Refer to Table 1-20.
When “Fit to Page” is selected by the key operation, a copy is made adjusting the image size to the paper by enlarging/reducing the original. The zoom ratio is determined as follows, and the same ratio is applied to both horizontal and vertical sides.
• Detects the image size of the original using the preview function.
• Calculates an appropriate zoom ratio from the image size and the printable area of the paper.
• If the ratio falls into less than 25%, 25% is applied. 400% is applied if over 400% likewise.
• For color/B&W copying, the zoom ratio is determined so as to make a copy of the whole image of the original on the paper.
• For photo copying, the zoom ratio is determined so as not to leave any margins on the paper.

1.7.4 Multiple Copying
Making 20 (fixed value) copies in color/B&W becomes available by operating specific keys (Refer to p. 22). In this copying, the second copy or later are carried out without scanning by storing the scanned data in the memory to makes copying faster. However, if the scanned data is bigger than the memory’s capacity, scanning will be repeated for each copy. The conditions that the scanned data can be stored in the memory are as follows.

Storing the data/repeating scanning
The scanned data can be stored. The second or later will
*
be printed without scanning. Tries to compress the scanned data to store it in the
memory. Some data can not be stored, scanning will be repeated after the second in that case.

2.1 Overview

In this chapter, the product names are called as follows:
Revision D
This chapter describes the mechanism of NX100 series and NX110 series.
2.1.1 Printer Mechanism
NX100 series and NX110 series printer mechanism consists of printhead, carriage mechanism, paper loading mechanism, paper feed mechanism, and ink system.
As the conventional models, NX100 series and NX110 series are equipped with two DC motors; one is used to drive the paper loading, paper feed mechanisms, and the pump mechanism that includes the carriage lock mechanism, and another one is used to drive the carriage mechanism. A paper is fed from the rear ASF unit by means of the LD roller and Retard roller and ejected to the front tray.

2.2 Power-On Sequence

This section describes the power-on sequences for this product.
Condition
Completing ink charge.No paper on the paper path.The Printhead is capped with the Cap of the Ink System.The Carriage is locked by the CR Lock.
Table 2-3. Operation of the power-on sequence
Operation
1. Checking waste ink overflow
1-1.Reads out the protection counter value to check waste ink overflow.
2. Seeking the home position
2-1.The carriage moves to the 80-digit side slowly and confirms it
touches the CR lock.
2-2.The carriage moves to the 0-digit side slowly to leave from the CR
lock.
2-3.Checks if paper does not exist with the PE sensor and the PF Motor
rotates clockwise to release the CR lock.
2-4.The carriage moves to the 80-digit side slowly and confirms that the
CR lock is released.
2-5.The carriage quickly moves to the 80-digit side by the Left Frame.

Operation
4. Detecting ink cartridge and initializing ink system
4-1.The carriage moves to the 80-digit side for IES detection.
4-2.The carriage returns to its home position.
4-3.The carriage slowly moves to the CR lock set position.
4-4.The PF Motor rotates clockwise.

4-5.The PF Motor rotates counterclockwise and sets the CR lock.
4-6.The carriage slowly returns to its home position.

Note *1 : The rotation direction of the PF Motor is as follows.
Clockwise direction : Paper is fed normally Counterclockwise direction : Paper is fed backward
*2 : The conditions of the CR lock are as follows.
Red: CR lock is set White: CR lock is released
*3 : Executed when the detected temperature is under 5 oC (41oF) by the thermistor on the
Printhead.
*4 : The empty sanction operation may occur depending on the situation.

2-6.After the carriage continuously moves to the 80-digit side slowly
and confirms it touches the Left Frame, sets the distance from the home position to the Left Frame as the theoretical value.
2-7.The carriage quickly moves to the 0-digit side and slows down as it
gets to its home position, and stops there.
3. Low temperature operation sequence
3-1.The carriage moves back and forth between the 0-digit side and the
80-digit side for two times.
