IM 9000 Fusing issue

[Old Crow]

I had the exact same issue a couple weeks ago. Poor fusing. BUT the machine eventually threw a SC547 code. The FU1 on the PSU was blown. I have had many situations like this, and replacing the fuse has fixed my issue. I ordered them on Amazon. Bojack 5x22mm 8A-250V. I hope this helps.

Thanks for this information Ajester. It sounds like it would be something weird like that. Going back next week to change developer and toner but will look into this before doing all that. Will let all involved know what happens...hopefully something good. BTW, we tried another fuser unit but no help.

i hope that this can be of help for you. (this is for im9000)

Yes, thanks!

Yes, thanks!

so?...is there any news?

Thanks for checking in, sorry for long delay, this kind of fell down the ladder of priorities. The fuse on the psb was OK, went through the fuser again and all ckecks out well; lamps, bearing positions, camming together properly, etc.

Early on, when checking what the power requirements were, the original service manual, version 1.00 (Oct. 2020) stated 120V 20A. It does not distinguish between the IM6000/7000/9000. This seemed odd given that previous the 90ppm machines used 220V. But...the machine (off lease) came with a 115V/20A power cord so that's what we went with.

We recently got an updated version of the manual (1.04, June 24), and under Revision History/power requirements, it states 120V 20A for IM7000/8000 and 208-240V for the IM9000.
So, we now believe we were plugging a 220V machine into a 115V line and are hoping/assuming this was the problem all along. We also assumed that if it did require 220 and was only getting 115, that it wouldn't work at all or would throw a service code.

So we think that due to our ignorance, an incorrect manual and incorrect cord, we have been chasing our tail for a long time. We are waiting on a 220V/20A cord from the vendor (they are not hard wired on this machine).

Even though it says 220V in the revised manual, I'm still leary of frying boards if it's not correct! Can anyone out there confirm that 220V is correct? Thanks

The only thing that would get fired is the power supply and any 120 lamps in the fusing unit.

What does it indicate on the label on the back of the machine? It is possible that the very earliest IM9000s were 120. If that is the case, you may also need an updated power supply and cord connector on the back of the 9000. Normally a 120 power cord cannot be connected to a 220 model.

Also check the insulators on the ends of the lamps. They should have the voltage they require printed on them.

Many years ago we had a customer with a 40 ppm machine, pre Martini, that was actually a 40 ppm printer with frame assembly that it rolled under and a scanner on top of the frame. Kept throwing fusing unit errors on jobs longer than about 10 pages. The tech trained on the 40 to 60 was having trouble so our boss had me go take a look, back then I was primarily dictation and network. First thing that I noticed was the leads on one of the fusing lamps were a different color than the service manual indicated for a 120 volt model. Checking the insulators, the voltage and part number were for the 220 EU model. Ordered and installed the correct lamp and no more problem.

One other thing I ran into in the past was the connector. The locking tab on the common lead to the connector for the lamps had broken off. Static testing continuity with a meter with the fuding unit out of the machine and the lamps looked good. Voltages at the machine side of the connector were all good. Still the lamps did not come on. Then I notice tha one of the leads moved back a little when I was testing continuity. Grab a hex key and was able to push the lead back almost all the way out. The individual lead was not available through so we had to replace the entire connector block.

Thanks for the input slimslob, forgot to mention we checked the label and it does indicate 220V. Also, for what it's worth, the brochure also states 220 for the 9000.
Will also double check the lamp voltages.
Will let all know what happens when we plug it into 220...hopefully no smoke
Haven't had one flame up for some time now.

I understand, I have never tried, I always thought that by connecting a device designed for 220v to 110v it would not even turn on, so since it seemed to work, look at the temperature sp on the display, it should have shown a lower target in teory(?)

Yes agree, that is one thing that doesn't make sense; we checked the temp through the SP early on and it indicated that it was correct.

I wonder if someone may have put the lamps for a 7000 in it because the customer wanted 90 ppm machine but didn't have 220 service and didn't want to pay to have it put in. Requires a lot of changes to go to including the power company may have to install a different transformer.

That's something to consider...stranger things have happened. Still waiting on the correct cord, should be going back next week. Will post the results then.

UPDATE: it WAS the wrong (voltage) cord. It needed 220V ...copyboy99 called it early on but we were under the assumption that it required 115V and the cord we received with the machine was 120V/20A, so off we went in all the wrong directions.

Two things that threw us off were the incorrect info in the original service manual stating it required 120V, and the temp. readout in service mode was correct. I'm guessing that was because we were watching the readout while the copier was idle but when making multiple copies, it drew the temp down enough to cause fusing problems but not enough to throw a code. Also, no other odd issues due to having only half the power requirements. If we had thought to simply look at the label where the cord plugs into the copier early on instead of late in the game then we probably would have saved a lot of time. Live and learn(hopefully).

This was a classic case of KISS(keep it simple stupid!)...which is how we feel, but happy the %$#! thing is working. A few lessons learned, one of which is don't trust TFM!

Thanks to all for your great input and time. Maybe someone can save some time down the road from our mistake.
