Maintenance kit Drum cleaner Transfer roller Paper discharger The maintenance kit consist of three components; the transfer roller, paper discharger and drum cleaner. These components work together to transfer your print image to the media you have selected. The paper discharger reduces the occurrence of paper jams at the transfer drum. The transfer roller pulls the image from the transfer drum onto the print media. The drum cleaner removes excess toner and other contaminants from the transfer drum after the print image is transferred to the print media. All three components have an effect on print quality. The approximate yield of the maintenance kit is 120,000 pages. Your printer monitors the life of your maintenance kit. When the maintenance kit reaches the end of its life, the printer shows 80 Scheduled Maintenance. It is time for you to replace your maintenance kit. If you do not already have a replacement maintenance kit available, order one at this time. For more information on ordering a maintenance kit, see Ordering supplies. Press Go to clear the message. The Supplies message appears on the second line of the operator panel to remind you that supplies need attention. The printer continues to show Scheduled Maintenance in the Supplies Menu until you replace the maintenance kit. When the maintenance kit is exhausted, you may experience poor print quality.
