Replace printhead error. printhead not recognized

HP Recommended
800 ps
Microsoft Windows 7 (64-bit)

Hi all,

I have an 800 ps 42 inch.

I got a message saying to replace the magenta printhead.

I bought a genuie OEM HP print head installed it and still got that message.


What else could be causing this error?

A local HP repair tech said it was then the printhead board.


They are available.. but I don't want to just start replacing parts$$$$.


Would you members have suggestions and/ideas to try.


Also, I have the manual, but how do I access the contents of the hard drive?


Lastly, I cannot fine the system maintenance utility anywhere. HP doesn't have.

Would someone be kind enough to email the utility or tell me where to get it?

The first step is to clean contacts:



There is an end of warranty date printed on the top printhead, check the date on yours is it still under warranty.

You might have printhead, printhead board, trailing cable or main board issue.

The content of HDD ( if you have it installed ) should not be the cause of printhead error.
