Appendix C

Printhead Life Extension

NOTE: This section was written specifically for the 636 / 656 – but the 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!

This edge which is not covered by ink will erode the printhead.

Printhead

Will have missing dots from the eroded printhead when this prints out.

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!

Must have 1/8" inch overlap to protect the printhead from the stock edges

Printhead

Overlap unneccessary because this is the widest stock being printed
