Need Help My printer keeps stopping in the middle of printing

[BLU]

I have a Mutoh 1204 value jet printer that keeps giving me this error (E074 err Cr2 Current) Which makes the printer stop right in its track of printing

Try cleaning the encoder strip.

There are 4 head carriage bearing guides - shiny chrome strips. You can see 2 of them from the front on the Y guide rail. The other 2 are directly behind them on the Y guide rail. Clean these with a swab and alcohol until totally clean. Excessive resistance from ink and dust buildup on these guides create an additional load on the CR motor and cause it to give the E074 error.

If all of your mechanical checks are in good order. You dont have any blockages, the strip itself is in good order and clean, your guide rail isnt dry (use white lithium rail grease if it is) then you might be looking at an electrical error. Getting too much or too little power to the motor even in small amounts will trigger the error just like if you basically had a paper jam. Im mostly a roand technician but it should follow some of the same logic. There should be a Hub of sorts that collects all of this information and sends it directly to the mainboard for processing. So your radial (circular) encoder disc for the stepper motor and your encoder strip for the scan motor should all plug into Something. Either before it gets to your mainboard or into the actual mainboard itself. Most likely youd have some pin connections and or ribbon cables connecting these. Id pull them and give it a gentle cleaning and plug back in to see if it stops the issue. If there are no mechanical issues in that regard and the cleaning doesnt work then the controller for the scan module would need to be replaced. Bearings dont typically go bad unless youve been running them without maintenance for a LONG LONG LONG time. If you can slide the carriage head back and forth with ease and no rocking back and forth they should be in decend condition.

I've cleaned the encoder strip And put everything back together and I tried to print a 4 X 2 sign and once again it stopped in the middle of printing

Clean the guide rails...

Clean the guide rails...

I forgot to mention I did clean guide rails first...

Do you have a video on this

 

[Jim Hancock]

No on the video, but it's straight forward - clean the 4 chrome strips with swabs and alcohol until clean. See pic. Move the head carriage back and forth the width of the machine, it should move freely. If so, as mentioned above, very lightly grease the chrome strips with white lithium grease. If that doesn't work, most likely the CR motor is dying.

OK I have those cleaned but where can I get that lithium grease from and I truly believe that my CR motor is really dying

Clean them again.
