2.3 Customized value The customized value is set with command and Memory switch setting utility. Table 2-9 Types of the Customized Value Function Selection of print density Selection of print speed Number of head energizing Selection of print control Selection of black-color density in two-color printing Value 70% - 130% (13 levels in 5% each) Level 1-9 (9 levels) One-part energizing, Two-part energizing, Four-part energizing, or Auto energizing Single-color control / Two-color control Light / Medium / Dark Note: Print speed is controlled depending on the number of the head energizing. The maximum print speed (200 mm/s) can be performed only when one-part energizing or auto-energizing is selected. In the power saving mode, all settings are ignored. 2.4 Adjusting the Roll Paper Near-End Detector Below are two situations where a roll paper NE detector adjustment is required. ❏ To adjust the detection position to suit the diameter of the roll paper core used. ❏ To adjust the detection position of remaining amount of paper. Note: Since roll paper cores vary slightly in shape, depending on paper roll design and manufacturing tolerances, it impossible to detect the remaining paper exactly. Use roll paper with a core inner diameter of 12 mm {0.47"} and outer diameter of 18 mm {0.71"} so that the NE detector can detect the remaining paper as accurately as possible. Follow the procedure below to adjust the roll paper NE detector position. 1. Open the roll paper cover, and remove the roll paper. 2-6 Setup Rev. A
