TP 16 Stitch Identification Test Pages
The print heads work together to stitch the image together. The X-stitch and Y-stitch pages
print when the stitch identification selection is made from dC612.
Stitch identification test pages are printed from dC612.
NOTE: All test prints should be printed on A4 or 8.5 x 11 inch plain paper and long edge feed.
Use the best quality media available. Do not use hole punched paper. Failure to do this will
result in an error message being printed instead of the test page.
NOTE: When the paper selected for the test print pages is correct, the test pages will be
printed with annotations on the bottom edge confirming the test print name, the LEF status and
that double chevrons will be printed if the paper used is A4. The chevrons indicate the stitch
position between print heads.
Purpose
The X-stitch and Y-stitch pages indicate the accuracy of print head alignment. Refer to Figure
1.
NOTE: The X-Stitch print is made up of an interference pattern. The degree of an x-stitch issue
is highly exaggerated on this print. The actual x-stitch error will appear less pronounced on a
customer image. If in doubt about the severity of an x-stitch issue print a customer image to
determine if it is visible.
To solve image quality problems associated with stitch errors, refer to IQ 5, IQ 9 and IQ 13.
