2.4 Print Position Adjustment

For instructions on how to perform print position adjustments, see
menu.
2.4.1 Print position adjustment
This printer incorporates a print position adjustment function for manual adjustment of the
vertical/horizontal positions, bidirectional printing position, and sheet feeding rate of the
printhead installed on the carriage.
The print position is adjusted by first printing the print position adjustment patterns with
slightly modified conditions and setting the adjustment values observed visually from the
operation panel.
The print position adjustment requires a roll media or cut sheet that is A3 size or larger.

2.5 Overheating Protection Control of Printhead

This printer is provided with an overheating protection control function that detects abnormally
high temperatures in the printhead.
The printhead can overheat, for instance, when the printing process continues for some
time with no ink supplied to the printhead nozzles. The overheating protection control
function prevents a printhead nozzle from becoming permanently clogged or damaged
due to excessive heat.
The overheating protection control process is based on the detected temperature of the
head temperature sensors in each nozzle array. If overheating is detected in a single
nozzle array, control is performed in one of the two stages below according to the
temperature.
Protection level 1:
If the head temperature sensor detects a temperature above 80°C, the printer allows
the carriage to continue in the direction of its scanning pass and then stops it at the
scan end position. The wait control is activated to allow the heat to dissipate.
Printing resumes when the temperature drops below 80°C.
Protection level 2:
If the head temperature sensor detects a temperature above 110°C, the printer
immediately stops the printing operation, and the carriage returns to the home
position where capping is performed. An error message is shown on the display.
2.6 Pause between Pages
To prevent ink blots from forming, this printer discharges printed pages so that they
hang down from the platen and dry and is provided with a Pause between Pages
function for discharging sheets after a specified wait time. The user can set the wait
time from the printer driver. This function is particularly useful for film-type and other
sheets that need extra time to dry.
For borderless printing, 30 second drying time is set automatically.

2.7 White Raster Skip

To improve the printing throughput, this printer incorporates a White Raster Skip
function for skipping the carriage scan operation for continuous blank segments of
print data.

2.8 Sleep Mode

This printer has a Sleep mode for reducing the standby power.
The printer automatically enters Sleep mode (Power Save mode) when there are no user
operations and no print data has been received for a preset period of time in the Online
or Offline mode. The printer wakes from Sleep mode whenever the user performs any
key operations on operation manual or print data is received from the host computer.
The time until the printer enters Sleep mode can be changed from the operation panel.
