Hi BabyM. I think you need new firmware update...Here is Canon site..: (Select your pc's OS before download)..Also can live chat with tech/support too...

If you have Vista..Just run "Add printer mode and let window search for correct printer port.
Good luck.

My HP Deskjet F380 has the latest printing software installed; it spools and is attached to my laptop in the correct USB port; but it doesn't print. The message is "no connection." It printed...


Verify that the USB connection is fully inserted in the back of the printer itself. If all is well there, try to think if you've run any updates on your laptop recently, or installed any new software that could be conflicting. If yes, try removing the new software or recent updates, and try a test print. If this still does not work, try disconnecting the printer, powering down your machine, starting it back up and then reconnecting the printer to the USB port. Sometimes you have have a glitch in the USB port that causes your computer to stop recognizing a device seemingly out of nowhere. If none of the above seems to help, it might be as simple as a USB cable that's become faulty. Hope this helps!

My printer will print and copy but won't scan. It


First, do you have the full-featured version of the software installed (installed on the computer before connecting the printer to the computer)? Second, do you have the all-in-one connected to a print server or USB hub? These can block the two-way communication needed for scanning. Try a direct connection. Also try a new USB cable and a different USB port (if you have any signal loss issues, it matters more with the scanner).

I hope this helps.

Konika Minolta 2400W can not connect. Clearly Windows XP sees it, and the driver is installed etc. When I plug or unplug the USB cable, Windows plug 'n play notices the difference. And the USB cable works...


Everytime you disconnect and reconnect the USB cable to a different port, unfortunately, Windows creates a new and distinct copy of the printer. You can see this by looking at the Windows Printers folder. The solution is when you change around USB ports, right click on the printer icon that is actually the active one (the other copies will be grayed out) and Set to Default. Then you can delete the other invalid copies. Then in the Minolta status software, go to the Display menu and Select Printer to change which printer is monitored to the correct copy. It's very stupid that Windows Plug n' play does this, but it does. So avoid change around USB ports on your Konika Minolta printer.

New Dell Inspiron connected to HP 820Cse printer. Won't print.


I've not worked with one of these cables before, but here's what I would do: Right-click on the printer icon and go to properties. You'll be looking for the tab that says "ports." Open that tab and see what port the computer thinks it's using for the printer. Chances it says it's using a parallel port, but it is in fact, using a USB port. I can't tell you which to choose without looking at what you see, but I think you might find one that makes reference to a USB port with a parallel connection of some type. Try clicking on that and see if your situation improves.

Connecting USB cannon mp610 printer to computer


You need USB A-B cable and use the USB jack lying on the back-right corner of the printer (not the front one - that is for connecting cameras).

Printer will not print


Some thoughts.
When you plug it into the computer that it will not print to, Does it tell you there is a new USB device found?
2. I am sure you have tried different USB ports on the computer.
3. Right click your printer to access the properties on the driver and select Ports and see if that somehow was changed.
4. Just delete the printer from the "printers" page in control panel.
Then click add printer and search for it.
5. Make sure the computer does not have a firewall that is blocking the printer.
6. Make sure there is no job error in the print queue.
7. Be sure the printer is selected as the "Default" printer. If there is another printer loaded on the computer, is the wrong one selected?
8 Make sure Print Pause is not selected.
I do suspect once you open the properties on the driver page you will find the problem. Unless of course your USB port or ports on the computer have failed.
