ADJUSTING PARAMETERS
77144 Issue 8 August 2009 123
In the sample below the speed parameter is set too fast, causing the message to
become squashed and unreadable.
Note: It is important to keep the speed setting on the control unit relative to the
conveyor speed. If not, this can lead to distortion of the messages and
inaccuracies with other parameters like dpi and delay. The maximum line speed
is 144 metres per minute (depending on dpi), conveyors of higher speeds are not
recommended.
Dots per inch (dpi) is the resolution that the message is printed, the higher
the resolution the more dots are packed into an area creating a tighter, sharper and
higher quality print out. The printer controls the output resolution by adjusting
the horizontal scale of the print out - a message printed at 300dpi will be smaller
than the same message printed at 75dpi.
The default output resolution is 200dpi. The resolution ranges from 75 to 300dpi.
The higher end of the scale is generally intended for graphics (“logos”) and high
quality text. The lower resolutions are intended for less quality dependant and
faster jobs. When the speed parameter is set correctly, the DPI value will print out
correctly. As the dpi increases, the maximum print speed will go down.
Note: If the DPI is set above the recommended value for the current speed, the printer
will change the speed value accordingly.
(1) The screen sample shows which screen
prompt appears when the DPI icon is
pressed. If the dpi has not been changed, the
current dpi setting should read 200. Beneath
the current settings is a list of available dpi
settings. On the last line there is a flashing
cursor block, where the new value should be
entered. Press enter to confirm the new
resolution.
CURRENT DPI = 200
ACCEPTABLE VALUES
ARE 300 240 200 170
150 120 100 75
ENTER NEW VALUE
In this screen sample the
resolution is set at default
200dpi and shows the range
of alternative resolutions
available.
