6.4.4 Image Centering
Centering establishes x- and y-offset values. The x offset determines when a Print Head
lowers and raises, between which printing occurs. The y offset determines which group of
Print Head elements produce images.
If the Print Head lowers too soon, the leading card edge (in encountering an already
lowered Print Head) can shear the ribbon. Another ribbon shear condition can occur if the
Print Head remains lowered past the trailing edge of the card, where the head can abruptly
drop below card level. Centering should be checked by printing a full-bleed image.
Proceed as follows:
Step 1. From the Window’s print driver, or Test software issue the “Print Test Card”
command (A). Note that the resulting printed card includes x- and y-offset values
(e.g., Offset X - Y 008-006.
Step 2. Create and print a full-bleed image using a suitable graphic application and
the Eltron-provided Window’s print driver).
Step 3. Check for the conditions below.
