							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 automa tically 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 printers 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. Cl eaning 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 pr intheads 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 fr om the printheads helps to ensure maximum color
consistency; it is not  a remedy for poor printhead health.
Clean the electrical conn ections on a printhead
It is possible that the printer will not recognize a pr inthead 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 printhea d on the front-panel display.
1. Open the printhead carriage latch and extract th
e 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.

							3.Rub the cloth against the electrical contacts with a 
light force along the entire depth of the flex
connector. Try to avoid picking  up any ink deposit that may have accumulated on the bottom
surface of the slot.
4. Take special care to clean all contacts thoroughly
, including the ones at the lowest point of the
connector.
5. Using the same cloth, clean the strip of electrical
 contacts on the printhead (unless the printhead is
new). Avoid touching the printhead nozzles.
CAUTION: Do not touch the surface of the printhead  that contains the nozzles, because the
nozzles are easily damaged.
6. After waiting a few moments to 
allow both connectors to dry, replace the printhead into the
printhead carriage. See 
Insert a printhead on page 66.
7. Wash or dispose of the cloth. Take care to prevent the transfer of ink onto hands and clothing.
If the front panel continues to show the Reseat  or Replace  message, replace the printhead or contact
your HP customer service representative.
Clean the printhead drop detector
The printhead drop detector is a se nsor that detects which nozzles on the printheads are not printing,
so that other nozzles can substitute  for them. If particles block the sensor (such as fibers, hair or small
pieces of paper), print quality is affected.
When the front panel displays a warning message that the drop detector needs cleaning, you are
recommended to clean it. If you do  not clean it immediately, the printer continues working normally, but
the front panel display cont inues to show the warning.
CAUTION:Wear gloves to avoid getting ink on your hands.

Align the printheads
Precise alignment between printheads is essential 
for accurate colors, smooth color transitions and
sharp edges in graphical elements. Your printer ha s an automatic printhead alignment process which
runs whenever a printhead has been accessed or replaced.
If the paper has jammed or you are  experiencing problems with color accuracy, you may need to align
the printheads.
NOTE: If the paper has jammed, it is recommended that  you reinsert the printheads and initiate the
realignment procedure from the  Image Quality Maintenance menu 
.
CAUTION:Do not use transparent or semi-trans parent paper to align the printheads.
Reinsert printheads procedure
1.If the realignment process is running an
d the wrong paper is loaded, press the  Cancel key on the
front panel.
CAUTION: Do not print if the realignment process  has been canceled. You can restart the
alignment with the Image Quality Maintenance menu procedure.
2. Load the paper you wish to use, see Handle the paper on page 29
. You can use a roll or cut
sheet, however, it must be A3 landscape or larger.
CAUTION: Do not use transparent or semi-transpa rent paper to align the printheads.

							3.Remove and re-insert a
ll the printheads, see Remove a printhead on page 63 and Insert a
printhead on page 66. This starts the printhead alignment procedure.
4. Ensure the window is closed, as a strong li
ght source near the printer during printhead
realignment can affect alignment.
5. The process takes about six minute
s. Wait until the front-panel display shows the process complete
before using the printer.
NOTE: The printer prints a calibration image. Do not worry about the image. The front-panel
display shows any errors in the process.
Image Quality Maintena nce menu procedure
1.Load the paper you wish to use, see Handle the paper on page 29
. You can use a roll or cut
sheet, which must be A3 landscape or larger: 420 × 297 mm (16.54 × 11.69 in).
CAUTION: Do not use transparent or semi-transpa rent paper to align the printheads.
2.
From the front panel, select the Im age Quality Maintenance menu icon , then Align
printheads. The printer checks to see if it has enough paper to run the realignment.
3. If the loaded paper is satisfactory, the printer 
runs the realignment and prints a realignment
pattern. Ensure the window is closed, as a strong  light source near the printer during printhead
realignment can affect alignment.
4. The process takes about five mi
nutes. Wait until the front-panel display shows the process
complete before using the printer.
Scanning errors during alignment
If the alignment process fails, a Scanning problems message appears on the front panel. This means
that the alignment has not complete d successfully. Therefore the printer is not aligned and the alignment
should be repeated before printing with go od image quality. The problem may be due to:
● The paper used was not valid, repeat the alignment with valid paper
● Printhead health problems, clean printheads, see 
Clean the printheads on page 165
● The alignment was done with the window open, 
repeat the alignment with the window closed
If the problem persists after using valid paper, clea ning the printheads and keeping the window closed,
there may be a failure in the scanning system need ing reparation or the printheads, although clean,
may not work and need  to be replaced.
The Image Diagnostics Print
The Image Diagnostics Print consists of patterns desi gned to highlight printhead reliability problems. It
helps you to check the performance of the printheads  that are currently installed in your printer, and
whether any printhead suffers from clogging or other problems.
