OF2.6
* Circles Continuously.
PROCEDURE
When the * is circling continuously, it is not
receiving messages from the ESS PWB.
Perform the following checks. Retry between
each check.
1. Remove and reseat the ESS PWB. (you
may want to remove the left side cover
and the EME shield to ensure that the
PWB is seated.
2. Disconnect the NIC, if one is present.
3. Remove and reseat the DRAM SIMM’s on
the ESS.
(C55/C55mp)
If there are more than two
SIMM’s check to ensure that the larger
value SIMM’s are installed in J8 and J9
4.
(C55/C55mp)
Check the version of the
ESS PWB. The number is written in
yellow ink, parallel to the ESS face plate
near the bottom of the ESS. The bottom
of the ESS is the point FURTHEST away
from the DRAM SIMM’s. If the ESS PWB
number is
160K43690 or 160K49680
Replace the ESS PWB.
5.
(C55/C55mp)
Reconfigure the ESS PWB
to the original RAM configuration (2-8 MB
SIMM’s) this will verify if this is a DRAM
problem. If the printer works in the original
configuration but not with customers
memory, replace the ESS PWB.
6.
(C55/C55mp)
If the ESS IF PWB (PL 3.1
#6, 160K32850) has been replaced, check
to see that it has a plastic insulating
washer at each mounting hole. Some of
the spare 160K32850 were manufactured
without these washers. (A purge is under
way to fix this problem. In the meantime,
contact your Technical Support
Organization)
7. Check CN104 harness (between PCU
PWB and IF PWB).
8. Replace PCU PWB.
9. Replace ESS IF PWB (160K32850).
OF2.7 Rebooting message never clears.
When the Rebooting message is displayed the
ESS is booting and waiting for a ready
message from the IOT. The rebooting
message usually lasts for approximately
1 minute and is followed by the Initializing
message.
PROCEDURE
Switch the power off wait 10 seconds and
switch the power on and recheck for the fault.
1. Switch the power off and unplug the ESS
by sliding it out about 6 inches.
2. Run the IOT Test Print.
a. Hold
Menu [3]
and
Enter [7]
and
switch the power on.
b. User
Menu [3]
to scroll to Test Print.
c. Press
Form Feed [1]
.
4. If you cannot enter diagnostics or the test
print does not run, replace the PCU PWB.
5. If the Test Print is produced, replace the
ESS PWB.
