HELP e074err Y Current

this is a y motor error.

Could be the motor, belt, belt tension or encoder.

Take a clean room wiper and some denatured alcohol and carefully clean the encoder strip at the top of the rail. Sometimes, ink and or dust will make it difficult for the carriage to know its location

It is what looks like a clear strip of plastic on top of the y rail, under the top cover, you dont need to remove the top to get to it.
It actually has on it a bunch of virtical lines that tell the carriage where it is at, at all times.

 

I had this exact same thing happen on my Junior a couple years ago. What happened to mine was the pulley on the Y motor had come loose(they are glued on). How I finally figured it out was that every time it would do that i could hear a slight rev up in the motor then it would give me the error. The shaft was slipping in the pulley. I was told you have to buy a complete motor assembly but I took my motor off and used the best loctite I could by and glued it back on and it worked great. Make sure if that isyour problem that the pulley goes on in the exact same location on the shaft.

 

66 is just a y motor error, where 74 is y overcurrent error.

Still could be the motor, belt, belt tension or encoder.

No way to tell from here which.

check for binding, and check what Graphics2U posted as well.

 

Do you have a service manual for it?

 

Check your PM's

 

If it stops at the same area everytime, it could still be the timing fence (the clear encoder on top), could also be the encoder sensor.

I dont know of a real way to check the motor, when you seem to be getting random errors. It is a servo motor, though.

You could run life cycle test in maintenance mode if you find get a manual.

 

Great! Hope you get it fixed. Just use some good loctite and let it dry overnight. Did you get the manual ok? It will tell you how to tension the steel belt when you are done.

 

Great to hear your up and running

 

Could you please tell me how to do this ?

TY

 

Well It calls for a special tool to measure the tension which I did not have but what you want to make sure of is the 2 screws that adjust the roller or pulley on the left end of printer are moved at the same rate. Count the number of turns of the screwdriver to be sure the belt will run evenly. Then tension should fairly tight but not too tight or you risk breaking the steel belt. I don't think that is all that critical as long as it does not slip. Then roll the print head back and forth several times and watch the steel belt on that pulley to make sure it doesn't run off the pulley. A slight movement up and down is alright but if it keeps working it's way one direction or the other adjust either the top or bottom screw in or out depending on which way you want the belt to move. It's kind of trial and error on that part. Then I actually printed a little with the covers off and made sure the belt was staying on the pulley. Hope that helps.

 

I am getting E074 CR2 Current

:-(


Update:
Ended up being a bent clip that keeps the print head over the capping station.
How it got bent is a mystery!

 

Exellent Graphics2u !!!

Thanks!
