6 Check the print head and platen for adhered label stock.
7 If there is label stock on the print head, use isopropyl alcohol to clean the heater element
surface. Verify that all label stock, media residue, and any other contaminants are clear from
the print head.
8 If label stock is wrapped around the platen, rotate the platen and find a loose end of the stock.
Grip the stock firmly and pull it free from the platen.
DO NOT USE a sharp blade to cut stock from the platen.
9 If label stock still remains on the platen, clean the platen surface using Bloch Buster, window
cleaner, a damp cloth/paper towel, or Fedron. Verify that all label stock, media residue, and any
other contaminants are clear from the platen.
10 Although the stock guides are very short, check both right and left sides for any label stock that
may have adhered to them. Use isopropyl alcohol to clean these areas.
11 Verify that stock-related contaminants are not blocking the Top of Form (TOF) sensor in the
left stock guide. Use canned air to clear sensor if necessary.
12 Verify that stock-related contaminants are not blocking the Present Sensor (PS) at the exit point
of the unit. Use canned air to clear sensor if necessary.
13 Check the ESD static brush for any label stock and related contaminants. Carefully remove
these contaminants.
Note: DO NOT USE alcohol or other chemicals to clean ESD static brush. If the brush is
damaged, replace the brush and/or unit immediately. Operating the unit without an ESD static
brush, or with a damaged brush, may result in reduced print head life.
