Also had fuser SC's caused by tech putting fan in the wrong way round so it blew instead of sucked!

Yeah, copiers like to be sucked, not blown.

[Coptech]

We followed all bulletins on some trouble machines. Finally tech support suggested setting 1103 1&2 to 60 seconds and 1103-3 to 120 seconds. So far that seems to be the fix. Have not had any more trouble and these machines were very bad. Especially after a weekend.

[Llama God]

As good as that may sound, I'd say that this is a temporary work-around rather than a permanent fix.

It's got to be down to either a hot roller, thermistor, thermostat or lamp and, as it's a warm-up time-out error on one of the 3 lamp fusers and you've replaced eveything else, I'd say that it's a faulty lamp or a short in the lamp cable at the rear. Try metering the lamps for continuity.

Finally, as this code is a warm-up time-out error, the 280w lamp is only used when this machine is coming out of energy save or when it is first turned on. I'd probably change this lamp for the sake of a few quid.

Our experience was that there was several machines doing the same thing. They have blamed paper for thermistors getting dirty, have changed the brackets and thermistor positions, have suggested the insufficient connector interlock. New machines will do it almost out of the box. The series I was dealing with had the quick warm up design and as mentioned, it is a warm up time-out. I personally believe it is a design flaw and as much of a "work-around" as it may sound like, it may be the best long term solution. Tech support said that Japan was aware of the problem and suggested the given setting changes as their final hurdle before escalation to field. Fortunately, the new settings have made the end users happy with their machines again.

Have had this problem before.Replace with the new thermastats in the RTB and replace the cooling fan thats near the fusing unit sometimes heaps of crap gets stuck in the fans and does not keep the tempreture consistant.

I could understand the fans causing potential SC545's but the SC542's come up on warm-up or recovery from one of the deeper energy saver states where the fuser is off. I've noticed the issue is exaggerated on a Monday morning at locations where the customer reduces the office temperature for economy. I'm with the solutions for increasing the warm-up time, turning AOF 'Off', I've also reduced fuser temperature targets by as much as 10C with no ill effect.

Has anyone substituted one of the lamps for a higher wattage from another model? Or simply using two of the high watt lamps?

Get lost, spammer

Oh I dunno, they're fighting fit in their uniforms!

The girls, obviously!

A little too young for me. I've got daughters older than that.

Careful with that - take a good look at the filaments in the lamps - some are designed to put more heat in the center or at the ends. I've hooked them up wrong once before to where the center was heating when the ends were supposed to be and vice-versa. All kinds of intermittent SC codes.

"Legal" is the only number that matters...

Guys Ive had this on a MP7500 but I noticed on the SMC report the errors were happening every day between 330am and 430am when no-one was around. We tried new complete fusers and everything then we figured it was the load of the heating system switching on during winter and just loading up the electrical system. We put a timer on the power point to turn it off at 10pm then on again at 6am and it seems to have worked.

I'm aware they are different, just curious about other lamps that may fit (and have a similar filament configuration) that are of slightly higher wattage. I haven't really looked into it and was just curious if someone out there has...
