To ensure that the mail being labeled registers properly against the side guide, ensure that
the feeding system transfers material onto the Tabber tabletop or third party equipment’s
tabletop such that its entire edge makes contact with the material side guide being used to
register material with no resulting skew. The concept is illustrated in figure
Figure 3-7
.

3.3.2 The Tabber Skidbar Assembly
The Skidbar Assembly (p/n 330740A) is used to apply sufficient pressure onto conveyed
mail and magazine substrates. It helps to register substrates against the Left and Right
Side Guides by forcing the material to make proper contact with the directionally biased
transport belts. This means that the belts will move material from the center of the
tabletop towards one of the two side guides depending on whether operator side or non-
operator side labeling is desired. If there is insufficient pressure along the entire length of
the Skidbar Assembly, it is possible that the substrate can skew in an undesirable direction
resulting in poor label positioning accuracy. A side view of the Tabber Skidbar Assembly
is illustrated in
Figure 3-8
as a reference. During setup of a job, it is important that the
spacing between the tabletop and the ball bearings installed in the Tabber Skidbar
Assembly is consistent along its entire length. If the ball bearings are closer to the
tabletop at one end of the transport (say the upstream side) and higher at the other end, the
material being conveyed will not be properly transferred to the label application and
