1. Print Density Dial | Has a range of |
| Selecting the lower numbers results in heavier or |
| darker print density. For most printing applications |
| the dial can be set to 7. See Section 2.10 for additional |
| information about setting the print density. |
2. Cleaning Brush | The (green) cleaning brush has two cleaning surfaces: |
| The brush end, which is used to clean the discharging |
| pins on the transfer corona assembly; and the fabric |
| end, which is used to clean the primary corona wire |
| in the |
| information about using the cleaning brush. |
3. Fixing Assembly | The fixing assembly consists of a heat roller, a |
| pressure roller, and a roller cleaner. Toner is bonded |
| to the paper as it passes between the heat and |
| pressure rollers. The roller cleaner removes excess |
| toner that may accumulate on the heat roller. The |
| roller cleaner is replaced each time a new |
| cartridge is installed. Each |

| Section 7.3 for more information about replacing the |
| roller cleaner. |

| blade, toner, and a toner application roller. When |
| the 16 TONER LOW message first appears, it could |
| mean that the toner is not being distributed evenly. |
| Rock the cartridge to redistribute the toner (see |
| Section 7.3). If the 16 TONER LOW message |
| continues to be displayed after you rock the cartridge, |
| it means the |
| you should replace it. Each |
| with replacement instructions, or see Section 7.3 for |
| instructions if necessary. |
5. Ozone Filter | Removes ozone generated by the printer. The ozone |
| filter is replaced every 100,000 pages. The page count |
| is shown on Test Print A (see Section 2.12). See |
| Section 7.4 for replacement instructions. |
| WARNING: Do not operate the printer without the |
| ozone filter in place. The filter removes ozone that |
| could be hazardous to your health. |
