Printed Barcode Cannot Be Read
Are you using a small barcode or a barcode consisting of thick lines?
●
Enlarge the barcode.
●
If the direction of lines in the barcode is perpendicular to the paper output direction, turn the image 90
degrees to make the lines parallel to the paper output direction.
●
If the problem persists even after performing the above operation, change the mode by using [Barcode
Adjustment Mode]. The improvement effect is weakest with [Mode 1] and strongest with [Mode 3]. Try the
adjustment starting with [Mode 1].
Setting in the Printer Driver
[Finishing] tab [Advanced Settings] [Barcode Adjustment Mode] Select the mode
Specifying Settings in the Setting Menu of the Operation Panel
Barcode Adjustment Mode(P. 680)
●
Print density will be lighter when you select stronger improvement.
●
When printing from the computer, the setting in the printer driver takes precedence. When the setting of
[Graphics Mode] in the printer driver is changed to [UFR II Mode] and [Barcode Adjustment Mode] is
changed to [Printer Default], the setting in the operation panel takes precedence.
●
When you set [Barcode Adjustment Mode] to one of [Mode 1] to [Mode 3], [Special Print Adjustment A] is
automatically set to [Off].
