Adjustment methods
Adjusting media feeding: Media advance adjustment
The media feeding operation can be adjusted depending on media characteristics, such as thickness, rigidness, and
smoothness of the surface.
To maintain a high print quality, perform media advance adjustment and set the most suitable media advance
adjustment value.
What is the timing to perform media advance adjustment?
When one of the following parameters has changed.
- The media has been changed
- The print mode has been changed
- The position of the pressure roller lever has been changed
- The TUR unit usage setting or TUR mode (loose or tension) has been changed
- The media advance mode has been changed
- The suction fan setting (low, medium, high) has been changed
When the media advance adjustment value is incorrect.
When the media advance adjustment value is incorrect, banding (horizontal bands) appears periodically on the
printout.
Two modes are available to adjust media advance:
automatic print adjustment
and
manual print adjustment
.
With automatic print adjustment, the printer prints an adjustment pattern, check the result with sensors, and set a
media advance adjustment value automatically.
With manual print adjustment, the printer prints an adjustment pattern, then the user selects visually a media
advance adjustment value and set the value on the printer.
