# DOCUMENT GLASS

## Overview

This section describes the steps to set the original on the document glass.
When scanning a thick book or other thick original, push up the back of the automatic document feeder and then place the original.
When closing, open the automatic document feeder all the way and then close it.

- Close the automatic document feeder slowly. Abruptly closing the automatic document feeder may damage it.
- Exercise care that your fingers are not pinched when closing the automatic document feeder.

### Maximum original size allowed

Standard sizes |
297 mm (longitudinal) × 420 mm (transversal) 11" (longitudinal) × 17" (transversal)
Non-standard size |
297 mm (longitudinal) × 432 mm (transversal) 11-5/8" (longitudinal) × 17" (transversal)

When the original is a non-standard size, see the appropriate explanation below for the mode you are using.

- Copy: "DIRECTLY ENTERING THE CUSTOM SIZE"
- IMAGE SEND: "SPECIFYING THE ORIGINAL SCAN SIZE USING NUMERIC VALUES"

## Operation

1. #### Open the automatic document feeder

2. #### Place the original

   Place the original with the scan side facing down.
   Align the top left corner of the original with back left (at the tip of the mark ) of the document glass.

   When placing a non-standard size original on the document glass, the size can be detected easily by placing a blank sheet of A4 (8-1/2" × 11"), B5 (5-1/2" × 8-1/2"), or other standard size paper on top of the original.
   Do not place any objects under the original size detector.
   Closing the automatic document feeder with an object underneath may damage the original size detector or disable correct detection of the original size.

3. #### Close the automatic document feeder

   If the automatic document feeder is left open while copying, parts outside of the original will be copied in black, causing excessive use of toner.
