							3.Remove the first end of the spindle from the right side of the printer, and then move the spindle to
the right in order to extract the other end. Do not insert your fingers into the spindle supports during
the removal process.
The spindle has a stop at each end to keep the roll in position. Remove the blue stop at the left
end to mount a new roll (the stop at the other end can also be removed, if you wish). The stop
slides along the spindle to hold rolls of different widths.
4.Slide the lever-lock on the blue stop to the unlocked position.
5.Remove the stop from the left end of the spindle.

							6.Rest the roll of substrate that you want to load on the loading table. If the roll is long and heavy,
you may need two people to handle it.
7.Slide the spindle into the roll.
8.The right stop of the spindle has two positions: one for rolls of the printers maximum width, and
another for narrower rolls.

							9.Put the blue stop on to the upper end of the spindle, and push it towards the end of the roll.
TIP:If the cardboard core of the substrate is longer than the substrate, you can load the media
without inserting the blue stop, but care should be taken when unloading the media, as the loading/
unloading table is designed to be used with the blue stop in place.
10.Slide the lever-lock to the locked position.
11.Lift the loading table to ease the spindle into the printer.
CAUTION:To avoid trapping your fingers, do not push the roll with your hands.
If you regularly use different substrates, you can change rolls more quickly if you pre-load rolls of different
substrates on different spindles. Extra spindles are available for purchase.
Load a roll into the printer (automatically)
To start this procedure, you need to have a roll loaded on the spindle. See Load a roll onto the
spindle on page 16.
The normal minimum substrate width is 23 inches (584 mm). To load substrates down to a minimum
width of 10 inches (254 mm), go to the front panel and select the 
 icon, then select Substrate handling

1.At the printers front panel, select the 
 icon, and then select Substrate load > Load roll.
Alternatively, feed paper into the printer until the printer grasps it. The front panel will guide you
through the following steps.
2.Carefully insert the leading edge of the substrate above the black-ribbed roller, making sure the
substrate remains taut during the process. Avoid pulling excess substrate from the roll, which could
cause skew. Also avoid rewinding the substrate manually, unless the printer asks you to do so.
WARNING!Take care not to touch the rubber wheels on the platen while loading substrate.
These wheels can rotate and trap skin, hair or clothing.
WARNING!Take care not to push your fingers inside the printers substrate path.
The printer beeps when it detects and accepts the leading edge of the substrate.
3.Select the substrate category of the roll 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.
NOTE:The RIP substrate setting will overwrite the front panel setting.
TIP:When loading very thin or very thick substrates, you should follow the manual loading
procedure to reduce the risk of substrate jams and printhead crashes

							4.If the roll of media you are loading is new, select the length in the front panel. If the media has been
used before, and the tracking feature was used, select the media remaining. For information of the
media length tracking feature see 
Media Length Tracking Feature on page 38
5.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: select the
 icon, then select Substrate handling options > Max skew setting.
6.Wait until the substrate emerges from the printer, as shown in the following graphic.
NOTE:If you have an unexpected problem at any stage of the substrate loading process, see
the Maintenance and troubleshooting guide.
7.The printer calibrates the substrate advance.
8.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 printers side plate (as indicated by the

Load a roll into the printer (manually)
The manual loading process should be used if the media you are using is thinner of thicker than normal.
In addition this process can also be used if the media has excessive curl or the printing side of the media
faces outwards. If the media you are using is a standard type of media and in good condition, use the
automatic load process described previously, see 
Load a roll into the printer (automatically)
on page 19
To start this procedure, you need to have a roll loaded on the spindle. See

TIP:When loading very thin substrates, always select the substrate category as Banner to
minimize the vacuum pressure applied while loading; when loading very thick substrates, always
give the substrate category as HP Photorealistic to maximize the vacuum pressure. After loading
and before printing, go to the front panel and change to the correct category for the substrate you
are loading: select the 
 icon, then select View loaded substrate > Change loaded substrate.

							Unload a roll from the printer
If you used the take-up reel during printing, unload the printed roll from the take-up reel before attempting
to remove the roll from the printer. See 
Unload a roll from the take-up reel on page 34.
Check whether the other end of the roll is still attached to the input spindle, and follow the appropriate
procedure as described in the following sections.
The normal procedure (roll attached to spindle)
If the end of the roll is still attached to the spindle, use the following procedure.
1.On the printers front panel, select the 
 icon, and then select Substrate unload > Unload roll.
2.Press the OK button on the front panel as many times as needed to rewind the substrate.
3.Lift the spindle lock lever.
4.Remove the roll from the printer, pulling out the right end on the right side of the printer first. Do
not insert your fingers into the spindle supports during the removal process.
Exceptional procedure (roll detached from spindle)
Use the following procedure if the end of the roll is visible but no longer attached to the spindle:
1.If you have already selected Substrate unload at the front panel, press the Cancel button to cancel
that procedure.

							2.Lift the substrate-adjustment lever. If the front panel shows a warning about the lever, ignore it.
3.Pull out the substrate from the front of the printer.
4.Remove the empty spindle from the printer, pulling out the end on the right side of the printer first.
Do not insert your fingers into the spindle supports during the removal process.
5.Lower the substrate-adjustment lever.
6.If the front panel shows a warning message, press the OK button to clear it.
NOTE:If the end of the roll has disappeared inside the printer, use the Move substrate button on the
front panel to move it forward.
Use the take-up reel
The take-up reel must be enabled and operated from the front panel. When the take-up reel is enabled,
the “Take-up reel enabled” message appears on the Substrate tab on the front panel. If the take-up
reel is not enabled and you would like to enable it, select the 
 icon and then select Take-up reel >
Enable take-up reel.
Follow these guidelines when taping rolls to the take-up reel spindle core:
●Make sure that the substrate is straight when it is attached to the spindle core. Otherwise it skews
as it winds onto the core.
●The spindle core on the take-up reel must be the same width as the substrate that you are using.
●Check that neither side of the spindle core has end caps, and make sure the spindle core is pushed
firmly into both spindle guides.
