The customer had a misfeed in this machine so I went out and took it out, but I believe the copier is overfeeding due to a dirty clutch. I know on the right side on the copier there are 6 screws to take out in order to get the paper feed section out so I can get to the clutches but when I took the screws out it just became loose and wouldn't come out. Is there something else I am missing that I need to take out out in order to get the paper feed section out? I am also getting an E065 error code. What causes this code, and what can I do to take care of it? Any help appreciated, thank you.

E065 is a problem with the Composite Power Supply, high voltage loss. Occasionally I've seen a bad transfer charge roller, but 10 times out of 11 it is the Composite Power Supply.
Are you sure that it's a misfeed problem, or more likely the machine just errors out with a E065 during copying? I have no recollections of removing the paper feed section (other than the fact that it was a pain in the ...). =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Yes I did see the copier misfeed a couple of times with the error code but it also misfed w/o the error code. I am thinking though it is related. Where is this circuit board located. I don't have a manual for this copier.
Thanks!!!Comment

It covers most of the back of the copier. The big one: FG5-7990-020 =^..^=If you'd like a serious answer to your request:

You have to remove the small cover to the right of the cassettes and then remove both lifter motors then the unit will come out. Blackcat is right 10 out of 11 its the composite.Comment

hi tcypy1961
blackcat 4866 is write about E065 if it spears once suspect the composite p.s.Comment

If your error code comes and goes> Also check the bias contact to the upper fuser roller make sure it is not shorting out or not making good contact with upper fuser roller. Must have good contact at both points.
+check your transfer roller > a short circuit while copying, will throw jam code ,followed by e065

Identifying an Error by LED
You can identify the following errors by referring to how and how long LED 101 on the DC control turns
ON (flashes).
OPERATIONS AND TIMING
ON for 0.5 set/OFF 0.5 for Normal
ON for 5 set/OFF for 5 = An error detected in comunication between composite
Power supply and DC controller
Harness (faulty) or Microprocessor (faulty)
ON for 2 set/OFF for 2 = Short circuit in low voltage
Harness (faulty)
DC load (faulty)
Microprocessor (faulty)
ON = Error
Composite power supply PCB LED drive circuit
(faulty)
Microprocessor (faulty)
OFF = Error
Composite power supply PCB LED drive circuit
(faulty)
LED connector (off, power contact; J114 on
DC controller PCB, J905 on composite power supply
Microprocessor (faulty)
Detecting Errors in the Composite Power Supply PCB
1. Outline
The NP6035 is equipped with a composite power supply, and a microprocessor (Q401) is located on
the composite power supply PCB.
The DC controller PCB and the composite power supply PCB exchange data over an E-bit data line
and a 3-bit command line. In addition, the NP6035 includes a P-bit communication check line, two serial
communications lines, serial communications lock signal line, and signal line for turning on LED101 on the
DC controller PCB.
/--\
If any of the following errors occur, the DC controller PCB uses the data from the error data transmission
line to indicate a self diagnosis code on the control panel or to turn on (flash) LED101 to communicate
the presence of an error.
Leakage of Transfer Bias
When the error detection circuit for transfer bias turns on and the TPRTCT signal is sent to the microprocessor
(Q401), the microprocessor (Q401) communicates an error to the DC controller PCB by
means of high-voltage error status data so that ‘E065’ will be indicated.
Communication Error between DC Controller PCB and Composite Power Supply PCB
If a communication error has occurred in the communication between DC controller PCB and composite
power supply PCB, the DC controller PCB indicates ‘E244’ on the control panel and, at the
same time, flashes LED101 on the DC controller PCB at intervals of 5 sec. When an error associated with ‘E244’ is detected, the DC controller turns off all outputs in 5 sec.
(LED101 on the DC controller PCB, however, will continue to flash.)
Short Circuit in the DC Power Supply Circuit
When the composite power supply PCB detects over current because of an error in a DC load, wire trapping, or the like, it flashes LED101 at intervals of 2 sec.
Error in High-Voltage Output Data
If the difference between the setting generated for high voltage from the microprocessor (Q401) on
the composite power supply and the actual control value is appreciable, the microprocessor computer
(Q401) informs the DC controller PCB of the presence of an error by means of high-voltage
error status data (serial communication) so that ‘E064’will be indicated.

All NP6030/6230 family copiers are noted for composite power supply problems. Poor solder joints are number 1. I have only replaced 1. They are easy to repair. Remove it,clean all the dust bunnies off the board, then get out your soldering iron and start touching up the solder joints that mount the transformers...they crack. Around the voltage regultors ,tranformers,transistors on thaat corner of the board resolder everything. Take you about 10 min. These power supplies are NOTORIOUS for cold solder joints....poorly wave soldered in manufacturing.Comment
