Figure 14: Printhead cleaning with ribbon removed
Printhead Cleaning Procedure
• If tray is in, press Tray Button to extend tray
• Remove the top cover by carefully lifting and pulling forward. Set the cover aside.
• Open printer chassis by pulling chassis release knob and lifting chassis up by chassis
handle.
• Remove Ribbon Supply Roller from printer and place on CD Tray, this will expose
the printhead. (As an alternative, remove ribbon completely from printer)
• Printhead is now visible from the inside of Printer chassis
• Move the Supply Ribbon roller and ribbon forward and away from the front of the
unit, exposing the printhead.
• Use a cotton swab or Q-tip with a few drops of isopropyl alcohol to gently rub the
printing surface of the print head.
• Use a sweeping motion starting from one end of the printhead and move past the
other end to remove any dust particles (do not lift up Q-tip in middle of printhead
since that may leave residue in that area).
• Allow the printhead a minute to dry before moving ribbon spindle back on to chassis.
• Printer will wind slack ribbon at power ON, or pressing Start and Tray button
simultaneously will also wind slack ribbon.
