*1 The print engine may automatically select 1-way printing depending on the printing image type (graphic image, etc.). The printing direction can be selected

using the printer driver.

2.2.4 Print Position Adjustment Function

This printer has a printing position adjusting function to adjust the lateral and longitudinal printing positions and bidirectional printing position of the printhead

mounted on the carriage as well as the media feed amount.

The printing position can be adjusted in two ways: "automatic adjustment" by which the multi sensor installed at the lower left of the carriage reads the printing

position adjusting pattern and "manual adjustment" by which a print position adjusting pattern is printed with the printing conditions changed little by little to allow

the user to enter the visually checked adjustment value from the operation panel.

Printing position adjustment requires A4-size or larger roll media or cut sheet.

2.2.5 Head Management

This printer has a nozzle check function to detect any non-discharging nozzle. When a non-discharging nozzle is detected, the printer performs the print head clean-

ing operation. If the problem persists after completion of the print head cleaning operation, the non-discharged nozzles are automatically backed up by other nozzles.

Detection timing (auto):

Non-discharging nozzles are checked at the following timings:

- Power-on

- When the carriage cover is opened

- When printing starts (The check timing can be changed by selecting System Setup > Nozzle Check from the main menu.

2.2.6 Printhead Overheating Protection Control

This printer performs printhead overheating protection control when an abnormally high temperature is detected in the printhead.

The printhead can overheat, for instance, when the print operation continues for some time with no ink supplied to the nozzles.

The overheating protection control function prevents a print head nozzle from becoming clogged or damaged due to excessive heat.

Overheating protection control is performed based on the temperatures detected by the head temperature sensors in the nozzle arrays. If overheating is detected in

a single nozzle array, overheating protection control is performed at either of the following levels according to the temperature.

Protection level 1:

If the printhead temperature sensor detects a temperature above the limit, the carriage stops at the scan end position printer in the direction of travel according to

the carriage's scan status.

Then, wait control is performed to allow the printhead to cool naturally. When the printhead temperature drops below the prescribed value or 30 seconds have lapsed

since detection of the abnormal temperature, printing resumes.

Protection level 2:

When the head temperature sensor detects an abnormally high temperature, printing stops immediately, the carriage is moved to the home position, and the printhead

is capped. In this case, an error code is shown on the display.

2.2.7 Pause between Pages

To prevent ink blots form forming, this printer has a "pause between pages" function to hang down the printed paper from the platen to dry it and delivers it after

lapse of the specified wait time.

The user can set the wait time using the printer drive. This function is particularly useful for printing on film-type sheets that requires extra long time to dry.

For borderless printing, 30 seconds of drying time is automatically set.

2.2.8 White Raster Skip

To improve the printing throughput, this printer has a white raster skip function to skip the carriage scan operation for continuous blank segments in print data.

2.2.9 Sleep Mode

This printer has a Sleep mode to reduce the standby power.

The printer automatically enters the Sleep mode (Power Save mode) when neither user operation nor data reception occurs for a preset period of time in the online
