5.6 Darkness Adjustment
The Darkness Adjustment (located on the rear of the printer) allows the
operator to match the print contrast following a printhead replacement.
Turning the Darkness Adjustment clockwise will darken the print, while
turning it counterclockwise will lighten the print. Compare a label printed
with the old printhead and make this adjustment so that the new printhead
matches the darkest portion of that label.
; Note: Large increases in the ‘Darkness Adjustment’ can shorten printhead life.
If you need to increase the darkness of the printed labels, increase the
Heat value and/or slow the Print Speed using your software program or
via DPL commands.
5.7 Resetting to the Factory Defaults
With the printer power ‘Off,’ press and hold the F1, F2, and F3 buttons
while turning ‘On’ the printer. Continue to hold the buttons down until
the PAUSED Light turns off. The printer will now be set to the ‘Factory
Defaults.’ See Section 4.4.1 for a listing of the factory default settings.
5.8 Downloading Firmware and Fonts
The operating programs and fonts for the printer are stored in Flash
memory on the Main PCB. When program updates and/or new features
are added, they can be downloaded to the printer as follows:
1. Identify the new version for your model of printer from the Datamax
FTP site at ftp://ftp.datamaxcorp.com and download it onto your
computer’s hard drive or a floppy disk.
2. Ensure that the printer is connected to the host and that the power is
‘On.’ Using the DOS copy command enter:
copy filename.dlf lpt1/b
; Note: Other programs (e.g., hyper-terminal and certain Windows
Driver programs) may also be used to download this file.
