Transfer results

Explanation

• When an abnormal print appears, place around problem part can be defined to some extent by

transferring the image data.

• Transfer the data from “1. Main” to “4. Laser control PCB”, check transferred image data in

each section, and [Abnormal] is displayed at the place where the problem occurs.

Refer to the Service Manual 35900.

• When an abnormal print appears even though all transfer results are [Normal], check around the

laser unit section.

Note

• This mode is effective only when an abnormal print appears in spite of an error having not

occurred.
