I just took out the entire itb cleaning unit and completely cleaned it, i used a blower because i saw a lot of waster toner on the inside, on your recommendation i lubricated the cam mechanism because i was feeling a little stiffness, i turned it several times and sprayed a little wd40 be the bearing areas. I re installed everthing and tried a couple of prints, as the attachment shows there has been a 100% improvement in the print, the trailing edge fade has gone completely, the skid marks has reduced, hovever i am sure that the itb cleaning blade has to be replaced since i realize it is worn. Evidence of this shows a buildup of excess toner above the blade where the skid area is as if the blade is not completely cleaning the transfer belt, I am still gong to change the lubricant bar & brush, blade as well as the corona wire just as a preventative measure, as well as the entrance seal in the cleaning unit, Thanks to everyone for their assistance.

I have had this since the AC3006 came out. If the fading is at the front of the print, then I found that it had something to do with the drum rails. Seesm that with time the drum sloutches at the front a bit lower then the back. Nothing one can see with but I experimented raising the drum from the frontwith shims, raising the dev unit from the side pvc tape under, and even raising the charge wire at the front to try to get more charege. All these experimints were carried out after replacing drum and devs. All gave a slightly better result but not a complete cure.

Hey Guys,
Ihave a new problem. anytime i print on extra thick mode or thick mode i get a washed out copy, the same thing happens in the copy mode, however if i make prints on plain paper the prints comes out fine. the problem is only happening in the thick & extra thick mode. the attached print is a calibration sheet in extra thick mode.

Did you do the autocolor calibration for the fiery with Kodak pantone, maybe that can help

I'm reading this from my Blackberry so its hard to see the sample clearly, but it looks like the leading edge in the center is extra weak then offsetting onto the trailing edge - if that's the case the fuser needs a PM.

Damp paper is also famous for faded images in high humidity areas like mine - try a fresh sealed ream.

The general image looks more like PTR clutch or maybe PTR bias. If you just WD40'd the clutch that's gonna be the problem. I don't replace them anymore unless the hubs are totally shot because the new ones used to need the same disassembly / clean the dried grease / lube with a good grease / reassemble treatment that you had to do on an old one.

The line speed difference in thick modes is enough to cause a stiff clutch to fail, but eventually it would show up on normal paper.

Where is the PTB clutch? does this refer to the Paper transfer belt clutch?

[Shadow1]

You have to pull the back of the machine off and swing the Fiery Controller out of the way. There are 2 identical wrap spring clutches in the main drive just below the drum drive. One of the clutches is also behind the flywheel and a piece of the frame that will have to come off to get the flywheel. One is for the cam that moves the ITB cleaning assembly, the other is for the Paper Transfer Roller cam. Both clutches fail, so you might as well clean and regrease both of them while your back there.

If the PTR clutch sticks with the cam engaged you get Magenta copies or Black prints with very little of the other colors because the PTR transfers nearly all the toner off the ITB between developments except for the last one. For some reason the machine lays down the colors in a different order depending on if you are printing or copying with black being last for print and magenta last for copy.

If the PTR sticks disengaged you will get very weak copies (like in your example) because the paper is not pressed against the ITB during transfer - its amazing to get anything at all, but paper rubs the belt just because its pointed that direction coming out of the aligning rollers.

Same deal with the ITB cleaning clutch - it either cleans all but the last color from the belt or never cleans it at all.

Note that both clutches can cause Magenta / Black only pages, but the PTR clutch usually leaves traces of other colors, where the ITB cleaning does not since its designed to scrub the image belt totally clean.

See Tech bulletins 51, 53, and 54r (U.S. - not sure about E.U. bulletin numbers)

Did you use tick paper 2 from the drivers

Isnt this something to do with the second transfer roller? It has been at least 5 years since i worked on these heaps of junk so i could be wrong!

[Shadow1]

...on these heaps of junk...

Anybody who had to work on a Lanier 5606 will take issue with that!! Fortunately I was spared most of the 5603's.

These were great machines at the time, and I still think they make a better image for some jobs. They are very labor intensive to PM for the number of clicks they run, but so was the 1224c for different reasons.

[copytechman]

Goodness! Don't remind me of those machines (5603/2003) ArrrrrghhhH!!!

A!

I think there is a problem with paper transfer roller bias.Check SP2-310-2 to SP2-310-29 and adjust the PTR bias for the type of paper, and check the image transfer belt bias.( SP-2-301)

Does anyone have instructions on how to disassemble the back of the machine to get at the clutches, I have no instructions for doing so and would clean/grease same.

Stinger anti tank missle works wonders
