Original Transport from ADF

Transport Method

Non-contact Transport

Contact Transport

Descriptions

Because of the film attached to the glass, the original does not contact the glass.

While passing, the original contacts the glass.

Merit

Sticky material does not normally transfer from the surface of the originals to the surface of the glass.

Stripes in images caused by dust on the glass are rare, because the glass is cleaned by contact with the original as it passes over the glass.

Demerit

Compared with the contact method, dust is more likely to remain in the original feed path, and this causes stripes in the image.

More often than in the non-contact method, stripes in the image occur due to foreign substances that stick to the surface of an original and transfer to the exposure glass.

Aim

To improve prevention of stripes on images caused by sticky foreign substances on the surfaces of originals that transfer to the exposure glass.

Comparing to users of machines for office use, users of this machine tend not to use originals that have sticky substances on the surface. For the main users of this machine, it’s more important to improve prevention of stripes on images caused by dust in the original feed path.

Note

1. Be sure to replace the sheet-through glass with the film attached to the glass.
2. When you attach the film to the glass, you need to keep the left scale attached to the glass in order to ensure the correct location of the film.

3. You can change the method (contact method to non-contact, or vice versa) by replacing the parts.
