26.11 Memory Card
Adapter Troubles
• The memory cards used must comply with the JEIDA-4 stan-
dard. PCMCIA-cards may not work properly.
• In case of non Dos-formatted memory cards, check that the
write protect switch on the memory card is enabled. If so, try
another similar memory card.
• In case of the printer not using a startup (autoexec) fi le on
memory card, check that there are no other startup fi les in other
parts of the printers memory, that have higher priority.
The printer uses startup fi les in the following priority order:
1. Dos-formatted memory cards (SRAM).
2. Printer's internal RAM memory.
3. Non DOS-formatted memory cards (SRAM or OTPROM).
4. Printer’s ROM memory, that is, confi guration EPROMs.
• If you have access to a PC equipped with a card reader, list the
memory content of the PC memory card to see if it is correct.
In case of a SRAM card, the information stored may have got
lost due to some malfunction in the card’s battery backup or an
empty battery.
• If you can communicate with the printer via a PC, you could
see what fi les are stored in the memory card and the size of
them with the aid of the Fingerprint instructions FILES "rom:"
(non DOS-formatted cards), or FILES "card1:" (DOS-format-
ted cards). In case of non DOS-formatted cards, compare with
the content of the printer’s ROM memory, when no card is
inserted.
• If the memory card and the software appears to be OK, go on
and check the hardware:
• Check that the memory card adapter is connected to the CPU
board via a Bus Driver board, see Chapter 13.1. Occasional
errors, such as “1041 Error in FOS structure” and “5 Unrec-
ognized Token”, have been reported for memory card adapters
without a Bus Driver board.
• Check that the Bus Driver board is centered in the memory
expansion connector P-1 on the CPU board.
• Pull out and push back the card a few times to see if it was not
poor contact, for example oxidation, between card and adapter.
Note! The printer must be switched off.
• Inspect the memory card for mechanical damages. Examine the
memory card adapter pcb for breakages or bad soldering.
• Check that the GAL package on the memory card adapter is a
20V8 and that it is mounted correctly.
