■Edit message
This function is used to enter characters as print
contents. It is called up from the print description
screen. In addition to fixed characters, calendar
and count characters are entered here.
■Edit standard pattern
A function of arbitrarily editing a dot pattern of
the standard characters (alphabetical characters,
numbers and symbols). Start it from the auxiliary
function menu.
■Excitation frequency
Excitation voltage frequency.
■Excitation setup update
This function changes the excitation setting. Start
it while you are on the maintenance menu.
■Excitation voltage
This voltage is applied to a device that converts
electrical vibrations to mechanical vibrations.
The resultant vibrations cause the nozzle to
oscillate, thereby atomizing the ink.
■Excitation V-ref.
The span between the maximum and minimum
excitation voltage values is divided into 20
segments, which are then designated 0 through
19. One of such 20 values is referred to as the
excitation voltage value.
■Fault
An error that inhibits the printer from continuing
to make prints. If a fault occurs while the printer
is ready for printing, the deflection voltage sup-
ply is shut off.
The ink ejection operation may stop or continue
depending on the type of the fault.
→ (cf.) Warning
■Faulty state
State in which a fault exists.

F
■Heating unit
This unit functions to maintain the ink
temperature at an appropriate level.
■High-speed printing
When the character size setting is 5×7 dots, and
print line is set to 2 or 3 lines, three modes: HS,
MS or LS can be selected with the setting of
particle use rate 1/1. By selecting the mode, you
can get the almost the same print quality as
particle use rate setting 1/2 for the line that you
can't set to the particle use rate 1/2 and should be
set to 1/1 at the previous software.
■Ink drop use percentage
The ratio of flying ink particle use. When a ratio
os 1/3 is selected, one out of every three particles
will be used for printing, with the remaining two
particles unconditionally recovered from the
gutter.
This value is saved together with the print data.
■ Ink stream position
The ink position prevailing within the gutter bore
when the ink particle flow reaches the gutter with
no deflection voltage applied. If the ink stream
position does not coincide with the optimum
position, illegal printing or ink spillage from the
gutter may result.
■<Insert> key
In a character input sequence, this key is used to
switch between the insertion and overwrite
modes.
■<Invert dot> key
While the create user pattern screen is displayed,
this key is used to reverse the dot at the current
cursor position.
■Line
One line of print items that comprise a column.
The lowermost line is line 1.
