Ricoh 5560 - Vibration lines

[AHobden]

Hi, first message here so hopefully someone can help.

We have a Ricoh 5560 with a Fiery E-7000. Currently experiencing vertical vibration lines (dark/light/dark/light etc) about 2mm wide, worse towards the trailing edge of the page. Our tech has replaced all dev units/front bearings/image transfer roller/transfer belt/fuser rollers and several other things but the problem reappears after a couple of months running. Any ideas what else can cause this? The tech has done well but I think this is baffling him! Current reading on the machine is 116k colour 600k b/w. Approx 2.5 years old.

try checking if its the lubricant bars of the drum units and lubricant bar transfer brush roller there are new part numbers for these bars, ware out to fast.
some SP to do after changing the L.bars see service manual

Hi, wow what a quick response! good work! I talked to the tech, apparently he looked at them and they were only half worn. All the PCU's were changed a couple of months ago so he is assuming he was supplied with the new part no's but he is going to check it out. He's getting a new transfer roller assembly and will check out the lube bars at the same time tomorrow. Any other thoughts??

difficult to say without seen a copy, try changing the brushes too, I´ve got one with a scratch maid by me on transfer belt works no problem, quite a machine runs smoothly only one problem color registration sub scan is not to good, but now we have the MP c6000 all faults corrected.
just recalled the new lubs are higher, because the spring tension is to soft ,please just dont try giving them more tension just add bars OK, 3 am in europe gonna have a nap hehe, have a nice day, you welcome

I'll pass this on to the tech. We will be "upgrading" to the MP C6000 soon so good to know all the problems are fixed! Meanwhile this needs fixing on this machine, I'll keep you posted with results.

Have had the tech rebuild the paper transfer unit (all associated parts) and still no change. Attached is a image of the problem, this is a section of an image on the page (160gsm) print. (upon doing a full A3 size solid colour blue, the lines show all accross the page). Any further ideas??

Any day now?

There are so many tech and mod bulletins for this model it's not even funny.

A lot of problems are fixed by simply updating the machines firmware and applying the latest Fiery controller patches.
So that's a good place to start making sure everything software wise is up to date.

Looking at your sample and what you have said.

• Thick paper 160gm
• Full coverage
• Vertical lines roughly 2mm apart

The attached RTB is a close match.

the sample is difficult to tell, íf we could see a C-4 chart single color cyan\magenta\yellow\blk\ and full color we could go into other directions, this machine is so complex that it can be so many things.
I personaly dont think its the fuser pawls that are causing this problem, I´ve seen copies where the pawls were causing the problem and it totally different, much more apart, but I would check the belt.
doesn´t seam to be the gears no MB. because the unstable image (lines) are not horizontal to the exit of the page, I think they vertical and that takes me back to the dev. units LUB. bars but then I repeat my self only seeing single color copy can try helping, DaZ had a great Idea, update firmware, fiery patches only if necessary. one thing at a time first solve coping problem and then printing. just another thing: check optics lamp, also try stoping a copy in the middle of process and see if the problem is already on the Drum.
