2.2.4 Print Position Adjustment Function
0012-6313
This printer supports a print position adjustment for the vertical and horizontal print positions, the bidirectional print position of the printhead mounted on the car-
riage, and the feedrate.
There are two adjustment modes for the print: automatic adjustment, in which print position adjustment patterns printed are detected by the multi sensor attached
to the lower left part of the carriage, and manual adjustment, in which print position adjustment patterns that are slightly modified from one another are printed, so
that visually verified adjustment values can be set from the operation panel.
To execute the print position adjustments, 10-inches size or larger roll media or two sheets of A4/LTR-size or larger cut sheet are needed. However, in case of A2-
size or larger cut sheet, one sheet is needed.
The print position adjustment function is executed by the following menu.

2.2.5 Head Management
0012-6314
This printer supports a nozzle check function to spot non-discharging nozzles in the printhead.
When the printer detects a non-discharging nozzle, it starts cleaning the printhead automatically to correct its discharge failure. If cleaning does not work, the printer
backs up the non-discharging nozzle with an alternative nozzle automatically to ensure unfailing print performance.
Detection timings (automatic):
Power-on, carriage cover open detection, print start (check timing variable by selecting Nozzle Check from the system menu).
2.2.6 Printhead Overheating Protection Control
0012-6315
When an abnormal temperature rise in the printhead is detected, overheating protection control launches.
Overheating could occur in the printhead after a period of print operations without the nozzles being filled with inks.
Overheating protection control is implemented on the basis of the temperature detected by the head temperature sensor for each nozzle. When an abnormal temper-
ature is detected in any nozzle train, overheating protection control is exerted at one of two levels according to that temperature.
Protection level 1:
If the head temperature sensor (DI sensor) detects a temperature higher than the protection temperature, it halts the carriage temporarily at the scan end position in
the direction of travel according to the carriage scan status.
Printing resumes when the printhead radiates naturally to cool down below a predetermined temperature or when 30 seconds or longer have elapsed since the de-
tection of the higher temperature.
Protection level 2:
If the head temperature sensor (DI sensor) detects a temperature higher than the abnormal temperature, the printer shuts down the print operation immediately,
moving the carriage to the home position for capping, with an error indication on the display.
2.2.7 Pause between Pages
0012-6320
An inter-page function is available to prevent ink rubbing, which keeps paper just printed hanging above the platen and waiting for a predetermined period of time
before delivery.
The wait time is user-programmable from the print driver. This feature is particularly useful on paper that takes time to dry after printing, such as film.
2.2.8 White Raster Skip
0012-6322
This printer supports a white raster skip function to bypass carriage scanning in a consecutive sequence of voids in print data, for added throughput.
2.2.9 Sleep Mode
0012-6324
The printer has sleep mode to reduce its standby power requirement.
The printer transitions to sleep mode automatically when it has been left idle or no print data has been received for a predetermined period of time while the printer
is online or offline.
The printer exits sleep mode when any operation panel key is activated or print data is received from the host computer.
The time to transition to sleep mode is variable from the operation panel (Default: 5minutes).
2.2.10 Hard Disk Drive
0013-9239
This printer features a hard disk drive, which provides the following functions.
- Early release of the host computer
- Error recovery
