WEBBING THE L60
1. Turn off the Main Power switch (22) on the Front Panel
2. Loosen the black thumbscrew (19).
3. Slide off the removable label retainer (20).
4. Place a roll of labels on the Unwind Hub (01).
5. Loosen the Socket Head Cap Screw (02) on the Clamp of the Unwind
Backing Disc (03) and position the roll of labels so the labels track centered
on the Vacuum Head (06) when peeled off (See FRONT VIEW). (NOTE: For
round or oval labels, it is important that the Star Wheel (05) be on the
centerline of the label).
6. NOTE: If the unit is equipped with photoelectric label sensing or a clear label
sensor, the position of the sensor relative to the label is not critical in most
cases. The clear label sensor detects the difference in thickness from the
label to the backing material. Metalized graphics or alphanumeric characters
will cause this sensor to false trigger. Locate the sensor away from the path
of metalized material. (See SIDE VIEW PHOTO SENSOR)
7. Replace the removable label retainer (20) and tighten thumbscrew (19).
8. Pull the web over the Brake Arm (06) and down between the Web Guides
(07) on the Label Guide Support Plate (08). (NOTE: If equipped with
photoelectric sensor, slide web between white idler roller and web drag (21).
9. Adjust the Web Guides (07), so the web is held with minimum side play but
still moves freely.
