CHAPTER 6

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.

Result	Remedy
Image Centered on Card	None; Skip Remaining Steps
Ribbon Sheared (No Image), or Excessive Border at Trailing Edge	Increase x Offset
Excessive Border at Leading Card Edge; Ribbon Shear Possible	Decrease x Offset
Excessive Border at Card Edge Nearer Front of Printer.	Increase y Offset
Excessive Border at Card Edge Nearer Back of Printer.	Decrease y Offset

Probable starting points for Offsets are at or near:

X-offset = 0

Y-offset = 0
