Printhead Life Extension

information is useful and applicable for the 676 series printers.

Matching stock and ink widths

If your customer is running multiple media and multiple widths on their AVERY DENNISON machine, Great!
They are taking advantage of one the most compelling features of our printers: multimedia capability. Our
printers can also reduce the width of the ink to only that area being printed. However, we run into printhead
problems when customers combine both these features.
The edge of the narrower stock not covered by the ink will gouge the printhead and cause dots to be
out.
Here, the customer will have
much shorter printhead life
because of the edge of the
narrower, uncovered stock.

WRONG!

The solution is to make sure
that the narrower stocks
have at least 1/8” of ink
coverage over the edge.
The widest stock does not
need full ink coverage.

RIGHT!

This edge which is
not covered by ink
will erode the
printhead. Will have missing dots from
the eroded printhead when
this prints out.
Printhead
Must have 1/8" inch
overlap to protect the
printhead from the
stock edges
Overlap unneccessary because
this is the widest stock being
printed
