03 Safety information
3.1 BIO X system warnings
• Please consult the BIO X manual for BIO X-specific and general warnings and safety procedures.
3.2 EMD Printhead warnings
• Do not clean the printhead by submerging it in liquid or using excessive spraying. Liquid inside the printhead can damage the circuitry and
motor. To clean the EMD valve, you must remove it from the printhead and follow instructions in the
Maintenance section .
• The LED on the printhead will turn yellow to indicate a warm printhead and red to indicate a hot printhead. Do not touch the printhead when
the LED is red. Touching a hot printhead risks serious injury.
• Do not manually move the printhead mount. Moving the printhead mount manually will damage the motor. If the mount needs to be moved,
place the printhead in the loading position described in the Getting Started section.
• Use the proper method to load and unload the EMD Printhead onto the BIO X printhead mounts. Instructions are outlined in the Getting
Started section. While loaded on the BIO X, do not pull or push the printhead with excessive force, especially when the BIO X system is
turned on. Doing so will damage the motor and its guides.
• Do not use a jerking motion to remove the printhead. Using a jerking motion risks hitting and damaging the HEPA filter.
• Handle the threaded nozzle and needle with care or the needle may bend and affect dispensing.
• Handle the microvalve end with care. When inserting and removing the valve, do not touch the outlined area (Figure 2).
• Avoid using tools or excessive force to tighten the nozzle into the printhead.
