If an error has been displayed on the adjustment program,
confirm the following points and perform the adjustment again.
If an error occurs even after confirmation of the following points,
the error is attributable to any problem with the scanner.
Therefore, perform the adjustment again using another scanner.
1. Make sure that the printer for which the correction value is
registered is the same one that was used to print the
adjustment pattern.
2. Make sure that the printed pattern is located on the document
table properly along the scale.
3. Make sure that there is no clearance between the reference
scale and the printed pattern.
4. Make sure that the scanner glass surface and the reference
scale are free from dust and dirt.
