 Overview

The 8000+ Range Print Heads

The Jet•A•Mark 8000+ range comprises of the MINI, MIDI and MAXI print head
types. Each type has different printing characteristics with respect to print resolution
(drop size) where MINI print heads are used for high resolution printing and produce,
therefore, small drops, MAXI heads print at a low resolution using large drops and
MIDI heads have printing characteristics falling in the middle of the two.

8000+ MAXI 7v 8000+ MAXI 16v 8000+ MAXI 32v

Each print head type is available in three models: a 7 valve print head, a 16 valve
print head and a 32 valve print head, one for each maximum print height.
See “Print Head Comparison Charts” on page 17 for tables showing the differences
between the print heads.

OVERVIEW

Print Head Compatibility

The 8000+ print heads are fully compatible with control units used for 8000 print
heads. An 8000+ print head can be used to replace an existing 8000 print head that is
in operation. There is no need to make any changes in the control unit and its settings.

Pigmented Inks

Failure to correctly use pigmented inks, as described below, can cause

permanent damage and void the print head’s warranty.

All maintenance information contained in this manual is only applicable when using
non-pigmented inks.
If an 8000+ print head is to be used with pigmented inks a Matthews CISU
(Circulating ink Supply Unit) must also be used. The operation and maintenance
information provided in the CISU’s Operator manual must be adhered to.

 Installation
See also “Troubleshooting” on page 18.

Adapting to Print Direction

Each 8000+ range print head is equipped with a print target guide plate which is used
to partly prevent the newly printed dots being smudged by the print head itself and
partly to flatten uneven surfaces.
Using a size 10 torx driver, mount the guide plate according to the following:

The arrows show the direction in

which the print target shall pass
in front of the print head.

Positioning
Follow these guidelines when installing 8000+ range print heads.

• Position the print head so that it is as close as possible to the print target during
printout. The maximum print distance is 25mm (1in)1.
• The ink supply tube should be made as short as possible and no longer than 15m
(50ft).

• To avoid ink and cleaner fluid spill, ensure that all tubes (including connections and
joints) are mounted so that they can not be damaged or inadvertently detached.

• Please see “Print Head Comparison Charts” on page 17 for the maximum print
target speed.

• Make sure that the print head is not positioned so that the print target can knock
against it. It may be necessary to mount a guard rail so that the print target cannot
change its path.

Reconditioning and In-Service-Rotation of Print Heads

The following recommendations are provided to ensure correct operation of print
heads that have been inactive for six months.

Reconditioning a Print Head prior to Installation

If the stamp on the print head package indicates that it was produced more than six
months prior to the actual date, it is strongly recommended that the print head is
reconditioned before it is put in to operation.
Poor print quality, uneven ink drops during printout, and slight leakage from the
nozzles (weapage) can occur if print heads are not correctly prepared, as described
below.
Please follow the instructions below if a print head has been inactive for more than
six months.

Safety glasses and solvent resistant gloves must be used when contact with ink or
solvent liquids is possible. If cleaning solution comes in contact with skin wash it
immediately. If contact is made with eyes or mouth, wash them for at least 15 minutes
and seek medical advice.

The following procedure sets the printer up to print a message approximately seven
times a minute.
1. Connect cleaner fluid, from an ink-supply unit, to the print head’s ink-supply
line. See “External Parts” on page 3.
2. Set the ink pressure according to “Print Head Comparison Charts” on page 17
and turn the ink-supply-unit ON.
3. Use the print head’s external flush valve and flush the print head for about 5
seconds.
4. Connect the print head to a control unit.
5. If the print head has an internal three-way-valve set it to Ink. Use the control unit
to set it to Ink.
Note: The seven valve print heads and the sixteen valve basic do not have an

internal three-way-valve.
6. Create a message consisting of 10 characters. Select a font that will use all of the
print head’s nozzles.
7. Set the following parameters for the respective control units listed below.

8. Place an object in front of the photocell (printout activator) so that printout is

continuously activated.
9. Start printing and allow the print head to run for an hour. Once complete the
print head will be ready for delivery/installation.

In-Service-Rotation of Spare Print Heads

In installations where spare print heads are kept in stock, the spare heads should be
rotated in-service, every six months. This will ensure correct operation of the print
heads when put in service.

Print Heads 8000+ Range - Technical Manual - Version: 1 Issue: 1 11

I N S TA L L A T I O N

If spare print heads are rotated every six months, there will be no need to recondition
them, as described above. The spare heads will simply require flushing with cleaner
and ink before use, as described under “Starting Up” on page 14.
Before removing a print head from service its ink lines and nozzles must be flushed
with cleaner.

Connecting to an Ink Supply Unit

Safety glasses and solvent resistant gloves must be used when contact with ink or
solvent liquids is possible. If cleaning solution comes in contact with skin wash it
immediately. If contact is made with eyes or mouth, wash them for at least 15 minutes
and seek medical advice.

Note that the standard Matthews Swedot warranty is void if the 8000+ range print
heads are used together with any other than Jet-A-Mark ink supply units.
For procedures relating to a specific ink supply unit, please see the documentation
received with your unit.

General Information

• Use the Matthews 2x1 litre HP ink supply system or FPS (Basic or Advanced) for
ink delivery.

• All 8000+ range print heads are run in with the ink type specified by the customer.
Damage will occur and the warranty will be void if the head is used with any other
ink type. Please contact your dealer if you wish to change ink types.

• When flushing and cleaning, use only cleaner fluid which is suited to the ink type
being used.

• Please see “Print Head Comparison Charts” on page 17 for information on the
nominal ink pressure range for the applicable print head.

• Do not use pressurised (factory) air.

Ink Tube Recommendations

The choice of tubing, between the print head and ink supply unit, is dependant on the
type of installation according to the following:

Type of installation Choice of tubing Diameter: mm (inches)

Normal printing frequency and Standard Internal: 3,2 mm (0,125 in)

ink usage. External: 6,4 mm (0,25 in)

More than one print head High capacity Internal: 6,4 mm (0,25 in)
connected to a single ink supply External: 9,5 mm (0,375 in)
unit.
Continuous or barcode printing.

Ink Filtering Recommendations

Under normal printing situations the ink supply unit will take care of any ink filtering
needs and extra filtration is therefore not necessary. An exception is when 1700A ink
is being used. This ink requires that a standard (CS marked) filter is used between the
ink supply unit and the print head. Please contact your dealer to order the filter.
