Control Codes
Some errors cannot be reported to the host system. These errors are such that the integrity of the printer does not
allow continued operation and has no way to report the error. These errors (for the most part) occur during power
up diagnostics. They are as follows:
EEPROM READ ERROR
The Internal EEPROM is not readable or the check sum is bad. Pressing the * Button will attempt to rewrite the
configuration information. This may leave the printer configured incorrectly.
EEPROM WRITE ERROR
The Internal EEPROM is defective. There is no recovery.
SOFTWARE ERROR VECTOR
These errors can occur during operation. They signal a serious problem with the system. In most cases this error
will also generate a Watch Dog reset. A power cycle will generally recover normal printer operation. An ESD
event or a firmware bug generally causes these errors. The printer maintains an error log, this log contains
additional information about the fault and is printed during manual configuration. The information in this log should
be reported to TransAct to identify the exact cause of the fault.
USERSTORE FORMAT ERROR
The User Store data in FLASH has an invalid format. Pressing the * Button will erase the user store and reformat it.
This can be caused by a firmware update.
ELECTRONIC JOURNAL FORMAT ERROR
The Electronic Journal data in the FLASH memory has an invalid format. Pressing the * Button will attempt to
recover the data and fix the format. If this process is not successful, the printer must be returned for service. The
electronic journal information may be lost. Removing the power from the printer while the flash memory is being
updated or before the journal entry is complete could cause this. If the jounal record is incomplete, the power up
recovery will be able to correct the format and only a small portion of the last journal record will be lost.
FLASH WRITE ERROR
The program flash has failed. There is no recovery from this error.
COM ADAPTER ERROR
The communications interface card is either not supported by the firmware, or is missing. It is possible that the
communications adapter is not installed correctly. If reinstalling the adapter I\does not correct this error, the printer
will have to be returned for service..
Programmer's Notes
When the serial port is used, it is important that the output lines from the printer not be shorted or back driven by the
host system. If the signals are not to be used, they should be left open. Pins 3, 4, and 7 (of the 9 pin connector) are
outputs from the printer. If any of these signals are grounded or back driven, the other outputs will be degraded.
