Scrap n Repair: HP Deskjet Ink Advantage 2135 Leaked Ink, Disassembly and Cleaning

Found this printer from detrash. Tested with printout problem where ink is scattered on the paper edges. Upon disassembly, I found that the ink is scattered all over the internal parts of the printer. This could be due to the ink cartridge leaking or the printer being moved sideway, Upside down. The unit was stripped, cleaned, and reassembled.
