Banding at variable extreme environmental conditions
The Accuracy Calibration has been done at normal environmental 
conditions, therefore printing in extreme environmental conditions 
will cause banding because the advance of the Drive Roller does not 
correspond to the same conditions that the calibration was done in. 
To solve the problem, try the following:
n
Perform the Accuracy Calibration in the new environmental 
conditions (Refer to the User’s Guide - Media Solutions).
Banding with unsupported Media
The Accuracy Calibration has not been done for the Media now 
loaded. Banding may occur because the advance of the Drive Roller 
does not correspond to the same conditions that the calibration was 
done in. To solve the problem, try the following:
n
Select the Media loaded in the “Media Options” menu and 
perform the Accuracy Calibration (Refer to the User’s Guide - 
Media Solutions).
Banding due to Ink Cartridge replacement while 
printing
A user has removed the Ink Cartridge while the Printer was printing, 
which has caused the Printer to stop. If the user does not replace the 
Ink Cartridge immediately, when the Printer starts to print again, a 
band will appear in the position where the printing restarted. This is 
because the wet ink interacts with the dried ink on the media 
causing the band to appear. To solve the problem, try the following:
n
Do NOT remove the Ink Cartridge while the Printer is Printing. 
Only replace/remove Ink Cartridges in between Prints.
n
If the Ink Cartridge was replaced due to the “Empty” status on the 
Front Panel, then advise the customer to replace the Ink Cartridge 
when the “Very Low” status is showing on the Front Panel.
