TROUBLESHOOTING
CONDITION SOLUTION
Less of the tab is on the top of the media than
on the bottom. Adjust the Tab Positioning Knob
counterclockwise to place more of the tab to
the top side of the media.
Tab is not flush with the edge of the media. Media is not being fed flush with the Media
Guide Fence. There should not be more than
1/8” to 1/32” space between the media and
the Media Guide Fence when the media
enters the tabber.
Check/Adjust the Registration Assembly.
When double tabbing one tab is not placed
properly on the edge of the media. 1. The media may not be traveling along
the Media Guide Fence. Adjust the
angle of the registration rollers by
turning the knob on the skew guide.
2. Check the transport pressure (media
thickness adjustment). Too much
pressure will cause the media to flex as it
is transported. Too little pressure can
cause the media to skew as the tab is
being applied.
Two or three tabs applied next to each other.
Programming issue.
When programming for multiple tabs
Together was selected instead of Separate.
Reprogram the job using Separate or use the
Auto Pos. feature.
More tabs applied then selected.
1. Wrong number of tabs selected.
2. Improper Tab sensor adjustments. Check
the V-Tab (Tab and Backing Voltage)
adjustments.
3. Tabs were not threaded correctly
(missing the Tab Web Sensor).
