0150 Backup memory read/write
error (main/engine PWB)
No response is issued from
the device in reading/writing
for 5 ms or more and this
problem is repeated 5 times
successively.
Mismatch of reading data from
2 locations occurs 8 times
successively.
Mismatch between writing
data and reading data occurs
8 times successively.
0160 Backup memory data error
(main/engine PWB)
Reading data from EEPROM
is abnormal.
0170 Billing counting error
The values on the main circuit
PWB and on the engine do
not match for any of charging
counter, life counter, and
scanner counter.
0180 Machine number mismatch
Machine number of main/
engine does not match.
0190 Backup memory device
error (main/engine PWB)
0630 DMA error
DMA transmission of image
data does not complete within
the specified period of time.

Check procedures/
corrective measures
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Check that the EEPROM is peroperly
installed on the main/engine PWB and
re-install it.
3. Replace the main/engine PWB (see
page 2-2-11).
4. Check the EEPROM and if the data are
currupted, contact the service support.
1. Turn the main power swtch off and after
5 seconds, then turn power on.
2. Execute U021 - memory initializing.(see
page 1-3-19)
3. If the EEPROM data are currupted,
contact the service support.
1. Check that the EEPROMs installed in
the main/engine PWB are correct and, if
not, use the correct EEPROM for the
model.
2. If the EEPROM data are currupted,
contact the service support.
1. Confirm the machine data for the main/
engine units by using U004 (see page 1-
3-17).
2. If the serial number data of different
models is alternately displayed, install
the correct EEPROM in the PWB of the
wrong serial number data.
3. Contact the Service Support.
1. Confirm that the wiring connector is
firmly connected and, if necessary,
connect the connector all the way in.
2. If the wiring is disconnected, shorted or
grounded, replace the wiring.
3. Replace the main/engine PWB (see
page 2-2-11).
