What is a way to minimize the effect of the error in a gravimetric analysis where the precipitate that is formed is too soluble causing an underestimated effect on the analysis result because not all the ions being analyzed will be in precipitate?

Either choose a more insoluble precipitate, or wait until the precipitate settles and add more reactant to the supernatant solution.

Well, if solubility increases as temperature increases, lower the temperature. Although I doubt this would be practical or cause a significant increase in the accuracy of the results.
