The accumulation of dust or particles that are shed in the equipment can require more frequent cleaning and can cause abrasion to equipment parts. Over time, dust and stickies may also damage the photoreceptor in reprographic equipment. At postconsumer content levels of 10-25%, contamination from stickies can affect the photoreceptor, potentially leading to premature failure of this component. This problem occurs slowly and incrementally over time. It does not necessarily affect the readability of the machine’s copies and while it may not be detected by a customer; it is always discernible by a technician.
