Appendix C: Downloading Printer Firmware
C–1
Firmware Update Procedure
The following instructions explain how to download updated printer firmware.
STEP 1. Power up your printer normally and print out a Configuration Report. This will give you a
hard copy of the printer setup. You will need this to restore any parameters that you have set
in the printer. Power the T6090 down.
STEP 2. Connect your printer to your computer using the parallel interface.
STEP 3. Power up the printer while holding down the following four keys on the control panel: VIEW
Key, LINE FEED Key,
▼
Key, and MODE Key. Hold them down until the following
message scrolls on the control panel display: “Mannesmann Tally Flash Loader.” The display
then stops scrolling and says: “Flash Dnld Ready.”
STEP 4. Change the directory to the floppy drive. From the DOS Command Prompt enter:
<filename> -P
This will cause the compressed file to expand directly to the PRN device.
The time required to update the firmware depends upon the speed of the computer you are
using. Typically the times will vary from 3—10 minutes.
STEP 5. After the download is complete, check the hard copy of the configuration and set up the
appropriate parameters.
The firmware download is now complete.
You will get an NVRAM fault at the end of the download. It does not indicate a problem
with the printer, simply depress the CLEAR Key on the printer control panel and the
message will clear. You will need to perform a print calibration, paper motion sensor
calibration , and a paper out sensor calibration. (These calibraiton routines are ex-
plained in Chapter 2, under PrntCal, Pap Mot, and Pap Out parameters, respectively.)
The printer is now ready for use.
