What basic maintenance steps should I follow to prevent injuries?

Basic maintenance procedures include: reading and understanding all instructions, observing all warning signs on the printer, unplugging the printer before cleaning, not using it near water or while wet, placing it on a stable surface, ensuring the power cable is not damaged or a trip hazard, and using only HP-supplied power cables and adapters. No internal components can be repaired by the user—servicing should be done by authorized personnel. (Page 8)
