|The Gap Sensor is the black plastic piece that the labels are routed through as they enter the back of the|
Sato printer. It has a light purple knob at the end of it to adjust where the eyes (green indicators on top
and bottom) sit in relation to the label width.
|The eyes should be set in about the middle of the label. If set at the edge, it may have trouble telling the|
difference between the edge of the label and the gap between the labels. The next step is to peel a label off the backing right behind the printer.
|Release the print head and feed the backing with the missing label into the Gap Senso. Lock it in|
place by latching the print head. Close the lid of the printer.
|The printer should be “Offline” because you’ve had the lid open. If not, you’ll need to press the “Line”|
button until it reads "Offline Mode". With it “Offline”, you can press the “Enter” button to take you to the menu. Navigate to “Service Mode” using the arrows. It is the bottom right icon and is represented by a hammer.
|Press “Enter” once and it will take you to a screen displaying the “I-Mark” and its “Level Offset”. The|
Level Offset should be set to 15. If it isn’t, use the up and or down arrows to change it.
|Press Enter two more times and you should see the “Gap” and its “Level Offset”. The “Level Offset” should be set to 45. If it isn’t, use the up and down arrows to change it. The “Gap” number you are seeing is how many volts it is using to look through the paper. Without a label, it should read “0.2”. If it doesn’t, there is a potentiometer (pot) located internally on the control board that can be accessed through a small panel on the back side of the SATO printer.|
CAUTION: The Potentiometer has internal stops! You can only turn the potentiometer so far before encountering one of the stops. If you overpower one of the stops, the main control board in the printer will have to be replaced.
|It may be easier to do this step with the applicator slid forward, closest to the front of the machine. The|
access panel is held in place with one Phillips head screw and a small tab. Remove the screw and
pull the panel. You will see three potentiometers, and it is important not to disturb the two outside
pots. The Gap Sensor pot is the middle pot on the board. The pot is like a small knob, but you need a
small precision flat screwdriver to adjust it. Clockwise will increase voltage and counter-clockwise will
decrease it. Adjust the potentiometer until the Gap reading is 0.2 volts.
|After the Gap is set to “0.2” without a label, you can advance or reverse the label backing so the sensor|
is looking at a label this time. It should then read around “1.7” to “2.0”. If it doesn’t, confirm what the
“without a label section” says again as well as the level offset. If it still doesn’t, contact EII Customer Support. After that is set, press Enter to advance to the Slice Level setting. This needs to be set at the middle value of the readings of with and without a label.
Setting it to “1.0v” should be fine. Press Enter until you are back to the home menu screen. Navigate to the Online Mode (top left icon) using the up arrow and press Enter. Press the “Line” button to bring the printer back online.
Feed three labels to make the setting take effect.
