Anyone know what would cause "Call for Service E3 Drum Error" or a
repair manuall for the same.
I have stripped the thing down fixed a couple of clutch problems and
unseized the fuser oil rollers, changed the otp belt, fuser oil bottle
and roller.
I still think the fuser oil rollers are a bit stiff but how do you get
access to the bearings behind that black plastic cover. Taking off the
top panel does'nt seem to help get to them.

It always happens when the printer has been in energy saving mode for
a while. The first time the printer warms up I get the error after I
open the top cover and put it down again no problems at all. It will
print a whole paper tray until it goes back into enrgy saving and
cools down again.
I'll try your suggestions and see what happens thanks for the advice

First of all is this error persistent or does it apear at random intervals ?

E3 drum error is usualy caused by a heavy moving opc-belt.
The drum motion is detected by a a sensor located at the left side of the
drum with an encoder disc. You could check by looking at the drum from the
rear of the printer and see if the sensor is properly located.Also there is
a possibility that the belt does not rotate properly caused by a defective
gear in the black gearbox on which the main motor is attached.

About the fuser unit being stiff, this has nothing to do with this error and
is normal for this fuser.
if E3 is a persistent error and you suspect the fuser unit you could remove
the fuser clutch (the one with the blue connector) and see if the problem
remains.Do not remove the connector itself because that will result in an
fuserclutch error, just remove the plastic ring and slide the clutch out.

If you realy want to open up the fuser to access the bearings (I would not
advise it though)
you will have to remove the two side covers, the oil pan,top panel and
lamps.
Once done there are two screws on the frontside where the oil pan has been,
these two hold the front and pack part of this unit together.

Does this only happen after it has been in energy saver or do you get the
same problem after a power on when the fuser is cold ?
If this only hapens after the energy saver I guess you don't have to suspect
the mechanical parts of the printer but a problem in the controllerboard
area especialy if you're able to print a whole tray.I know of a problem
related to the energy saver in this printer but usualy the printer won't be
able to wake up from it.
What firmware level do you have installed ?
what version engine controller prom do you have ? (small controller located
on the left side of the printer on which the qms controller interfaces, is
should be version1-4).
If you disable the energy saver do you still have this problem ?

Seems like it only gives the error when in energy saving no problem at
all starting from cold switch on or printing after being idle for an
hour or so with energy saving disabled.
I found the engincontroller prom after I hade the interface out and
looked behind the metal panels I found the board laying on the desk
it is 1-4 after I have reassembled the printer I'll get the
firmware number from the LCD

Ok, This narrows it down to three possibilities:

1) the power suply is not restoring power to the controller after a wake up
signal from the engine controller. This is not likely but luckily it's
measurable.You could compare voltages on the square 4 pin connector from
power suply to engine controller during normal operation and after energy
saver just before failing.

2) Engine controller is not passing power on to the qms controller after a
wake up signal
This is also not likely ......At least I assume some motors will come to
life after a wake up call.

3) Qms controller has failed to wake up some internal components.
This seems to me like your problem.
It may be caused by a firmware bug but I assume this wasn't a problem
before.Just to be safe you could update to the latest version (v312 as far
as I know).
It could also be a electronic failure in the stand by circuitry of this
controller.In this case you'd be better of disabling the energy saver.
Replacing this board will be expensive and trying to repair it is too
complex without proper documentation (and this documentation is not
available)

Looks like pulling the lefthand side of the printer apart has fixed
the problem, I'm not getting the error anymore.

Seems like it only gives the error when in energy saving no problem at
all starting from cold switch on or printing after being idle for an
hour or so with energy saving disabled.
