Résumé

The printers emit the chemical compound when its temperature rises during normal operations. And it primarily influenced the chemical concentrations such as formaldehyde and VOCs (volatile organic compounds) in a living space. The measurements on the various types of printers from different manufacturers such as laser jet and inkjet types were performed in emission test chambers of 1 and 5 m3 with a ventilation rate of 1.0 ACH (air change rate) supplying low-polluting clean air. During the test, chemicals emitted per PCs or printers were analyzed on the two modes of stand-by and operation at 25°C and 50% RH. It is found that PCs and printers are a significant source of chemical emissions in small indoor environments, even with adequate ventilation. The chemicals may affect a potential health hazard for computer users.
