Infinity Subwoofer input signal mystery


Have you tried changing the connector leads? They can become faulty. Powered Subwoofers generally work off one connector from the amp. The Sub is a mono amp basaically. So all it needs is the main imput and an earth. One possibilty is that you have the wrong jack plug. Say a stereo instead of a mono, or the wrong size one!

The subs dont work amp makes a humming noise when i plug ut in


Hi
It's either connected wrong and there is an open ground or an IC has gone bad in the power supply. Check your connections first, then a reputable repair person can help.

Hallo there i have an error code 10-389on docucolor12


The code refers to a paper jam in the fuser, although this may not be technically correct, the fuser heats the paper and melts the toner if this process is comprmised it may slow the progress of the paper through the fuser. Try the 3 links below see if they help, if necessary power down the printer and disconnect the plug for 2 minutes to reset the sensors

Sub goes full blown loud when plugged in to wall


It sounds like a power supply failure. It needs to go to a repair shop.

Wrong cartridge


I had the same problem. The Canon web site recommends resetting the print heads, but this didn't work for me. Here's a link to their recommended solutions:

Wireless connection


Dear Sir/Madam,

I suggest you remove you net work and start again connect pc's and connect to internet at the same time
your sub net address is proberly wrong
255.255.255.0 is correct
255.255.000.0 means no internet

Thanks
Good Luck

Blown channel?


your amp try to protect itself from damage when he feels some trouble from your sub.-start by changing sub cabel and sub itself if it does not becomes ok.
if all above failed---you have serious problem in sub output stage and can be fixed in service center.
