							2 Connectivity and software instructions
Connection method
Your printer can be connected in the following way.
Connection typeSpeedMaximum cable lengthOther factors
Gigabit Ethernet Fast; varies according to
network trafficLong (100 m=328 ft) Requires extra equipment
(switches)
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 printers IP address
appear on the front panel (192.168.1.1 in this example). Make a note of the IP address: you can use it
later to access the Embedded Web Server.
If you see this screen without the IP address, either the printer is not successfully connected to the
network, or your network has no DHCP server. In the latter case, you will have to set the IP address
manually: see the Maintenance and troubleshooting guide.
Refer to the RIP instructions (not provided by HP) to install the software RIP.

							3 Basic setup options
Printer setup options
Turn the printer on and off
To turn on the printer, ensure that the power switch at the rear of the printer is turned on, ensure that
the residual current circuit breakers are in the up position, then 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, and then press the Power button.
When the printer is turned on, it will take about ten minutes to initialize itself.

							Restart the printer
In some circumstances you may be advised to restart the printer. Please proceed as follows:
1.Press the Power button on the front panel to turn the printer off. Wait a few moments, and then
press the Power button again. This should restart the printer. If it does not, continue with step 2.
2.Use the Reset button on the front panel. You will need a non-conductive implement with a narrow
tip to press the Reset button. This normally has the same effect as pressing the Power button, but
may work if the Power button does not.
3.If neither steps 1 nor 2 seems to have any effect, 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.
4.Remove the power cords from the power sockets.
5.Wait for 10 seconds.
6.Reinsert the power cords into the power sockets and turn on the printer by using the power switch.
7.Make sure that the Power light on the front panel illuminates. If it does not, use the Power button
to turn on the printer.
Change the language of the front panel
Two methods are available to change the language that is used for the front-panel menus and
messages.
●If you can understand the current front panel language, go to the front panel and select the 
 icon,
and then select Front panel options > Select language.
●If you cannot understand the current front panel language, start with the printer powered off. At the
front panel, press the OK button and hold it down. While holding down the OK button, press the
Power button and hold it down. Continue to hold down both buttons until the green light on the left
side of the front panel starts flashing, and then release both buttons. You can expect a delay of
about one second. If the green light starts flashing without any delay, you may need to start again.
Whichever method you used, the language selection menu should now appear on the front panel.
Highlight your preferred language, and then press the OK button.

							Request e-mail notification of specific error conditions
1.In the Embedded Web Server, go to the E-mail server page on the Setup tab and ensure that the
following fields are correctly filled in:
●SMTP server. This is the IP address of the outgoing mail server (Simple Mail Transfer Protocol
[SMTP]) that processes all e-mail messages from the printer. If the mail server requires
authentication, e-mail notifications will not work.
●Printer e-mail address. Each e-mail message that the printer sends must include a return
address. This address does not need to be a real, functional e-mail address, but it should be
unique, so that recipients of the message can identify the printer that sent it
2.Go to the Notification page, which is also on the Setup tab.
3.Click the New icon to request new notifications, or click the Edit icon to edit notifications that have
already been set up. Then specify the e-mail addresses to which notifications are sent, and select
the incidents that result in notification messages.
Change the sleep mode setting
If the printer is left turned on but unused for a certain period of time, it automatically goes into sleep
mode to save power. The default period of time it waits is 30 minutes. To change the time the printer
waits before it goes into sleep mode, go to the front panel and select the 
 icon, and then select Front
panel options > Sleep mode wait time. Highlight the wait time that you want, and then press the OK
button.

							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.
Use substrate
Choosing the correct substrate for your needs is an essential step in ensuring good print quality. For
best printing results, use only recommended HP substrates (see 
Supported substrate families
on page 16), which have been developed and thoroughly tested to ensure reliable performance. All
printing components (printer, ink system, and substrate) have been designed to work together to offer
trouble-free operation and ensure optimal print quality.
Here are some additional 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.
●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.
●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.
●If the substrate family shown on the front panel does not correspond to the substrate that you intend
to use, take one of the following actions:
◦Reload the roll into the printer and select the correct substrate family. See 
Unload a roll from
the printer on page 25 and Load a roll into the printer (automatically) on page 19.
◦At the printers front panel, select the 
 icon, and then select View loaded substrate >
Change loaded substrate.
NOTE:Substrate advance calibration is not performed when the substrate family is changed
from the front panel.
