							NOTE:If you want 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 m (3
feet) of substrate.
Load a roll onto the take-up reel
1.On the printers front panel, select the  icon, and then select Substrate load > Load take-up
reel.
2.If you want to load the take-up reel now, select Load take-up reel now on the front panel. If you
want to load the take-up reel during printing, select Load it during printing on the front panel.
NOTE:DO NOT use skip check if the skew is above 3 mm/m.
3.Make sure that the loading table is in its upright position.
4.Unlock the take-up reel spindle by pushing the spindle lever to its uppermost position.

6.Remove the blue stop from the spindle.
7.Load the core onto the take-up reel spindle.
8.Replace the blue stop on the spindle.

							9.Load the take-up reel spindle into the printer by pushing firmly on both ends of the spindle.
10.Press the OK button on the front panel, and then select a winding direction.
The printer advances the substrate. Make sure that the substrate passes in front of the loading
table, as shown.

							11.It is critical to the correct media loading onto the take up reel that the media is correctly aligned
with the blue stop and right spindle hub, especially for long print runs. Check that the media is
hanging centered between the blue stop and the right spindle hub.
12.Check that the right edge of the substrate is aligned with the right spindle hub, there must be no
space at the point shown between the two green arrows.
13.If it is not aligned, loosen the blue stop and the right spindle hub and align with the media edges.
If the core you are using is wider than the media, ensure that is centered, allowing an equal gap
on both sides.

							14.Ensure that once the media is correctly aligned with the blue stop and the right spindle hub, they
are both locked in position. Shown below is the media correctly aligned with the blue stop and the
right spindle hub.
15.Pull the substrate taut to the position shown in the following figure. Do not attempt to pull more
substrate out of the printer. Use tape to secure the substrate to the spindle core, taping it in the
center first. You may need to use more tape than is shown in the following image. The substrate
should be secure enough to support the weight of the loop-shaping core, which you insert in a later
step.
NOTE:If you are loading the take-up reel during printing you do not need to pull the substrate
taut. Tape the substrate to the spindle core when an adequate length of substrate has fed from the
printer after printing begins.
NOTE:To avoid having the substrate skew as it winds onto the spindle core, make sure the
substrate is straight when you attach it, and aligned with the input roll. It is sometimes useful to use
the core grooves to align the substrate.
16.Press the OK button on the front panel. The printer advances the substrate.

							17.Assemble a loop-shaping core by matching the shape-coded and color-coded lengths of plastic
tubing. The loop-shaping core must be the same width as the substrate that you are using. Make
sure that both end caps are firmly fitted on the ends of the loop-shaping core.
NOTE:The front-panel display shows the required length of the loop-shaping core based on the
width of the roll that you have loaded into the printer.
18.Gently lower the loading table, to avoid wrinkles and improve winding.
19.Carefully insert the loop-shaping core.
NOTE:Make sure that you insert the loop-shaping core. The take-up reel will not function
correctly without it. The loop-shaping core must have end caps. Make sure that the end caps extend
over the edges of the substrate.

							20.Use the wind-direction switch on the take-up reel motor to select the winding direction. 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 front panel shows you the correct setting based on the winding-direction decision you made
in step 7.
21.Press the OK button on the front panel. The Take-up reel has been successfully installed
message appears.
22.The following image shows how the printer looks when it is operating. As substrate is fed from the
printer, it drops down in a loop and then up into the take-up reel spindle.
NOTE:While the take-up reel is operating, make sure that the take-up reel sensors are not blocked.
NOTE:The cutter is disabled when the take-up reel is in use.
NOTE:If you want to move the printer, first remove the take-up reel sensor and cable housing unit
from the foot of the printer stand. Place the sensor and cable housing unit on the printer stand crossbar
and use the blue plastic screw to affix the housing unit to the leg of the stand, as shown, while the printer
is being moved. When reinstalling the housing unit, make sure that the wheel on the foot of the printer
stand is pointing forward.

							Unload a roll from the take-up reel
1.On the printers front panel, select the  icon, and then select Substrate unload > Unload roll.
The printer advances the substrate to allow for cutting.
2.Lift the loading table to its upright position.
3.Switch the wind-direction switch to the Off position. The switch is in the off position when it is
centered (in other words, when the switch is neither in position 1 nor position 2).
4.Remove the loop-shaping core.

							5.Use the winding button on the take-up reel motor to wind the excess substrate around the take-up
reel spindle.
6.Press the OK button on the front panel.
7.Use the winding button on the take-up reel motor to wind the remainder of the substrate around
the take-up reel spindle.
8.Press the OK button on the front panel.
The amount of printed substrate that is on the take-up reel spindle appears on the front panel.
9.Unlock the take-up reel spindle by pushing the spindle lever to its uppermost position.

							10.Remove the roll 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.
11.To remove the roll from the printer after you have unloaded the take-up reel, see Unload a roll from
the printer on page 25.
Loading textile types of media
The following steps show you how to load a textile type of media into the printer by using a secondary
section of media as backing.
1.Select a piece of paper of a similar width of the paper and around 500 mm length, polyester
materials (Backlits) are the best ones for wider medias due to it stiffness
