What kind of media can be used on this printer?

Answer: See details about this in the following manual.

Basically you can use all kinds of media if it is under the certain conditions which you can see on a list in the manual above.
Even if your media is out of the condition list, you may be able to use it if it can clear the all print steps.

What is the “All print steps”?
① Media set
The media paper core can be fixed by media holder.
② Media feeding
The media has to be fed straight by media feeding unit, and there are no wrinkles on the media surface while it feeds.
③ Attach it on the feeding belt
The media surface has to be flat and not wrinkled or curved edge after it pressed on the feeding belt by pressure roller.
④ Print
The media has to be print with the head gap 3.0mm (≒0.118inch) or less, and also the print head carriage does not hit to the media.
See more details in the other Q&A [How much the head height is required? ]
⑤ Take up media
The media has to be taken up straight by media feeding unit. It can not be skewed while it is taking up.
   
However, the ink bleeding and color will be different between media, because it depends on the type of “material”, “pretreatment”, “after treatment”. So we recommend you to make some samples to see the print result first, before you make any productions.
