On the NC model units the Paper Roll is advanced after each shot and between stages during a competition. By doing so a "clean aiming bull" is presented to the camera for scoring of the next shot. The Paper Roll does have to be replaced periodically.
How Often Should Paper Roll be Replaced?
The answer to how often an Paper Roll needs to be replaced is, "it depends." In general a Paper Roll will last between 1500 and 2000 shots.
•In competition mode the paper strip is advanced 26mm after each shot, thus will not last as long in practice mode.
•In practice mode the paper strip is advanced 16mm, and will last longer than in competition mode.
Measuring How Many Shots are Left on a Paper Roll
As the paper roll is depleted a good rule of thumb for knowing how many shots a roll has left is to measure the thickness.
•Each 1mm of thickness is about 25 shots in competition mode, or about 40 shots in practice mode.
•A 60 shot course of fire (e.g. 3x20) will require about 4mm of thickness in competition mode, or about 3mm of thickness in practice mode.
Steps to Replace the Paper Roll
1.Put the Target into "Maintenance Mode." Maintenance Mode prevents the Target from scoring any false positive shots (shot's that are not real). If the Target is left in "Scoring Mode" and you physically interact with the Target it could (and likely to) score shots that are not really there.
Athena for Club customers can put a Target into Maintenance Mode by opening the "Athena Unit Maintenance" window, check the appropriate Targets, and click the Maintenance Mode button.
Athena at Home customers can put a Target into Maintenance Mode from the paired Monitor. From the main screen on the Monitor, select Menu -> Advanced -> Maintenance. Then on the left hand side, select the button next to Maintenance Mode.
2.On the Target, flip open the right and left side Locking Cams that help hold the aiming masks in place.
3.Remove the used Front Aiming Mask.
4.Using either an precision knife (e.g. X-Acto Knife) or scissors, cut the paper strip near the bottom of the frame. Leaving a clean edge on the paper strip will make it easier to seed in step X. Pull the paper strip up and roll the remainder onto the roll.
5.Gently pull the two roller guides on either side of the paper roll out, with it, remove the paper roll.
6.Replace with a new Paper Roll. Note, the two black plastic pieces in the center of the roll, should be discarded.
7.Inspect the Back Aiming Mask and replace if needed.
8.With the Back Aiming Mask in place, feed the paper strip through the top and bottom of the frame.
On the back of the Target turn on the paper strip motor. This is the top most on/off switch (the bottom on/off switch is the Target's power).
Once the paper strip catches the roller, is snug, and advances just beyond the blade at the bottom of the target, turn off the motor.
To prevent the paper from curling back in on itself, place a large binder clip on the strip, just below the blade.
9.Insert a clean Front Aiming Mask. The side of the mask with the square black alignment shape should face the athlete. The Mask should seed easily with a little finesses. The text at the bottom of the mask should seed just above the bottom of the frame.
10.Flip down the right and left side Locking Cams.
11.On the back of the target run the Camera Alignment process.
On NC models with a single button interface, firmly press the button to start the Camera Alignment process.
On NC models with a four button interface, press the select button (the right most button).
a.When the Camera Alignment process runs the Red X and Green O lights both turn on. After a few seconds the Red X or Green O (but not both) will flash. The flashing Green O represents a success, and flashing Red X represents an error.
b.If the Red X flashes, check that the alignment shape is clearly seen, and you have the right size aiming mask loaded.
12.Return the Target to Scoring Mode.
Athena for Club customers can put a Target into Scoring Mode by opening the "Athena Unit Maintenance" window, check the appropriate Targets, and click the Scoring Mode button.
Athena at Home customers can put a Target into Maintenance Mode from the paired Monitor. From the main screen on the Monitor, select Menu -> Advanced -> Maintenance. Then on the left hand side, select the button next to Maintenance Mode.
Wash Your Hands
After performing any maintenance operation on any NC Unit, which will contain lead dust, wash your hands with soap and water before returning to work or training.
