Requesting service manual for Hp printer F4280 AIO

[delirium]

I'm kindly requesting the service manual and/or the schematics diagram for the HP printer F4280 or F4200 series or for any printer that would be quite similar to the above (like F4480). I own the F4280 which I bravely took apart in order to clean it inside and assembled it back again. But after that the printer doesn't work properly (I wonder why ). I've searched the internet for the service manual and I only came across with one that is sold for $162. Any help/advice would be also greatly appreciated.

Thank you very much.

Regards,
Melina
