Using a flashlight, carefully inspect the timing strip for grease that may have attached to the timing strip. It is helpful to view the timing strip from several angles as even a small amount of grease can impact print quality.
Note: The timing strip is a clear strip located in front of the carriage drive belt.
Moisten the cotton swab with Isopropyl alcohol and carefully remove the grease from the timing strip. To prevent further spreading of grease, be careful not to touch the chassis or other areas inside the unit which may contain grease from the factory.
Note: If Isopropyl Alcohol is not available, you may use window cleaner solution.
CAUTION: Do not remove the grease on the chassis (metal rail).
她建議用棉花棒沾溶劑擦一擦。
