2.2.2 Operation Sequence at Power-off

Turning off the power switch cuts off the drive voltage supply, launching a firmware power-off sequence as shown below.
If the power cord is disconnected from the wall outlet or the top cover or any other cover is opened, the printer cancels the ongoing operation and shuts down
immediately. Since printhead capping may or may not have been carried out properly, reconnect the power cord to the wall out and turn on the power switch.
Making sure that the printer has entered online mode, turn off the power switch.

2.2.3 Print Control

a. Print modes
Print methods, such as carriage and paper feed operation, are varied according to the media type, print quality, kind of print data and so forth to achieve high-quality
high-speed print free from blurring and uneven density.
Because each color prints in up to 16 passes according the print quality requirement for a print mode, uneven density problems caused by variations in the rate of
discharge among different nozzles are eliminated. Deferred print timings do not allow a new ink to overprint the preceding ink until the preceding ink has virtually
fixed, thereby reducing the chances of blurred printing.
Different operations take place even in the same print mode according to the paper setting of the print driver.
(1) Draft mode
Imaging data are thinned out to print in one or two passes per band (equivalent of the length of a nozzle).
Select Draft as a print quality setting of the print driver to enable draft mode.
(2) Standard mode
Imaging data prints in one to six (one, two, four or six) passes per band (equivalent of the length of a nozzle).
Select Standard as a print quality setting of the print driver to enable standard mode.
(3) High quality mode
Imaging data prints in two, four or eight passes per band.
Select High as a print quality setting of the print driver to enable high quality mode.
(4) Highest quality mode
Imaging data prints in eight or 16 passes per band.
Select Highest as a print quality setting of the print driver to enable highest quality mode.
