RM (right margin) 0mm/3mm
Note *: TM and BM are fixed to 20 mm in front manual feeding.
The printer detects the paper width when paper is set. (If the paper width detection
setting is OFF, the printer does not detect the paper width.)
The printer does not print the image exceeding the detected paper width and the
printable area that is specified in the paper setting. (If the paper width detection setting is OFF, the printer may print on the platen.)
The top/bottom/left/right margins (TM, BM, LM, RM) can be set to zero under
special conditions.
Because the printer detects tilt of loaded paper in a range of 3 mm at both left and right sides, an image bleeds off both left and right edges of paper by 3 mm each at borderless printing. However, if the distance between the paper edges and the platen (sponge width) is less than 3 mm, the bleeding margins are adjusted to less than 3 mm (within the range of 0 mm (Refer to "1.4.2 Borderless Printing" (p17), for the borderless print specification.)

RELEASE MECHANISM
Release mechanism consists of a release unit (including a release motor, release sensor, and combination gear), paper guide upper assy that presses papers, and paper guide release shaft that activates the paper guide upper assy. Rotational drive of the release motor activates the paper guide release shaft through the combination gear. When the release lever of the paper guide release shaft presses down the back end of the paper guide upper assy, the paper guide upper assy separates from the PF roller. When the release motor rotates reversely, the paper guide upper assy makes contact with the PF roller. The release sensor installed in the release unit and the light-shielding plate detects the contact condition between the paper guide upper assy and the PF roller.

2.7 Ink Mark Sensor
This printer is equipped with the ink mark sensor functioning as multi sensors. The sensor, located on the bottom of the carriage unit, is a diffuse reflective photointerruptor that is comprised of a light emitting part (white LED) and a light receiving part (photoreceiver). The white LED emits light against the paper or dedicated print pattern printed on paper and the photoreceiver reads the reflected light. According to the reflected light read by the receiver, the printer calculates correction values to perform proper corrective actions. The Ink mark sensor is used for the following adjustments.
Auto Bi-D Adjustment
The sensor scans predetermined patterns printed for the adjustment and detects the highest density pattern among them. According to the detected result, the printer calculates Bi-D correction values automatically.
Auto Uni-D Adjustment
The sensor scans predetermined patterns printed for the adjustment and detects the highest density pattern among them. According to the detected result, the printer calculates Uni-D correction values automatically.
Auto Nozzle Check
The sensor scans a nozzle check pattern. The pattern is printed with the all nozzles and each nozzle prints one block. If there is a clogged nozzle, the corresponding block will not be printed and detected by the sensor, and a head cleaning is performed automatically.

Opening/closing of the cover is controlled by the lock mechanism that takes advantage of an electromagnetic solenoid, and the cover can only be opened by means of the operation panel. When the operation to open the cover is performed, the solenoid is energized and the lock is released. The solenoid unit is equipped with a switch sensor that detects opening/closing state of the cover.

Colorimetric Calibration (Color ID) Overview
This printer employs “Colorimetric Calibration (Color ID)” to correct unit-to-unit variations in color. Colorimetric Calibration (Color ID) corrects not only the weight of ink droplets which differs depending on the individual characteristics of print head but also variable factors such as drive circuit and voltage. This enables a higher-accuracy calibration.
OVERVIEW
1. Printing/ Measuring the color of a correction pattern A correction pattern printed by a completed product is used for the calibration. A calibrator is used to perform the color measurement of the printed pattern.
2. Writing the correction value Correction values are automatically calculated based on the result of the color measurement and stored in the NVRAM on the main board.
3. Reflecting the correction value Every time the printer makes a print, the printer driver reads out the correction values from the NVRAM. Each ink droplet weight and the number of ink droplets for each dot are corrected according to the information.

This printer is equipped with a lithium battery. When handling
the lithium battery, the following precautions should be followed.
x When replacing the battery, replace it with a specified type
of battery. Using a different type of battery may cause excess heat or explosion.
x Dispose of used batteries according to manufacture’s
instructions and local regulations. Contact your local government agency for information about battery disposal and recycling.
x When disposing of the battery, be sure to securely cover the
positive terminal (+) of the battery with a tape to prevent combustion or explosion.
x Do not charge the battery. x Do not use the battery if it is discolored or damaged, or if any
leakage of electrolyte is observed.
x Do not dismantle, solder or heat the battery. Doing so could
result in leakage of electrolyte, heat generation, or explosion.
x Do not heat the battery or dispose of it in fire. x If the electrolyte leaked from the battery contacts with your
skin or gets into your eyes, rinse it off with clean water and see a doctor immediately.
As the power switch is installed on the secondary side of the
power circuit, power is always supplied unless the power cord is unplugged. Unless otherwise stated, be sure to unplug the power code before disassembling or assembling the printer to prevent electric shock and damage to the circuit.
Always wear gloves for disassembly and reassembly to avoid

C A U T I O N
Ensure sufficient work space for servicing. Locate the printer on a stable and flat surface. The ink-path-related components or parts should be firmly and
securely installed on the printer to prevent ink from leakage.
Use only recommended tools for disassembly, assembly or adjustment of the printer.
When using compressed air products; such as air duster, for
cleaning during repair and maintenance, the use of such products containing flammable gas is prohibited.
Apply lubricants and adhesives as specified. Be careful not to soil the printer or the floor with the leaked ink
when removing the ink-path-related components or parts. Spread a sheet of paper or cloth on the floor in advance.
Do not touch electrical circuit boards with bare hands as the
elements on the board are so sensitive that they can be easily damaged by static electricity. If you have to handle the boards with bare hands, use static electricity discharge equipment such as anti-static wrist straps.
When reassembling the printer, make sure to connect the
connectors of the electric components or parts correctly and securely. Use extreme care when connecting FFCs (flexible flat cables). Improper connection of the FFCs, such as inserting them diagonally into the connectors, could cause short­circuiting and lead to breakdown of the electric elements on the boards.
When reassembling the printer, make sure to route the FFCs
and other cables as specified in this chapter. (Failure to do so may cause an unexpected contact of the cables with sharp metal edges, or lead to lower the noise immunity.)
When the printer has to be operated with the covers removed,
take extra care not to get your fingers or clothes caught in moving parts.
When you have to remove any parts or components that are
provided as after-service-parts but are not described in this chapter, carefully observe how they are installed and make sure to remember it before removing them.
When you removed any parts or components that are secured
with black acetate tape or two-sided tape, be sure to reinstall and secure them with the tape as exactly the same as they were.
C A U T I O N
Disassembling the frame and some components of the printer is
prohibited because they are assembled with precise measurements in 1/100 mm unit at the factory.
