Loading Software If Flash Contains Only Boot Code
267
IMPORTANT Do not interrupt the downloading process once it has started.
Interrupting a download will leave the flash memory on the controller
PCBA incompletely loaded, and the printer may not boot up.
While the file is copied into memory, the printer LCD informs you of the
load process and status.
16. When the new software has successfully loaded into flash memory and
the printer has reset itself, set the printer power switch to O (Off).
17. Remove the CD-ROM from the host computer and store it with the printer.
18. If required, reconnect the data input cable(s) to the printer.
19. Set the printer power switch to | (On).
20. Using the configuration printout(s) you made in step 1 on page 265,
restore the printer configurations. (Refer to the printer
User’s Manual .)
Loading Software If Flash Contains Only Boot Code
If the flash memory contains only boot code (e.g., if it is new), or if a download
was interrupted (e.g., by a power outage), you must download software
through the printer’s parallel port using the three-key initialization sequence
covered in this section.
1. Make sure the printer’s parallel port is available. In some configurations,
you may have to re-install the Centronics
®
I/O cable and connector in
order to load basic software into the printer.
2. Set the printer power switch to O (Off).
3. Disconnect the data (signal) cable(s) from the printer interface
connectors.
4. Connect a parallel data printer cable to the LPT1 port or LPT2 port of an
IBM-compatible computer running the Windows (95, 98, Me, NT, 2000, or
XP) operating system.
5. Connect the data cable to the Centronics port of the printer.
6. On the printer control panel, press and hold down the , ↓, and ↵ keys.
Without releasing the keys, power the printer on. When you see “B20:
STATUS 00% / DOWNLOAD MODE” on the LCD, release the keys.
7. Using Windows Explorer, create a directory named download at the root
level of your C: hard drive. (C:\download)
8. Insert the printer emulation software CD-ROM into your computer’s CD-
ROM drive.
9. Open the readme.txt file on the CD-ROM. There are two emulation sets
with corresponding part number files from which to choose:
CT / IPDS / IGP / ZGL / TGL / IGL / STGL
TN / IGP / ZGL / TGL / IGL / STGL
Both emulations include the LP+ emulation. They are offered in two file
formats: .exe and .prg. Use .exe files to download through the parallel
port.
10. Identify which emulation set you want to load into the printer and note the
filename that corresponds to that emulation. The filename is a six digit
.
