Carriage cannot park | Mispositioned trailing cable: The trailing cable may be |
in service station. | preventing the carriage from reaching the left9hand stop. Make |
| sure that the trailing cable is positioned under the plastic tabs at |
| the back of the carriage cover, and not above them. |

|
Drive belts wear out | Diazo copiers: The belt may wear prematurely if the plotter is |
prematurely. | placed near a diazo copier that uses ammonia to produce blue9line |
| copies. The material used in the belt is very reactive to ammonia |
| vapor. The vapor is very corrosive and can damage other parts as |
| well. Move the plotters away from such copiers. |
| Storing: Keep new belts in their bags with dissicant until you need |
| to install them. This is to avoid incorrect swelling. |

|
Noisy carriage | Dirty carriage wheel: Remove aluminum or dust particles from |
movement. | the wheel at the back of the carriage, and from the slider path along |
| which the wheel moves. |

|
Bail mechanism fails. | Wearing of parts: The cam gear and engaging gear may not make |
| correct contact with the left drive9roller gear even though the |
| carriage is actuating the engaging lever. This can happen due to |
| excessive wearing of parts. Another problem may be that the bail |
| cable has broken. |
| Carriage motor control: The carriage may not properly locate |
| the engagement lever, preventing the gears from engaging. Any |
| problems with the carriage9motor control system (for example, the |
| encoder strip) or associated mechanics could cause this problem. |
| Also, if the carriage cannot find the true left stop during |
| initialization (caused by interference), the engaging lever cannot be |
| located. |
| Bail cam: The bail may fall from the up position. This can happen |
| if the cam is over or under9rotated. The notch on the cam, used to |
| engage the left bail bracket, is not properly located for the •bail up" |
| condition, and the bail falls abruptly. Perform a bail cycle test. |
| Adjust carriage: If the carriage moves over the engaging lever |
| without raising it, you may need to adjust the carriage angle on the |
| slider rod. (Details ' page 7911.) However, be careful not to |
| jeopardize the print quality, which is very sensitive to the carriage |
| angle. |

Bail starwheels slip | C!clips: Ensure that the c9clips and bushings are correctly installed |
off overdrive roller | on the left end of the overdrive roller, to prevent its movement from |
wheels. Media jam. | side to side. |
|
|
Ink spilling. | Spittoon and ink separator: You need to replace these parts |
| when they fill up with ink. (See ' chapter 4.) |
|
|
Static charge causing | Anti!static brush: If this brush (located under the entry platen) is |
media jams. | damaged or removed, static charge can build up on the media. A |
| charge can cause the media to stick to itself and jam the plotter. |
