Toner cartridges
WARNING: Do not touch the cartridge roller located under the cover.
Your printer uses four separate toner cartridges, one for each color: cyan, yellow, magenta, and black.
They are located behind the front door. The stacking order from top to bottom is black, yellow,
magenta, and cyan.
The approximate yield of the black toner cartridge is 12,000 pages. The cyan, yellow, and magenta
toner cartridges have an approximate yield of 7,200 pages.
The average yield is determined using A4 or letter size paper with a 5% toner coverage. The actual
yield depends on the toner coverage on each page.
When the printer detects the toner supply in a particular cartridge is getting low, it displays
88 <color> Toner Low. If you do not already have a replacement toner cartridge available, order
one at this time. For more information on ordering toner cartridges, 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. Open the Supplies Menu to see which toner cartridge
is low.
The printer continues to display the
<color> Toner Low in the Supplies Menu until you replace the
toner cartridge or until it is empty.
When the life of the toner cartridge has expired, the printer display alternates between the
88 <color> Toner Empty and Open Door Replace <color> messages. You must replace the
toner cartridge to continue printing.
If you notice a reduction in print quality before the 88 <color> Toner Low
message appears, you
may want to replace the cartridge before the message appears. See Identifying other problems for
information about printing problems that may indicate it is time to replace the toner cartridge.
