  • Elly Apr 30, 2009

    Iv been trying to print something that is 2 pages long. It prints out the 1st one fine, then the 2nd one comes out really bad, like the inks low, but I just refilled it maybe 2 weeks ago.. Theres no way its empty.
    The power LED light blinks continually, when I press it, nothing happens.
    When I turn off the printer and turn it back on, nothing changes!
    This has happened continually for the past week, but only when I try to print out something thats 2 pages or more.

Why my brother printer goes offline?

Is this a network (cat 5 cable) printer or a USB printer? Continual unplugging of a USB printer can cause issues where it will not recognize that device in which case you need to uninstall the printer and plug in to have Windows reinstall. If it is a network printer then you can either Repair or check settings by clicking "start" and type "control panel" (open when the control panel APP shows. You can "repair" or "troubleshoot" by right clicking on printer in "view devices and printers" or check "port" and make sure it shows the IP address of your printer and not "WSD". "WSD" is a windows chosen driver and notoriously has intermittent connection problems causing VERY slow printing and "offline" messages.

Blinking lights, ''offline'' status - hp deskjet d2360

If it used to work, then try unplugging and reconnecting the AC power cable for USB scanners. No guarantees at all, but it may work. Unplugging and reconnecting the Firewire cable in XP also sometimes works. Give it a few seconds to be detected.

It just started blinking and says the printer is offline

If it says printer is offline, it usually means your printer is not connected to the PC. Blinking printer light means there is a problem with the printer (usually paper jam) or with the ink. Check the ink cartridge. Take the cartridge out and put it back in. Make sure you also check the USB cable that goes from your printer to the PC, take it out and put it back in. Also, try to turn off the printer, take it out of the power outlet for 30 seconds and put it back in. If you have a power strip, don't use it, try plugging it directly to the power outlet on the wall and turn it back on.
