Cleaning
QL-300 User Guide 357
* Clean the feed path (including rollers) and fuser unit when changing the width of the roll paper.
Streaks may appear when printing, particularly after changing the paper width from narrow to
wide, because of the traces (paper dust etc.) left along the width of the paper.
When you change the width of the roll paper, check the conditions of the fuser unit and feed
path and clean them, and then restart printing.
