Print cartridges Warning! Do not touch the cartridge by the photoconductor or shutter assembly. Handle Photoconductor and shutter The photoconductor is the green cylindrical drum in the print cartridge under the shutter. Together, the photoconductor and the toner create the print cartridge. The approximate yield of each print cartridge is 10,000 pages. This average yield is determined using A4 or letter size paper with a 5% toner coverage. The actual yield depends on the density of print on each page. The maximum yield of each print cartridge is 15,000 pages. At this point, the cartridge must be replaced. When the printer detects the toner supply in a particular cartridge is getting low, it displays 88 Color Low. If you do not already have a replacement print cartridge available, order one at this time. For more information on ordering print cartridges or the print cartridge, see "Ordering supplies" on page 113. Press Go to clear the attendance message. The Supplies status message appears on the second line of the operator panel to remind you there are supplies that need attention. Open the Supplies Menu to see which print cartridge is low. The printer also continues to display the 88 Color Low message each time you turn the printer on and each time you open and close the fuser cover, until you replace the print cartridge or until it's empty. Whether or not the printer stops printing when a toner low condition occurs is based on the Toner Alarm setting under the Setup Menu. If Toner Alarm is set to single or continuous, the printer will stop printing. If Toner Alarm is set to Off, the printer will display the 88 Color Low and continue to print. When the life of the print cartridge has expired, the printer displays Color Cartridge Empty. You must replace the print cartridge. If you notice a reduction in print quality before the 88 Color Low message appears, you may want to replace the cartridge before the 88 Color Low message is displayed.
