E240 Error Code, Control Panel Locking Up, Power Suddenly Being Shut Down; E245/E246/E247 Error Code; E350 Error Code; E354 Error Code - Canon ImageRunner iR8500 Series Service Manual

Chapter 15
Inspect the primary charging ass'y for soil, contaminations, or abnormalities such as leakage at the block for the charging wire. Also, check whether
poor contact occurs between the ass'y and the host machine.
If there is no anomaly, check the connection of T601, J723 and J730 on the HV-DC transformer PCB. If there is no problem, replace the PCB with
a new one.

15.2.7.2 E240 Error Code, Control panel locking up, power suddenly being shut down

iR8500 / iR7200 / iR105 / iR85
Case in the field
Symptom

E240 Error Code, Control panel locking up, power suddenly being shut down

Explanation
E240: A communication error occurs between the main controller PCB and the CPU of the DC controller PCB.
Cause
1. There are several cases in the field that a faulty HDD caused this problem.
2. There is a case in our inspection that the main controller PCB was found to be faulty.
Field Remedy
1. Execute HD-CHECK and if the problem is not solved replace the HDD with a new one.
2. Check whether the connectors are securely fitted or the cables are not pinched between the main controller PCB and the DC controller PCB. If there is
no problem with them, replace the main controller PCB with a new one.

15.2.7.3 E245/E246/E247 Error Code

iR8500 / iR7200 / iR105 / iR85
[ Manual-related ]
Description
E245/E246/E247 are displayed when the counter memory PCB is faulty.
* E245/E245: After replacement of the counter memory PCB, the error will be automatically cleared and the soft counter data will taken over.
* E247: After replacement of the counter memory PCB, the error will be automatically cleared and the soft counter data will also be cleared.
Field Remedy
When E245/E246/E247 are displayed, replace the counter memory PCB with a new one. For procurement of the PCB, contact a division concerned.
If the error code does not disappear even after installation of the new PCB, put the original PCB back to the machine and contact the division.
**Things to be PROHIBITED**
Never install the PCBs listed below that have been taken out from other machines. In such a case, the error cannot be cleared. In some cases, the
serial number or the soft counter will be rewritten.
- Counter memory PCB
- Serial number PCB
- Main controller PCB

15.2.7.4 E350 Error Code

iR8500 / iR7200 / iR105 / iR85
[ Manual-related ]
Description
E350 is displayed when the serial number PCB is faulty.
* After replacement of the serial number PCB, the error will be automatically cleared and the soft counter data will be taken over.
Field Remedy
When E350 is displayed, check the connection between the main controller PCB and the serial number PCB. If there is no problem found, replace
the serial number PCB with a new one. For procurement of the PCB, contact a division concerned.
If the error code does not disappear even after installation of the new PCB, put the original PCB back to the machine and contact the division.
**Things to be PROHIBITED**
Never install the PCBs listed below that have been taken out from other machines. In such a case, the error cannot be cleared. In some cases, the
serial number or the soft counter will be rewritten.
- Counter memory PCB
- Serial number PCB
- Main controller PCB

15.2.7.5 E354 Error Code

iR8500 / iR7200 / iR105 / iR85
[ Manual-related ]
Description
E354 is displayed when a mismatch occurs in the serial number data.
* It occurs when installing the counter memory PCB, the serial number PCB and the main controller PCB that have been taken out from other
machines.
* Under the condition that the original serial number PCB are installed, when replacing the counter memory PCB with a new one and executing
'E355CLR', the error will be cleared and the soft counter data will also be cleared.
Field Remedy
1. If E354 is displayed as a result of installing the PCBs listed below that have been taken out from other machines, put the original PCBs back to
the machine and troubleshoot the problem before E354 indication.
2. If E354 is an error code that was first displayed, replace the counter memory PCB with a new one. For procurement of the PCB, contact a division
concerned. After replacement, execute 'E355CLR'.
