Getting this error a couple of times a day. Sometimes goes ago after a complete restart, sometimes it will hang around after a half dozen restarts. I have searched the forum and have done this so far: The bar in front that is supposed to turn has gears and switch senors on each end that i have cleaned(none was too dirty) and used canned air to help clean. (those areas are very difficult to get to, even with front and side panels removed). From previous forum "on the white ink side, there is a gear that "toggles" back and forth which moves the bar. This "toggle" mechanism is activated by a piece of plastic in the shape of a triangle. That triangle piece is known to become loose and fail. It snaps onto the end of a plastic bar. The bar has a tab that sticks out from the top of the frame-push it towards the frame, and make sure the plastic triangle is snapped in securely. The opposite end of this bar has a spring on it, and sometimes where it connects to breaks off." Checked and cleaned, gears and part good.
Anyway, done quite a bit of troubleshooting with no permament solution. Gave up for today.

turned it on today, worked like a champ all day!!??? Still would like some feedback if anyone has any. Thx!

This is an Epson generated error, no US Screen components cause this.
Since it works, goes away, comes back, it is not electrical.

What is the serial# of the machine? This tells me A LOT about your particular machine,
since I did the QC on most of them before they shipped from US Screen.

There is a white "gear" that sometimes was not removed properly on the CMYK side by
the "raise/lower" lever sensor to remove the ink cartridges. It is just "hanging" there and
had a belt attached to it which was removed during breakdown of the Epson unit.
Again, the serial number will tell me a lot, as I discovered this instance after QC'ing for a while.

The "exit roller" you mention that turns, rests on a white plastic bushing on the CMYK side of the
Epson metal frame. If it is dirty, or somewhat broken, will cause this intermittent behavior.

Observe the capping station side of the metal frame. There is a "triangular" plastic piece there.
It just snaps in. It could be working itself out, or be worn/broke and need replacing (again, an instance
of "works today, but not tomorrow"). It is connected to a plastic rod, which has a spring on the opposite
end. It controls the turning of the front bar (which is what this error is all about).
I have seen machines with a rubber band stretched all over the place to keep the tension on that rod
after the spring holder failed.

Check the CMYK side plastic bushing. Clean with HOT water. Inks are water based (cleaning solution
just keeps the head happy and prevents overheating-it's basically just Glycol "anti-freeze" and what
the inks are suspended in). Use water everywhere (HOT, ALMOST BOILING DISTILLED WATER) EXCEPT
FOR THE HEAD!! It WILL most likely blow if water is in it.

Grap the triangle piece and try to pull it out (gently). It should NOT just pop out.

Best of luck

Blazer SN: TJBE-B8066-0108. The exit roller plastic bushings look fine and smooth. Little to no build up(cleaned anyway).
The triangle piece looks good, spring good. Parts are clean.(cleaned them when i replaced capping station few months back). There was a little build up on the "outside motor" gears (under the triangle piece) and connecting gears so they got a good cleaning also.
FYI: on the cymk side under the exit roller bushing is a rectangle shape opening (stamped out of the metal siding) thru that opening i can see a white gear about 1.25" dia.
FYI: I have the 4880 service manual and a 4880 field repair guide for reference if needed.
Also: total Prints on the LCD show 2,678 (I don't think i did even that many)

Thx again for all your input!!! - Ralph

You have machine #66 out of approx. 350 that were built.
The "gear" in question does not have teeth on it, it was for
a belt that fit on it. It is approx. 3/8" diameter, and sometimes
was left there during breakdown.
Check the sensor on the CMYK side, there is one for the exit roller.
Since the issue comes and goes, it may be loose or dirty-clean it with alcohol.

Ok will do. I saw the sensor when I was trying to diagnose the problem the other day. That booger is hard to get to! Had to remove the front skirt, carts and cart faceplate just to get a good look at it. Anyway, next time I have the error, I'll throw a meter on the switch to see if it open and closes.
Quick sidenote: on the lcd, the service only button, mine is on (down) and several posts here say it should be up (off) but my lcd will not turn on it that position?? Thx again for the help, wish i can return the favor some how.

The "service only" button is just the Epson on/off button.
Us tech's can tinker with it to troubleshoot other issues.

The reason it should normally be "out" or "off" is so the US Screen
components work in a way where you don't have to depress it everytime it starts up.
Once the bed moves to the front, enters a sensor, there is a black relay taped to
the capping station side frame, which should "tick" and power up the LCD automatically.
Normally, having the button depressed the LCD turns on before this happens and therefore
confuses the DC control board.

Some machines do not work like they are supposed to in this regard, and only seem to
operate normally with it pushed in. We had one such machine like this at US Screen,
replaced EVERYTHING on it, and it still did not work correctly.
We kept it to do testing of inks, etc. since we could not fix it and would not refurb and sell it
in that condition.

If yours works in this manner, just keep using it that way, it should not become a problem.
I have seen about 4-5 machines (out of almost 700) work in this manner.
