1.1.1 Mark Detection
Mark shape
The procedure described below is for 4-point mark detection that is performed after media detection.
At 4-point mark detection, the registration marks will be detected in the following order:
TP1 (Vertical →Horizontal) →TP3 (Vertical →Horizontal) →TP4 (Vertical →Horizontal) →
TP2 (Vertical →Horizontal)
Processing sequence (1/3)
Step Processing Description
1 The plotter enters mark
detection mode
1. If mark detection is set to any other than OFF in the [CUT MODE] -> [SETUP] ->
[MARK DETECT] procedure, the light pointer turns on after media detection and the
system moves to the mark detection mode.
2Move the light spot of the
light pointer into the mark
detection start area
1. By operating JOG keys, move the light spot of the light pointer into the mark detection
start area and then press the [ENTER] key.
3 Photo sensor moves to the
light spot position
1. The mark sensor moves to the light spot position by the cut head carriage and media feed
operation.
4Searching for vertical line
of mark (TP1)
1. The head moves in the Y-axis left direction (for type 1) or Y-axis right
direction (for type 2) until the mark sensor turns on and stops.
2. The head moves in the Y-axis left direction (for type 1) or Y-axis right
direction (for type 2) by the distance of HM.
3. The head moves in the Y-axis right direction (for type 1) or Y-axis left
direction (for type 2) until the mark sensor turns on and stops.
4. The plotter determines the center of the vertical line based on the positions
of “1” and “3”.
5. Finally the head moves in the Y-axis right direction (for type 1) or Y-axis left direction (for
type 2) by the distance of HM and terminates.

5 Searching for horizontal
line of mark (TP1)
1. The head moves in the X-axis upper direction (for type 1) or X-axis lower
direction (for type 2) until the mark sensor turns on and stops.
2. The head moves in the X-axis upper direction (for type 1) or X-axis lower
direction (for type 2) by the distance of HM.
3. The head moves in the X-axis lower direction (for type 1) or X-axis upper
direction (for type 2) until the mark sensor turns on and stops.
4. The plotter determines the center of the horizontal line based on the
positions of “1” and “3”.
5. Finally the head moves in the X-axis upper direction by the distance of HM and terminates.
6Searching for vertical line
of mark (TP3)
1. When the distances between the marks are known by the procedure for scale compensation
with the setting value “BEFORE”, the head moves in the X-axis upper direction by
“Distance between marks -Length which is twice the mark size”.
2. The head moves in the Y-axis left direction until the mark sensor turns on and stops.
3. The head moves in the Y-axis left direction by the distance of HM.
4. The head moves in the Y-axis right direction until the mark sensor turns on and stops.
5. The plotter determines the center of the vertical line based on the positions of “2” and “4”.
6. Finally the head moves in the Y-axis left direction (for type 1) or Y-axis right direction (for
type 2) by the distance of HM and terminates.
• If the vertical line is not detected even after a search of the maximum printing range,
[ERROR36-C MARK DETECT] appears.
7 Searching for horizontal
line of mark (TP3)
1. The head moves in the X-axis upper direction (for type 1) or X-axis lower direction (for
type 2) until the mark sensor turns on and stops.
2. The head moves in the X-axis upper direction (for type 1) or X-axis lower direction (for
type 2) by the distance of HM.
3. The head moves in the X-axis lower direction (for type 1) or X-axis upper direction (for
type 2) until the mark sensor turns on and stops.
4. The plotter determines the center of the vertical line based on the positions of “1” and “3”.
5. Finally the head moves upward by HM of the horizontal line of TP3 and to the left (for type
1) or to the right (for type 2) by HM of the vertical line.
• If the horizontal line cannot be detected, the plotter determines that the vertical line
detected above is not part of a mark and repeats the procedure from Step 6.
8Searching for horizontal
line of mark (TP4)
1. When the distances between the marks are known by the procedure for scale compensation
with the setting value “BEFORE”, the head moves in the X-axis upper direction by
“Distance between marks -Length which is twice the mark size”.
2. The head moves in the X-axis upper direction until the mark sensor turns on and stops.
3. The head moves in the X-axis upper direction by the distance of HM.
4. The head moves in the X-axis lower direction until the mark sensor turns on and stops.
5. The plotter determines the center of the horizontal line based on the positions of “2” and “4”.
6. Finally the head moves in the X-axis upper direction (for type 1) or X-axis lower direction
(for type 2) by the distance of HM and terminates.
• If the horizontal line is not found even after a search of a range up to 5 m, [ERROR36-C
MARK DETECT] appears.
• If “no media” is detected at the tail end detection position during a search for a
horizontal line, the plotter performs the tail end detection of the media first and then
continues horizontal line detection.
9 Searching for vertical line
of mark (TP4)
1. The head moves in the Y-axis right direction (for type 1) or Y-axis left direction (for type 2)
until the mark sensor turns on and stops.
2. The head moves in the Y-axis right direction (for type 1) or Y-axis left direction (for type 2)
by the distance of HM.
3. The head moves in the Y-axis left direction (for type 1) or Y-axis right direction (for type 2)
until the mark sensor turns on and stops.
4. The plotter determines the center of the horizontal line based on the positions of “1” and “3”.
5. Finally the head moves in the Y-axis right direction by the distance of HM and terminates.

6-color ink set
Two paths of the same color are linked shortly after the cartridge valves.
Normally the valve of 1 cartridge per color is opened by toggle switching, supplying ink to a
2-nozzle row.
Thereafter, the cartridge on the side with the open valve is referred to as the control cartridge,
while the other is referred to as the sub cartridge.
Longer consecutive drawing time than conventional products and replacement of cartridges
during the drawing are allowed by toggle switching of 2 cartridges for 1 supply path.
2Except M and Bl ink
when filling6-color ink
set
When filing 8-color,
6-color+W,
or 6-color+W ･Si
1 cartridge is connected to a 1-nozzle row. No toggle is switched and all cartridges are control
cartridges.
Since 1 cartridge is assigned to 1 path, it cannot be replaced during printing.
3 Ink supply system The ink filling method uses a suction system with a roller pump, and a pressure damper with
a self-sealing valve.
Ink is supplied with a siphon during printing.
The damper sealing valve opens to supply ink when the discharge pressure drops, and the
sealing valve closes when the damper ink chamber is filled.
The sealing valve reduces the ink path pressure that reaches the head meniscus during the
carriage motion.
4Replacing ink cartridge The warning message is displayed if the cartridge is not installed even after a lapse of 10
minutes to prevent the supply system from getting dry.
5 Ink supply valve For each cartridge, a supply valve is provided to supply ink by opening it.
The supply valve is normally closed and is opened only when ink supply is required.
Ink supply is executed during discharge operation (for printing or flushing) and suction
operation (for cleaning or filling). The supply valve for any cartridge that has developed an
error does not open, thus does not allow ink supply.
6Ink cartridge LED For each cartridge, LED is used to allow the user to visually check the cartridge state.
Green color lights in control. Red color lights in error.
Since all 8 cartridges are control cartridges except when 4-color ink set is used or except M
and Bl ink when 6-color ink set is used, Green color lights on for cartridges where there is no
error.
7 Ink use-up cleaning
(Only for the 4-color ink
set)
For cleaning, the machine switches the supply valve to the cartridge that has displayed [INK
NEAR END] or [INK END] to use the cartridge with the smaller amount of residual ink first.
For details, see "1.3.7 Use-up Cleaning".

1.3.2 Ink System Error Monitoring
Monitoring of cartridge error
Monitoring of ink system error
The ink system are checked for any error periodically (every 30 ms), and machine operation is limited according to
the error, if detected. The table below shows the possible errors and the limitations on machine operation.
*1 Ink IC: NON-ORIGINAL INK, WRONG INK IC, Kind of INK, Color of INK, WRONG CARTRIDGE,
Expiration:2MONTH
*2 : Executable X: Inexecutable
No. Item Description
1 Cartridge error check A cartridge error is periodically checked (every 30 ms).
 Select the supply cartridge in taking into account the error status and the amount of remaining ink.
2LED control when an
error occurs
The LED (blue) lights up to indicate that the supply cartridge is now being controlled.
The LED (red) lights up or blinks to indicate that the cartridge must or should be replaced.
3 Supply valve control
when an error occurs
 The valve for the cartridge where the LED (blue) is lit opens when the instruction to open the valve is issued.
When an error occurs in a supply cartridge while the valve is open (during printing or
cleaning), the valve switches to the other cartridge which can supply ink, if any, to continue
machine operation. If a supply cartridge is removed, printing or cleaning will be stopped and
the machine will return to LOCAL mode.
Since all 8 cartridges are control cartridges except when the 4-color ink set is used or except M and Bl ink
when 6-color ink set is used, printing or cleaning is stopped when an error occurs and the machine returns
to LOCAL mode.

Errors related to the amount of remaining ink
Calculate the number of ink shots by printing and flushing or the amount of ink sucked by cleaning and filling,
and then the amount of consumed ink by subtraction of remaining ink.
When the amount of remaining ink is updated, it is written into the ink IC chip.
A cartridge error is issued according to the amount of remaining ink.
No. Item Description
Error detect timing Limitations after error detection
1 Cartridge near end The amount of remaining ink is detected on the near
end detect PCB assy. The specified value of each
cartridge is as follows:
220 cc cartridge: 20 cc
440 cc cartridge: 40 cc
Initial filling is not allowed
Printing is allowed.
Cleaning is not allowed (only use-up
cleaning is allowed).
2Cartridge ink end Displayed when use of a certain amount of ink is
detected after the near end detection.
Neither printing nor initial filling is
allowed, but cleaning is allowed.
3 INK REMAIN ZERO
(Only for the 4-color ink set)
Displayed when the amount of remaining ink is
detected to be 0 cc after the ink end detection.
This error may be displayed only after
completion of ink use-up cleaning.
None of printing, initial filling and
cleaning is allowed.
4WRONG CARTRIDGE Occurs when the amount of consumed ink exceeds
nearly double (220 cc cartridge: 400 cc, 440
cartridge: 800 cc or more) the ink cartridge capacity
but the ink end is not displayed yet.
None of printing, initial filling and
cleaning is allowed.

1.3.3 Supply Cartridge Control and Selection
Supply cartridge control
Cartridge status indicated by LEDs
Selection and determination of the supply cartridge for the 4-color ink set
supply cartridge switching selection timing
At power-on
When an error occurs in the currently selected cartridge
When a cartridge with higher priority than the currently selected cartridge is inserted
 Switching is not executed during printing or cleaning but executed when the machine has returned to LOCAL
mode.
When there is more than one effective cartridge for 1-ink supply path
No. Item Description
1 For the 4-color ink set
M and Bl ink for the 6-color
ink set
The machine uses two ink cartridges for 1 supply system and can mount 8 cartridges in
total.
1 supply cartridge is assigned to 1 supply system. The cartridge with less amount of
remaining ink is used first by toggle switching.
Switching between cartridges for ink supply occurs under any of the following
conditions:
• “INK END” during printing
• “INK NEAR END” during filling
• Ink IC warning
• When the cartridge is removed
• When executing Ink use-up cleaning
2Except M and Bl ink for the
6-color ink set
For the 8-color ink set
For the 6-color +W ink set
For the 6-color +W ･Si ink set
Since there is 1 ink cartridge per supply system, all 8 cartridges are supply cartridges.
