Question about Brother IntelliFAX 4100 Laser Fax
Hi, I took the plunge, disassembled the machine and found the broken brown fuser gear.Scavenged an intact gear from a spare fuser assy from an old model 1240 printer.The first few prints were perfect, but then progressively bad double/repeat faint images.Is the red roller bad?Heating element?Thermistor?The red roller in the 4100 seemed to have a bigger diameter than that in the 1240 (indication it is bad?).Should they be the same? thanks
Although it fit the broken fuser, it does not mean it's ok.
1-they must have the same number of teeth ( diif. gears have diff. amounts of teeth)
2-it must be the same diameter ( so they can mesh together, otherwise it's touching the tip of hte teeth and may be skipping.
But I'm not sure the double image is coming from there, it would jam the paper because the timing is off.
Anyway you need to eliminate the obvious then see what happens, I think you said you had another tonertry putting that in, if it doesn't work then change the gear for the correct one.
