HP CDK LAserStation M605 - Error 59.05.50

[KDservices]

Hi,

We recently replaced the rear drum of the HP CDK Laser Station M605 printer. Since then, we have been encountering the error message 59.05.50, despite all diagnostic tests showing no issues. Why is this error message appearing?

Thank you.

This error is a drum motor startup error. That means either the motor has failed or the cartridge is defective and the motor cannot rotate it. Try a different cartridge. If you get the same error you will need to replace M102 motor.

Hello,

Thank you for your prompt response. I replaced the cartridge, but I'm still experiencing the same issue. So it seems to be a problem with the motor drum not spinning, although the drum itself is also new, I replaced it recently! It may be a more serious issue. I've seen some videos on YouTube showing a problem with the printer's motherboard!?

Thanks,

Can you clarify what you replaced? The drum on this printer is part of the toner cartridge and that is the error you are getting.  From your reference to replacing drum at the back, that would be the fuser and is not related to this error. It is the toner cartridge drive motor.

Indeed, you were absolutely right. I replaced the rear drum, so the fuser unit is not the cause of the problem. Then, I tried with another cartridge, but I still have the same error message 59.05.50, along with another message saying "maintenance kit". Apparently, the issue is not with the cartridge, so I am a bit lost!

No the issue is likley the cartridge drive motor. If you have replaced the fuser you can reset the maintenance count, it is not automatic on this model. But that will have no affect on the other issue. I suggest you go into troubleshooting and test the drum motor.

Error code 59.05.50 on the HP CDK Laser Station M605 printer indicates a problem with the drum motor assembly or the drum itself. Check for proper installation, inspect for damage, update firmware if needed, and ensure no electrical issues. If problems persist, contact HP support.

thank you for all your responses. However, I have no idea how to reset the maintenance counter, as you say it's not automatic on this model. Also, how should I proceed with troubleshooting the motor drum and testing it? I am a programming engineer with no training in printer repair.

Thnak you so much.
