Published: December 3, 2011

UPDATED 12/19/2018

If you experience tabbing problems on the Accufast KT, tune the sensor for clear tabs – translucent tabs Also known as a KT Sensor Reset:

WARNING
DO NOT PLACE FINGERS OR TOOLS BETWEEN
OR NEAR MOVING PARTS.

1) Turn the POWER SWITCH off.
2) Remove any tabs and debris from the peel point area through the INSPECTION WINDOW on the input end, below the threading path.

CAUTION
IF ALL TABS AND DEBRIS ARE NOT REMOVED
FROM THE PEEL POINT AREA BEFORE CLEAR
TAB IS ACTIVATED, THE SENSOR’S DEFINITION
OF CLEAR TABS WILL CHANGE AND CLEAR
TABBING WILL BE PREVENTED.

On the product entry side, there is an elongated hole under where the tabs peel off, see below

If you look inside the hole, you will see the bottom portion of the sensor.  (The black circle in the white plastic, see photo below) Accufast Photo Sensor, 05-0559-00
Clean it off with some compressed air that is rated for sensors and electronics.
Also, make sure no tabs are anywhere in the path.

Once you have this area clean turn the KT back on and,

 

3) Toggle CLEAR TAB off and wait, a few seconds
4) Toggle CLEAR TAB on.
5) Toggle ON/OFF until a tab advances to the peel point and the TAB READY light illuminates. Your sensor has now been re-calibrated! Another thing to check is to make sure the tabs are threaded correctly!
