cp3525 with 59.f0 error

Re: cp3525 with 59.f0 error

I replaced the whole assembly.

Here's another head scratcher. Had a 59.F0 on a 4525. Removed the ITB and carts and manually rotated the ITB drive coupler (that you can see on the fuser drive assembly) and the error went away and hasn't returned. Has been about two months. Go figure.

Can't seem to find the part number for Primary transfer roller disengagement solenoid.
Can someone supply it?

Re: cp3525 with 59.f0 error

Hello,

My Laserjet CP3525 displayed the 59.F0 error a few weeks back. After googling I found this thread and while not a professional printer tech, I gave it a go. As soon as I got the solenoid out, I knew it wasn't the problem. It did not stick when tested but I went ahead and removed the pad and applied a replacement. The good news is I got the printer back together. Bad news is I still have the error. Very clear grinding noise when the printer goes through initialization.

YouTube

Apologies for the poor video in the beginning, wanted to ensure the grinding noise was picked up by my phone. Any suggestions as to what the issue is? Transfer belt turns when I move the big gear and something inside does it's thing when I move the small white thing but unsure how to further test. Transfer belts aren't cheap enough to buy to see if that fixes the error.

I have about 12 toners for this printer so I was hoping to fix it. Printer has less than 25k total pages printed on it. Drive unit repair looks to be outside my skillset due to alignment and the recommendation to follow the service guide exactly which is something I do not have access to. I figured I'd post here and get an opinion before I recycle the printer.

Thanks.

yu really need to focus on the display for us.. make sure you turn off lights ( enough on display)

the thumping is from toners itb belt moving up n down during init

the gear grind/skip sounds like feed/fuser

how long since maintenance cycle performed?
total pages on unit?
Genuine OEM Supplies?
have you messed with anything other than ITB?
did you clean the plate and frame of solenoid ?


so many questions so little info

Thanks for your reply.

Here's a video of the display. It's hard to capture well but nothing notable outside the error. YouTube

The thumping sound always happened. It's the buzzing sound that is new if I recall. I didn't power cycle this often, it usually was left on in standby.
Maintenance cycle? Never that I am aware of. I've had it a year.
4k black, 18k color
yes, genuine supplies that I have a stack of :/
I took out cyan toner, and did the test earlier in the thread to see if the white gear turns. It does.
I pulled the item above the ITB out and reseated it.
Yes, I cleaned both the plate and frame of the solenoid.

Forget about the solenoid and replace the whole fuser drive assembly. There could be any number of things in there causing it. And they're not all that expensive.

This blog suggests replacing it is likely outside the ability of amateur repair. HP CP3525 - 59.F0 Part 2

The big part of the job is taking off (and realigning) the main drive assembly. HUGE headache.

I haven't found anything that explains what that process it. The only (English) video I found was the one I used to take it apart to replace the solenoid.

I wish I had a spare transfer belt to swap in to rule that out. Any suggestions on testing the TB? If I turn the big gear, the belt moves. If I turn the little white thing, some stuff happens inside but unsure what is supposed to happen.

Re: cp3525 with 59.f0 error

Everything needed by a professional tech is in the service manual, including how to re-time the main drive.


If your not a professional tech, do not attempt. It's not an amateur job.

ditto that

If you can't find it in the manual, you shouldn't do it.

Re: cp3525 with 59.f0 error

It's actually not THAT big of a deal. Aligning the gears is explained in the manual. The bigger headache is wiggling the main drive into place again without losing the timing you just set.

Re: cp3525 with 59.f0 error

Thanks for the replies. It looks like this unit is destined to the recycler.

Re: cp3525 with 59.f0 error

Update: I fixed it.

thanks for the guidance.

Re: cp3525 with 59.f0 error

What was the fix?

Re: cp3525 with 59.f0 error

Wow.

I had ordered one of these 'refurbed' from a company, and the solenoid on it had not been touched. Not repadded or replaced or anything.
