roller occurred, ultimately causing the symptom.

14.3.1.5.6 The poor picture by the attachment mistake of seal support plate (front, rear)
0014-9615
imagePRESS C1 P / imagePRESS C1 / imagePRESS C1+ (Printer) / imagePRESS C1+
Symptom
In the case of mistakenly attaching the seal support plate (front, rear) and printing solid color image in large quantity at one time, the soil of the waste toner may
occur at the both edges of image.
This symptom occurs only when using the A3 size paper or bigger.
Cause
In the case of mistakenly attaching the seal support plate (front, rear) and printing solid color image in large quantity at one time, there may be a space occurring
between the seal support plate and the scoop-up sheet. As a result, there is a case that the soil of the waste toner occurs on the print image due to the drop of waste
toner on the ITB.
