Cartridge Carriage Rubbing against Encoder Strip
When properly installed, the encoder strip should pass through the cartridge;carriage assembly without touching it. Sometimes excessive rubbing may be experienced, causing the encoder strip to buckle or vibrate, and thus causing errors in the carriage;axis servo feedback system and poor carriage;axis position tracking.
You can adjust the encoder;strip position by adjusting the position of the encoder spring bracket. To do this, perform the following procedure:
1Remove the power cord from the plotter.
2Remove the window, center cover and right endcover.
3Manually position the carriage assembly in the center of the plotter.
4Loosen the top and bottom screws of the adjustable encoder;spring bracket.
5Manually move the bottom of the bracket about the bracket's top screw until the encoder strip is centered in the carriage; then tighten the screws.
Premature Wearing of Drive Belts
The main belt or the small Y;drive belt may wear prematurely if the plotter is placed near a diazo copier that uses ammonia to produce blue;line copies. The material used in the belts is very reactive to ammonia vapor. The vapor is very corrosive and can damage other parts as well. It is recommended to move the plotters away from such copiers.
Sensor does not Correctly Find Media Edge
Excessive ink deposits on the drive;roller surface can fool the sensor by reflecting the light. (Cleaning roller chapter 4.)
Last Swath is Clipped when Replotting
This bug on DesignJet 200 plotters will be solved in firmware revision A.01.02. (Details chapter 9.)
