Cleaning the Precharger Wire

T he precharger wire is on the print unit. Normally you should not need to clean this wire. However, the following conditions may indicate that the wire needs cleaning:

•Your printed pages have dark vertical lines, or the print density is uneven.

•Cleaning the corona wire does not solve the problem.

Use the cleaning brush supplied with the printer. This L-shaped tool has two cleaning pads: one for the precharger wire and the other for the corona wire inside the printer. Use the pad on the longer branch engraved “I?“. To clean the precharger wire, follow these steps:

1. Open the upper door of the printer.

2. Remove the print unit from the printer. Place the unit on a level, steady place.

3. Clean the wire. To clean the wire, position the tool as shown in the figure, then gently slide it left and right two or three times along the length of the wire to remove any toner or other particles. Be careful not to break or otherwise damage the wire.

Notice:

•Avoid exposing the drum to light for more than three minutes.

•Do not touch or scratch the drum surface.
