IP-7900/7700 or IP-7900-02/7700-02 Advanced Operation Guide
Change the automatic cleaning timing
To ensure the print heads’ proper condition, the Printer performs the automatic cleaning. The cleaning mode
can be specied depending on the preset media. Select the DURING PRINT or DURING PRINT2 depending on the
media characteristics.
Based on the past print operation history, the Printer performs the automatic cleaning:
- On starting and completing the print operation; and
- During the print operation
When the Printer performs the cleaning during the print operation, the cleaning is started only
after completing the current band’ s print.
This mode is recommended when printing on the media subject to the heater temperature, for
example, on Vinyl.
After the cleaning, the Printer starts the rest of the interrupted print job.
Some media shows misalignment at the linkage of the prints before and after the cleaning. In such
a case, START & END or DURING PRINT2 is recommended.
Based on the past print operation history, the Printer performs the automatic cleaning on starting
and completing the print operation.
Note that the automatic cleaning is not performed during the print operation.
Based on the past print operation history, the Printer performs the automatic cleaning:
- On starting and completing the print operation; and
- During the print operation
When the Printer performs the cleaning during the print operation, the cleaning is started by
suspending the current band’ s print.
This mode is recommended when printing on the media less subjected to the heater temperature,
for example, on Banner.
After the cleaning, the Printer starts the rest of the interrupted print job.
This mode shows less misalignment at the linkage than the DURING PRINT. However, the hue after
the cleaning may be dierent from the one before the cleaning.
START & END
DURING PRINT
DURING PRINT2
Current print band
On starting and completing the printer operation, the Printer does not perform the automatic
cleaning, but only after filling the cap with ink (fillcap) the Printer performs it.
Note that the Printer never performs the automatic cleaning for ensuring the print heads’ good
condition. So, at a nozzle clogging, manually perform the normal cleaning.

IP-7900/7700 or IP-7900-02/7700-02 Advanced Operation Guide
With inkjet printers, a horizontal banding may appear between the bands, which are the areas printed by one
scan. This symptom is called as banding.
The banding is caused mainly by setting the media advance compensation improperly. With the proper
compensation, the bands are linked without gap. However, with the larger compensation the bands are linked
with gaps, showing white lines, while with the smaller one the bands overlap, showing black lines.
The banding is also caused in the following cases.
- The ink dries so slowly.
- The media advance changes considerably depending on the print head scan.

Black banding at incorrect media advance
The Smart Pass Technology is the function to reduce this banding problem.
With the Printer’s operation menu, this function is available by selecting
the LOW, MEDIUM, HIGH, FINE GRAIN, or HIGH, LESS SPRAY at "#IMAGE
IMPROVE" of MEDIA REG MENU.
With Smart Pass Technology, the bands are printed with overlapping
even when the media advance compensation is proper. In the LOW, the
overlapping part is processed with the SIIT’s unique algorithm so that the
part is not notable where the dierence between the overlapping part and
the rest are minimized.
The modes MEDIUM, HIGH, FINE GRAIN, and HIGH, LESS SPRAY enlarged
the overlapping parts and added the function to reduce the color density irregularities and white lines. This
function allows the print performance with higher quality and more stabilization than the previous ones.
NOTE
(1) In the LOW, with some print data, the overlapping part is light or blurred. Select the MEDIUM, HIGH, FINE GRAIN, or HIGH, LESS
SPRAY to reduce this symptom.
(2) In the HIGH, LESS SPRAY, the carriage speed is low.

IMAGE IMPROVE Description
Tolerance for
media advance
misalignment
Remark
OFF Banding is not reduced. None* Even with the accurate media advance,
the slippery media may show banding.
LOW Banding is reduced. Small Even if the media advance is not
accurately correct, the modes LOW,
MEDIUM, HIGH, FINE GRAIN, and HIGH,
LESS SPRAY show the banding-free
printout. The modes also reduce the
slight variation even with the slippery
media.
However, note that the printout
is defective if the media advance
misalignment exceeds the tolerance.
So, to some extent, adjust the media
advance compensation.
MEDIUM Banding is reduced. Select this mode if
the image quality is not improved with
the LOW.
Medium
HIGH, FINE GRAIN
Banding is reduced. Select this mode if
the image quality is not improved with
the LOW and MEDIUM.
Large
HIGH, LESS SPRAY
Banding is reduced. Select this mode to
improve the problems below:
- Bleeding is found; or
- The image edge is not sharpened. As a
result, the image is soft-focused.
Small
* Set the value accurately.

Procedures
Adjusting media advance compensation
Compensate the media advance adjustment value with:
- [SIMPLE] media advance adjustment pattern; or
- [ROUGH] and [DETAIL] media advance adjustment pattern
The [SIMPLE] media advance adjustment pattern relatively reduces the media amount required to print the
adjustment pattern, while [ROUGH] and [DETAIL] media advance adjustment patterns assist you to compensate
the media advance adjustment value more accurately.
If you intend to change the media advance compensation during the print, see the procedure on the page 44 .
With the Smart Pass Technology…
- Select [SIMPLE] so that you can change the media advance compensationwhile the Printer prints the
media advance adjustment pattern in the mode set at "#IMAGE IMPROVE" of MEDIA REG MENU.
With [ROUGH] and [DETAIL] media advance adjustment pattern, the Printer always prints the media
advance adjustment pattern in the OFF mode of "#IMAGE IMPROVE."
The factors that change the media advance
compensations are as follows.
- Change the print mode
- Change the pressure with the pressure control know.
- Print with/without the take-up reel unit
- Change the media type
- Change the media advance path
Compensate the media advance with SIMPLE media advance adjustment pattern
To compensate the media advance, determine the adjustment value with the SIMPLE media advance adjustment
pattern. The length of one SIMPLE media advance adjustment pattern is 2-5mm depending on the print mode.

How to analyze the media advance adjustment pattern [SIMPLE]
Analyzing the SIMPLE media advance adjustment pattern is explained using an example of 8-color mode
printout.
In case of small media advance
compensation
In case of appropriate media
advance compensation
In case of large media advance
compensation
In Lc, Lm, Gy, and Lg, the horizontal
lines and the stripe bar’s bottom
are misaligned downward, because
the adjustment value is smaller.
All horizontal lines are aligned in one
line, and the color stripe bar’s
bottom is also aligned in one line
when the adjustment value is proper.
In Lc, Lm, Gy, and Lg, the horizontal
lines and the stripe bar’s bottom
are misaligned upward, because
the adjustment value is larger.

How to analyze the media advance adjustment pattern
Analyzing the media advance adjustment pattern is explained using an example of black (K) color.
In case of small media advance
compensation
In case of appropriate media
advance compensation
In case of large media advance
compensation
When observing the horizontal
lines, if the splices of paths are
overlapped (dense), the media
advance compensation is small.
When the splices of paths are not
overlapped and even, the media
advance compensation is
appropriate.
When the splices of paths are
separated (light), the media
advance compensation is large.
