10 Chapter 1 Introduction ENWW
Turn the printer on and off
To turn on the printer, ensure that the residual current circuit breakers are in the up position and the power
switch at the rear of the printer is turned on. If the printer does not start automatically, press the Power
button on the front panel.
You can leave the printer on without wasting energy. Leaving it on improves response time. When the printer
has not been used for a certain period of time, it saves power by going into sleep mode. Any interaction with
the printer returns it to active mode, and it can resume printing immediately.
If you want to turn the printer on or off, the normal and recommended method is to use the Power button on
the front panel.
When you turn off the printer this way, the printheads are automatically stored with the printhead cleaning
cartridge, which prevents them from drying out.
However, if you plan to leave the printer turned off for a long period of time, you are recommended to turn it
off using the Power button, and then also turn off the power switch at the rear.
To turn it back on later, use the power switch at the rear. If the printer does not start automatically, press the
Power button on the front panel.
When the printer is turned on, it takes about 5 minutes to initialize itself.
Restart the printer
In some circumstances you may be advised to restart the printer. To do so, press the Power button on the
front panel to turn the printer off. Wait a few moments, then press the Power button again. This should
restart the printer.
If the printer fails to restart, try the following alternative procedure.
ENWW Turn the printer on and off 11
1. Turn off the printer by using the power switch at the rear of the printer. Check that the residual current
circuit breakers are in the up position.
2. Wait for 10 seconds.
3. Turn on the printer by using the power switch.
4. Make sure that the Power light on the front panel illuminates. If it does not, use the Power button to
turn on the printer.

2 Connectivity and software instructions
Connection method
Your printer can be connected in the following way.
Connection type Speed Maximum cable length Other factors
Gigabit Ethernet Fast; varies according to
NOTE: The speed of any network connection depends on all the components that are used in the network,
which can include network interface cards, hubs, routers, switches, and cables. If any one of these
components cannot operate at high speed, you will have a low-speed connection. The speed of your network
connection can also be affected by the total amount of traffic from other devices on the network.
Connect to a network
Before you begin, check your equipment:
●
The printer should be set up and turned on.
●
The Gigabit switch or router should be on and functioning correctly.
●
All computers on the network should be turned on and connected to the network.
●
The printer should be connected to the switch.
When the printer is connected to the network and turned on, you should see the printer's IP address appear
on the front panel (12.34.12.34 in this example). Make a note of the IP address: you can use it later to access
the Embedded Web Server.

4 Handle the substrate
Overview
You can print on a wide variety of printing materials, all of which are referred to in this guide as substrates.
Substrate tips
Choosing the correct substrate for your needs is an essential step in ensuring good print quality.
Here are some tips about substrate usage.
●
Allow all substrates to adapt to room conditions, out of the packaging, for 24 hours before using them
for printing.
●
Handle film and photo substrates by the edges, or wear cotton gloves. Skin oils can be transferred to
the substrate, leaving fingerprint marks.
●
Keep the substrate tightly wound on the roll throughout the loading and unloading procedures. To
make sure that the roll stays tightly wound, consider using tape to stick the leading edge of the roll to
the core just before removing the roll from the printer. You can keep the roll taped during storage. If the
roll starts to unwind, it can become difficult to handle.
NOTE: The use of tape to stick the leading edge of the roll to the core is especially important for heavy
substrates, because the inherent stiffness of the substrate can cause it to loosen and unwind from the
core.
●
Using the take-up reel with some substrates, such as textiles, may give the printer better control of the
substrate and is likely to improve print quality.
●
Print quality could be impaired if you use a substrate that is unsuitable for your image.
●
Make sure that the appropriate print-quality setting is selected in the RIP.
●
Whenever you load a roll, the front panel prompts you to specify the substrate family that you are
loading. For good print quality, it is essential to specify this correctly. Check that the substrate belongs
to the family named on the front panel, and check also that it matches the substrate profile in the RIP.
●
If the substrate family shown on the front panel does not correspond to the substrate that you have
loaded, take one of the following actions:
◦
Reload the roll into the printer and select the correct substrate family. See
printer on page 35 and Load a roll into the printer (automatically) on page 28.
◦
At the printer's front panel, press
, then , then Substrate > Change loaded substrate.
Unload a roll from the

For more substrate tips, see
the printer (manually) on page 31.
CAUTION: Removing the substrate from the printer manually without using the front panel could damage
the printer. Do this only when necessary to clear a substrate jam.

9. Remove the strip of self-adhesive vinyl from the platen.
10. Look at the self-adhesive vinyl you have taken from the platen.
●
If the strip is completely white (has no ink on it), the tested substrate is non-porous and can be
used for printing as described in this guide.
●
If the strip is significantly non-white (as in the above example), the tested substrate is porous and
should not be used with this printer.
●
If the strip is lighter in color than PANTONE 427C, the tested substrate may be used for short print
runs.
NOTE: Printing on porous substrates can cause a decrease in print quality that would require a service
repair not covered by your warranty.

For instructions on how to use the take-up reel, see The take-up reel on page 35.
Load a roll into the printer (manually)
The manual loading process should be used in the following cases:
●
The substrate is unusually thin or unusually thick.
●
The substrate has ragged edges.
●
The substrate tends to curl at the edges.
●
The printing side of the substrate faces outwards.
In other cases, the automatic loading process is recommended: see
(automatically) on page 28.
To start this procedure, you need to have a roll loaded on the spindle. See
on page 25.

substrate through.
WARNING! Do not touch the printer's drying enclosure. Even after you have opened the window latch,
which disconnects the power to the drying and curing modules, the internal surfaces could be hot.
TIP: If the substrate you are using tends to curl, keep feeding the substrate until the edge is out of the
printer. You are also recommended to use the take-up reel, or to disable the cutter from the front panel
if not using the take-up reel.
32 Chapter 4 Handle the substrate ENWW
5. Pull down the substrate-adjustment lever as far as it will go.
6. Select the type of substrate you are loading.
NOTE: You should select the name of the particular substrate that you are using in your RIP software,
not in the front panel.
TIP: When loading very thin substrates, always select the substrate type as Banner to minimize the
vacuum pressure applied while loading; when loading very thick substrates, always select the substrate
type as HP Photorealistic to maximize the vacuum pressure. After loading and before printing, go to
the front panel and change to the correct type for the substrate you are loading: press
, then ,
then Substrate > Change loaded substrate.
TIP: When manually loading textile substrates that you intend to use with the take-up reel, before
selecting the substrate type it is a good idea to use the Move substrate option in theSubstrate menu to
advance the substrate beyond the point where it may jam in the printer. This avoids the possibility of a
substrate jam at this stage and also some other substrate issues; and it enables you to skip the normal
check for skew.
7. The printer checks the substrate in various ways and may ask you to correct problems with skew or
tension.
NOTE: You can specify the maximum permitted amount of skew at the front panel: press , then

Load a cut sheet into the printer
The printer is designed to be used with rolls of substrate. It is possible to load cut sheets into the printer, but
print quality cannot be guaranteed, and you may have some difficulty in avoiding skew.
●
The sheet should be at least 1067 mm (42 in) long.
●
Load the sheet by following the normal roll loading process (automatic or manual, depending on the
substrate).
●
During the loading process, the printer tries to detect the winding direction of the roll by turning the
spindle in both directions. When the substrate is not attached to the spindle, the following message
appears.
●
A cut sheet is likely to be loaded with excessive skew, and the printer may not be able to correct it
automatically. If the skew as measured by the printer exceeds 3 mm/m, you are recommended to stop

36 Chapter 4 Handle the substrate ENWW
, then , then Substrate > Enable take-up reel.
2. The front panel offers you the choice of loading the take-up reel immediately, or during printing.
If you decide to load the take-up reel during printing, familiarize yourself with the procedural steps.
Loading the take-up reel during printing requires you to complete the procedure while the printer is
feeding and printing substrate. Loading the take-up reel during printing saves approximately 1.5 m (4.9
ft) of substrate.
TIP: If you have already loaded the take-up reel, but the printer fails to recognize that it is loaded, you
can save some time by selecting Load it during printing.
TIP: You are recommended to keep the take-up reel winding-direction switch in the off position (see
Unload a roll from the take-up reel on page 42) to avoid unwanted movements when loading the
take-up reel while printing. Once you have the leading edge of the substrate attached to the core, and
the substrate is straight, switch the winding-direction switch to position 1 or 2, as you prefer. Setting 1
winds the substrate so that the printed image faces in, setting 2 winds the substrate so that the printed
image faces out.
The following steps assume that you have decided to load immediately. If you decide to load later,
during printing, you must complete the same operations without guidance from the front panel.
3. Ensure that the tension bar is in its raised position (up).

The edge holders
The edge holders are designed to prevent the edges of the substrate from rising while printing is in progress.
They are recommended for textile and double-sided printing (even if the front panel does not suggest them),
and are not normally necessary in other situations. When not in use, they can be stored in their case at the
rear of the printer.
If you choose to use them, you should place them on the platen when prompted by the front panel (this
prompt appears when using the loading accessory). Open the window, place the edge holders, then close the
window.
WARNING! Do not touch the printer's drying enclosure. Even after you have opened the window latch, which
disconnects the power to the drying and curing modules, the internal surfaces could be hot.
The edge holders should be placed on the platen so that they slightly overlap the left and right edges of the
substrate. The edge holders fit into holes in the platen, and they are magnetic, which helps them to stay in
place.
44 Chapter 4 Handle the substrate ENWW
Slide the edge holder to the left or right with your fingers so that you can see the edge of the substrate in the
two square holes in the side of the edge holder.
The following picture shows an edge holder correctly placed.
NOTE: When you use the edge holders, your prints should have a minimum margin of 10 mm.
NOTE: Remove the edge holders when the end-of-roll message appears.
The loading accessory
The loading accessory is designed to help in loading banner/textile/mesh substrates. It is recommended
when loading such substrates, but not obligatory.
The printer comes with two loading accessories: one for rolls up to 1.55 m (61 in) wide and one for rolls up to
2.64 m (104 in) wide. The smaller loading accessory can also be used for wide rolls if you prefer.
NOTE: The edge holders can be used whether or not you decide not to use the loading accessory.
1. Select Load with accessory from the Substrate Load menu on the front panel.
ENWW The loading accessory 45
NOTE: If you select Load with accessory, a message is displayed asking whether you want to use the
edge holders.
2. Lay the textile loading accessory on the floor and flip forward enough of the white flaps to cover the
width of the substrate.
3. Pull some of the substrate from the roll and put the leading edge on the loading accessory.
46 Chapter 4 Handle the substrate ENWW
4. Flip the white flaps back to cover the leading edge of the substrate. The black patches are magnetic and
grip the substrate.
5. Lift the loading accessory and the leading edge of the substrate together.
6. Load the substrate manually, see Load a roll into the printer (manually) on page 31.
ENWW The loading accessory 47
7. The loading accessory passes through the printer's substrate path with the substrate.
8. The front panel asks whether you want to use the edge holders. See The edge holders on page 44.
9. Select the type of substrate you are loading.
NOTE: You should select the name of the particular substrate that you are using in your RIP software,
not in the front panel.
TIP: When loading very thin substrates, always select the substrate type as Banner to minimize the
vacuum pressure applied while loading; when loading very thick substrates, always select the substrate
type as HP Photorealistic to maximize the vacuum pressure. After loading and before printing, go to
the front panel and change to the correct type for the substrate you are loading: press
, then ,
then Substrate > Change loaded substrate.
10. After passing through the printer, the loading accessory can be removed by hand.
11. The printer checks the substrate in various ways and may ask you to correct problems with skew or
tension.
NOTE: You can specify the maximum permitted amount of skew at the front panel: press , then
, then Substrate > Substrate handling options > Max skew setting.
48 Chapter 4 Handle the substrate ENWW
12. If you are loading transparent substrate without opaque borders, you are asked to enter the width of
the substrate and the distance of the right edge from the printer's side plate (as indicated by the ruler
on the front of the curing module).
13. If you have chosen double-sided printing, the front panel may ask a question about it at this point.
14. The printer calibrates the substrate advance.
15. The front panel recommends using the take-up reel. You can choose to load the take-up reel now, or
later during printing; or you can choose not to use it at all. See
16. Complete the loading process as usual and adjust the skew if necessary.
The take-up reel on page 35.
Double-sided printing
The printer can be used to print on both sides of the substrate, in the following way.
NOTE: The print should be at least 28 cm (11 in) wide, otherwise the printer will not be able to find the
reference line when printing the second side.
Outline
1. Tell the printer that you intend to print on both sides.
2. The printer prints the content that you want to appear on the first side. After each job, the printer prints
a black reference line that is used to align the matching job on the second side.
3. Cut and unload the substrate.
4. Reload the cut substrate upside down and starting at the end. The reference line marking the end of the
first side should be face down and near the leading edge.
5. The printer finds the reference line, and uses it to start printing the second side in the right place.
Double-sided printing can be selected in your RIP software or at the printer's front panel. The RIP setting
takes precedence: if double-sided printing is explicitly turned on or off in the RIP software, the front panel
setting is ignored.
NOTE: If you try to move the substrate while printing on either side, the front panel asks for confirmation,
because any such movement prevents correct alignment between the two sides.
ENWW Double-sided printing 49
Double-sided printing in detail
1. Load the substrate in the normal way for the substrate you are using.
2.
On the printer's front panel, press
Return to the home screen and check that the printer status is shown as Ready to print side A.
Alternatively, select double-sided printing in your RIP software.
NOTE: The automatic cutter and the extra bottom margin are both disabled during double-sided
printing.
3. Send one or more jobs to be printed on the first side. Before printing the first job, the printer may
advance the substrate by about 0.5 m (20 in) so that the second side can be completely cured. After
each job, the printer prints a black reference line that is used to align the matching job on the second
side.
NOTE: The chance of visible misalignment between the two sides increases with the length of the job.
For this reason, in double-sided printing you are recommended not to print any single job that is longer
than 3 m (10 ft).
4.
After printing, advance the substrate a little by going to the front panel and pressing
then Substrate > Move substrate.
●
If you plan to attach the substrate to the take-up reel before printing the second side, advance the
substrate enough to achieve this.
●
If you plan to attach the substrate to the take-up reel while printing the second side, advance the
substrate about 10 cm (4 in).
, then , then Substrate > Double-sided printing > Side A.
, then ,
5.
Cut the substrate, either manually or by going to the front panel and pressing
Substrate > Form feed and cut. Before cutting, ensure that the total length of the cut substrate is more
than 2 m (6 ft 7 in), otherwise you may be unable to load it successfully.
NOTE: The Form feed and cut command will not work if the substrate cannot be cut by the cutter.
6.
Press
7. Reload the substrate with the first (printed) side facing up as it enters the printer, and with the
reference line near the leading edge. Reload if necessary until the printer finds less than 1 mm/m skew.
TIP: Although it is not strictly necessary, you may find it quicker to use the manual loading procedure
as an initial approximation, and then allow the printer to find the reference line more accurately. See
Load a roll into the printer (manually) on page 31. If you use only the automatic loading procedure, the
printer may take some time to find the reference line.
TIP: You are recommended to use the edge holders when printing the second side, which means using
the manual loading procedure.
TIP: If you have deliberately not attached the substrate to a spindle, and the front panel reports that
the substrate may be detached from the core, or that the feeding direction is not detected, you can
ignore the message and continue.
8. The front panel asks, Would you like to load substrate for printing as side B? Select Yes.
, then , then Substrate > Substrate unload.
, then , then
9. The printer searches for the reference line on the substrate. If it fails to find it, the front panel asks you
to move the substrate using the Up and Down keys until the reference line is aligned with the
permanent line on the platen. You may find it useful to mark where the reference line is on the other
side of the substrate.
50 Chapter 4 Handle the substrate ENWW
NOTE: If you know that the automatic search for the reference line is not working (perhaps because
the substrate-advance sensor is dirty), you can turn it off: press
Substrate handling options > Enable auto line detection > Off.
10. Send one or more jobs to be printed on the second side. If you send more than one job, they should be
sent in reverse order, because printing starts at the end of the second side and works back towards the
beginning.
NOTE: The jobs printed on the second side should probably be rotated 180 degrees, and may need to
be slightly reduced in size to compensate for the contraction of the substrate after passing once
through the printer. See
The substrate has shrunk or expanded on page 137.
View information about the substrate
On the front panel's home screen, press .
The following information appears on the front panel:

The same information appears on the Embedded Web Server's Supplies page.
Substrate length tracking
The substrate length tracking feature enables you to keep track of how much substrate you have used and
how much is remaining on the roll.
1. When the roll is first loaded onto the printer you have the option to enter the length of substrate on the
roll. The amount of substrate that is subsequently used is then tracked.
ENWW View information about the substrate 51
2. When the substrate is unloaded, the front panel displays the amount remaining so that you can note it
for future reference.
3. Next time the substrate is loaded, you can enter the remaining length, and the printer again tracks the
substrate as it is used. If the substrate was never actually unloaded, for example if there was a
substrate jam and the substrate was unloaded and the printer was turned off and on, if you select Last
known length the printer will apply the values from when the jam occurred (if the tracking feature was
enabled).
The remaining length of substrate is always displayed in the Substrate area of the front panel. This
information may also be displayed in your RIP.
Enable/disable the length tracking feature
1.
The length tracking feature can be disabled or enabled from the front panel. Press
, then ,
then Substrate > Substrate handling options > Substrate length tracking.
2. Select On or Off.
52 Chapter 4 Handle the substrate ENWW
Form feed and cut
The Form feed and cut option is available from the printer's front panel. If you press , then , then
Substrate > Form feed and cut, the printer normally advances and cuts the substrate. Here is a list of its
other functions:
●
If the printer is waiting for more pages to be nested, Form feed and cut cancels the waiting time and
prints the available pages immediately.
●
If the printer is drying the ink after printing, Form feed and cut cancels the waiting time and releases
the page immediately.
●
If the take-up reel is enabled, Form feed and cut advances the substrate 10 cm (3.9 in), but does not cut
it.
NOTE: The cutter is disabled when the take-up reel is in use, and when a banner or textile substrate is
loaded.
Store the substrate
The following are tips for storing substrate:
●
Always keep unused rolls wrapped in the plastic wrap to prevent discoloration and dust accumulation.
Rewrap partially used rolls if they are not being used.
●
Do not stack rolls.
●
Allow all substrates to adapt to room conditions out of the packaging for 24 hours before printing.
●
Handle film and glossy substrates by the edges or wear cotton gloves. Skin oils can be transferred to
the substrate, leaving fingerprint marks.
●
Keep the substrate tightly wound on the roll throughout the loading and unloading procedures. If the
roll starts to unwind, it can become difficult to handle.

5 Substrate settings
Download media presets
Each supported substrate has its own characteristics. The printer changes the way it prints on each different
substrate. The RIP requires a description of the requirements of each substrate. This description is called the
“media preset”.
The media preset contains the ICC color profile, which describes the color characteristics of the substrate. It
also contains information about other characteristics (RIP and printer settings, such as drying and curing
temperatures, vacuum pressure and substrate advance compensation) and requirements of the substrate
that are not directly related to color. Media presets for your printer are installed in the RIP.
The RIP contains media presets for only the most commonly used substrates. If you buy a substrate for which
your RIP has no preset, you can obtain a preset for a new substrate in the following ways:
●
Try to download the media preset from the substrate manufacturer's Web site.
●
If it is not there, try to download it from the RIP company's Web site.
●
If it is not there, check availability using the HP Media Finder search application located at
http://www.hp.com/go/latexmediafinder/
●
If you cannot find it anywhere, create a new media preset in the RIP, or copy a similar existing media
preset and modify it. See
●
Further information can be found at
Add a new substrate
This section is provided in case you decide to make your own media preset. Normally there is no need to do
this if you can find ready-made presets for all the substrates that you use.

The various settings mentioned above are described below.
Setting Description If too low If too high
Passes The number of passes specifies
how many times the printheads
will print over the same area of
the substrate.
Drying temp. The heat applied in the printing
zone removes water and fixes the
image to the substrate.
Curing temp. Curing is needed to coalesce the
latex, creating a polymeric film
which acts as a protective layer,
while at the same time removing
the remaining co-solvents from
the print. Curing is vital to ensure
the durability of the printed
images.
The amount of ink fired per time
unit is larger and ink has less time
to dry on the substrate. This may
create coalescence and banding.
The boundaries between passes
may be more visible. However,
printing speed is relatively high.
Print-quality defects such as
banding, bleeding and coalescence
may occur.
The print may emerge not fully
polymerized, so that the ink
smears when rubbed. The print
may appear wet, after printing or
later. You may need to increase
the number of passes to achieve
adequate curing.
Colors are vivid, print quality is
high. However, printing speed is
relatively low. A lower curing
temperature is needed, otherwise
the substrate may be deformed.
Thermal marks may be seen on
the substrate; they may appear as
vertical bands in some colors. The
substrate may wrinkle on the
platen, causing vertical banding,
ink smears or substrate jams.
The substrate may wrinkle under
the curing module, causing
defects such as blisters or liner
detachment. The substrate
wrinkles may also cause vertical
banding or ink smears at the
beginning of the following plot.
Heating airflow Airflow helps to remove the
Substrate advance
compensation
evaporated water from the print
zone and thus allows more
efficient drying.
Your printer was calibrated at the
factory to ensure that it advances
the substrate accurately when
using supported substrates in
normal environmental conditions.
However, you may find it useful to
adjust the substrate advance
when printing in an unusual but
stable temperature or humidity
level, or if the substrate-advance
sensor is not working.
In general, use the substrate family default value.
You may see horizontal banding or
grain.
You may see horizontal banding or

ENWW Add a new substrate 57
Setting Description If too low If too high
Input tension Tension is applied to the substrate
from the input spindle. It needs to
be constant over the full width of
the substrate, thus substrate load
is a critical operation.
Vacuum The vacuum applied to the
substrate at the printing zone
helps to hold the substrate down
on the print platen, keeping the
distance to the printheads
constant.
Bidirectional Specifies whether printheads print
in both directions, when moving
from left to right and from right to
left.
High ink level The maximum quantity of ink will
be laid on the substrate (the High
ink level option available only
when the number of passes is 10
or more). The ink quantity may be
reduced by the RIP color profile.
The substrate skews and may
become increasingly wrinkled in
the printing zone. Also, substrate
advance may be irregular,
resulting in horizontal banding.
The substrate may lift up off the
platen and touch the printheads.
This can smear the printed image,
cause vertical banding, cause a
substrate jam or even damage the
printheads.
If Bidirectional is selected, the
amount of ink fired per unit of
time is larger, and therefore print
quality defects such as
coalescence and banding may
occur, especially at the sides of
the plot. However, printing speed
is high.
If not selected, colors may look
washed-out.
The substrate may be
permanently deformed or
damaged. Substrate advance
problems may appear in extreme
cases.
For sticky substrates, friction
could be too high and substrate
advance irregular, resulting in
horizontal banding or irregular
grainy patches.
If Bidirectional is unchecked then
the printing is unidirectional and
the speed is relatively low.
TIP: You are recommended to
keep Bidirectional selected in all
cases, increasing the number of
passes if necessary to avoid
coalescence and banding.
If selected, there can be excess of
ink and some problems related to
poor drying and curing.
TIP: Select High ink level for
backlit and some textile
applications, or if you want high
color saturation.
Cutter The printer's built-in cutter can cut
the substrate automatically
between each print.
Auto tracking (OMAS) The substrate-advance sensor
(also known as the Optical Media
Advance Sensor, OMAS) is located
under the print platen; it can track
the substrate advance
automatically.
Disable the cutter in the following cases:
●
You want to increase the speed of printing.
●
You want to use the take-up reel.
●
You want to cut the substrate manually.
●
The leading edge of the substrate tends to curl and cause
substrate jams.
In some cases, the cutter is automatically disabled.
Disable the sensor in the following cases:
●
The substrate allows ink to pass through to the platen. Clean the
sensor after using this substrate.
●
You are instructed to do so by the front panel, because the sensor
is dirty or unable to track this particular substrate.
Load the substrate and print the diagnostic plot
1. Load the substrate in the normal way, paying particular attention to the following points.
58 Chapter 5 Substrate settings ENWW
●
The stop at the right-hand end of the spindle has two possible positions on the spindle. Always use
the leftmost position if possible. Use the rightmost position only if the substrate roll requires the
full width of the spindle.
●
Turn off the substrate-advance sensor (OMAS) in the RIP if the substrate is transparent or its
underside is dark, or if the printer recommends you to do so.
●
Align the printheads.
2. Open the HP diagnostic chart in the RIP. The chart is stored in your printer, at http://ip-addr/hp/device/

3. Select a suitable number of passes for the substrate family. See
on page 61.
4. Reset your print mode to default category values for that print mode.
5. Print the plot.
Change settings while printing
You can use the front panel to change the following settings while printing.
●
To change temperature, vacuum and inter-pass dry time settings while printing: press
Adjustments, and choose the setting that you want to adjust. You can use the arrow keys to adjust the
curing temperature, the drying temperature, the vacuum pressure or the inter-pass dry time (delay
between passes). The changes that you make take effect immediately, but they are not saved: the next
job will use the settings in the media preset as usual. If you want to change the settings permanently,
you must change them in the media preset in the RIP.
●
To change substrate advance calibration while printing (in case of banding): press

Advanced settings
Here are some more advanced settings, which you are not recommended to change, unless you have
problems that you cannot resolve any other way.
The drying and curing temperatures used by the printer are determined by adding the offset to the base
temperature. The base temperatures shown in the table are the default values for each substrate family, but
may be changed by the printer depending on the printer settings in use. You cannot change the base
temperatures yourself, but you can change the offsets. The base warm-up drying temperature is determined
by the RIP.
Your RIP may have an option to return all settings to their default values.

Tips
●
4 to 16 passes should cover most printing needs.
●
2 to 6 passes provide lower print quality. Also, the color gamut will be slightly reduced, as total ink is
limited to allow for drying and curing.
62 Chapter 5 Substrate settings ENWW
●
For time-critical applications, 2 to 16 passes using a higher carriage speed (1.5 m/s (60 in/s) versus the
standard speed of 1 m/s (40 in/s)) can be selected from the RIP.
◦
The increased carriage speed provides about a 15 to 30% gain in throughput (m²/h).
◦
Minor color shifts may be noticed if you reuse presets obtained with the standard carriage speed.
You may wish to create a new preset for the higher carriage speed.
●
For high-ink applications, you are recommended to use at least 8 passes, depending on the substrate
family. Print modes of 20 and more passes have been included to ensure proper drying and curing in
certain cases.
●
1200 dpi print resolution is available in the 18-pass print mode only. Make sure you have a specific
media preset for this print mode, because reusing others may not deliver the expected print quality.
●
For fast layout proofing on cheap substrates, a low-ink 2-pass print mode has been enabled on paperbased substrates. This mode is not intended for use with higher-quality substrate families, as drying
and curing will not work properly. This is not designed to be a production print mode, but for occasional
usage, as prolonged 2-pass printing may harm your printheads.
Check the quantity of ink on the substrate
Check that the ink quantities in your media preset are adequate. Look at the color patches in the HP
diagnostic chart and check that the patches have the correct amount of ink using the guidelines below:
1. Too much ink: There are several possible symptoms of this problem.
●
The last two or three scales of the chart look the same.
●
Vertical bands.
ENWW Add a new substrate 63
●
Horizontal bands.
●
Coalescence, grain (can be caused by an excess of light ink).
Try reducing the amount of ink in your RIP software, then reprint the chart and check again.
You may have chosen a media preset that uses more ink than your substrate allows. Consult your RIP
documentation to make sure you’re applying the right media preset, and to find out how to lower the
total ink limits of the media preset. For a quick solution, you could change to a different media preset
that uses less ink: for example, paper-aqueous presets use less ink than self-adhesive presets.
2. Correct amount of ink: The top level of each patch shows a smooth gradient, there are no visible
defects and increasing amounts of ink result in increasing color density.
64 Chapter 5 Substrate settings ENWW
3. Too little ink: The whole chart looks washed out.
Try increasing the amount of ink in your RIP software, then reprint the chart and check again.
You may have chosen a media preset that uses less ink than your substrate allows. Consult your RIP

NOTE: Backlit and some textile substrates usually need to be used with the “High Ink Limit” option enabled
in the RIP.

Faster printing
The obvious way to increase speed is to reduce the number of print passes and/or increase the carriage
speed to 1.5 m/s (60 in/s), although these will tend to reduce print quality. Bear in mind the following
considerations.
●
With fewer than 10 passes, you may see an increase in grain.
●
With fewer than 8 passes, the printer is more sensitive to substrate advance problems.
●
With fewer than 8 passes, you may need to reduce the ink quantity to improve print quality.
●
With carriage speed at 1.5 m/s (60 in/s), you may need longer inter-pass drying times or a lower ink
quantity for proper drying.
●
If you want to use the high ink level option, you must use at least 10 passes.
●
As you reduce the number of passes, the best curing temperature may be more difficult to find, and may
be more sensitive to the ambient temperature and humidity.
Here are some other suggestions for increasing the speed of printing.
●
Concatenating prints saves time, because one can be sent while another is being printed.
●
Disable the cutter: press
With most substrates, this saves some time at the end of the printing process.
●
Increase the cool-down curing temperatures. This also saves some time at the end of the printing
process, but may cause slight substrate deformation, depending on the substrate.
NOTE: Printing continuously for more than 2 hours can reduce the life of the printheads. An occasional brief
pause allows the printer to service the printheads.
See also The printer seems slow on page 146.
Color calibration
The purpose of color calibration is to produce consistent colors with the specific printheads, inks and
substrate that you are using, and in your particular environmental conditions. After color calibration, you can
expect to get identical prints from your printer on different occasions.
Color calibration can be launched from your RIP software; see your RIP documentation for details.
In outline, the process consists of the following steps.
1. A calibration test chart is printed.
2. The HP Embedded Spectrophotometer (or, if you prefer, a different spectrophotometer) scans and
measures the test chart.
, then , then Substrate > Substrate handling options > Cutter > Off.
3. The RIP uses the measurements to calculate the necessary correction factors for consistent color
printing on that substrate.
Color calibration with the Embedded Spectrophotometer is not recommended for the following substrate
types. It may be possible to calibrate some of these substrates by using an external color measurement
device.
●
Non-opaque substrates such as clear film, backlit substrates, and some textiles.
●
Substrates with an uneven surface, such as perforated vinyl or punched-window substrates.
66 Chapter 5 Substrate settings ENWW
●
Substrates that suffer deformation from drying and curing, such as paper-based substrates.
●
Very elastic substrates, such as some textiles without liner.
Substrates suitable for color calibration include even-surfaced adhesive vinyls (neither punched nor
perforated), PVC banners and some opaque, stiff textiles.
Some textiles require the take-up reel for successful printing. However, the take-up reel may fail to cope
with the backward movement of the substrate between the printing and scanning phases of color calibration.
To avoid this problem, proceed as follows.
1. Ensure that the take-up reel is enabled.
2. Advance the substrate until the tension bar reaches its lowest position.
3. Manually rewind the take-up reel, using the buttons on the take-up reel motor, to collect the substrate
and raise the tension bar until it almost touches the take-up reel.
4. Set the take-up reel's winding direction to neutral.
5. Launch color calibration from the RIP.
6. When the color calibration has finished, you can re-enable the take-up reel.
Color profiles
Color calibration provides consistent colors, but consistent colors are not necessarily accurate. For instance,
if your printer prints all colors as black, its colors may be consistent but they are not accurate.
In order to print accurate colors, it is necessary to convert the color values in your files to the color values
that will produce the correct colors from your printer, your inks and your substrate. A color profile is a
description of a printer, ink and substrate combination that contains all the information needed for these
color conversions.
NOTE: Although color profiles obtained in one particular print mode can be reused when printing with other
print modes, the most accurate color reproduction can only be achieved if profiling is made with exactly the
same print mode that is used for printing. For example, if you use a color profile obtained with a 10-pass
STANDARD print mode, you may see some color difference when you use it to print with an 8-pass SPEED
print mode
These color conversions are performed by your Raster Image Processor (RIP), not by the printer. For further
information on the use of color profiles, see the documentation for your application software and for your
RIP.
In addition to the color profiles used for printing, you may wish to calibrate and profile your monitor (display
device), so that the colors you see on the screen relate more closely to those that you see on your prints.
Color reproduction tricks
Latex inks are a new technology, and there are some important guidelines when doing color separations
(such as when creating or modifying a new media preset within your RIP) that will help to optimize the printer
output in terms of color gamut, ink usage and print quality. These are as follows:
●
To achieve the best dark colors in vinyl gloss and other substrates, use as much black and as little
composite (CMY) as possible when creating the ICC profile.
●
Light inks should be avoided as much as possible in high-density colors such as secondaries and
tertiaries (dark red, blue, green, ...).
●
Light inks should be restricted to the lowest-density colors, starting the use of dark inks as early as
possible. Typically, a color of more than 50% density should not contain any light inks.
ENWW Color profiles 67
●
Light inks should be used at no more than 50% of maximum quantity. An excessive amount of light inks
can create gloss artifacts in vinyl gloss substrates.
●
For tiling applications, using the RIP to add a small inter-pass delay of 0.5 to 1 second will yield better
color matching from left to right.
Please refer to your RIP documentation for details of how to create or modify media presets.
Presets for HP-branded substrates have been created following the above recommendations in order to
optimize black and dark colors. You can find the HP media preset for your substrate family at

7 The ink system
Ink system components
Ink cartridges
The printer's six ink cartridges provide magenta, light magenta, black, yellow, light cyan and cyan ink to the
printheads. Each cartridge has a capacity of 775 ml.
Ink cartridges require no maintenance or cleaning, but must be shaken before installation. High-quality
printing results continue even when the ink levels are getting low.
CAUTION: Avoid touching pins, leads, and circuitry when handling ink cartridges because these elements
are sensitive to electrostatic discharge. Such devices are called ESD-sensitive devices. See
on page 161. Electrostatic discharges are one of the main hazards to electronics products. This type of
damage can reduce the life expectancy of the device.
Printheads
The printheads deposit ink on the substrate. Each printhead is connected to two ink cartridges. For example,
the printhead shown below draws ink from the light magenta and magenta cartridges.
Glossary
The printheads are extremely durable and do not need to be replaced every time an ink cartridge is replaced.
They provide excellent results even when the ink cartridges contain a low level of ink.
ENWW Ink system components 73
To maintain optimum print quality, the printheads are automatically tested at regular intervals, and
automatically serviced when necessary. This takes a little time and can occasionally delay printing.
When a printhead eventually needs to be replaced, the front panel will display a message.
CAUTION: Avoid touching pins, leads, and circuitry when handling printheads because these elements are
sensitive to electrostatic discharge. Such devices are called ESD-sensitive devices. See
on page 161. Electrostatic discharges are one of the main hazards to electronics products. This type of
damage can reduce the life expectancy of the device.
Printhead cleaning kit
The printhead cleaning kit contains the printhead cleaning cartridge, the ink funnel and the ink filter.
Printhead cleaning cartridge
The printhead cleaning cartridge cleans and maintains the printheads, and seals the printheads when they
are not in use to prevent them from drying out.
Glossary
Ink funnel
The cartridge contains a roll of cloth, which is used to clean the printheads. You are notified when 92% of the
roll has been used, after which the cartridge should continue to function for about another 140 m² (1500 ft²)
of printed area. A new roll lasts for about 1850 m² (20000 ft²) of printed area.
NOTE: These figures can vary considerably depending on the image density, the print mode, and the
ambient temperature. The cloth will be exhausted much faster with a high-density print, many passes, a hot
environment, and if you have selected the Extra PH cleaning option in the front panel because of a printquality problem (see
need it.
NOTE: The printhead cleaning cartridge is checked to detect end of roll when the printer is turned on and at
the end of each print job.
The printer will refuse to start a print job if it detects the end of the cleaning roll. You should then replace the
printhead cleaning cartridge with a new one.
The ink funnel collects waste ink produced during printhead servicing. It is important that this funnel is
installed, as it prevents significant deposits of ink over various other printer parts.
From the ink funnel, the waste ink passes through the ink tube assembly into the printhead cleaning
container.

filter at the same time.
●
The ink filter, which filters tiny droplets of waste ink before they pass into the printhead cleaning
container.
These components are designed to keep the printer's waste ink from damaging the printer and dirtying the
environment.
In order to keep the printer and its surroundings clean, you must ensure that these components are correctly
installed and maintained. In particular, these steps are essential:
1. Connect the ink tube assembly.
2. Insert the ink funnel.
3. Insert the ink filter and close the filter box.
4. Install the printhead cleaning container.

Finishing: The printer is cooling down and preparing for stand-by. This takes 0.5 to 5 min.
If jobs of the same print mode as the already-printed file are sent while the printer is Curing (if the cutter is
not enabled) or Finishing, the printer goes to Preparing to print.
To save time between prints, concatenate jobs with the same print mode (same number of passes) and turn
the cutter off to skip the Curing and Finishing states. You can also use nesting to print several jobs in the
same workflow.
Even if the cutter is on or successive jobs use different print modes, it is better to print them all together
without delays to minimize the time spent in Preparing to print.
Change margins
The printer margins determine the area between the edges of your image and the edges of the substrate.
The margins for a particular print job are selected in the RIP software; if the job exceeds the substrate width,
it will be clipped.
The front panel offers additional settings for the bottom margin: see
settings apply only to single prints when the cutter is not in use. The bottom margin is not applied between
several prints sent at the same time, nor during double-sided printing.

Ink system tips
For best results, always follow these guidelines:
●
Follow the instructions on the front panel during installation.
●
Allow the printer and the printhead cleaning cartridge to clean the printheads automatically.
●
Avoid unnecessary removal of the ink cartridges and printheads.
●
The ink cartridges should never be removed while the printer is printing. They should be removed only
when the printer is ready for you to replace them. The front panel guides you through the replacement
procedure.
●
Make sure that you comply with all applicable laws and regulations when disposing of ink system
consumables.
NOTE: Shake the ink cartridges and printheads vigorously before installing them.
Align the printheads
The printer performs printhead alignment whenever printheads are replaced. If no substrate is loaded when
a printhead is replaced, the printer will perform the alignment the next time you load substrate.
You may also be recommended to align the printheads to solve a print-quality problem.
Automatic alignment
First make sure that you have a roll of opaque, white substrate loaded in the printer. Colored substrates,
glossy canvas, coarse textiles, and transparent materials such as translucent bond, clear film, tracing
substrate and vellum are not suitable for automatic printhead alignment. For these substrates, you should
align the printheads manually (see
supported substrate first, then change to the special substrate. Alignment settings are retained through
substrate changes until a new printhead alignment is performed.
To request printhead alignment from the front panel (if the alignment is not performed automatically), press
, then , then Ink > Image-quality maintenance > Align printheads > Auto PH alignment.

3. Clean the carriage rail using a lint-free cloth dampened with 95% ethanol. Take care to clean the whole
rail, including the part under the left cover.
NOTE: 95% ethanol is not provided in the Maintenance Kit.
CAUTION: Ethanol is highly flammable. Observe the manufacturer’s safety precautions.
CAUTION: Do not use commercial cleaners or abrasive cleaners.
CAUTION: While cleaning, be careful not to damage the metal strip located on top of the rail.
4. Wait until the rail is dry, then close the window. The carriage moves to the center of the printer so that
you can reach the part of the rail under the right cover.
5. Unlock and open the printer window.
6. Clean the carriage rail area under the right cover as described in step 3.
7. Take the bottle of oil from the Maintenance Kit that is supplied with your printer (a replacement kit can
be ordered if necessary).

8. Deposit a very thin zig-zag trickle of oil along the rail on both sides of the carriage. There is a video
showing the process here:
NOTE: While lubricating, be careful not to drop oil on the metal strip located on top of the rail.
9. Clean the substrate jam reflector using a lint-free cloth dampened with distilled water. If you find dried
ink that you cannot remove, try using a lint-free cloth dampened with 95% ethanol.

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.
A carriage interconnect wiper is included with your printer in the User Maintenance Kit.
92 Chapter 12 Hardware maintenance ENWW
Use this 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. Remove a new pre-moistened replacement sponge from its pouch.
A supply of sponges is included in the box with the wiper. If all sponges have been used, more can be
obtained by calling your service representative.
2. Open the carriage interconnect wiper.
ENWW Clean the electrical connections on a printhead 93
3. Load the sponge by positioning the sponge on the face of the carriage interconnect wiper with the
shorter tab in the locating slot.
4. Close the carriage interconnect wiper, trapping the sponge in place.
5. Open the printhead carriage latch and extract the printhead that is causing the problem, as indicated on
the front panel. See
Replace a printhead on page 110.
6. Insert the carriage interconnect wiper into the printhead slot at the back. Wipe the electrical contacts by
inserting the tool between the electrical connections at the back of the slot and the steel spring, with
the sponge facing away from you and towards the electrical contacts. Try to avoid picking up any ink
deposit that may have accumulated 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.
