Hi all - I have an Epson Stylus dx7400 scanner printer. I need to replace the blakc ink cartridge, and am having a problem accessing the actual cartridge. When I turn the machine on, the print head move from the right hand side across to the left and back again; I need it to be in the middle in order to be able to lift the top of it up, to get to the 4 ink cartridges. According to the manual, after pressing the power on button, I need to then hit the stop button, but this doesn't move the ink housing from the right hand side, where it rest partially under the printer outer case, and is inaccessible. Anybody using or familiar with this kind of printer, that can tell me how I can get the ink housing to stop in the centre, so I can lift up it's top, and replace a cartridge pleas? Thanks - Andy
