Re Canon Fax B840. When I attemt to send a fax it gets to submit but doesn't send the fax. The activity report says NG. How can i fix this problem

most printer in the market has the same standard setting for the fax.
u can set the report many types for many user's purposes, some people want to save paper, save ink/toner, so they dont need report if the fax is sent but only print report if the fax is not good(NG or not sent)

it can be set to:
report off--means report will be print out only if the fax is NG
report off+image--means report will be print out if the fax is NG + the image of the page that is not sent(so we know which page is not sent through the image)
report on+image-- every fax activities( sent or not sent) will be reported, which is not recommended
etc....

how to set is depends on your printer, just go to the menu "FAX" and look inside the menu.

You need to apply Canon's firware update at http://www.canon.com and search for fumx310swin1040en.exe if you have Windows or for an iMac the file is MX310 series Firmware Upgrade Utility Ver. 1.040 (Mac OS X) with a file name of fumx310sosx1040en.dmg

Hello.

NG means: Some or no pages sent.

Check the paper feeder to see if the page is pulling through.
Listen to see if the fax line "sounds"like it is working or if you hear dialing or not.

Hope this helps.

It means No Good or Not Good, fax was never received for a number of reasons.

Yes,it means the fax did not go through,it will show OK on the report if it was succesfull

try this step to send your fax:

NO GOOD (USA) or NOT GOOD (ASIA)

NG 070 = Issue: ERROR LCD: CLEAR ADF, DOCUMENT TOO LONG
Solution: Reduce the length of the document

Reduce the length of the document to within 14" (356 mm).
