Okay thank you for confirming.
These are 2 separate issues, and that would not work.
They do not use the same printhead, and are not interchangeable.
The 5010 error is a fault in the scanner system. The mp600 is beyond salvage at this point,
and even the mp500 is not going to be worth fixing. That is a 2005 model, it was designed for only a 3 year service life. Both of these machines have served their designed service life many times over and greatly exceeded any value that could be reasonably expected of them.
You would spend about as much to buy a new printhead (about $80) for it as you would to buy a whole new printer with updated features and a fresh warranty.
Even if you did replace the head, the absorber system will be at its end of life stage, rollers will be worn, cracked, dried out etc.
Neither printer is worth further investment at this point, and replacement is really your best option.
I can help you with finding parts if you'd like though, or with replacement recommendations if you'd prefer.
Best regards, ***** ***** for the news,
