| Q1．What is Ink Jet Printer?
|A1．Equipment to print by excluding ink. Basically similar to Ink Jet Printer used in the office. What we make and supply is the industrial printer
which is installed on production line and print on product or package directly.
Please use for high-mix low-volume production line.
| Q2．What is the advantage of Ink Jet Printer?
|A2．Shown by run of the item
●Products moving on the production line were printed by ejecting ink without
contacting and only ink is consumable.
●Control and setting of printing letters were done by special controller
though key board input. So anybody can operate easily without soiling his
●Many patterns of printing letters can be pre-set and can be switched by
key board input and external signal.
●Date, number, lot number and other information can be printed clearly
and easily. Our company prepares many grade of printer up to super high
resolution type of 500 dots
| Q3．What kind of Ink Jet Printer do you have? →Page Top
|A3．Please refer to following table.
※Printers for large characters print relatively large letters such as company
name, product name and lot number mainly on out side of carton box. Printers
for small letters print exp. date, date of packing and lot number on each
|Q4．Can bar code be printed on out side of package box? →Page Top
|A4．Our JET HQM, JET HQ500 type Ink Jet Printer have the capability of printing bar code. Printable bar codes are ITF,
Code39, JAN (only JET HQ500) and two dimensional QR type (only JET HQ500,HQM). Printed bar codes are useful to manage and logistics of products. Please
ask us about how to use.
|Q5．What is two dimensional bar code? →Page Top
|A5．What we have used is one dimensional code where lines of variety of
thickness are put in one direction and scan the order and thickness of
these lines. And the amount of data that can be stored in this bar code
is limited and only numbers are recorded. On the contrary, two dimensional
bar code can store much more information by arraying codes vertically and
horizontally and this code can store not only code but product name, specification,
information of maker and delivery using kanji. It can correct error and
can be scanned any direction then flexible logistic systems can be established.
And this bar code is expected to get more and more popular from now on.
Our company's Ink Jet Printer can print QR code. (JET HQ500, JET HQM)
|Q6．What is on demand type? →Page Top
|A6．As ink is ejected only when ejection signal was received, we call these
type as on demand type. This type applied to Ink Jet Printer which are to print relatively large type of letters on the package box.
This type is economical and has good printing property. For ink is always
on the nozzle, quick dry type ink harden easily. So usually slow dry ink
is used for this type. Though this doesn't cause problem when carton is
printed, quick dry ink can not used on plastics or metal.
|Q７．What is valve type →Page Top
|A７．This is one of on demand type and ejection of ink is controlled by valve.
Ink is delivered by pomp to the top of the nozzle but it doesn't eject
usually because the valve is shut. When the signal was sent valve opens
and ink ejects. Because of high pressure, ejection is powerful distance
to the object can be longer and size of ink drop can be larger. Valve need
to have a certain size and difficult to move quickly. So this technology
is used for low dots basic type printer. The dots consisting letters can
be seen by eyes. This type can print alpha-numeral such as code and number.
And kanji can not be printed.
|Q8．What is Piezoelectric element driving? →Page Top
|A8．This is one of on demand type utilizing Piezoelectric element which
is a ceramic that expands and contracts according to electrical potential.
Ink tank and nozzle are kept at the same height to balance the pressure.
Ink is always at the top of nozzle and surface tension prevents leaking
of ink. With electric potential piezoelectric element contract and expand
and ink is ejected as squirt gun. Nozzle diameter can be small and fine
control is possible. And this type is suitable for printing high quality
letters. We have explanatory booklet of following printers of this type
■JET HQL (32 Nozzles : 7 Holes/Nozzle)
■JET HQC (32 Nozzles : 2 Holes/Nozzle)
■JET HQM (32 Nozzles : 3 or 6 Holes/Nozzle , 128 Nozzles : 1 or 2 Holes/Nozzle)
■JET HQE (32 Nozzles : 1 , 2 or 6 Holes/Nozzle)
■JET HQ500 (500 Nozzles : 1 Hole/Nozzle)
■JET HQ256 (256 Nozzles : 3 Holes/Nozzle)
Printers which have more holes (from which ink ejects) than nozzle has
multiple holes at on nozzle. Control is done
|Q9．What is continuous type? →Page Top
|A9．When metal, glass and plastics products are printed, quick dry ink must
be used. But this type of ink hardens when it is used for on demand type.
So ink is continuously ejected during operation and printing is controlled
by changing the path of ejection. Ink is withdrawn the moment it is not
needed. Ink is forced to eject by pomp and vibration of piezoelectric element
makes ejecting ink small drops. Ink regularly goes into retrieving hole
to be retrieved. When the printing sign arrives ink drop is charged. This
charged ink drop path is altered by electric field in front of nozzle and
inducted ink drop to the place tobe printed (Charging induction). Because
printing is done by changing angle of the path of ink, letter size is depends
on the distance between nozzle and object. And ejecting ink by pressure
is not affected by the distance and printing curved surface is possible.
This type is widely used for such as can for drink and tube etc. JET CCS was developed in this type
|Q10．What is multi heads? →Page Top
|A10．Ink Jet Printer is consists of controller, ink unit and head. Multi head is the printer
which controller was improved to be able to control multiple heads and
ink units. Different printing pattern can be set for each head.
|Q11．What kind of letters can be printed?
|A11． Piezoelectric element driving type HQ series, continuous type and
JETCCS can print alpha-numeral, symbol, hiragana, katakana, kanji(JIS first and
second standard) and user registered letters, in several kinds of dot letter
up to 32 dots. Economic type JET HQL can print 48 letters of user registered kanjibin addition to alpha-numeral,
symbol, hiragana and katakana. JET HQ500 , HQ256 can print all True Type fonts as it is based on PC.
|Q12．Can information other than letters be printed? →Page Top
|A12．Continuous type of JET CCS , economy type of JET HQC type can print only letters. Piezoelectric element driving type HQ series
can print bar code and two dimensional bar code in addition to letters.
JET HQ500 can import graphic from PC and print it. JET HQ500 is based on PC and can print unlimited graphics like PC printer by importing
any bit map up to 500 dots in vertical direction. JET HQ256 is also based on PC and able to print unlimitedly.
|Q13．Can size of letters be changed? →Page Top
|A13．Continuous JET CCS ejects ink drop adjusting the angle of its path. So the size of the letters
is changed by distance between nozzle and object. On demand type adjust
height of letters by inclining head. Letters gets smaller and high density
printing is possible with large inclination. Heads of JET HQ500 , JET HQ256 are always vertical and size of letters can be specified within range
of dots specified for each printer.
|Q14．Can plane carton boxes be utilized?
|A14．To prepare pre-printed boxes for each product needs much cost, trouble
and space. Printing on plane (or only common items are printed) case at
the point of packing is a good solution. This method requires high accuracy
but HQ series meet this requirement. And the cost is much lower than labeling. Especially
JET HQ500 and JET HQ256 have overwhelming expression of such as logo, barcode and graphics and
eliminate the necessity of pre-printed case. This solution can reduce much
|Q15．How to tell the timing of printing? →Page Top
|A15．The timing of printing is decided by the signal which is projected
by photo sell set near the head. Vertical printing position is decided
by the position of the head and horizontal position is can be decided unlimitedly.
Specially customized version such as auto shifting function of head for
printing on shapeless object or head transferring system for static object
can be designed and developed on your demand.
|Q16．How to clean up quick dry ink? →Page Top
|A16．JET CCS type which uses quick dry ink equipped with auto capping function
to seal the nozzle automatically at the end of operation. So it doesn't
need clean up (including auto clean up). It has also interval function
which automatically circulates ink at the same interval. So it is surely
free from nozzle plugging even in a long non-operation period. On demand
type JET HQ series need just need to wipe the nozzle surface.
|Q17．How printing contents are set? →Page Top
|A17．It can be set at any time by key entering on flat key attached to the
controller. As for JET HQ500 , JET HQ256 , graphic can also be set freely. And this printing content can be stored
and referred on PC.
|Q18．Can printing contents be switched easily? →Page Top
|A18．Easy switching of printing contents is one of the features of Ink Jet Printer. The switching is done by flat key attached to the controller. This flat
key is sealed type of key board box. Printing patterns of all heads can
be controlled by one key board. Switching can be automatically done by
external signal on the line where various kinds of products are conveyed.
RS232C is usually used as interface but other interface can also be used.
JET HQ500 and JET HQ256 are controlled by PC. We can customize also external control.

|Q20．How to print exp. date →Page Top
|A20．Exp. date is calculated from offset from the day of packing.
When unit of offset value is only "day", the value is simply
add to the day of packing regardless of month. When unit of offset value
are only "month" and "day", there is a case non-existing
date is calculated. (Feb. 30th etc.) In this case, select one of following
3 calculating method in advance.
●"End of the month"：When non-existing date is calculated, exp.
date is set to be the end of the same month. (2/30→2/28)
●"Carry over"：Exp. date is carried over to existing date in next
month (2/30→3/2) ●"Beginning of next month"： Exp. date is set
to be the first day of the next month. (2/30→3/1)
Please set offset value (the span when the product is good) which calculated
for each product.
|Q21．When variety of products are conveyed, can these be printed?
|A21．If different products are sometimes conveyed, it can be set by flat
key input. But if products conveyed randomly, setting is troublesome. So
in this case, controlling by external signal is convenient.
In large system, printing contents are switched by computer which controlling
And printing contents can also be selected by scanning bar code which is
labeled on each product.
|Q22．What is ink consumption? →Page Top
|A22．Ink consumption by inkjet printer is extremely small because just the
amount of ink necessary for printing is ejected and there is no loss at
during the process.
JET HQM can print 10 and several thousand 32 dots letters by 1cc, though it vary
a little depend on head, dot/letter, thickness, ink and so on. Since the
consumption is proportional to area, 4 times of that number of 16 dots
can be printed.
|Q23．What is the fastest line it can print? →Page Top
|A23．One of the features of Ink Jet Printer is fast printing as well as high quality. Up to 200m/min is possible.
Though line speed can be set by flat key, actual line speed can be detected
by sensing device. This is recommended when the line speed is changeable
|Q24．Can it print an motionless object? →Page Top
|A24．Ink Jet Printer is controlled Y-axis, X-axis depends on movement of object. So it can
not print on motionless object. But when product is too large to move at
the same speed by conveyer, printing is possible by moving head. This head
moving equipment can move to two directions. One is to product and the
other is printing direction.
Since this must be designed individually to be suitable for each object,
please ask us
|Q25．What is quality of printing? →Page Top
|A25．Generally quality of inkjet printing is depends on its resolution.
Therefore the more nozzles head has, the higher quality letters are.
In usual use 32 dots printer such as JET HQM has enough quality. But when higher quality is required 64 dots, 256 dots
or 500 dots printers are recommended. JET HQ500 has overwhelming dots number of 500 dots and realize high quality of 180
|Q26．Can it print on wood or materials for outer wall? →Page Top
|A26. Ink Jet Printer is used for many materials such as pre-cut woods, rolled paper, sheet-like
products or sacks in addition to packing box such as carton box.
As line systems expand, these are the field where Ink Jet Printer which can switch printing contents for each product work effectively.
|Q27．What is daily maintenance? →Page Top
|A27．Both on demand type JET HQ series and, Continuous JET C series type don't need daily maintenance.
To avoid trouble, only daily cleaning is needed. Please refer to explanatory
