IPR-C1 error code E00820-003....

[mark921]

error code is saying error in transfer unit cooling fan, however, the 003 part is not listed in my service manual.

Visual inspection confirms the fan is not powering up, and there is an absence of 24V.

Re-seated all of the connections in the DC controller...no change.

Replaced the DC controller...no change.

Checked the wiring harness leading up to the fan, and seems well.

Just for grins, replaced the cooling fan...no change.

any thoughts? as always, thank you in advance for any input...

Problem :
The imagePRESS C1 displays an E820-0003 at power ON. What is this subcode referring to?

Solution :
The E820-0003 error code with this subcode refers to FM7 ITB Cleaning Cooling Fan. This fan provides cooling of delivered paper. The fan connects to the Side Driver PCB at connector J3404 pins 4, 5 and 6.

You can also test the fan via the Parts Check in service mode at COPIER>FUNCTION>PART-CHK and set FAN to 7.

You are on the right track, but the DCON does not control the fan. The side driver PCB does.

Additional info:

Workaround :
When checking voltages to the fan, the fan should run at high speed when the copier is first turned on and 24 volts should be present on connector J259 pin 3 shown in the diagram below. When the fan slows down to low speed, 12 volts will be present on the same pin of connector J259. In this case, there was only 12 volts when the machine was turned on, and the fan ran at low speed all the time. Something was taken down the 24 volts. After removing 24 volt loads one at a time from the Side Driver Pcb, it was discovered that unplugging the Primary Corona Wire Cleaner Motor caused the 24 volts to return to the fan and the machine booted up normally. In this case the Primary Corona Wire Cleaning Motor was taking down the 24 volts. The Primary Corona Assembly was replaced, to resolve the issue.

I also have notes stating the primary carona assembly can ground out causing the 24v to drop so I would inspect it to make sure you are not having that issue.

Good luck!

And we have a winner!

Charm, it was indeed the side driver PCB. New one was installed, and it took right off!!

Thanks again for the expertise!!! Very much appreciated!!
