HP LaserJet and HP Color LaserJet Series Printers - Information about Ozone Emissions

Overview

As laser printing has become more popular, HP Color LaserJet and LaserJet series printer emissions have raised concern. Much of the information (or lack of information) has caused undue alarm about the use of these products. Emissions from these printers are below the standard levels established by various regulatory agencies and standard-setting organizations. The following information addresses the issues surrounding ozone and provides a better understanding of what ozone is, its effects, how it is measured and what can be done to control it. NOTE: The HP LaserJet IIP, IIP Plus, and IIIP series printers generate ozone emissions far below 0.1 parts per million while printing. The HP LaserJet IIISi, 4, and 4M series printers do not emit ozone at any time. The reason is that none of these printers have corona wires.

Sources of ozone

Ozone is a pure oxygen molecule containing three atoms of oxygen instead of two. Ozone is present in the air, but the highest concentration is found in the earth's upper atmosphere. Ultraviolet radiation creates the primary source of ozone. Other sources of ozone are created by electrical discharges and are what people detect when they say they "smell electricity." Some people sense this smell near electric motors, high voltage lines, or after lightning storms. The ozone generated by some laser printers and photocopiers is a by-product of the electro-photographic process and is generated when the corona assemblies place charges onto photo-conductive materials. In the case of HP Color LaserJet and LaserJet series printers, this ozone is generated only while printing (while the coronas are energized). No ozone is generated when the HP LaserJet series printer is in standby mode.

Effects of ozone

The ability to detect the odor of ozone varies greatly among people. Likewise, the sensitivity of people to ozone is different. Ozone can cause eye, nose, throat, and lung irritation. It can also cause headaches and dryness of the eyes, nose, and throat. The smell of ozone in low concentrations is often described as sweet. In higher concentrations, however, it is more pungent. Most people are not affected by ozone emissions from a laser printer. The ozone generated by laser printers has a very short life span and decomposes back to oxygen very rapidly. In the average office, ozone concentrations usually will not last longer than a few minutes.
Air emissions and regulations
HP characterizes the ozone emissions from all printer platforms to commercial release of the products. These systems are tested by printing on multipurpose paper in controlled environmental chambers, and the ozone emission rates are directly determined. These rates are subsequently used to calculate the concentration of ozone expected in an office environment with low air ventilation, but with a high printing rate. These ozone concentrations are then compared to worldwide occupational exposure limits, as well as more stringent indoor air quality guidelines. Specifically, the US OSHA Permissible Exposure Limit of 0.2 milligrams per cubic meter, and the GREENGUARD ecolabel criteria of 0.02 mg/m3 are referenced. In considering ozone concentrations in the "default" office scenario mentioned above, the few older printer models (and the HP Color LaserJet 8500 series printer) with required filters are well below the PEL, and the newer printer models generally yield non-detectable results.

*US OSHA PEL is the regulatory limit for occupational exposures - significant worldwide limits are generally very similar to this value. **GREENGUARD criteria for the US ecolabel program is the maximum concentration allowed for a "low-emitting" printer. ***Reported values are based on the concentration of ozone determined by the following factors: A 32 cubic meter room With 0.8 air changes per hour Printing on multipurpose paper for two hours, over an eight hour day
Customer/employer responsibility
The customer needs to ensure that a printer is installed in a work environment that will ensure its safe operation. In general, the system should be located in an open area that provides good ambient air movement and an adequate distance from the user (not situated directly adjacent to the exhaust vent). In an occupational environment, the employer is responsible for ensuring that actual ozone concentrations are below limits specified in the recognized workplace safety regulations. The employer may want to analyze the ambient air in the immediate area.
Conditions for printer set-up and operation
For use associated with the printer operation, see the User Manual that comes with the printer. Also, the following steps are suggested to minimize any remote issues with ozone: Ensure proper ventilation for the printer Ensure proper office conditions with regard to humidity Observe the proper site locations for the printer to ensure proper air movement and ventilation within the work area Ensure the direction of the printer exhaust is not in close proximity or pointed towards an individual Where a filter is utilized, ensure replacement at suggested intervals

Changing ozone filters

NOTE: The products NOT in the following table use a different technology that does not generate measurable amounts of ozone, therefore an ozone filter is not necessary. All the HP LaserJet series printers listed below use an ozone filter. For the products that are listed, the following information on ozone filters is applicable. HP recommends that the ozone filters be replaced every three to four years or 50,000 pages, whichever occurs first, to ensure that the printer is operating at HP LaserJet & HP Color LaserJet Series Printers - Information about Ozone Emissions
its safest level. The filters do not wear out; however, they can become clogged with dust, which greatly reduces their effectiveness. The chart below defines which HP LaserJet printer models have filters that can be user-installed and those that need to be installed by authorized HP LaserJet series printer service personnel.

HP recommends that authorized HP Color LaserJet and LaserJet series printer service personnel install this kit. NOTE: There are no special disposal requirements for ozone filters. Because ozone decomposes back to oxygen rapidly, no hazards are associated with used ozone filters. The filter is simply a carbon screen that acts as a catalyst. The filter itself contains no ozone.

Conclusion

HPs goal is to continually improve its products to make a positive contribution to the environment. HP also aims to inform its customers of all pertinent information concerning the use and safety of its products. However, the customer is ultimately responsible for making sure the work place is safe and comfortable. If an abnormal operating condition exists, such as those described above, it is the customers responsibility to correct the situation.

indicate in which part of the paper path the paper is jammed. Also, the paper jam sensor at the rear of the fusing assembly may have become stuck. Check the optional duplexing paper path if the duplexer has been installed. Paper jams can occur in these printers when using the "automatic manual feed" as opposed to explicitly putting the printer in manual feed mode. The use of "automatic manual feed" is not a supported feature, nor is it a suggested procedure. This procedure is known to cause problems, particularly when using the lower cassette as the manual feed slot because it is more difficult to align the paper properly when it is pulled in from the lower input slot. Paper is the only print media that should be fed from the lower input slot and other types of media may not only cause jamming, but also permanent printer damage. Paper is jammed in the paper path or the paper jam sensor at the rear of the fusing assembly may be stuck, causing a false paper jam warning. Remove jammed paper. While clearing paper jams the top cover or rear cover must be opened and closed again before pressing Continue or online to resume. Check that the rear cover is closed; an open rear cover may cause a paper jam. If no paper jam is found, check locations shown in the user's manual. Paper is jammed in the top or rear of the printer. Clear jam and press Continue or Online to resume printing. To prevent further jams, verify the rear door is closed securely. A false paper jam message will occur if the printer's back door is open. If message persists, the printer could have a defective paper jam sensor and service would be required. There is no toner cartridge in the printer, or this message indicates the possibility of a broken or damaged toner cartridge. Turn the printer off and back on. If the message returns replace toner cartridge. After replacing cartridge if the message still occurs consult service. Engine Test with a single sheet of vertical line printout also known as a

HP LaserJet, Plus, 500 Plus printers
The printer's Interface board has detected an internal error. Check for an improperly seated font cartridge or data cable. Turn printer off and back on. If the message persists, consult service. An expansion memory card (SIMM) has been installed incorrectly (out of sequence) into the slot indicated by the error code. The printer will still be able to print, but will only be able to use the memory below the faulty card. Four megabyte cards go in first from bottom slot up, then one megabyte cards. Turn the printer off and reorganize the memory cards into their correct slots. See page G-7 of the User's Manual. A SIMM that is the wrong size or speed is installed. The HP LaserJet IIISI printer support 1, 4, and 8 MB, 36 -bit SIMMs rated at 80 NS. Check that installed memory meets these specifications. Press Continue to temporarily clear this error. The printer will still print, but will only be able to use the memory installed below the SIMM in question. See pages G-2 and G-14 of the User's Manual The printer encountered a parity error when accessing the RAM memory SIMM in slot "X". If X=0, the slot with the defective SIMM could not be determined. Switch the printer off and then back on. (Data stored in printer will be lost.) If the error present, first switch the printer off and verify that the SIMM board is installed correctly. Switch the printer on. If the error is still present, switch the printer off and remove the SIMM board If the error message does not appear, the problem is on the SIMM. If the message still appears, the problem is in the printer's internal memory and requires service. The printer identified a problem

I/O buffering and/or Resource Saving settings were altered when the printer was switched on because the printer did not have enough memory. This usually occurs after memory has been removed from the printer. (Check settings by printing a self-test.) There is still sufficient memory to accommodate resource saving, but the current setting cannot be satisfied by the available memory. Reconfigure the resource saving for the current personality. The Resource saving memory area for the specified personality is full. Press SHIFT and Continue to continue printing (some data will be lost). The current job will print, but some resources (downloaded fonts, etc.) may not be saved. If this error occurs frequently, you may need to adjust Resource Saving settings.
