The effect of FWL on the coefficients in implementing digital controllers has been the subject of many recent studies. Especially, this issue is more severe in the low budget consumer electronic products. To save the cost of development, most of the manufacturers applied cheap processors on those kinds of products. Therefore, it is desired to develop an estimation to predict the required wordlength while designing the controller. In this paper, we will focus our study on an inkjet printing mechanism and investigate the effect of a controller without a proper wordlength. We will develop an algorithm to estimate the required resolution and apply the method to determine the required bits of wordlength for the controller designed.
