I had forgotten all about this. My apologies.
As it turns off the store was limited to only so many color pages per month, by something done some odd way, as I'd done a full reset on the printer and...

The customer called us because it was receiving print jobs, cancelling them, and not printing them. Also it was printing in Monochrome only. I updated the firmware which took got it printing again,...

I could be wrong, but I want to say a blank hard drive works fine. I had a vendor send a blank hard drive for I think this model and it worked fine, but it could have been another model. I think you...

Does it feed partway and stop? if so it might be suffering from, idiots who put things into the ADF with staples.:rolleyes: The staple gets stuck in the turnaround. You can try forcing it out with a...

Thanks Lance15. I checked the things in the pdf, and ended up replacing the delivery assembly. So far I haven't heard back from the customer. One word or warning, make sure you reconnect the transfer...

Hi,
I have an HP Color Laserjet CP4525 that I'm looking at with this issue. The machine works simplex all day long just fine, but when printing duplex it will randomly lodge a sheet in the fuser and...

The repair manual shows the scanner and adf are an integrated assembly, which is not servicable. You can only replace the whole assembly which is part# CF377-60104. Depending on the price of the...

This is only their strategy with the enterprise level printers. The cheaper ones we still have to dig in and replace parts. So far I haven't had to replace a printbar, but I'm assuming it's going to...

The mech unit is the printer part of the X585Z. Once that's received I take the Scanner/ADF assembly, control panel, formatter, paper tray, and power supply off the bad mech unit, and put it on the...

I'm working on a X585Z. This model is the one with the keyboard and the single pass duplexing adf. The mech unit developed problems so we replaced the mech unit. The problem is while it detects it's...

I had a 4250 do the same thing a couple of weeks ago. It's the first time I've seen the torque limiter do that.
If that's the problem, and the customer has a broken cassette tray sitting around,...

You say you changed the rollers, but did you also change the white gear roller (RM1-0036), or just the blue rollers (RM1-0037)? The white gear roller will usually cause ghost jams, but it's worth a...

Today I installed a fuser on an M551, and I noticed there is no life count for the transfer belt. The printer has 160,000 pages on it.
I seriously doubt the transfer belt will last the life of the...

I put the new finisher in today, and the printer is working fine. If I had to guess, there was probably something wrong with the board in the finisher.

Just an update. I went out today with the new firmware and it didn't fix it. I was able to borrow a finisher from another CM4730 and it turns out it's just something wrong with the finisher.
I did...

Today is apparently weird problem day. I was working on a HP CM4730FSK today and it has an odd problem.
It'll work fine on all things but one, when it's told to staple something, it'll staple it,...

It's possible there is some paper stuck somewhere in the path somewhere that it's only intermittently causing problems.
You can unscrew the registration assemby, lift it up some, blow some air in...

This is what I get for reading in a hurry. My apologies and I'm glad you were able to fix it.

One thing I've ran into on the 4700's is if the table is too small, the printer won't sit properly and apply pressure to the tray, preventing proper lift.
Is the table bigger than the printer or...

I've been lucky enough to have not needed to replace one yet. They made the swing plate gears much thicker in these series and beyond, but it still does happen. There's instructions out there for...

Thanks to everyone for their input. I'm scheduled to look at the printer on Monday and this gives me a few ideas of some things to check.
Thank you.

It's not the solenoid sticking, that was one of the first things I checked, hoping that was the problem. That solenoid has been the source of a lot of my 4250 service calls though.
Thanks for the...

The service manual suggests starting a printhead replacement. In theory you'll start the printhead replacement, open the door, close the door and it should start the maintenance cartridge replacement...

I don't know if this is your issue or not, but there is a scanner controller PCA that sits behind the scanner assembly. I've had this board cause problems on occasion. If that doesn't do it, your...

I got to work on an interesting printer today, a dual tray P4515 printer with a very specific and very odd jam.

When tray 1 or tray 3 is used no jams, runs just fine.

When tray 2 is used it...
