of the printer for more than 7 minutes, it
attempts to return to its home position to the right.
