You might want to take a look at the existing doc on pinch rollers as it provides a great set of instructions on replacing them along with images.

OK Sorry, I read that like you thought I didn't know about the instructions already.

Do me a credit favor and add a link to my website by the pictures and PDF if you are going to use them on your wiki please.
Thanks

No problem. BTW, its not my wiki. I'm just one of the contributors. The point of the wiki is to share what we learn about the Z3100 printers.

That's fine if it's you own info you are sharing. Taking my info and posting it without permission or credit isn't cool.

Thank you for the credit line, that's fine.

Tech just called, said he will be here within 2 hours!

kaelaria · « **Reply #104 on:** February 14, 2008, 02:35:00 pm »

Oh and what a shock - more broken promises.

First a call when he was supposed to be here saying he's 2 hours behind. Now a 2nd call to say he won't be here until tomorrow.

Batting a thousand, HP.

What kind of test could we do to know if the machine is prone to mark paper with these rollers ?
To avoid ruining a print or a piece of roll, is a test possible with a single sheet ?

Just make a white image and print it.

Did you order and receive your free rolls from HP Startright page ?

kaelaria · « **Reply #108 on:** February 14, 2008, 07:41:47 pm »

I don't even know what that is...

kaelaria · « **Reply #109 on:** February 14, 2008, 08:00:52 pm »

Googling it, I see it offered in other countries, but I don't find it for the US.

First I want to give a "hats off" to Ben Wolf @ HP. He has taken the communications problems within HP U.S. very seriously. He replied quickly and he seems to know how to get things done.

Second I would like to complement Brian, my field tech. He has been patient, he listened and actually looked at the problem. He discussed on site with me about our respective observations and what the problem might be. He explained to the U.S. hp office folks that I was being very patient but that I had been offline for too long. He consulted this thread to read up on the problems when I gave him the URL.

There was a shipping error for the parts and Andie at HP took care of it immediately and profusely apologized and then made it right.

my parts have been delivered on wed.

I anticipate having my printer on line shortly

When I started this new thread as a follow up to those threads started earlier by others I didn't expect it to last this long.

http://z3100users.wikispaces.com/ is also compiling an excellent one stop shop for information on the z3100 and related information.

Lastly I think a huge thanks should go to Michael Reichmann aka Luminous Landscape for providing an excellent venue for discussion and reference.

UPDATE!

I am VERY happy to say that after 3 hours of two techs doing the upgrades, it now prints BEAUTIFULLY!

The package that the tech had to have shipped turned out to be a new installation tool for the pinch roller assemblies. Neither tech had done the swap before, and HP did not provide them with any instructions on how to use the tool - but they were very much on the ball and figured it out. They both agreed that this is definitely a two person job for proper reassembly, and would hate to attempt it alone lol!

The printer was stripped almost bare, down to the core frame.

The new starwheel assembly is virtually identical, and none of us could detect any huge difference other than the addition of two black plastic parts on either side. We have no idea what they are for, but there are NO star wheel marks anywhere on the test print that just came out - on low quality no less!

The new roller assemblies also are perfect, not a hint of lines or smudge anywhere, just as it should be.

They showed up on time at 9 as promised yesterday. It was pure luck that he had a helper - the new guy was in training. I thought it comical that even they had to sit on hold for 30 min with different HP people for support. By the time they got through to someone that knew, they had already figured out how to use the tool themselves!

The black plastic parts on the ends of the star-wheel assembly can be pulled out manually which raises the assembly another couple of mm for worst case scenarios when some paper/ink combos might still produce star-wheel marks.

I also agree that Ben has taken these issues seriously and we have been communicating as well.

This morning he let me know that one common issue with the roller marks has been the Harman Gloss FB Al paper which is the paper I reported problems with, even with the new rollers.

Ben says that they are currently testing this paper and looking into the paper/ink settings to see what they've missed. Hopefully HP will be able to figure this one out and eliminate my last issue with this printer.

Jim-
Hare you had any indication from HP about what the replacement policy will be with both new designs? I'm wondering if these will eventually be swapped out for everybody, or if the will try to qualify people before agreeing to swap the parts for the new design as they are doing now. I certainly understand the prioritization while this is a new process with limited parts, but would love to hear that they plan on doing this across the board with everybody eventually. It seems like excellent PR if they do it right. Their early track record with this did not help their cause with their client base and could probably be described as "not right".

OK I'm done proclaiming victory, it keeps coming back and biting me in the groin.

So I switch out the Ilford for the HP ID Gloss, and find this on every freaking print now.

What the heck is going on? It's almost like the heads are dripping or something.

And thanks for the info on the side parts - they are indeed manual shims. You have to lift the assembly and then you can pull them out to raise it slightly.

This looks like head strike, but I am printing on low res, the correct paper is selected and nothing has changed other than the new parts.

It's even splashing back on the new rollers and the paper before it even gets to the heads!

I tried the built in head cleaning - no effect. I'm calling HP right now to get the tech back out.

Sigh.

Oh one other thing - can someone look and see if thier rollers are staggered like mine are now? I don't remember if they were or not before.

Jim Cole · « **Reply #117 on:** February 15, 2008, 03:26:20 pm »

Hi Ron,

I have been told by HP that the new rollers and the new star-wheel assembly are in beta testing and therefore in limited supply. They want to see if they can solve all the issues on a few printers before they roll out the parts in enough supply for everyone. This makes sense as it would cost a fortune to send techs out to all owners on the first go around only to have the new parts not measure up and have to do it all over again. I'm sure when they decide that they have the problem licked, the parts will be available to everyone with issues. HP has been very progressive in their support of Z3100 owners.

My pinch roller assemblies are NOT staggered like that. There is a slight visible variation, but nothing like your photo shows.

Sorry about the trouble you are having. The only reason that my tech had to remove a portion of the rear side of the printer was because a spring popped off one of the roller assemblies and he had to get inside the back to get to it. If not for the spring, he would have completed the install of the rollers and the star-wheel assembly from the top of the printer. Not sure why your techs had to disassemble the entire printer.

That's something I was wondering about too.

The instructions that came with my parts showed popping out the rollers with the shafts and leaving everything intact.

His new tool and new instructions call for disassembly and replacement of the entire pincher assemblies as well.

It looks like they were not installed correctly to me, being twisted - like they twisted as the screw was tightened - the tool may not have been used correctly afterall, it was to align them during installation.
