  • bilky May 13, 2008

    someone from pasha's site was giving me instructions as my office 5500 hp fax machine will not send or receive faxes.....she was giving me some instructions and instead of waiting until she had finished with all instructions I followed the first few steps, which was to unplug the machine as the outlet and then replug in order for the computer to initialize.....of course when I did this I lost connections with pasha....also unplugging and replugging did not help the fax machine to be able to function

Plug a regular phone into the wall outlet and listen for a dial tone,

Make sure the phone cord is plugged into the LINE port of the fax machine.

We cannot send or receive a fax - no settings were changed


If you can not send or receive faxes the machine most likely is not getting a dial tone.
Start by unplugging the telephone cable from the machine and from the wall jack and then plug it back in. Make sure you are reconnecting the telephone cable to the correct jack on the fax machine.

If this does not help, try using a different telephone cable or try connecting to a different wall jack.

If there is still no dial tone and the machine does not work, I recommend trying it in a completely different location. If this still does not work then you can safely say that the machine is broken.

My Hp officejet 4255 all in one is showing error 0xf0af8005.The printer carriage is hard up against the left side of the carriage rail. Can't fit cartridges. Help!!

Per HP, this error message indicates an "internal condition" and requires reset. In order to reset as they direct, please do the following:
  1. Disconnect the Universal Serial Bus (USB) cable from the back of the product, but leave the product turned on.
  2. Open the cover of the product and remove the print cartridges.
  3. Close the cover and wait for the Insert Ink Cartridges message to display.
  4. Disconnect the power cord from the back of the product and wait for one minute.
  5. Reconnect the power cord. If the product does not automatically turn on, press the Power button.
  6. Open the cover and reinsert the print cartridges.
  7. Close the cover. If prompted, print a calibration page.
  8. Reconnect the USB cable, and try to print a print job from the computer.
However, it sounds from your description as though there may be more to this problem, as you have indicated "can't fit cartridges". As this seems to indicate that perhaps you have no cartridges in the machine at present, please post further details.
If this information assists you in resolving the problem, please take a moment to rate the solution at a "FixYa" level. If you do not feel that you can rate at a "FixYa", please post back with more information regarding what has occurred subsequently and/or more details regarding the situation, and I will gladly help you until we have reached a definitive solution. Thank you for using and rating FixYa!

Brother Intellifax 600 fax machine no longer receives faxes

my Brother Intellifax 600 just started doing the same exact thing out of the blue. I have no desire to get another fax machine as 99% of our incoming faxes are Junk. I will not pay for ink or toner for junk faxes. I would say in our business, it is needed no more than 4X per month. I will tear into the machine in the next few days to see what the problem is and come back and post it here if I have luck

Fax line is busy

check the hand set is correctly seated on its cradle.
Check the Hook button on the front of the machine.
Disconnect the fax machine from both the phone and power lines for several minutes, reconnect and try again.


I have included a copy of the users manual in case you are missing yours.

Hope this helps

Xerox ducu centre 420dc wonte come to ready. no error code turn it off and on clears sometimes but takes a lot of trys

When the machine comes on. There is a cable that runs from the scanner to the processor. When the machine is ON, unplug it and re connect it . It should reboot. That cable most likely needs replaced. But try disconnecting and reconnecting it with the machine on.

Open cover message

Several possibilities with that. Trying to think what order to try things.
In your menus or settings, there should be a way to clear the memory. You may have software corruption causing that issue.
If you do a memory clear, you will have to enter your date, time, phone number and company name.
You may have a loose connector to the interlock switch or on the circuit board. You would have to unplug the machine and disconnect and reconnect the connectors.
one of the cover interlock switches itself is defective.
Could simply be one of the covers is just twisted or warped.
Possibly one of the cartridges is not seated and arching, corrupting the memory.
After that, there very much less likely is a bad circuit board, ( very unlikely).
The reason I suspect memory corruption is because you have to unplug and plug it back in to clear.
A faulty switch shouldn't make you remove and reconnect power. But, stranger things happen...
Good luck and let me know whats up. Maybe I can offer more ideas once you check theses items. I know , it's a lot.
