PLATES NOT REGISTERING AND HAVING LINES ON THE PLATE IMAGE

[Aliwakekani]

hie everyone am having issues with my ECRM MAKO 4 CTP IT GOT STRIP LINES ON THE IMAGE AND AM HAVING A MIS REGISTER ON MY PLATES
..PICTURE PROVIDED FOR STRIP LINES BELOW

What is imaging direction?

hie Chris, what do you mean by imaging direction

 

[ChrisZ]

Lines are in fast scan or slow scan direction?

Lines are in fast scan or slow scan direction?View attachment 294391

Slow can direction

 

[Aliwakekani]

Slow scan

 

[ChrisZ]

You need to clean ribbon belts both sides. Flat belt and kapton belt. Also brass wheels surface and drive motor shaft.
Check tension, should be the same both sides.
Clean transport rollers.

It is critical for that machine and usually should be done during preventive maintenance every year.

 

[Aliwakekani]

thank you Chris will update once i do the maintenance

 

[Aliwakekani]

hie ChriZ did the maintenance and cleaning and checked both my tension..
the machine only shows lines now at the end of the imaging i think 90% of the image will be okay but that 10% it still have lines and a bit of streched image
Today the laser had a report of over temperature without imaging anything

 

[ChrisZ]

So problem with plate transfer still persist.
Only cause are motors, belts and tension. You can run encoder test in diagnostics.
Laser temp: TEC cooler and cooling fan need to be checked.

[Aliwakekani]

thank you Chris for the response:
how do i run the encoder test

 

[ChrisZ]

When online press and hold next/prev/menu
While in service menu go to encoders test and execute it.

ENCODER A FAULT, ENCODER B FAULT

 

[ChrisZ]

There are glass disks inside encoders, might be dirty. Sensors as well.
Clean them with photo lens cleaning fluid. No isopropyl alcohol, leaves smudges.

 

[Aliwakekani]

okay thank you, will do the servicing and cleaning

 

[Aliwakekani]

INSERTS ARE PICTURES OF THE IMAGE PRINTED BEFORE WE RAN SERVICE MENU
SCRETCHED IMAGE BUT LINES WERE NO LONGER VISIBLE

 

[Aliwakekani]

Can you kindly send me your email on [email protected] where i can contact you when am on the machine...
thank you

 

[Aliwakekani]

AM NOW GETTING THIS ERROR, WHEN I SWAP THE MOTORS THE OUTPUT CHANGES TO INPUT ROLLER TIMEOUT

 

[ChrisZ]

Movement timeout:
• Check drive belts for proper installation and tightness.
• Check drive encoder for proper installation; ensure collar is secure on drive shaft.
• Run the internal encoder test.
• Verify cabling between main drive motors, encoders and main control board
• Replace drive encoder.
• Replace drive motor.
• Replace main control card

Stretched image - whole plate equally or just partial?

Thank you Chris for your response...streched image is just partial
