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.

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.

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.
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.

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.
