							9.Using the same sponge, clean the lower strip of electrical contacts on the printhead (unless the
printhead is new), avoid touching the upper set of electrical contacts.
CAUTIONDo not touch the surface of the printhead containing the nozzles, which are
easily damaged.
10.After waiting a few moments to allow both connectors to dry, replace the printhead into the
printhead carriage. See 
Insert a printhead.

							13.Dispose of the soiled sponge in a safe place to prevent the transfer of ink onto hands and
clothing.
If the front panel continues to display the Reseat or Replace message, replace the printhead or
contact your customer service representative.
Align the printheads
The printer will normally perform printhead alignment whenever printheads are replaced. If there is
no paper loaded when a printhead is replaced, the printer will perform the alignment the next time
you load paper.
NOTEYou can turn off these automatic printhead alignments from the front panel: select the
 icon, then Printer configuration > Auto printhead alignment > Off.
In addition, you should align the printheads if the Image Diagnostics Print indicates an alignment
error. See 
How do I... (Image Diagnostics Print topics).
1.Make sure that you have a roll of opaque paper loaded in the printer; the best results will be
achieved with the type of paper that you normally use for printing. Single sheets of paper, and
transparent materials such as translucent bond, clear film, matte film, tracing paper, and vellum
are not suitable for printhead alignment.
2.To request printhead alignment (if the alignment is not being performed automatically), go to the
front panel, select the 
 icon, and then Printhead management > Align printheads.

							3.If you are close to the beginning of a roll, the front panel will report that the printer may need to
feed up to 3 m (≈ 10 ft) of paper before starting the printhead alignment. This is necessary to
ensure a successful alignment. In this case, you will be given the following options:
●To continue with the printhead alignment, allowing the printer to feed as much paper as
necessary
●To schedule the printhead alignment to be performed later, after you have used a few
meters of paper for printing
●To cancel the printhead alignment
4.If you choose to continue with the printhead alignment, the process will start immediately,
unless an image is currently being printed, in which case the alignment will be done as soon as
the current print job is finished.
The alignment process takes about twelve minutes.
Remove a printhead cleaner
After you have replaced a printhead, the front panel will prompt you to replace the printhead cleaner.
CAUTIONWhen replacing a printhead, always replace the corresponding printhead cleaner.
Leaving the old cleaner in the printer will seriously shorten the new printheads life and
possibly damage the printer. A new printhead cleaner is provided with each new printhead.
When removing a printhead cleaner:
●Be careful not to get ink on your hands. There may be ink on, around, and inside the replaced
printhead cleaner.
●Always handle and store the replaced printhead cleaner upright to avoid spilling any ink.
WARNING!Make sure the printer wheels are locked (the brake lever is pressed down) to
prevent the printer from moving.
1.The printhead cleaners are located in slots underneath the front panel, at the front of the printer.
Press the top of the service station door to release the catch.

							1.Insert each printhead cleaner into the correct color slot location, in the service station, in the
direction indicated by the arrow shown here.
2.When the printhead cleaner has been pushed all the way in, press inwards and downwards as
indicated by the arrow shown here, until it clicks into place.
If you have difficulty, see I cannot insert a printhead cleaner.
NOTEThe front panel will not show the new printhead cleaner until the right-hand door
is closed.
3.When you have inserted the printhead cleaner(s) into the printer, close the door.
NOTEThe printer needs all the ink cartridges, printheads, and printhead cleaners to be
installed before it can continue.
4.If no paper is loaded, the front panel will instruct you to load some.

							Whenever you insert a new printhead and cleaner, the printer will normally perform a printhead
alignment and color calibration. Both are recommended for best print quality. In some cases, you
may decide to postpone printhead alignment until after some further printing has been done.
NOTEIf you prefer to save some time at the expense of print quality, you can turn off these
automatic procedures from the front panel, by selecting the 
 icon, then Printer
configuration > Auto printhead alignment > Off and Printer configuration > Color
calibration > Off.
The front panel may request that you load paper that is suitable for printhead alignment. The
printhead alignment procedure requires a roll of opaque paper: not a single sheet, and not any kind
of transparent or translucent material.
When the front panel displays Ready, you are ready to print.
NOTEMake sure the printer window and the right-hand door are closed after you replace
the supplies. The printer will not print while these are open.
Check the status of the ink system
1.Access the Embedded Web Server (see Access the Embedded Web Server).
2.Go to the Supplies page.
The Supplies page shows you the status of the ink cartridges (including the ink levels), the
printheads, the printhead cleaners, and the loaded paper.

							Get accounting information from the printer
There are various different ways of getting accounting information from your printer.
●View printer usage statistics for the whole lifetime of the printer, or for particular periods. See
Check printer usage statistics.
●View ink and paper usage for each of your recent jobs by using the Embedded Web Server or
the printers front panel. See 
Check ink and paper usage for a job.
●Request accounting data by E-mail. The printer sends data in XML at regular intervals to a
specified E-mail address; the data may be interpreted and summarized by a third-party
application, or displayed as an Excel spreadsheet. See 
Request accounting data by E-mail.
●Use a third-party application to request printer status, printer usage, or job accounting data from
the printer through the Internet. The printer provides data in XML to the application whenever
requested. HP provides a Software Development Kit to facilitate the development of such
applications.
