Load Media into the Printer (1)

Make sure the unit is turned OFF while loading media. Make sure there is
plenty of slack in the media before loading the printer. Turn ON the
unwinder after this step.

Load Media into the Printer (2)
Figure 15
Open the printer lid and adjust the guides to the media width. Then slide the media into
the guides all the way to the back until it touches the media pick wheel.
Make sure the guides are snug around the media. Make sure there is plenty of slack in
the media and that the unwinder is ON.
12

Adjust Unwinder Position
Loosen the smaller locking screw and adjust UNWINDER position using the larger
alignment screw to center paper path in printer as needed. (Leave the printer lid up
for now so you can see the media.) Retighten the locking screw when done.

Adjust Rewinder Position
Adjust REWINDER position to center the paper path that is feeding out of the printer.
NOTE: Jog the media through the printer all the way to the rewinder core to “web up”
the rewinder before printing. Experienced users will be able to perform media webbing
during printing by using a “slow initial print” option.

Because the Ready Position turns the motors off, now is a good time to
turn on the rewinder power. Keep the arm up to keep the unit OFF.

Prepare Rewinder Core
Figure 21
Place double-sided tape at top of Rewinder Flange as shown. Or use single-sided tape
when attaching media.
16

Add Star Wheels to Rewinder Arm
Place 2-4 Star Wheels (N) on the rewinder arm. Space the star wheels so that they are
centered on the media and 1-2 inches apart.
The star wheels will protect the rewinder arm from collecting any ink that has not
completely dried.

Paste Printed Media to Rewinder Core

After jogging the media through the printer (or as media comes out of printer
during a print), weave the media under Rewinder Tension Arm and tape to core.

Release Rewinder Tension Arm
Figure 24
Once the media is secure, slowly release Rewinder Tension Arm from Ready Position
so that it falls onto the media. You will see the rewinder turn. Readjust Rewinder
position if needed (see page 15).
WARNING: Treat the rewinder arm with care, yanking or tugging on the rewinder arm
can cause it to become uncalibrated.
19

Prepare to Print
✓ Make sure all equipment has power and is aligned.
✓ Close all printer doors.
✓ Remove any cut sheet paper from the printer drawer, as this can press up
and cause drag on the continuous media.
✓ Jog the media through the printer to help check alignment.
✓ See NeuraLabel 300x User Guide for proper driver setup and printing
guidelines.
✓ See our Tips and Tricks on the next pages for valuable best practices
information.

Tips and Tricks for Printing on the 300x ST
The Media and Core Width
Sometimes the width of the media and the width of the receiving core do not match. This can lead to work
flow issues.
If the rewinder core is a little too narrow.
Before placing the media on the unwinder, place the core on the rewinder and tighten up. Then see if the
media roll slides down within the rewinder flanges. If too tight readjust the rewinder outer flange spacing
to match the media roll.
If the rewinder core is a little too wide.
Web up the media as usual. The printed roll may not be a neat when the core is slightly too large.
Centering the Label Image
There are tools in the printer and driver to center the label image in both the continuous and non-continuous
media direction. Check these after the printer and roll systems are aligned.
Guides: Make sure the print guides are as snug as possible. This keeps the media straight in the non-
continuous direction.
Driver Settings: Make sure Mark Adjust has been set correctly in the printer driver. This places the label
correctly in the continuous direction.
Image Registration: Adjust the image placement using the printer’s web interface or through NeuraLabel’s
Tooxbox application. See the User Guide for further information.

Tips and Tricks for Printing on the 300x ST
The Printed Label Image
The NeuraLabel 300x ST includes the integrated unwinder and rewinder. These systems have been designed to
work well with the 300x ST and are normally required for straight through printing. If there is external drag on
the printing system, jagged edges can occur within the print.
Unwinder: The unwinder must deliver the media with no tension. Make sure that the unwinder is running
smoothly and that the media is not catching on the unwinder arm.
Rewinder: The rewinder must have a steady tension as it winds the printed media. Make sure the
rewinder is operating at a speed that matches the print speed. (Adjust one or the other.)
Cut Sheet Paper Drawer: Paper in the cut sheet drawer and press up and cause drag on the continuous
media while it prints. Remove cut sheet media from drawer during continuous printing.
Media: Very thick and very stiff medias are not compatible with the 300x ST printer. Sometimes the media
gap can catch on the unwinder arm or snag inside the printer. If you are uncertain, send a media sample to
NeuraLabel for evaluation.
Printer Cleaning
The 300x printer may need periodic cleaning of its printhead. If there are white streaks on the printed label,
run printhead cleaning. This can happen if label material scrapes against the printhead during printing.
Setup->Tools->Clean Printhead: Flushes the printhead removing label debri.

Tips and Tricks for Printing on the 300x ST
Tight Printed Media Rolls
The following are tips for getting tightly wound printed media rolls on the 300x ST.
Print Speed: Media rolls will be tightest at slower printing speed. Try slowing down the maximum
printer speed (found in the printer driver). Printing in “Best” mode also slows down the print speed
while producing the best quality print.
Flanges: If the flanges are too tight or crooked, the media may catch and not correctly wind onto the
rewinder. Make sure flanges are straight and set at the best width.
Flanges: The flanges over time may also collect media glue. If they become dirty and sticky the media
may stick to the sides, resulting in loose rolls. Periodically clean the inside of the flanges with an alcohol
wipe if this is a problem.
Rewinder Speed: If the rewinder seems to be running too slow, turn up the rewinder speed. There is a
knob located on the far side of the rewinder. Set this speed to max if printing at faster print speeds.
Core Tightness: If the core is not tightened down on the rewinder hub, it can spin resulting in loose rolls.
This might be because you did not tighten it. Or it could be because you are using an oversized core
which will not tighten well.
Media Edge Dirty: Sometimes the edge of a media roll has a collection of glue and dirt. Be sure to
remove this from the media so that you do not run dirt and glue through the printer. This glue can also
cause the media to stick to both the unwinder and rewinder and cause poor performance.
