2. GETTING STARTED, cont'd.
9. Bypassing a Startup
Program
The following methods are only recommended as a last resort,
when there is no other way of breaking a startup program.
By default, there is no facility for breaking a startup file in a printer
without a keyboard. Although a break interrupt can be issued from
the host, this option is disabled by default. Thus, the startup file
should always be provided with some facility for issuing a break
interrupt from the host. Refer to the instructions for the program in
question.
If such a facility still is missing, or you do not have the required
information, you may use the Test Mode to bypass the startup
program, provided your printer is fitted with a keyboard:
• Turn off the printer.
• Lift the printhead.
• Press the <Print> key and keep pressing it while you turn on the
power. Do not release the <Print> key yet.
• After half a minute or less, the printer will enter the Test Mode,
which is indicated by this message:
TESTMODE:
TESTPRINT
• Now you can release the <Print> key. The Test Mode is primarily
intended for factory and service tests (see the Service Manual),
but it also contains another facility which is very convenient in
this situation.
• Press the <Setup> or <Save> key. A new message is displayed:
Fingerprint
6.13
The printer has now entered Fingerprint's immediate mode, ignor-
ing the startup file. The communication parameters have been reset
to their default values and the standard IN/OUT channel has been
set to "uart1:".
Note that this does only apply until you restart the printer without
entering the Test Mode. Then the startup file with its original setup
and choice of communication channel will become effective again.
However, after entering Fingerprint via the Test Mode you can
KILL the startup program and – if so desired – recreate it later, see
chapter 5.13 “Creating a Startup Program”.
Proceed at chapter 2.10.
If nothing else works, you may need to
remove the configuration EPROM's or
memory card containing the startup
program.
Furthermore, if the startup program
resides in the RAM memory, you may be
forced to erase the entire RAM memory
by removing all RAM packages from the
CPU-board, wait for a few minutes and
then reinstall the RAM packages. Finally
restart the printer. Note that this may
cause valuable data to be lost!
