Good chance the High voltage power supply is bad. Not worth repairing. A new unit costs about 259.00.

Right side of printed page is faded

pull out your drum unit and look inside machine above where the drum would be. you should see a black assembly that runs left to right with a "****" glass. may need a flashlight. clean that glass off with a clean rag. sometimes toner "scatter" will get on glass and cause this.

let us know,

Error 7C

There's no manual for "machine error 7C" in Bro IntelliFax 4100. To fix this issue. You will need to pull out the toner. Note: the toner and drum are connected.....At the left corner of the drum. You will see a blue tab......You will need to slide the blue tab back and forth for 20th times....And put the toner back in its place.....This is just a temp fix but you need to replace the drum to have it working its fullest......

IntelliFax 4100 suddenly slow to print

If the dial tone sounds NOISY or SCRATCHY there probably is a phone line problem. Try changing the phone cord first. Are you using DSL phone service?

You have a very reliable fax machine.

Intellifax 4100 grinding noice

Probably caused by the toner cart. Only use genuine new Brother brand supplies. Remans fail quite often with Brother machines.
Possibly bad gears on fuser drive. But with the poor print quality, I suspect it is the toner.
