Stamp Placement Problems
CONDITION SOLUTION
Stamps are not placed in the same place
on the media. Stamp placement should be within +/- 1/8”
1. Check the pitch setting for the stamp. It
should be 0.005 – 0.010 more than the stamp
size plus the space between the stamps.
2. Check to be sure the V-Tab adjustment is
correct for this stock.
3. Check Media Thickness Adjustment. Too little
transport pressure can cause the media to slip
when it is being fed.
4. Check/adjust media hold down guides. If they
are exerting too much pressure, the media may
slip.
5. Check to be sure the press roll, for tab drive, is
engaged. If this roller is not engage, the tab
drive roller will slip on the stamp stock.
When applied the Stamp is not aligned on
the media. 1. The media may not be traveling along the
Media Guide Fence. Adjust the angle of the
guide rollers by turning the knob on the
Registration Assembly.
2. Check/adjust media hold down guides. If they
are exerting too much pressure, the media may
skew.
3. Check Media Thickness Adjustment. Too
much pressure will cause the media to flex as it
is transported.
Two or three stamps applied with a large
space between them. Programming issue.
When using the manual tab positioning
procedure; Separate was selected instead of
Together. Reprogram the job and select
Together.
Together will place tabs together.
Separate allows different positions (offset
values) to be selected, as shown.
More than three stamps applied one after
another on the media when 1, 2 or 3
stamps are selected. Check/adjust V-Tab (Tab Voltage and Backing
Voltage) settings.
