Figure 5-13. BRS Test Pattern
In the Adjustment program, the identification code is used to
distinguish whether the printer that printed the pattern and the
printer to register the adjustment value is the same.
Make sure to let the printed pattern dry for more than 5
minutes if using CIS sensor type scanner. When using CCD
sensor type scanner, the printed pattern does not need to be
dried before scanning. Refer to

5. Set the printed pattern and the PFP Base Scale on the document table and click the
[Scan] button on the "3. Scan Test Pattern" column.

the document table glass and the scale is clean, and the scale/adjustment pattern is
not tilted, then repeat from step 5.
Be careful of the following when setting the PFP Base Scale, and
the adjustment pattern on the scanner.
Place the scale on the document glass aligning the scale corner
with the scanner origin position.
Place the pattern-printed sheet along the scale as shown in the
figure below. Make sure to place it parallel to the scale, with
