Disassbembly of an HP OfficeJet 200 Mobile Printer

Could someone provide instructions on how to disassemble an HP OfficeJet 200 Mobile Printer?

Specifically, the case needs to be opened up so that an ink cartridge leak can be completely cleaned up.

Also, the printer will no longer turn on (or charge the battery) when plugged into an AC outlet. It will still run on battery power.
