AF1224 fuser problems

Sounds like the wrong paper or too much heavy print area (fill). Look around the office for thicker paper and post paper spec. by the machine. Maybe someone will catch on. Have you tried going back to the manufacture for credit?

Savin gives us a discount, something like 2-3% in lieu of warranty claims.
Thanks for the input tho.

Are there any Ricoh dealers out there that are getting a discount in lieu of warranty claims?

This warranty system is widely used, and not just Ricoh.

Normally a percentage is given back to cover warranty claims. Not bad for big dealers but the little ones will suffer as their parts spend is fairly low.

It is interesting to me that altho the customer always denys that they are using special paper, it rarely happens again if they had to buy a new fuser unit.

I have a few fuser units and a couple of O/S units and spent a couple of hours this morning testing them.
The main thing I found out was that a couple of the input checks are reversed.
On the last two units that I replaced I noticed that the input checks were telling me that the oil supply unit was empty and pumping oil with SP 1930 didnt change it.
SP1930 only comes on for a split second and by the way, will show failure if any of the covers are open or the machine isnt ready.
When I installed a new OS unit into the existing fuser the oil empty bit would change.
Today I found that the bits are reversed. #23 is the oil end sensor and 0 indicates oil is at an end condition and 1 indicates that oil is in the unit. And it only takes a few mm to indicate oil is in the unit.
The other one that is wrong is the fuser exit switch. It is #22 and 0 indicates that paper is present and 1 indicates there is no paper.

So as my first paragraph indicates, I dont think the units are failing, which is what I was starting to think, but altho it is a crappy design, it is the user causing the problem.

I checked the 424 inputs are they are incorrect too.
The last bulletin I has for the B051 is #49. Is this the last one? If not can someone send me newer ones? Plus any info you might have discovered relative to this information.
Thanks, hope this helps someone.

One other thing, I havent been able to get the SP1930 to work, I tried it with an empty os unit and even hooked up a spare pump and held it in my hand when I activate the SP. I know it only come on for a split second but I should have felt something. I think I must be doing something wrong. Anybody know or ever tried this.
Maybe I should have hooked up a meter in "hold" mode.

Almost every time we have run into similar problems, it has been a result of the customer using the wrong paper.

A couple of weeks ago, we had a 1224 with rollers disintegrating -- this happened twice. They also denied using the wrong paper. Our techs were puzzled. I stopped in on a courtesy visit and discovered that on both instances they had been running inkjet photo paper through the machine right before it happened.

My point is that they might not be running paper that's too thick, but it might be the wrong type.

(Just thought I would throw my 2 cents worth.)
