Service required error number 00010033. The sensor

Epson 4800 Stylus Pro - Service required error number 00010033. The sensor does not appear to be dirty. Is this something that I can fix myself? I have shifted the printer head then unfastened the sensor with two screws. Everything looks clean, but on turning on the machine the error still comes up. I hate to think of getting three additional guys here to lift the printer the printer for transportation and have it out of service for a month or more.

    After many attempts to address the issue, I took my printer in for repair. The facility sent it to Epson since they did not have a very expensive piece of needed equipment. Epson ended up replacing the heads resulting in a new machine. They also sent a complete set of inks because one of their people indicated the printer was sent damaged to them which was not the case. Sending the inks at no charge was the apology for their mistake. The total invoice was something like $550.00 and a turnaround time of about two weeks.

    I will be printing your solution for future use.

Just fixed this today. Ink from head cleaning is dripping down on the idler gear that runs the exit rollers. The ink gets thicker as it dries and makes the idler gear (attached to a swing arm) to not sweep up into position. The sensor on the left does not trigger, causing the error. Follow the epson_4000_field_repair.pdf to remove right cover, push down on green head release button to move printhead to left. Remove one screw that holds recovery funnel (left square plastic). Have fun cleaning partially dried overflowed ink in gear area. I removed the E-clip and removed the idler arm to clean completely. If adventurous, remove 4 screws holding print capping mechanism (way down) with a long driver and move slightly to the right to allow the two larger nylon gears to be removed. Clean all you can including the funnel and reassemble. Be sure to open up the drip slot from the maintenance tank side so the problem does not repeat

Okay looking at the front of the printer where the paper comes out, it is the rotating rollers that roll the paper out,,,, it is the sensor that is attached to this that causes the error.
It would appear that if on start up if it rotates it is probably a problem with the left one, if it doesn't rotate at all maybe the right. As if you lift up the right and side of the rollars to deactivate the right switch the error comes up straight away. Try this and see without taking the silver front cover off,,,,,, it is an effort!
A quick fix might be to fiddle with the rollars bump it up and down on start up to help the sensors activate. This worked for me once.
In the below people mention a sensor all I see is the micro switch.

I think I might know what your problem is:

- You need to look at the *left* end of what used to be the rotating paper-exit roller bar (US Screen removes a bunch of stuff from that bar, but it still has to be there so it can rotate during startup to trigger the sensor).

- Power off the printer.

- Remove the front stainless trim panel around the CMYK tanks so that you can more easily get at the sensor inside. Then remove the yellow ink tank.

- If you look in and down just to the right of the yellow ink tank, along the end panel of the printer assembly, you will see a small black rotating cam at the end of that bar which moves a small sensor switch up and down as it rotates. You can easily roll the bar around by hand to see how it works.

- Check for dirt (shirt lint, etc) which might be interfering with the little sensor ... what looks like a small black microswitch with a white arm sticking out of it toward the rear of the printer and up against the rotating cam.

- It might help to hit that sensor with a gentle blast of "canned air". Make sure the sensor arm is free to move up and down. Be *very* careful you don't damage the sensor ... it's rather delicate!

- Make sure that you rotate the bar so it is sitting flat side down and the cam has allowed the sensor arm to move upward.

- Replace the yellow tank and power up the printer. It should be fixed unless the sensor itself has failed for some reason. If things are ok, replace the stainless trim ... be careful not to over-tighten the hex-head bolts or you'll never get them out again Service required error number 00010033. The sensor - smile.gif

I hope this helps. This is a very rare problem, so not a lot of folks have hit it.

Good luck!

Communication error typically means that your printer and computer aren't talking. Assuming you're using a USB cable, try a replacement cable, in another socket on the computer.

Epson Pro 7600 Service required error

You need to be able to clear the counters in the printer that tell the printer to stop working.
In order to do that you must

1. Turn printer off
2. you must hold down the "Paper Source, Paper Feed, Select Feed, Cut/Eject" buttons all at the sime time while you turn the printer back on.
3. From there navigate through the menues to clear the counter that pertains to you or all.
(Error 00000101 is pertains to the print head motor)

Word of warning -
Those counters can be a pain as they cause the printer to stop working however you do need to get your printer serviced by a tech as soon as you can because the error is a warning, reset the counters lets you finsih a job, but if it goes unserviced too long it will actually break down all togther.

So even after you rest the counters you absolutly must get your printer serviced soon.
