To clean the printhead and platen roller, complete these steps:
1. Open the printhead assembly.
2. Remove the media.
3. Using the swab from the Preventive Maintenance Kit (part number 47362), wipe along the
brown strip on the printhead assembly from end to end. In place of the Preventive
Maintenance Kit, you may use a clean swab dipped in a solution of isopropyl alcohol
(minimum 90%) and deionized water (maximum 10%). Allow the solvent to evaporate.
Caution • The printhead may be hot and could cause severe burns. Allow the printhead
to cool.
Caution • Before touching the printhead assembly, discharge any built-up static electricity
by touching the metal printer frame or by using an antistatic wriststrap and mat.
