■ Points to note at servicing
Do not install a used Laser Scanner Unit 2 (C/Bk laser) to the position where a Laser Scanner
Unit 1 (Y/M laser) should be installed.
With this machine, yellow laser is used as a reference to control other colors. This means
that the reference will be changed if the Laser Scanner Unit for YM side and that for CBk side
are replaced with each other. As a result of this, color displacement will occur and may not
be solved. Even if the units are returned after they were replaced with each other once, the
reference was changed when they were replaced, therefore color displacement will not be
solved.
