may vary depending on the substrate. Please consult your substrate supplier for compatibility details.
Substrate tips
General tips
Handle unprinted and printed substrates with care, and preferably with cotton gloves, to avoid
fingerprints. For heavy rolls, use a forklift, and two people wearing security shoes.
Before loading a roll:
Check that temperature and humidity in the room are within the recommended ranges for the
●
printer. See
Check that neither the roll nor its core are bent or deformed, which may cause the substrate to jam
●
in the printer.
If the roll has been stored in a place not offering the recommended environmental conditions,
●
allow some time for it to adapt to the temperature and humidity of the printer's environment.

Check which is the correct side for printing, by reading the label inside the core or the note
●
inserted into the package (or see
Check that the substrate is correctly attached to the input core. Otherwise, you will see poor print
●
quality due to substrate advance errors.
You may find it easier to load a roll if you first move the carriage beam to its highest position.
●
While loading a roll, make sure the leading edge is parallel and straight across the output core, and
attached evenly (start taping the substrate to the core at the center, then move towards the edges).
After you have loaded a roll:
Make sure that the edge holders are set on both sides of the roll. Do not use any other Edge
●
holder from another printer, only use the edge holders that came with the printer. An incorrectly
loaded roll may cause waves or cockles in the substrate, leading to ink smearing and printhead
crashes.
Check the correct carriage beam position for printing: high for thick substrates, normal for others.
●
See
Set the carriage beam position on page 25.

ICC profile and other settings in the RIP.
HP substrates are optimized to provide the best out-of-the-box printing experience with your
●
printer. However, you may want to modify the ink limits or the number of passes; in which case,
temperature, vacuum or tensions may need to be adjusted. You can create a new substrate preset
from the default preset you are using and make your changes.
Tips for specific substrates on page 23).
Use the HP Internal Print Server to check that any required calibrations have been done: color
●
calibration, substrate-advance compensation, printhead alignment. See the Maintenance and
troubleshooting guide.
For the best print quality, the substrate should stay flat and unwrinkled in the printing zone, the
●
substrate advance should be constant and the substrate should move straight.
Do not cut off pieces of substrate while the substrate is loaded into the printer. This may cause the
●
remaining substrate to jam.
After printing, try to allow 24 hours before stacking, folding or rolling printed substrates.
NOTE: Printing on porous substrates may result in visible vapor being generated from the water-
based ink.

Substrate configurations
The substrate can be loaded in a variety of different configurations to suit your different needs. Before
loading, you must go to the HP Internal Print Server and select Substrate > Load/Unload, then
select the configuration you intend to use.
Handle the substrate
The basic configurations are illustrated below. These configurations can be used for single-roll or dualroll printing, and for porous or non-porous substrates. Porous substrates require the use of the ink
collector kit: see
The roll-to-roll configuration is suitable when you intend to print a whole roll without cutting
●
it until the input roll is empty. The substrate cannot be cut in mid-roll unless printing double-sided,
and then it must be reloaded afterwards.
The roll-to-free-fall configuration (LX850 only) is suitable when you want to cut and
●
remove each print as soon as it comes out of the printer. The substrate is kept under tension
between the input roll and the tension roller; but it can be cut after the tension roller because then
it is no longer under tension.
The ink collector kit (LX850 only) on page 28.
24 Chapter 3 Handle the substrate ENWW
The roll-to-free-fall with collector configuration (LX850 only) is suitable when you may
●
want to cut the substrate and remove the output roll before the input roll is empty. The substrate is
kept under tension between the input roll and the tension roller; but it can be cut after the tension
roller because then it is no longer under tension.
Set the carriage beam position
The carriage beam position determines the vertical distance between the printheads and the platen. If it
is too great, print quality will be impaired. If it is too small, there is a risk that the printheads will come
into contact with the substrate, causing smears or damage.
To set the carriage beam position, go to the front panel and select the Substrate menu
Substrate management, and press OK. Select Carriage beam position. You can choose the
highest position, a custom position or the normal position.
The highest position is not used for printing: it may be used for loading substrate or for
●
maintenance tasks.
A custom position is used for thick substrates, or for substrates that wrinkle slightly due to heating.
●
TIP: Try to avoid wrinkling by using substrates that do not wrinkle, or by using a slower print
mode that will allow you to lower the drying temperature.
We recommend setting the custom position to the thickness of the substrate plus two or three
millimeters. The current setting is indicated in the front panel by a √ mark.
, then
Handle the substrate
ENWW
The normal position is suitable for unwrinkled substrates up to 0.7 mm (0.03 in) thick.
●
WARNING! Keep away from the printer's moving parts until the carriage beam has reached its new
position.
Set the carriage beam position
25
NOTE: LX850 only: If you have installed the ink collector kit, the normal position and the lowest
custom position are automatically adjusted to take account of that.
Prepare to print
The following steps that must be followed before the printer can print:
1. Ensure that the ink collector kit is installed for porous substrates, and not installed for non-porous
substrates. See
The ink collector kit (LX850 only) on page 28.
2. Start the printer. See
3. Go to the HP Internal Print Server and select Substrate > Load/Unload to open the Printer
Configuration window.
4. Select the printer configuration that you intend to use, and press Next to see the on-screen help.
Handle the substrate
Turn the printer on and off on page 12.
NOTE: The Skip Substrate load check box should be checked only if the printer has just
previously had the same configuration (i.e. the same substrate, same profile), and because of a
severe system error, you had to restart the printer.
5. Load the substrate. Substrate loading instructions are displayed in the HP Internal Print Server
window. For more detailed instructions, see
roll into the printer on page 38.
6. Press the Load button in the HP Internal Print Server to start the substrate check, then enter the
substrate type in the Loaded Substrate window.
TIP: If the printer has been idle overnight with substrate loaded, and exposed to high or low
temperatures, advance the substrate 13 to 25 cm (5 to 10 in) before printing, to avoid printhead
crashes or ink smears on the substrate.
