When necessary, the exterior surface can be cleaned using a general
purpose cleanser and a soft cloth or sponge. Clean printers exterior
covers as follows:
Turn ‘Off’ and unplug the printer.
Gently wipe the exterior surfaces until clean and then allow time to
dry.
Plug in and turn ‘On’ the printer.
CAUTION

cleansers into the printer or allow over-spray to get on internal
components, such as the printhead. Damage can result.
4.4.7 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 Web
site at www.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, (via parallel port only) and
that the power is ‘On.’ Using the DOS copy command enter:
copy filename.dlf lpt1/b
(non-display printer firmware is .dlf extension)
copy filename.zs lpt1/b
(display printer firmware is .zs extension)
Note: Other programs (e.g., hyper-terminal and certain Windows
®
Driver programs) may also be used to download this file.
3. The ON-LINE light will flash during the download.
