First of all, determine the extent of oxidation on the aluminum surface. If it is determined that the surface is in relatively good shape, i.e. light oxidation, then skip this step and move on to polishing with Flitz.
Q: how long can a usb printer cable be? I am trying to connect a HP laserjet 2840 to my iMac with a USB 2.0 cable that is 25ft long. The computer does not recongnize the printer or that it is connected when I plug them both in. The same 25ft cable works fine when connected to my other HP P1006 printer. The HP 2840 works fine when I use a shorter usb cable.
Length Limits of USB Cables One of the main problems that many people face with USB devices are the length limits of USB cables. The length rules stipulate the length of the cable at 5 meters or 16 feet for USB 2.0 devices and 3 meters or 9.8 feet for USB 1.0 devices.
