My memory ain't what it used to be, I just remembered this is the one I got an E064 after replacing the HDD due to an E601.
This is one of those gravy accounts that only calls in once a year the last 4 years, has less than 400k and I've only ever had to put in drum/fixing film/tires. The drum is only 6 months old and less than 50k. 2 months ago when they had the E601, after I replaced the HDD and booted up I got an E064. I remember reseating the connectors and doing a DC-Con clear. When I went to re-input the values the ones for the HV-TR were way off. But after putting in the correct values it took off and ran fine.
They only remember the blank copies starting a "couple weeks ago", but customers aren't the most reliable source regarding time. I think I'll start with the DC-Controller and hold off on the laser for now. Thanks Screwtape for explaining the E191.
E64-xxxx is the high voltage transformer.(HVT)
This can also cause blank copies.

I thought the high voltage functions were built into the composite power supply. Am I remembering correctly? =^..^=
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.

I believe your right. The presence of a high-voltage error is communicated by the composite power supply PCB. The Main cause for the E64. The contact has poor connection. The wiring is faulty. The composite power supply PCB is faulty. The DC controller PCB is faulty.
The service manual indicates the code is caused by a high voltage error. The output for primary charging, developing, or transfer has deviated from a specific voltage level. The two main areas to look at would be the composite power supply and DC controller.
E064 can be caused by the Developing bias value if its set incorrectly as well.
Check the setting of COPIER>ADJUST>DEVELOP>DE-DC in service mode. Compare this value with that of the service label. If the setting is found to be out of adjustment, set the value back to door specifications.
After making the adjustments, run some continuous copies to check for occurance of the code. Since this value is maintained by the DCON the same adjustment is required after replacement of the DC controller.
Check the steps below for troubleshooting.
1. Contact
Is any of the contacts of the primary charging roller, developing assembly, or transfer charging roller soiled? Or, is there poor contact?
YES: Clean the contact, and set it once again.
2. Wiring
Is the wiring between the contacts for the following normal: DC controller PCB (J301), composite power supply PCB (J136), primary charging roller, developing assembly, transfer charging roller?
a. DC controller PCB (J301) <-> composite power supply PCB (J136)
b. composite power supply PCB (J130-7) <-> primary charging roller contact
c. composite power supply PCB (J130-1) <-> developing assembly contact
d. composite power supply PCB (FT133) <-> transfer roller contact
NO: Correct the connection.
3. Composite power supply PCB, DC controller PCB
Try replacing the composite power supply PCB. Is the problem corrected?
YES: Yes.
NO: Replace the DC controller PCB.

i think due to the fact he has ran sky shots off and got no image on the drum does prove this theory to be ruled out. you need doc feeder open to take sky shots. but i know where your coming from, even had customers stick the copyright labels over the second switch and wonder why they got blank sheets.
I totally missed the skyshot mention,,, getting too old for this game, think I am gonna go drink some beers and get my weekend on!!!
do u receive blank copies from all paper tray/deck loaded locations
**Knowledge is time consuming, exhausting and costly for a trained Tech.**
if still having this condition, the drum could be defective or scan lamp or heat blanket for scan lamp is questionable
