areas.
TOXIC HAZARD.The cleaning agent is poisonous if taken internally.Do not drink.Seek
medical attention immediately if ingested.
Caution Notices
Caution
EXCESSIVE USE OF TOP-UP OR SOLVENT.As solvent is used during the stop
cycle,repeatedly stopping and starting the printer can lead to excessive use of top-up or
solvent and may lead to a Mixer Tank High error and low ink viscosity.
QUICK STOP.After a Quick Stop,the machine should not be left in this state for any
length of time as drying ink may make restarting difficult.
EQUIPMENT DAMAGE.Do not fit or remove any connector on the printer whilst power
is on,otherwise the printer may be damaged.
CLEANING MATERIALS.To avoid damage to the printer components use only soft
brushes and lint free cloths for cleaning.Do not use high pressure air,cotton waste or
abrasive materials.
EQUIPMENT DAMAGE.Ensure that the cleaning agent is compatible with the ink used
before carrying out printhead cleaning otherwise the printhead may be damaged.
EQUIPMENT DAMAGE.The printhead must be completely dry before attempting to
start the printer otherwise the printhead may be damaged.
RISK OF DATA LOSS.All messages apart from the(TEST MESSAGE)will be deleted
when you select the Delete All Messages option.

Basic Operation
This section contains the following operating instructions:
• Steps of switch the printer on;
• Steps of switch the printer off.
Start-up Procedure
1. Carry out the daily visual inspection
2. Check that the electrical supply for the printer is available
3. Press the mains power button to switch the printer on.
4. After the printer has initialized the Quick screen is displayed.
Start Jet
Press F1 to start jet.In this process the printer will carry out the operation of auto-
matic cleaning, which can take up about 2 minutes.Printing commences automatically
after the jet start sequence finishes and the product sensor is triggered.
Monitoring Printing
When the printer is running you can monitor its status using:
• The status icons on the display.SSSSSS
• The LEDs on the keypad.
• The optional lamp stack(if fitted).
Stop Jet
Press F1 to stop jet. DO NOT switch the printer off until the flushing cycle is
complete. The default stop sequence is Clean Stop,but Quick Stop can be selected.
1. Stopping jet needs about 4 to 5 minutes.After the printer finishes automatic
cleaning,it will be not running.
2. Do not frequently start jet and stop jet in a day.Otherwise, it will trigger alarm of
“Mixer Tank Level Too High” and “Ink Viscosity Too Low”so that the printer can not
run normally.
3. The operation of Quick Stop should be under the guidance of maintenance
engineer lest the ink supply system is jammed with ink.
Power Off
After the cleaning process for jet-stopping is complete,press the power button to power
off.
Every time the jet is started or stopped, the printer will automatically clean its
printhead,which takes up about two to five minutes.When the screen appears “Jet is not
running”,you can power off.Otherwise, the ink system will be jammed with ink.
Special Note:If the printer has not been used for over one week, after the normal
procedure of starting jet is complete,enter the System menu and select Nozzle
Flush,and then carry out manual cleaning.This operation helps to lengthen its
lifespan.

The System menu allows you to set modulation and phase parameters.These parameters
control the nozzle vibration,which must be adjusted to compensate for change in ink
temperature and viscosity. (This operation is carried out by maintenance engineers or
with the assistance of engineers)
Note(The following operations can only be carried out with the permission of
maintenance engineers):
1. If you need to switch off the printer temporarily,and the close time is less than half
an hour,you can use Quick Stop Jet.
19
LT710 Printers Instructions for Use
2. If you use the printer normally,and it is no more than half an hour from the last
shutdown time,you can use Quick Start Jet.
3. If you use the functions above,when starting jet there is a risk of the printhead
components being covered with ink,and it needs manual cleaning.
Abnormal Stops
Abnormal stops will normally use the Quick Stop Jet for reasons of speed and safety.
Maintenance operations should normally use Quick Stop Jet.However,the last stop of a
maintenance sequence should be Nozzle Flush,to prepare the machine for normal ope-
ration.
If a previous stop was due to an abnormal condition,a message is displayed at startup.
This message will only clear after the printhead has been inspected.
The software will automatically default to Quick Stop Jet(with a visual warning) under
the following conditions:
• The mixer tank is full.
• Viscosity is too low.
The Data menu shows you software information, run hours, product counter, reset run
hours and etc.
Modulation parameters can be set from the Calibrate menu.This menu can also access
the interface of current system status.(Look at Page 8 “Calibrate Menu”)
This screen shows the current value of various parameters to

5.1 Maintenance
*The actual interval depends on operating conditions and is set at the time of
installation.
Visual Inspection
The following inspections should be performed daily.
Cabinet and Cables
1. Inspect electrical cables and connectors for signs of damage or wear.
2. Inspect the printer cabinet and umbilical cable for signs of damage,wear or
ink leakage.
3. Report any faults to a maintenance engineer.
Printhead
1. Stop the ink jet and disconnect the printer from the mains supply.
2. Release the knurled screw on the printhead by turning it anticlockwise.
3. Remove the printhead cover.
4. If any ink deposits are evident,then clean the inside of the cover.
5. Inspect the printhead and the inside of the printhead cover for any build up of
ink deposits.Clean if necessary.
Cleaning
Cleaning the Printhead
Thanks to the unique clean stop/start system,the printer will operate for a considerable
time before the printhead requires cleaning.However optimum performance and system
reliability will only be maintained if the printhead is cleaned regularly and it should be
inspected daily.
1. Set the mains power button to the off position and disconnect the mains supply
lead.
2. Loosen the knurled screw and check the printhead for a build up of ink
21
LT710 Printers Instructions for Use
deposits.
3. Where necessary use a cleaning agent compatible with the type of ink being
used and tissue or a soft brush to clean the printhead.
4. Allow the printhead to dry and ensure that the slot in the charge electrode is
clear of cleaning agent.
5. Refit the printhead cover and tighten the knurled screw.
Cleaning the EHT Block
To prevent build up of conductive pigment,clean the contoured surfaces of the EHT
block.Use tissue and solvent or a soft brush from the recommended cleaning kit.
Cleaning the Printer Cabinet
Periodicity-weekly.
Remove dust from the printer using a vacuum cleaner or soft brush.
Wipe the outer surfaces of the printer using a damp lint free cloth.A mild detergent can
be used to remove stubborn contamination.
Ink and Top-Up Reservoir Replenishment
Periodicity-when indicated on the display
1. Open the ink system compartment door as required.Change the solvent box (on the
right side) or the ink box(on the left side).
2. Check that the part number of the ink or top-up specified on the label corresponds
to that displayed on the printer display.
5.2 Troubleshooting
Print Incomplete
Check that the Printed Dots value set in the Message Parameters menu is equal to the
maximum number of dots required for a raster(26/34 maximum) 。 See “Setting
Message Parameters”at Page 12.
Check the printhead for ink deposit build-up and clean is required.
Mixer Tank The mixer tank level is empty.The printer will stop
Empty immediately the icon appears.Report the fault to a
maintenance engineer.
The printer cabinet has overheated.To prevent damage,
Cabinet Too Hot the printer shuts down automatically.The printer can be
restarted after it has cooled.
Report all overheating incidents to a maintenance
engineer.
