You should clean the media guides and media path regularly to keep debris off the
media surface and printhead where irregularities can spoil print quality or damage the
printhead. Cleaning the guides also prevents the media from skewing or improperly
tracking as it travels through the paper path which can result in smeared images and
print off the side of the label. Always clean the media guides immediately after a label
jam in the printer.
To clean the media guides and media path
1. Turn the On/Off switch to the off position and remove the power cord.
2. Remove the media cover.
3. Remove the media and ribbon (if necessary).
4. Pull down on the lower media guide to open up the media path.
5. Use the cloth moistened with isopropyl alcohol to clean the upper and lower media
guides. Be sure to remove all traces of debris. Release the lower media guide.
6. Remove all traces of dust, paper, and adhesive from the media path with a soft
bristle brush or vacuum.
7. Replace the media and ribbon.
8. If you are finished cleaning, replace the media cover.
