●[Precautions on printing close to print target]
When the printing is made close to the print target, it is possible for the printhead cover to get stained inside
and outside by the ink splash bounced back from the print target. In order to avoid the print errors caused
by the stains, please ask the customer to watch the stains on the printhead and clean the printhead
periodically as needed.
