Xerox Printer System considerations, Line density limits, Local density and page setup errors

A.System considerations

Consider the following items when designing and planning your form:

·Line density limits

·Local density limits

·Superimposed edges when adjoining boxes

·Text size in boxes

·Lines with sections.

These items are especially important when designing complex forms. You can avoid error messages and save the time it takes to correct the problems by being aware of the system considerations described in this appendix.

Line density limits

There is a limit to the number of characters and lines you can image on a page. The basic limit is measured in units called dispatchable items.

A dispatchable item has a maximum of 32 dots and can be the following:

·Full characterÐof point size 8, 9 or less

·Fraction of a characterÐgreater than point size 8 or 9

·Line segmentÐequal to or smaller than 32 dots in the scan direction.

Local density and page setup errors

You may encounter a page setup error while the printer is imaging a page. This error indicates there was not enough time for the printer to image a page. One of the following conditions may have caused the problem:

·Excessive amount of data to be imaged

·Disk errors

·Imaging problems

·Local density problem.

If you design a form to avoid exceeding line density limitations, you may cause page setup errors because of local density. Long lines of small text set with close spacing cause a local density problem. The imaging hardware accepts and dispatches characters at two different rates. If the form structure imposes too heavy a dispatchable load, the hardware may run out of input before all of the data has been processed. You rarely encounter this problem in readable forms.
