Page 8: Safety Warning
High voltages and lasers inside this product are dangerous. This printer should only be serviced by a qualiﬁed service technician. (2) Use only Dell replacement parts There are no user serviceable parts inside the printer. Do not make any unauthorized changes or additions to the printer, these could cause the printer to malfunction and create electric shock or ﬁre haz-...
Page 9: Caution For Safety
Take care not to cut or damage the power cable or plugs when moving the machine. (9) Use caution during thunder or lightening storms. Dell recommend that this machine be disconnected from the power source when such weather conditions are expected. Do not touch the machine or the power cord if it is still connected to the wall socket in these weather conditions.
Page 10: Handling Precautions
1.2.4 Assembly / Disassembly Precautions Replace parts carefully, always use Dell parts. Take care to note the exact location of parts and also cable routing before dismantling any part of the machine. Ensure all parts and cables are replaced correctly.
Page 11: Disregarding This Warning May Cause Bodily Injury
(4) Ensure the printer is installed safely. The printer weighs 23.34 lbs (Dell 1133) / 25.44 lbs (Dell 1133n), ensure the printer is installed on a level surface, capable of supporting its weight. Failure to do so could cause the printer to tip or fall possibly causing personal injury or damaging the printer.
Page 12: Esd Precautions
Precautions 1.3 ESD Precautions Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called “Electrostatically Sensitive (ES) Devices” or ESDs. Examples of typical ESDs are: integrated circuits, some ﬁeld effect transistors, and semiconductor “chip” components. The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity.
