							12.Remove the soiled sponge from the carriage interconnect wiper.
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.
NOTE:You 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) on page 117.
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.
CAUTION:When 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 on page 168.
NOTE:The 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.
NOTE:The 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.

							NOTE:If 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.
NOTE:Make 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.

							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 on page 108.
●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 on page 108.
●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 on page 108.
●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.
Check printer usage statistics
1.Access the Embedded Web Server (see Access the Embedded Web Server on page 17).
2.Go to the Usage page.
3.Go to the Historical tab to see the accumulated usage of the printer since the first day.
4.Go to the Snapshot tab to save a record of the accumulated usage since the first day, and reset
the Accumulated tabs counters to zero.
5.Go to the Accumulated tab to view the accumulated usage since the last snapshot.
NOTE:The accuracy of these usage statistics is not guaranteed.
Check ink and paper usage for a job
1.Access the Embedded Web Server (see Access the Embedded Web Server on page 17).
2.Go to the Accounting page, which shows you all the information regarding the jobs recently printed
by the printer.
Alternatively, go to the Jobs Queue page, and click on the name of the job on which you want
information. Its properties page will then be displayed.
Request accounting data by E-mail
1.Ensure that the printers date and time have been set correctly. See Set the date and time
on page 19.
2.In the Embedded Web Servers Settings tab, check that the E-mail server has been set correctly.
3.Also in the Settings tab, select Device setup and choose settings in the Accounting section. You
must enter an E-mail address to which accounting files can be sent, and the frequency with which
they will be sent.
4.You may also choose to require an account ID with every print job. In this case, anyone sending
a print job must provide an account ID, otherwise the printer will hold the job in the queue until an
108 Chapter 10   How do I... (accounting topics) ENWW

							ID is provided. You can supply an account ID when submitting a job with the Embedded Web Server
or with a printer driver (using the Accounting tab).
5.When you have completed the above steps, the printer will send accounting data by E-mail with
the frequency that you specified. The data are provided in XML and can easily be interpreted by a
third-party program. The data provided on each job include the job name, the account ID if any,
the user name, when the job was submitted, when the job was printed, the printing time, the type
of image, the number of pages, the number of copies, the paper type and size, the amount of each
color of ink used and various other attributes of the job.
Images are categorized into four types:
●A: Low-coverage lines (less than 0.5 ml/m²)
●B: High-coverage lines (0.5 to 2 ml/m²)
●C: Maps and low-coverage renders (2 to 5 ml/m²)
●D: Photographs (more than 5 ml/m²)
You can download an Excel template from HPs Web site (http://www.hp.com/go/graphic-arts/) that will
enable you to display the XML data more readably in the form of a spreadsheet.
Analysis of the accounting data will enable you to bill customers precisely and flexibly for the use of your
printer. You can, for instance:
●Bill each customer for the total amount of ink and paper used by that customer over a particular
period.
●Bill each customer separately per job.
●Bill each customer separately for each project, broken down by job.
