Page 5: Note For Servicing
If toner, developer, or ink enters your eyes, wash it away with water immediately, and consult a doctor if necessary. • The machine has got sharp edges inside. Be careful not to dam- age fingers when servicing. • Do not throw toner or a toner cartridge in a fire. Otherwise, toner may ignite and burn you.
Page 6 If the machine is dropped or tips over, it may cause injury or machine malfunction. Use an optional desk or an exclusive-use desk. When using the optional desk, be sure to fix the adjuster and lock the casters. MX-M264U NOTE FOR SERVICING - ii...
