Black Mark Sensing

The MtP Series printers can print on preprinted forms on roll media by using a “black mark” to sense the

beginning of each form. The black mark is located on the form in a position where the printer’s paper out

sensor can be used to detect its presence. Additionally, the “LP” models are capable of sensing a black mark on

the back side of the form and for sensing the gap between labels. The recommended position for the black

mark is described below.
