2.3 Banding Reduction System (BRS)/ Paper Feed Profile Correction (PFP)
Overview
To ensure high-speed printing and high print quality, this printer is provided with the Banding Reduction System (BRS) and Paper Feed Profile Correction (PFP) function, which are
outlined below:
How to prepare correction data
For each of BRS and PFP, print the relevant pattern for correction data preparation and read the printed pattern through the scanner. Then calculate the correction data and store the data
in the serial flash ROM on the Main Board. The correction data are applied to printing in the supported printing mode.

Conventional models perform overlapping printing (two-pass or four-
pass printing) to reduce banding for ensuring high print quality.
However, the printer provided with the Banding Reduction System
corrects the dot generation rate (amount of settled ink) for each raster,
and performs one-pass printing. This function ensures both high print
quality (reduction of banding) and high-speed printing.

PFP
The conventional paper feed adjustment method is such that the
correction value calculated from the data based on a specific part of the
sheet is reflected to almost all over the sheet. Therefore, the
conventional method cannot cope with the fluctuating error in the paper
feed rate during paper feeding. However, the Paper Feed Profile
Correction function measures the error in the paper feed rate at each of
minutely distributed measuring points on the sheet and provides a
correction value for each point. Thus with this function, the printer
realizes high print quality and high-speed printing on a supported paper
type and in a supported printing resolution.
