2.2.4 Print Position Adjustment Function

0012-6248

This printer supports a print position adjustment function to adjust the vertical and horizontal print position and

the bidirectional print position of the print head mounted on the carriage and the feed rate.

Print position adjustment work in two modes: automatic adjustment, in which print position adjustment patterns

printed are detected by a multisensor 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 make print position adjustment, A4-or-larger-sized roll media or cut media are needed.

2.2.5 Head Management

0012-6249

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, open carriage cover detection, print start (check timing variable by

selecting Nozzle Check from the system menu)

2.2.6 Printhead Overheating Protection Control

0012-6251

When an abnormal temperature rise in the printhead is detected, overtemperature protection control launches.

Overtemperatures could occur in the printhead after a spell of print operations without the nozzles being filled

with inks.

Overtemperature protection control prevents non-discharge failures and damages that might result from an

overheated printhead.

overtemperature protection control is implemented on the basis of the temperature detected by the head

temperature sensor for each nozzle. When an abnormal temperature is detected in any nozzle train,

overtemperature protection control is exerted at one of two levels according to that temperature.

Protection level 1

If the head temperature sensor (DI sensor) has detected 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
