Chapter3 Handling Recommended Module Values Print directions of a barcode are as shown below. The recommended module values vary by paper type, barcode type, and the print direction. Paper width direction Paper width direction Paper feed direction Paper feed direction Fence barcode Ladder barcode If [Rotation Settings] is set to [Normal] or [Rotate 270 Degrees], the barcode is not be printed. CAUTION ❏ When the minimum module size is in units of 300 dpi U Page 104 ❏ When the minimum module size is in units of 600 dpi U Page 105 • Readability of a barcode varies by paper type, performance of a barcode reader, or other factors.
Furthermore, drop in print quality due to clogging of print head nozzles or skew of ink drops can cause a barcode to become unreadable. In case it happens, it is recommended to print HRI characters or take other measures. • Due to the characteristics of the ink, printing a barcode onto paper which ink has seeped into may cause the bar width of the barcode to become thicker, impacting the barcode rank. Reducing the bar width of the barcode may improve the barcode rank. When using a built-in barcode font, use the [Bar Width Adjustment] function to perform adjustments.
• If vibrations or shocks are applied to the printer during transporting or installing the printer, it may cause drop in barcode rank. In that happens, barcode rank may improve by carrying out [Bi-directional Printing Adjustment]. ( "Vertical Alignment" on page 212 ) 103
