							6. Insert the carriage interconnect wiper into the printhead slot at the 
back. Wipe the electrical contacts
by inserting the tool between the electrical connectio ns at the back of the slot and the steel spring,
with the sponge facing away from you and toward s the electrical contacts. Try to avoid picking up
any ink deposit that may have accumula ted on the bottom surface of the slot.
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.
7 . Rub the sponge against the contacts with a 
light force along the entire depth of the flex connector,
inserting the wiper as far as allowed  by the mechanical stop on the tool.
8. Take special care to clean all contacts thoroughly
, including the ones at the lowest point of the
connector.

							9. Using the same sponge, clean the lower strip of el
ectrical contacts on the printhead (unless the
printhead is new). Avoid touching th e upper set of electrical contacts.
CAUTION:Do not touch the surface of the printh ead that contains the nozzles, because
the nozzles are easily damaged.
10. After waiting a few moments 
to allow both connectors to dry, repl ace the printhead into the printhead
carriage. See 
Insert a printhead on page 64 .
11. After completing the cleaning process, open the ca

							If the front panel continues to show the Reseat or Replace  message, replace the printhead or contact
your HP customer service representative.
Align the printheads
The printer performs printhead alignment whenever pr intheads are replaced. If no paper is loaded when
a printhead is replaced, the printer will perf orm the alignment the next time you load paper.
Also align the printheads if the Printhead st atus plot indicates an alignment error. See 
Use the Printhead
status plot on page 71.
1 . Make sure that you have a roll of opaque, white p
aper loaded in the printer. Colored papers, glossy
canvas, and transparent materials such as transl ucent bond, clear 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 select  Image quality maintenance >  Align
printheads .
The process takes about 10 minutes and starts i mmediately, unless an image is currently being
printed. If a print job is in process, the alignment  will be done as soon as the current print job is
finished.
NOTE: Occasionally, if the paper in the printer is very close to the beginning of a roll, the
front panel might report that the printer needs to feed up to 3 m ( ≈ 10 ft) of paper before
starting the printhead alignment. This is necessary to ensure a successful alignment. You can
continue with the printhead alignment and allow the printer to feed as much paper as
necessary, delay the alignment until later, or cancel the alignment.
Use the Printhead status plot
The Printhead status plot co nsists of patterns that are designed to  highlight printhead-reliability problems.
It helps you to check the performance of the printheads that are currently installed in your printer, and to
determine whether any printhead is expe riencing clogging or other problems.
Print the Printhead status plot
To print the Printhead status plot:
1. Use the same paper type that you were
 using when you detected a problem.
2 . Verify that the selected paper type is the same 
as the paper type that is loaded into the printer.
3 .
On the printers front panel, select the 
 icon, and then select  Image quality maintenance
>  Printhead diagnostics image .
It takes about 2 minutes to print the Printhead status plot.

							Interpret the Printhead status plot
The print is divided into two parts, bo th of which test printhead performance.
● Part 1 (top) consists of rectangles
 of pure colors, one for each printhead. This part represents the
print quality that you will get from each color.
● Part 2 (bottom) consists of small dashes, one 
for each nozzle on each printhead. This part
complements the first, and detects how many faulty nozzles are on each printhead.
First look at the top part of the print. Each colo red rectangle should be a uniform color without any
horizontal lines across it.
Then look at the bottom part of the print. For each in dividual colored pattern, make sure that most of the
dashes are present.
If you see horizontal lines in the top part and also  see missing dashes in the bottom part for the same
color, the printhead for that color needs to be cleaned.  However, if the rectangles look solid, do not worry
about a few missing dashes in the bottom part, beca use the printer can compensate for a few clogged
nozzles.
The graphic shown illustrates printhead 2 in a bad state:

							Corrective action
1. Clean any faulty printheads. See Clean the printheads on page 168
. Then reprint the Printhead
status plot to see whether the problem has been solved.
2 . If the problem persists, clean the printheads again, 
and reprint the Printhead status plot to see whether
the problem has been solved.
3 . If the problem persists, consider clea
ning your printheads manually. See 
Clean the printheads
on page 168. Also try reprinting your current print jo b, in case it now prints satisfactorily.
4 . If the problem continues to persist, repl
ace any persistently faulty printheads. See 
Work with ink
system components on page 59.
What to do if problems persist
If you still experience print-quality problems after applying the advi ce in this chapter, here are some
additional tips to consider:
● Try using a higher print-quality option. See 
Select print quality on page 80
.
● Check the driver you are using to print with. If it 
is a non-HP driver, consult the driver vendor about
the problem. You could also try using the correct HP  driver, if that workaround is acceptable to you.
Download the latest HP drivers from 
http://www.hp.com/go/designjet/ .
● If you are using a non-HP raster image processing
 (RIP), its settings might be incorrect. See the
documentation that came with the RIP.
● Verify that your printer fi
rmware is up to date. See 
Update the printer firmware on page 141.
● Verify that you have the correct 
settings in your software program.
● Contact HP Support. See 
HP Customer Care on page 183
.
Remove the maintenance cartridge
A message appears on the front panel when you must  change the maintenance cartridge. Follow these
precautions when removing  a maintenance cartridge:
● Be careful not to get ink on your hands. Ink might be on, around, an
d inside the replaced maintenance
cartridge.
● Always handle and store the replaced maintenanc
e cartridge upright to avoid spilling any ink.
CAUTION:A message appears on the front panel when  the maintenance cartridge is almost full
and again when it is completely full and must be changed. You can ignore the alert and continue
printing by pressing the OK button on the fron t panel. However, HP strongly recommends that you
change the maintenance cartridge when prompted.  Ignoring the alert can result in serious damage
to the printer.
