Hi, you can try thie steps to see if it will work out for your copier Cycle the Power The easiest way to reset a copier is to simply cycle the power. Turn it off, wait for at least 10 seconds, then turn the power back on. Note that 10 seconds may not be enough for the copier to reset. You may have to give it time to cool down completely before turning it back on again. This works because copiers can sometimes get stuck while performing a function, and by cycling the power, you're interrupting the process and putting the copier back in its original state. Replace a Part According to the SER FAQ website, the copier will be unable to continue its process if it finds a problem in its function, like a broken or worn out part. Because of this, the copier may need to be reset. Replace the part in the copier before trying to reset it. Some copiers will then begin the reset process automatically, while others may need to have the power cycled. Delete All Settings According to the Copytechnet website, you may have to go into the copier's interface and delete all of the settings by hand in order to reset it. For most copiers you'll log into the administrative account first. Then, go into user tools, system settings, admin tools, and then address book management. Select each entry and delete it. Resetting the copier by hand is more tedious than the other methods listed here, but it is just as effective. After reset, if won't reset, it might show you this display(H-1). .H-1 means an open thermal fuse on the upper fuser roller. Remove the cover on the fuser rollers and you will see a ceramic fuse located on the top plate. Check the fuse for continuity. If bad replace it with one with the same temperature rating, ( or close to the same ) Sometimes you can find them a radio shack. If not email me and I will send you one. If you order the fuse from sharp it is pretty expensive. If the fuse is good check the lamp in the upper fuser roller or the upper lamp triac. 99% of the time it is the fuse You can also try this method, How to reset user tool settings to default! System Setting Reset The system settings in the UP mode can be reset to their defaults. Use the following procedure. 1. Press User Tools/Counter .2. Hold down the '#' key and then press System Settings. 3. Press yes when the message prompts you to confirm that you want to reset the system settings.4. Press exit when the message tells you that the settings have been reset. Copier Setting Reset Use the following procedure to reset the copy settings in the UP mode to their defaults. 1. Press User Tools/Counter . 2. Hold down '#' key and then press Copier/Document Server Settings. 3. Press ?Yes? when the message prompts you to confirm that you want to reset the Copier Document Server settings. 4. Press exit when the message tells you that the settings have been reset. Good luck.

What does transmission report cdoe NG290000 mean on a Sharp MXM363n MFP When trying to send a fax?

My recommendation would be to hit the speaker button when sending a fax to hear why your fax wont go through.

When you hit speaker you should have a clean dial tone, then when you start dialing and the tone stops make sure you don't have any static or noise on the line.

There are several reasons you might get a NG error. One is the fax line you're trying to send to is busy. Maybe it's a phone line not a fax you're trying to send to. Maybe you need to dial a 1 or 0 for long distance, maybe your fax line has noise on it.

Using the speaker can help troubleshoot what the problem is.

I can not send or recieve faxes. Ran fax test

Cox Cable is pretty much the same as comcast's and vonage's services. HP fax machines have had HUGE compatibility issues with those types of services, and may be that they did something to their service that caused your fax to stop working.....

Other than that call HP and see if they have any troubleshooting or Diagnostics that you can run, but I ran in to these problems with HP faxes all the time while installing comcast phone service, never knew WHY it didn't work, just that HP doesn't work on that type of least certain models...Also maybe call COX and see if they did anything recently that could cause it to stop working....

Cannot receive faxes

Hello, my name is Curtis, and I am a Customer Service Rep. for Sharp Electronics. If you cannot receive faxes from multiple machines than you might want to check to make sure you machine is first set to fax mode, also check to make sure than the phone service for the machine is analog and not digital. The machine will not work well with digital service. You could attemp a work area reset on the machine, the procedure for doing so is to First take out all the paper, Second unplug the main power cord, not the phone line. And Last after about 30 seconds to press and hold down the start and stop keys while plugging the machine back in. Once it turns back on you can replace the paper. If there is still a problem please contact Sharp at 1-800-237-4277.
