HP Designjet 9000s Printer Series - What Affects Volatile Organic Compound Concentration in the Work Area

Information
Total Volatile Organic Compound (VOC) release from HP Designjet 9000s printers is directly related to the amount of HP low-solvent ink used. Higher production levels mean more VOCs will be released. Adding an optional HP High Speed Dryer significantly increases the release of VOCs from prints into the work area.
A number of other factors act to increase or decrease the concentrations of VOCs in the general work area. Some of these factors are summarized below.
Work area VOC concentrations increase with:
  • High print production during short periods of time
  • Producing prints with high print density (more ink used)
  • Smaller work area room volume
  • Installing more HP Designjet 9000s printers in the work area
  • Poor airflow through the work area
  • Using an optional HP High Speed Dryer
  • Reduction in fresh air supply
  • Placing HP Designjet 9000s printers and HP High Speed Dryers away from room exhaust vents and upstream of work areas
Work area VOC concentrations decrease with:
  • Larger work area room volume
  • Increase in fresh air supply
  • Air circulation fans in the work area that are designed to reduce air stagnation
  • Using air extraction or an HP Air Purifier System with each HP Designjet 9000s
  • Placing HP Designjet 9000s printers and HP High Speed Dryers close to room exhaust vents and downstream of work areas
Because of all these variables, designing an adequate ventilation system is complex and depends on your particular installation. Consult with an industrial ventilation engineer and a certified industrial hygienist to determine ventilation requirements for your print production facility. You should consult an environmental engineer to determine if permits or air pollution controls are required in the location where you do business. A certified industrial hygienist will be able to advise you on any mandatory work practices or exposure limits for workplace safety that apply to your facility.
