T520 24” plotter printhead seating

[Chris161190]

Hi all, 

I have a t520 plotter which seems to work fine but occasionally on start up I get a message saying there is a problem with the printhead and to either reseat or replace it, reseating the print head always fixes the issue enabling me to print but after a week or so I’ll get the same message again. I can live with the problem but ideally I’d like to fix it for good. Any ideas? Using a genuine print head and genuine inks. Printer was manufactured May 2017. Firmware is up to date. It has had a new printhead which resulted in the same message so don’t now think it’s an issue with the print head itself.

Thanks, 

Chris

Good morning,

I suggest to perform below fixes:

from Support Menu: how to access: enter into the support menu by pressing the power button for 15 seconds.

Perform OOBE Reset from Support Menu: 

1. Scroll down to Resets, and then touch Reset OOBE.

Perform Hard Reset :

1. Scroll down to Resets, and then touch Hard reset.
2. Enter the password 3746 when prompted to initiate the hard reset.

Perform Printhead startup condition  : 

1. Access 3.5 'Reset PHA Startup Condition'.
2. Type 'PIN' number 2873, and select OK.
3. if failed the plotter needs a service repair.

Thanks for you help.

I have tried these tests and get the fail message on the last test (Reset PHA Startup Condition)

The printer has a had a new printhead and gets the same error so i believe it is either the Trailing Ribbon Cable or the Carriage PCB?

Thanks 

Chris.

Hello,

Thanks for those details, I suggest starting with the carriage assembly (contain carriage PCA and trailing cable)

I will source the parts and report back if successful or not.

Thank you for your help.
