2 Safety Instructions

2.1 General Safety Instructions

 Keep the area around the device clean during and after

maintenance.

 Work in a safety-conscious manner.

 Store dismantled device parts in a safe place while maintenance

is being performed.

CAUTION!

The drawing in of items of clothing by moving parts can

lead to injuries.

 If possible, do not wear clothing which could be

caught by moving device parts.

 Button or roll up shirt or jacket sleeves.

 Tie or pin up long hair.

 Tuck the ends of scarves, ties and shawls into your

clothing or secure them with non-conductive clips.

DANGER!

Risk of death from increased flow of current via metals

parts which come into contact with the device.

 Do not wear clothing with metal parts.

 Do not wear jewellery.

 Do not wear glasses with a metal frame.

If a possible danger to your eyes is present, wear protective goggles,

especially in the following cases:

• when knocking in or knocking out pins and similar parts with a

hammer

• when using an electric drill

• when using spring hooks

• when loosening or inserting springs, snap rings and gripping rings

• when soldering

• when using solvents, cleaning agents or other chemicals

WARNING!

Risk of injury in case of missing or faulty protective equipment.

 After performing maintenance work, attach all safety

equipment (covers, safety precautions, ground cables etc.).

 Replace faulty parts and those which have become unusable.

The direct print module is designed for power supply systems of

110 V AC … 230 V AC. Connect the direct print module only to

electrical outlets with a ground contact.

Couple the direct print module to devices using extra low voltage only.

Before making or undoing connections, switch off all devices involved

(computer, printer, accessories etc.).

Operate the direct print module in a dry environment only and do not

get it wet (sprayed water, mist etc.).

Do not operate the direct print module in explosive atmosphere and

not in proximity of high voltage power lines.

Operate the direct print module only in an environment protected

against abrasive dust, swarf and other similar impurity.

Maintenance and servicing work can only be carried out by trained

personnel.

Operating personnel must be trained by the operator on the basis of

the operating manual.

Depending on use, ensure that clothing, hair, jewellery and similar

personal items do not contact the exposed rotating parts and/or the

moving parts (e.g. print carriage).

NOTICE!

With the open printing unit (due to construction) the requirements

of EN 60950-1/EN 62368-1 regarding fire protection casing are

not fulfilled. These must be ensured by the installation into the end

device.

The print unit and parts of it (e.g. motor, printhead) can get hot during

printing. Do not touch the printhead during operation. Cool down the

print unit before changing material, removal or adjustment.

Never use highly inflammable consumables.

Carry out only the actions described in these operating instructions.

Any work beyond this may only be performed by the manufacturer or

upon agreement with the manufacturer.

Unauthorized interference with electronic modules or their software

can cause malfunctions.

Other unauthorized work or modifications to the direct print module

can endanger operational safety.

There are warning stickers on the direct print modules that draw your

attention to dangers. Therefore the warning stickers are not to be

removed as then you and others cannot be aware of dangers and may

be injured.

CAUTION!

Two-pole fuse.

 Before opening the housing cover, disconnect the

printing system from the mains supply and wait for a

moment until the power supply unit has discharged.

2.2 Safety Handling when Working with Electricity

 The following work may only be performed by instructed and

trained electricians:

• work on the electrical assemblies

• work on the device while it is open and connected to the

power supply.

 Locate the emergency-stop or power switch so that it can be

actuated in case of an emergency.

 Unplug the device from the electrical outlet before performing

the following work:

• removing or installing power supply units

• working in the immediate vicinity of exposed power supply

parts

• mechanical inspection of power supply parts

• modifying the device circuits.

 Ensure that the device is de-energized.

 Check the workplace for possible sources of danger, e.g. moist

floors, defective extension cables, faulty protective conduction

connections.

 Give another person the task of remaining near the workplace.

This person must be familiar with the location and operation of

the emergency-stop and power switches and switch off the

power if danger arises.

 Use only one hand while working on electrical circuits when a

device is switched on. Hold the other hand behind your back or

put it in your jacket pocket.

This prevents the electricity from flowing through your body.

 Do not use worn or damaged tools.

 Use only tools and testing equipment that is suitable for the

respective task.

 Proceed in a very cautions and calm manner.

 Avoid endangering yourself.

 Switch the power off.

 Request medical help (emergency physician).

 Call for first aid if necessary.

2.3 Environmentally-Friendly Disposal

Manufacturers of B2B equipment are obliged to take back and

dispose of old equipment that was manufactured after 13 August

2005. As a principle, this old equipment may not be delivered to

communal collecting points. It may only be organised, used and

disposed of by the manufacturer. Valentin products accordingly

labelled can therefore be returned to Carl Valentin GmbH.

This way, you can be sure your old equipment will be disposed of

correctly.

Carl Valentin GmbH thereby fulfils all obligations regarding timely

disposal of old equipment and facilitates the smooth reselling of these

products. Please understand that we can only take back equipment

that is sent free of carriage charges.

The electronics board of the printing system is equipped with a

battery. This must only be discarded in battery collection containers or

by public waste management authorities.

Further information on the WEEE directive is available on our website

www.carl-valentin.de.

3 General Notes

3.1 Continuous Mode

Please note that the material has sufficient adhesion at the pressure

transducer roll or encoder roll to permit the exact speed by the

encoder.

It is only possible to print when respecting the operating conditions,

i.e. the speed has to be observed.

Figure 1

After starting a print order the printhead moves against the print

medium. The feed of material is registered by the encoder and then

evaluated. The printhead is in start position as long as the printing

onto the moving material is finished and then it moves back to its

home position.

Figure 2

NOTICE!

In case the encoder is connected to the counter-pressure roll

or the encoder roll you have to observe that the material has

sufficient adhesion at the pressure roll or encoder roll to

guarantee an exact speed by the encoder.

Figure 3

After starting a print order the printhead moves against the print

medium. Afterwards the printing carriage moves corresponding to the

set or transferred layout length linear over the material which is to be

printed. After the print procedure the printhead again lifts up and the

printing carriage moves again to the starting position.

NOTICE!

The direct print module is delivered with a default print length

of 65 mm. In order to use the maximum print length of 75 mm,

the print position value must be changed to 93.
