EPSON — Recommended Module Values

Chapter3 Handling • 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].
