5.4 Avoiding Loss of Material
!
Attention!
Loss of material!
The print images for the upper and the lower side of one label/section are printed at two different places in
the media feed.
Therefore every interruption of the continuos print process has the following consequences :
• Material already printed at the lower side will be fed to the upper printhead to complete the print of the
label/section, but the following media will not be printed at the lower side.
• A media backfeed to the lower printhead is not allowed due to the reliability of the media transport.
• Following blank sections in the media strip are generated, which cannot be used.
• For structured media where the print image has to be synchronized to the media transport the loss of
material can reach a length of more than 300 mm.
To minimize the loss of material it is necessary to avoid interruptions of the continuos print process.
 Interrupt the print process with the pause key only if it is absolute necessary.
 Avoid print jobs with a small amount of labels/sections, especially single prints.
 Avoid predictable error situations  5.7 on page 19.
If errors occur the loss of material is particular high. Besides the blank section also material must be
rejected which is partly printed.
Optimization of the Data Transfer
If sequent labels/sections contain differing information, the internal preparation of the second sections must be
completed before the printing by the lower printhead for the first section has been finished !
Otherwise the first section will be fed to the upper printhead to complete the print without printing the next section at the
lower side. The print of the second section begins only after completion of the first section.
Therefore it is necessary to minimize the data to be transferred. i.e. to avoid transferring complete label descriptions and
to transfer the changing data only :
 In the printer driver menu General > Print Settings > Advanced Setup > Options the setting "Force optimized
printing" is permanently activated.
!
Attention!
Loss of material!
The RS232 interface is unsuitable for fast transmission of changing data.
 Use USB or Ethernet interface for print operation.
