Refer to the table below and choose the paper appropriate to the ribbon width. Even if the ribbon is narrower than paper, printing can be performed. However, it results in the narrower print range. LE840T/LE850T Ribbon width 68mm Appropriate paper width 45 to 63 mm 84ｍｍ 63 to 79 mm 112ｍｍ 79 to 107 mm The ribbon tension adjustment may be further required according to the ribbon width. In the case a narrower width of the ribbon is used, if the ribbon tension is strong, the ribbon will wrinkle. According to the print patterns, fine adjustment of the ribbon take-up motor is required. As a guide, regardless of the print speed, it should be set to "-3" (FW) and "-1" (BK) for 68-mm wide ribbon, and "-4" (FW) and "-2" (BK) for 50-mm wide or less ribbon, respectively. E7-9
