| print about 1,250 pages/A4 size of standard business |
|
| communications at a typical print coverage of 4% |
|
| (equivalent of CCITT No. 1 test chart). The first toner |

|
| if the print density is high enough, you can continue |
|
| to use the toner cartridge without replacing it until the |
|
| print density becomes too low. |
If the print density becomes low even before your fax machine displays REPLACE TONER CART., gently wipe the lens surface of the LED array (see Step 7). If the print density does not improve, replace the toner cartridge. When your fax machine’s display shows CHANGE DRUM, replace the image drum unit.
Warning: Be careful when handling the toner car- tridge. Do not let toner spill on your clothing or other porous materials. See the Safety chapter at the beginning of this handbook.
