Handling precautions
Always observe the following handling precautions when 
replacing the consumable products:
❏ The photoconductor unit weighs 3.0 kg (6.6 lb). Be sure to hold 
it firmly by the handle when carrying it.
❏ When replacing the photoconductor unit, avoid exposing it 
to light any longer than necessary. 
❏ Be careful not to scratch the surface of the drum and belt. Also, 
avoid touching the drum, since oil from your skin may 
permanently damage its surface and affect print quality.
❏ To get the best print quality, do not store the photoconductor 
unit in an area subject to direct sunlight, dust, salty air, or 
corrosive gases (such as ammonia). Avoid locations subject to 
extreme or rapid changes in temperature or humidity. 
❏ Do not tilt the photoconductor unit.
