  • Page 45: Saving The Label In The Labeller's Permanent Memory

    PtESt PRINTING TEST By pressing ENTER/PRINT, a test label is printed of previously selected fields, but with fixed weight values. The print test depends on the selected functioning mode: - Std mode: the first time the fields with the kg unit of measure are printed, the second time the fields with the lb unit of measure are printed, and so on.

  • Page 46: Printing The Heading

    3. For each SLAVE, follow the procedure described in the paragraph “SAVING THE LABEL IN THE LABELLER’S PERMANENT MEMORY” and then set the PC.SEL step at the original value. 9 PRINTING THE HEADING It is possible to programme from the indicator or from PC the 4 alphanumeric heading lines of 24 characters each, which will be printed in the manner which has been programmed until these are cancelled or substituted.
  • Page 47 (see section 8 for further information) Use the ZERO key to select the character height, then press ENTER to confirm 8. The instrument is ready to programme the first heading line, which consists in entering a sequence of two numeric digit codes, corresponding to the fonts (see Table 3).
  • Page 48 For example: To write “ROSSI GIUSEPPE S.R.L.”, one should set the following codes: 82 / 79 / 83 / 83 / 73 / 32 / 71 / 73 / 85 / 83 / 69 / 80 / 80 / 69 / 32 / 83 / 46 / 82 / 46 / 76 / 46 / 32 / 32 / 32 when one has finished programming the heading line, the instrument automatically passes to the programming of the following line 10.
