aficio 1075 sc 544/541

[mahabub]

hi everybody, i have one copy machine aficio 1075,it was given massage sc541,after i checked the m/c i found one thermofusr 162c was cut and i replaced it and also i reset the code. it was working but after sometimes the code is appear again.......again i checked the m/c i found everything ok and i replaced thermistor also...after that i run the m/c and after some copies sc 544 is appear .again i checked all the fuse thermistor and lamp is ok......sometimes code is not appearing its working well but after few copies fusing lamp is not working if i switched on and off it s giveing massage sc 544 / some times 541

The thermostats can be reset by throwing them to the hard floor but if the code comes back you should replce both thermostats and thermistors.

I always change both thermistors with a sc541 code. It is usually the infrared centre thermistor that's at fault.

Hi mahabub, Please use the new modified middle thermistor P/N
AW100084, to avoid error from fusing unit.

There is a tech bulletin out that covers these codes and one of the things to check was to clean the Drum Potential Sensor. This would seem totally unrelated to a fuser code, but that is what it says. Something to try.

• Thermistor open
• Thermistor connector defective
• Thermistor damaged or warped
• Eusing temperature –15% less than the
standard input voltage

dear sir
i had a sc 544 in one of my machines, and when i check the sc history i find SC which relate to Drum Potential Sensor,can you please update me with more information

I had a machine that would get SC 541. I would replace the thermostats and thermistors at the same time and printer would work fine, for a while. Problem started happening more frequently and each time I would replace the TS and TH at the same time. Problem would be resolved. Well it started happening like once a week. I ended up replacing the fuser assembly cable harness on the fuser side (male) and the fuser cable harness on the machine frame side (female). I haven't seen the problem return in over 7 months.

Please check B065 4155/56 Fusing Harness. Some times there is a poor connection that makes the fusing abnormility. It happened with me 3 or 4 times and I found the same part damaged.

Flaky/dirty potential sensor will definitely throw a sc541, and it's completely unrelated to any fuser issue. Mikadonovan is right about this one-it's weird but there's nothing you can do in the fuser to fix it until you replace the pot. sensor.
