The LOGIJET T8-3 is a multifunctional non-impact printer based on
thermal print technology.
The device can be used for thermal transfer printing as well as for
thermal direct printing. Because of its wide range of application, you
can use it to print all kind of information as barcodes, alphanumerical
characters and vector graphics e.g. .
This printer not only knows one device-specific page description
language as standard thermal printers usually do, but most of the
languages used in the industrial field and the well-known market
standards of laserprinters, too.
For this printer options are available (for example, cutter).
The LOGIJET T8-3 printer is provided with a controller that is also
used in SOLID laserprinters. So the advantages of the thermal print
technology are combined with the flexibility of the „laserprinter intelligence“.
The MICROPLEX printer controller has its integrated website, this
allows a printer configuration via Ethernet. See Networking
Features of MICROPLEX Printers for more information.
Data can be sent without programming expenditure from almost
any software platform, because printer drivers are already
available for this.
The capabilities featured include the MICROPLEX page description
language IDOL. Using this language, complex tasks such as the
creation of forms can be carried out by simple software commands
(see separate IDOL manual).
The resolution is 300 dots per inch corresponding to about 12 dots
per mm.
The print speed is up to 6 inch/second (up to 150mm/second).
Roll-fed media as well as continuous-media can be printed on.
The maximum processable width of media for the LOGIJET T8-3 is
241.3mm (9.5”). 219.5mm (8.64”) of that are printable.
The thermal print technology enables a quiet and fast print process with a
high resolution output. The printhead produces the image by heating
single elements (dots). So you need a special ribbon (thermal transfer
printing) or a special kind of paper (thermal direct printing).
While thermal transfer printing the dots touch the thermal ribbon so that
the heating of particular dots leads to a partial melting of the ribbon. Due
to the contact with a media (future carrier of the information, for example
paper) this leads to a transfer of the image onto the media.
While thermal direct printing the dots touch the thermal paper directly.
The dyes and developers within the paper respond to the heat of
particular dots, change their colour to black and so the wanted image
emerges.
The printer LOGIJET T8-3 can be used for both methods of printing.

An output of the current setting values can be generated using the
"Printing the Status Sheet“ panel function (see section 6.9).
Detailed information on the operations above and to further
functions of the printer LOGIJET T8-3 can be found in the
following chapters.
Pay attention to the following safety instructions and the instructions
listed in section 1.5, too!
Safety instructions:
- The cutter (optional device of your printer) can cause injuries if the
printer is operated incorrectly.
- There is a danger of fingers, hair, clothing, jewellery etc. being
drawn into the machine in the vicinity of the material transport unit.
- Be careful when operating equipment with opened cover hoods
(setting-up work or service). Rotating parts can cause injury, and it
is possible for hair, clothing, jewellery, etc. to be caught in the
machinery.
- Print material should only be inserted and changed by specially
instructed personnel.
For thermal direct printing it is not allowed to load a ribbon to avoid
damaging the printhead. Make sure your settings using the control
panel and display respectively via interface (see chapter 5 and 6) fit
to the printer implementation (ribbon inserted /not inserted).
Ribbon and material should only be inserted/exchanged by specially
instructed personnel.
Fig. 4.1.a Winding directions of material and ribbon (here: ink outside the roll)
The diagram above shows the usual winding directions of material and
ribbon.
Pay attention to the different ribbon roll winding directions described in
section 4.2.1 Ribbon Loading. The figure above shows the winding
directions for “Ink outside the roll” ribbons. Also pay attention to the
instructions located on the inside of the printer hood.
Make sure you always use a printer ribbon being wider than the
media to print on. In the case of printing on abrasive media
printhead damaging can be avoided this way.
Fig. 4.2.1.k Tautening the ribbon by winding the ribbon rewind spindle
12. Check that the ribbon has no folds and is running straight.
If necessary, tauten the ribbon a little bit more by further
winding of the ribbon rewind spindle. Finally the ribbon has
to be firmly attached to the ribbon sleeve.
13. Swivel the printhead mechanism back to its original position
using both hands and making sure it clicks into place (force
is needed).
The unused ribbon can remain within the device until it is
used for the next thermal transfer operation (if necessary
protect the ribbon against unintentional unwinding).
The ribbon has to be loaded as described in section
The following steps are necessary if you want to switch from
printing in the thermal transfer mode to printing in the thermal
direct mode. In case only a used-up ribbon has to be removed
the steps 5 and 6 have to be omitted.
1. Switch the printer to OFF LINE mode.
2. Open the the printer hood completely.
3. Push the printhead release lever clockwise to open the print
head mechanism.
4. The core of a used-up ribbon can be removed by pulling it
from the ribbon supply spindle.
5. If the inserted ribbon is not used-up, cut it close to the
ribbon rewind spindle.
6. Rotate the ribbon supply spindle until the free end of the
ribbon is winded up.
7. Rotate the rewind spindle until the free end of the used-up
ribbon is winded up.
8. Remove the used-up ribbon from the rewind spindle and
dispose it according to the rules.
The media for thermal direct printing has to be loaded as
described in section 4.3.1.
The tear off roll-fed media is easier to insert if the end is gored
before inserting as shown in the figure below (when using a
new roll you should first remove the protection foil if necessary
and discard one full turn of the media).
9. Push the printhead release lever clockwise to open the print
head mechanism (compare figure 4.2.1.a, too).
Fig. 4.3.1.j Pushing the printhead release lever
10. Slide the material guide to its outermost position (maximum
throughput width).
Fig. 4.3.1.k Adjusting the material guide to the maximum throughput width
11. Feed the label material through the printer and out of the
printer passing the media sensor (therefore you have to
feed the label material through the “fork” of this sensor).
Compare figure 2.4.e to locate this part of the printer.
- Printing should always be carried out with the lightest contact
pressure possible for creating a satisfactory print quality. This
protects the printhead and the entire device.
- Excessive contact pressure can result in premature wearing of
the printhead.
In the factory this printer is set to the optimum values for the
standard printing application. The printout quality and the
occurrence of ribbon wrinkles, however, depend on a large
number of factors.
In particular the current material width and/or material thickness
have an large effect on the contact pressure of the thermal
printhead on the media and the platen roller.
To allow a compensation of such influences, the contact pressure
of the printhead is adjustable by 4 adjustment knobs.
The 4 green adjustment knobs are located above the printhead:
Fig. 4.4.a Printhead contact pressure: Position of the 4 adjustment knobs
A) Printhead pressure adjusting in a ballanced way:
1. Open the printer hood completely.
2. Push the printhead release lever clockwise to open the print
head mechanism.
3. If you want a better accessibility to the 4 green adjustment
knobs you can temporarily remove the ribbon first (compare
section 4.2.2 Ribbon Removal).
4. Please adjust the printhead pressure in the desired direction
by adjusting all 4 adjustment knobs in the same way.
Using the green adjustment knobs 5 levels for the prindhead
pressure can be choosen; level 1 causes the lowest pressure.
Adjusting the knobs clockwise will increase the printhead
pressure.
5. Swivel the printhead mechanism back to its original
position using both hands and making sure it clicks into
place (force is needed).
6. Generate a test print.
7. Repeat step 2 to 6 until you are satisfied with the printout
If (only) one side of the media is printed with good printout quality
or ribbon wrinkles occur, you have the possibility to choose an
“asymmetrical setting” for the adjustment knobs. This
allows an corresponding optimization of the printhead pressure.
Please note: Before choosing such an “asymmetrical setting” you
should check the handling of all consumables first
(compare chapter 4). If, for example, one of the
ribbon rolls isn’t mounted centered this already might
be the cause of wrinkles.
If an “asymmetrical setting“ for the printhead is indeed
necessary, the adjustment knobs have to be divided into two
groups:
Fig. 4.4.b Printhead pressure: Dividing the Adjustment knobs in two groups
Adjust the printhead pressure in the desired manner by adjusting
either te right side adjustment knobs or the knobs of
the left side.
- Use the last test print to check the „direction“ of the wrinkle.
The wrinkle can happen from the lower left to the upper right
direction (error image „ ´ “; seen in the printer’s feed direction).
On the other hand the wrinkle can happen from the lower right
to the upper left direction (error image „ ` “).
- Error image „ ´ “ : First of all please reduce the printhead
pressure on the right side by adjusting the 2 adjustment knobs
of the right side both about one step counterclockwise.
If both adjustment knobs already show level „1“ (i.e. the lightest
contact pressure is already chosen) then please increase the
printhead pressure on the left side by adjusting the 2 adjustment
knobs of the left side both about one step clockwise.
- Error image „ ` “ : The descriptions from above shall also
apply by analogy – you only have to interchange the words
„right“ and „left“.
- Generate a test print.
- Repeat the steps described above until you reach a satisfactory
print quality.
This symbol shows the MENU key. This key is used to turn the
printer OFF LINE and ON LINE.
In addition to that this key can be used to clear an error message
in the display after the fault was fixed.
In the OFF LINE mode the paper is conveyed one format
length further after having activated the FEED key.
In the OFF LINE mode this key is used to start thecutter
(cutter = option).
These keys are used for working within the different levels of the
menu structure.
This structure and the panel functions are described in the
following.
You can use the control panel to change the printer configuration and
customize your printer to meet your specific needs.
In addition printer configuration via Ethernet is possible.
The MICROPLEX printer controller offers an integrated website, for
more information see Networking Features of MICROPLEX Printers.
Chapter 6 (Panel Functions) describes how to reach the particular
printer functions via the panel.
T e m p o r a r y changes in printer configuration are effective only as
long as the printer stays turned on. To select such changes temporarily,
the user must terminate the change of function by pressing the
key one single time.
P e r m a n e n t changes in printer configuration are active each time
the printer is turned on again. To select such changes permanently, the
user must terminate the change of function by pressing the
key two times.
An output of the current printer values can be generated using the
panel function Printing the Status Sheet (see section 6.9).
Please note:
User default settings remain in effect until you save new settings
or restore the factory defaults.
Settings you choose from your software application or printer
driver can also change or override the user default settings you
select from the touch panel.
After the printer was turned on (and as soon as the warm up phase
is finished) the printer goes into the ON LINE – Mode
Printer messages are displayed on the control panel display.
This symbol shows the MENU key. This key is used to turn the
printer OFF LINE
If the printer is turned OFF LINE with this key you get automatically
into the first menu level.
Now this message is displayed on the display.
In the interest of simplicity, in the following chapters only the most
important display messages are shown in the Panel display column.
This symbol shows the MENU key. You get automatically into
menu level 1, if the printer is turned OFF LINE with this key.
By pressing the key or the key you can
move within the menu levels.
Each menu item/subitem within a menu level is shown in the
display.
The key has two main functions. It gives the user
access to a particular menu and, once in the menu, it allows the
user to select a particular function.
Pressing the key the displayed function value is confirmed
respectively the displayed function is activated.
The changes are saved temporay. (This means, the changes are saved
only until the next printer power off).
After this you have to decide, if you want to save the changes
permanent (Save as setup).
To select such changes permanently, the user must press the
key one more time. These permanent changes in printer
configuration are active each time the printer is turned on again.
If the key is pressed instead, the changes are only stored
temporary (not saved as setup).
(This key takes the user to the respective previous menu level).
Pressing the key takes the user back to the respective
menu level above.
Pressing the key switches the user directly to
ON LINE from any menu position. For this you have to press the
key longer than 2 seconds.
The Gap Sensor (Transparent Photoelectric Switch) is suitable for labels
with transparent or register gaps (Menu sub-point Punched). The Reflex Sensor (Reflex Photoelectric Switch) is suitable for materials with markings / Black
Marks (Menu sub-point Reflex).

The panel functions Sensor Test and Sync Sens Level serve to adjust the
Sync sensors specifically for the label material in use.
The following sections describe the steps to adjust the Black mark sensor
(reflex sensor) and the Gap sensors (transparent sensor) in form of flow charts
as well as in form of step by step listings.
6.1.4. Manual Adjusting of Sensor Current and Switching Threshold
*) Special solution: If the adjusting of the Gap Sync sensor failes because the contrast
value of the label material itself is very low, you can use the panel function
Sync.Sens.Logicto invert the logic. (Black marks can be used as “inverse gaps”

Use the and keys to set the CV value. Approx. CV value:
Load paper into the sensor.
The sensor measured value (VV level) of the paper (not black mark)
should count less than 10%.
If the VV level is too high, increase CV (sensor current).
Put a black markinto the sensor area.
The sensor measured value (VV level) of the black mark should count as
possible more than 45%.
If the sensor measured value (VV level)of blackmark is too
low, the CV value should be decreased.
Higher black mark VVvalues than 45 % are more advantageous so
long as there is no rising above 10 % of the paper VV level.
Measure both sensor levels once again for Paper and Black mark.
(You need the two level values of your material for the following switching threshold adjustment)

At the right the switching threshold value is displayed.
Use the and keys to set the
switching threshold of the sensor to the
middle between the paper level and the
black mark level:
Graphical explanation for switching threshold setting:
After selecting the panel function Sync.Sens.Level the contrast of
the inserted material (placed in the photoelectric sensor area) is shown
on the printer display. The left level value is the currently measured sensor value(You’ll find more details in the previous
sections.)
For all different contrast zones of the current material sensor values
(level values in %) have to be measured now. Place the material in the
photoelectric sensor area and read the level values.
Example:Self-adhesive material with black bars across the label
Zone of the inserted material: Sensor measuredvalue (level):
Label + liner + black bar 75 %
Label + liner 44 %
Liner (other names: carrier or backing)12 %
Calculation of the Switching Threshold
The middle between the label level (incl. liner) and liner level has to
be calculated:
(44% - 12%)/2 + 12% = 28%
In this example the switching threshold is to be set to the value 28 %.
(The steps to set the Sync sensor level at the printer panel can be found
on the following page.)
Graphical explanation for switching threshold setting:
This function allows to select the print process.
While thermal direct printing the device operates without ribbon,
direct thermal media is required.
While thermal transfer printing a ribbon is needed to transfer the
print contents onto the media (see chapter 4 Handling of
Consumables, too).
For thermal direct printing it is not allowed to insert a ribbon to
avoid damaging the printhead.
Make sure your settings match to the printer implementation (ribbon
inserted/not inserted).
6.6.1. Starting the (Printer’s) Measurement of Label Length
Use the panel function
Paper Menu \ Paper Size \ Page Length \ Measure Length
The printer performs a material feed and reports the measured label length on
the display.
Use the key to confirm this value (configuration of the measured
label length).
In addition this new value can be saved permanent as setup value (using the
key, again).
6.6.2. Configuration of Semiautomatic Label Length Measurement
The panel function
Paper Menu \ Paper Size \ Page Length \ Auto.Measurement
serves to switch the semiautomatic label length measurement function to on or
off (and to save this setting as setup value).
If the semiautomatic label length measurement function is chosen, the printer
automatically offers you the measurement of the label length after
every printer power on and after everyclosing of the printhead (for
example after the inserting of a new label roll):
Panel display [Measure length ]
Use the key to start the measurement of label length, use the
key to suppress this function.
The printer saves the measured label length temporal (as long as the printer
stays turned on).
This function generates a status sheet. The status sheet contains
information about the current printer configuration, the
available fonts and options.
The first lines, entitled SERVICE INFORMATION, contain
hexadecimal coded configuration parameters.
