Pressing RIBBON ECONOM again, the selection stops and a test label is printed where
the width of the central zone (black, grey and bars) it adjust to the value given to the
margins always keeping itself centered with respects to the printhead. The adjustment of
margins is of help to avoid any possible ink stains on the rubber roll in case of using
narrower labels compared to the previous label width. In case of using different label
formats it is useful to leave the printer set with margins corresponding to the narrower
one sending time by time from line the correct command on the basis to the text to be
printed. At this point exit from configuration mode (as described in paragraph 13.8) in
order to execute the modifications programmed.
13.12 PRINTING SPEED SELECTION

fine adjustment, respectively to up and down of 10mW each time.
Each key pression a test label is printed that shows the variation.
It is always advisable to operate at the minimum speed in case of rough
temperature adjustments to avoid any possible burns of the ribbon during the
passage of values. Now exit to the configuration mode (as described in paragraph
13.8) in order to execute the modifications programmed.
13.14 LABEL CALIBRATION
Select the printer in configuration mode (as described in paragraph 13.8) then
press the FEED key. Two white labels are ejected and
than a test label is printed containing all the values of
parameters P and H updated referring to the kind and
length of the label correctly mounted on the printer.
Value P is proportional to the transparency of the used
material, measured before feeding paper : it is important that in case of pre-printed
labels the paper is initially positioned in the way that under the sensor is present a
light zone and that the sensor is not reading on the gap between labels. Valid
values of P are from 52 to 255 (normally from 60 to 120), whilst extreme values of
51 or 256 indicate generally a malfunctioning, due to the absence or excess of
sensored light. Values near or exceeding 200 indicate a wrong starting position of
the paper (reading on the gap between the labels) or the use of materials very
transparent that can constitute a problem for a correct step maintaining.
The value H represents the feed paper (in dots) made from when the edge of the
label has been detected by the sensor, to correctly align the label under the printhead: these value changes relating to the height of the labels in use. The printer
calculates automatically with a certain approximation (generally less) the value
adapt to start printing from the upper edge of the label.
In case the FEED key is kept pressed, after ejecting the two white labels and
before the test print-out, the paper is fed slowly, increasing the value of H and,
therefore, lowering the starting point with respect of the edge till the key is left. This
is useful to make a fine adjustment and to find the correct label stop position to
allow the easy detachment in case of dispensing mode (with silicon paper
rewinding). In case of use of different label formats with frequent passage from one
to the other it is not easy to make a new adjustment at each label format: it is
advisable in this case to take note of P and H value reached initially for each used

14 MAINTENANCE
Due to the reduced number of moving parts, the printer does not require particular
maintenance, but a simpler periodical cleaning of the parts subject to dirt, that are:
• printhead
• feeding rubber roll
• paper guide shaft
• label presence and label gap photosensors
It is advisable to fulfil the maintenance operations weekly in case of intense use of
the printer, monthly in case of irregular use.
A paint-brush or an air jet is enough to remove the dust due to the labels sliding;
pay particular attention to the photosensor holes.
As far as the printhead, rubber roll and paper guide rolls are concerned it is
advisable to use iso-propylic alcohol and a soft cloth.
WARNING: Never use any metallic or hard tool to clean the
printhead as indicated on picture 35.

WARNING: Switch off the printer handling on the button
mounted on the rear panel of the printer and disconnect the
spindle from the feeding plug.
As previously explained in paragraph 8, please proceed with the following operation
by keeping the printer with:
• Cover open
• Lifted printhead
• Remove the cartridge and paper not installed
The operator will then be free to execute the following operation:
14.1 PRINTHEAD CLEANING
Take a cotton swab wet with isopropylic alcohol and pass it
under the printhead to eliminate
all the carbon residuals due to
printout, as indicated in picture
36 on your left. Note that the
printing quality also depends on
a good printhead cleaning.

14.2 RUBBER ROLLS CLEANING
Take a soft cloth wet with isopropylic alcohol and pass it over
the rubber rolls to eliminate all
the dirt (silicon residuals and
possible inked ribbon residuals)
posed during the labels printing
as indicated on picture 37 on your
left.
Picture 37
Remember that good printing
quality also depends on the good cleaning of rubber rolls cleaning as they are mechanical
parts dedicated to the paper movement.
14.3 PAPER GUIDES METALLIC SHAFTS CLEANING
The cleaning of the shafts is made to
eliminate glue residue from the selfadhesive labels during the printing
process.
It is important to keep them clear as
the glues on the labels create a sticky
layer causing the paper to brake.
Keep a soft cloth wetted with isopropylic alcohol and pass it on the
shafts and on the inox metal strip located after the roll holder being care-ful
to clear all the glue traces from the
above-mentioned parts, as indicated in
picture 38 on your left.
When the maintenance operations are
over, re-install the labels and the cartridge (following the instructions described in the relative paragraphs),
close the covers and switch the
printer ON.
