  • Page 29 Figure 4-21 PRE Upper Cover − Paper roll loading space. Make sure to reserve enough space to load the paper roll. − Paper retraction space. The presenter module waits for the user to take the paper away. If the user does not take the paper, the paper backs into a collection bin. A paper retraction outlet should be added to your design if the printer will utilize paper retraction.
  • Page 30 − Paper roll space Allow space for the paper roll. There is a blue line in the space. If paper feeding is controlled above the blue line, your printer is considered to be horizontal, otherwise, it is vertical. For a horizontal installation, you need to control the paper roll above the space, mainly in order to use the buffer mechanism of the print mechanism to avoid compression.
