Strange shadow effect

[midnightmadman]

Something else. When I turn the printer off it gives me the alert to change head gap to low. Even when I have it set down at low

 

[midnightmadman]

Wow ! I unplugged the head cables and plugged back in. One seemed to be tiny put unseated. Thanks guys. Hope this is all it was. These machines have a mind of their own

Ink dust can be caused by too high head height. But not duplicating of image.

Thanks. Probably has been resolved!

 

[midnightmadman]

Very upset to say this prob just came back again. No rhyme or reason. Seems to be something isolated to the black for some reason

 

[midnightmadman]

If you look at this nozzle check you can see the colors are overlapping in spots

 

[midnightmadman]

Unplugged machine for an hour. Powered back in. Did a nozzle check and it’s perfect again I’m puzzled!

Sounds like interference. You might want to check all the connections. Either something is loose and making a poor connections, damaged or a board might be on the way out.

Thanks. Last time I pulled the head cables out and put them back it it seemed to fix it. But why would shutting it down fix it this time ??
Is there a possible electric issue with the actual outlet. Maybe grounding or stray current ?

I'm not familiar with this particular printer, so I cannot say for sure. But it does sound like either electrical interference of some sort or a board is going bad. Restarting might help it because you are cutting the power for a moment and resetting it and once you get going, whatever the cause is builds up again and causes your problems. Might be time to change the cables and see, as they would be cheaper then the boards.

Might want to replace those ribbon cables also, might have a little kink in them somewhere.

This ^^^^^

Ribbon cables are a consumable. The wire in them is finer than hair and they can only take so many bend cycles. I replaced them on my Roland when I started having print issues. Problem solved. At some point I know I will have to do the same on my new printer.

Hi guys. I’m getting a weird shadow effect when I print. If you look at the image these two gray bars should be just two gray bars. Everything I print has been coming out this way. It is double printing for some reason offset by about 1/2” to the left

Clean your encoder

 

[midnightmadman]

The encoder strip or the disk ? Or both?

 

[midnightmadman]

Does anyone know the length of the long ribbon cable that runs along to top or a link to the right one ? It’s a 1204
