Photoconductor (PC) Life Warning or a Replace Photoconductor message on the printer screen indicates that the photoconductor unit in the printer is near or past its expected life rating of 30,000 single-sided pages. You will need to replace the photoconductor unit inside the printer when you see this message. NOTE: It may occasionally be necessary to replace the photoconductor unit in order to correct a print quality problem such as toner streaks on the page.

WARNING! When replacing a photoconductor kit, do not leave the new photoconductor kit exposed to direct light (especially sunlight) for an extended period of time. Extended light exposure can cause damage to the new photoconductor kit, which may lead to print quality problems.
