Plot has black vertical lines
Figure 8-6. Plot with black vertical lines
Cause: One or more bits in each byte going to the plotter is “stuck high” possibly due to a faulty
cable.
Solution: Run a test plot. If the lines are not present, the problem originates with the host data.
If the lines are still present, the interface cable is faulty and must be replaced. See Chapter 3 for
interface setup instructions.
Plot is wrong length
If you suspect that a plot is the wrong length, plot a job of a known length and measure it.
Possible causes:
Paper is not moving freely.
Scaling is incorrectly applied.
Vertical emulation is incorrectly applied.
Solutions:
1. Check the paper feed path. Ensure that the paper is installed correctly and that the paper
feed path is not obstructed.
2. Adjust or reset the scaling setting as described in Chapter 4, Operation.
3. Determine if your data requires a specific vertical emulation and adjust the vertical resolution
setting appropriately. See “Vertical resolution” in Chapter 4, Operation.
