8.1.8. IMAGE READING
The Image Reading Part feeds and ejects the document when copying or scanning.
The image reading part consists of the followings.
8.1.8.1. Copying with the Automatic Document Feeder
The automatic document feeder consists of separation roller, document feed roller, separation pad, springs, etc. It divides the
documents and transfers to the reading part, then stacks the documents on the document guide when finished reading.
This automatic document feeder is affordable until 15 documents at once. When the user set a document on the document feeder
and the top of the document is touched, the document detection sensor is turned ON and beep tone sounds, then the motor is
driven.
The driven motor feeds the document and transfers it a little. When the printing part is ready for reading the document, the motor
is driven again by the operation of the user to move the roller at a fixed speed. The documents are fed one by one separated by
the separation pad. The spring plate adds the pressure to the document so that the separation pad can separate the documents
properly. Spring plate helps the document endure the pressure of separation pad to be fed smoothly. The document is ejected
document stacker.
8.1.8.2. Copying with the Scanner Glass
The motor, gear, belt, etc., cause CIS and the carriage above CIS to drive while copying with the scanner glass.The document
should be set to the lower right standard point. Copy can be done without closing the document cover when the
document is thick.When ADF document detection sensor detects the scanner glass, CIS moves to the right of the document from
the home position.
When the printing part is ready for reading the document, the motor is driven again by the operation of the user to move the roller
at a fixed speed. This operation is repeated from the next copy.
8.1.8.3. CIS (Contact Image Scanner)
CIS consists of LED, lens and sensor array. When the light emitted from LED is reflected on the document, the light reaches the
sensor through the lens, then the sensor array detects the document.
