The photosensitive drum

1: first with dry absorbent cotton cloth, if bonded carbon, available isopropanol or anhydrous alcohol cleaning ( in one direction ).

2: the charging roller with a clean cotton to wipe (not to cannot but, do not use solvent ).

3 magnetic roller: use a clean cotton gently wipe ( don't scratch the surface ).

4 powder bin: gas blown clean ( dry compressed air or by washing ear ball blowing ).

5 other: general cleaning, a little attention to clean several electric contacts.

The first powder please note, HP cartridges in a magnetic roll driving part is coated with lubricating oil, be careful not to dip into the magnetic roller coating surface, it will affect the print quality, pay attention to big scraper rubber sheet not clear too clean, or mounted on the photoreceptor drum will turn dynamic, if placed in the photosensitive drum before, on a photosensitive drum and blade surface lightly coated with a layer of coating can rotate, wish you smooth powder!
