59.F0 Error

[downunder3]

Hi,

after I moved my printer t a different room, the printer quite often shows a 59.F0 error. On many, but not all occasions the is a clicking/rattling sound at the end of the initialisation. I have checked the ITB which appears to rotate ok. I also did the sensor check, which was also ok. 

Now I need help figuring out what the problem is and whether it is worthwhile to repair the printer or buy a new one, if repair would be too costly.

After everything I have read in other posts it could be the fuser drive assembly, but I can only share my laymen's opinion, as I am no printer technician. Maybe important to note:  (1) I carried the printer around, before the error occurred the first time (maybe a mechanical issue?). (2) The error does not always occur. Sometimes I can print 50 pages from several documents before the error occurs. Sometimes I can't print at all. 

In addition, I noticed that there is a lot of waste toner once I print. The toner collection unit was (too) full and I replaced it and cleaned everything. But also after replacing & cleaning it, the toner waste seems to remain trapped in the top piece of the ITB, rhather than being moved to the collection unit. Maybe it was clogged and now does not work anymore, even after those changes? Can this have anything to do with the 59.F0 error or is this a separate problem? Does that mean I have to replace the ITB too?

Would be great, if anyone can point me in the right direction and ideally also give me an idea on cost to fix this (cost of parts and technician time).

Thanks so much in advance!!

It's a solenoid which controls transfer belt got sticky so 59.F0 appeared.

All you have to do is trying to get to the solenoid and solve the sticky problem then 59.C0 will be gone.

It's a big job to get to the solenoid if you want to do it formally but there's an easy way to solve the problem, you just find out an easy way to get to the solenoid only if you can see where it is then you can try to solve the problem without having to take everything apart. 

What my experience is to try to take the top cover off then you can "see" the solenoid seated there.

Before top cover taken off you need to deal with back cover and left cover and the right most cover of right cover.

It'd better go google a Service Manual and check the following link.

It is likely the sticking solenoid that you have probably found reference to. The solenoid can be accessed and repaired without taking apart the entire drivetrain however you do need to remove most of the electronics.

Thanks a lot for the suggestions, I will try this.

But will this also sort out the waste toner problem? I just had to print around 40 pages and for the first time, the waste toner most have dropped onto belt, as it there are grey dots and stripes on a few of the pages.

Toner evacuation has always been an issue with this design. You can try removing the transfer belt, holding the shutter on the waste bin open and shake the belt over a garbage can to remove excess waste toner. Do not touch the belt with bare hands, wear gloves and handle by the edges.

Thanks a lot for the quick reply again. It fills up really quickly. I had cleaned it, and after 50 pages it is a real mess. I didn't have that issue before. Could the transfer belt not work anymore properly all of a sudden or can that have a different reason? I have used the printer for years with no problem at all...

Sorry for me to keep asking questions, but this is really really helpful for me: I noticed that on the top end of the transfer belt large parts of the rubber foam had crumbled away - I assume that this rubber foam plays a big role in removing waste toner from the turning transfer belt - am I right? Could it be that the reason for the toner dust on the transfer belt is, because most of that small stripe of rubber foam isn't there anymore? I noticed that large pieces fell off when I took the transfer belt out (probably got old over the years). 

If this could be the reason for my sudden waste toner problem, please let me know. And please let me know, whether I can order a small piece of that rubber foam somewhere. I wouldn't want to replace the whole transfer belt because of a tiny stripe of rubber foam that costs next to nothing (when you know where to get it). 

thanks soooo much for your helpful answers!
