Have you done anything to fault find?

If you haven't already, I would start with swapping the Magenta drum with the Cyan to see if the fault transfers.

Good Luck.

Did you update the firmware ?.

Re: TaskAlpha 3550ci Strange Magenta Lines

Did you update the firmware or in fact do the full firmware install, not the turbo mode. ?.

Alex he posted the above. LSU are the laser unit. acronym for LSU [ Laser Scanning Unit ]

I am fully aware if what it meant it just passed me that's all, was stroll to fast, but he says he change the magenta LSU doesn't these LSU comes in pairs? Like the other color units. He needs to change all 4 developer units and drum units. Or check the other developer units spacer of they are damaged, an issue like this happen to me on the TA2551CI and i wad getting magenta lines, I had to change the cyan developer unit to correct the issue. It was an arcing problem

It sort of looks like somebody scraped a label off of the primary transfer belt, and only used a scraping tool of some sort. If that person had used an orange oil based solvent or paraffin lamp oil and a soft cotton pad, there would be no scrape marks or scratches. All you do is follow up either of these cleaners with an alcohol wash. Then it takes about 100 images for the primary transfer cleaning blade to squeegee off the remaining solvent.

I think it's probably too late to save this belt, but I suppose all it will cost you is 30 minutes of cleaning to find out if it can be saved. =^..^=

bingo at least one person is on the right track i cant believe the comments here. This is a common problem seen everyday on these machines

Delt with these machines everyday since it came out. never seen one.

If its laser glass thats dirty, the line is white and I think the line goes horizontal.

As to the mirror, this is a "internal print", mirrors aren't used. Laser mirror are sealed from factory, unless it has been tampered you wont find spec of dust in there. If its laser mirror faulty you wont get lines, you get scattered beam resulting in weird patterns.

There seem to be writings behind the the sample, so I have one recommendation.



provide a clean sample next time.

Could not have said it better myself. The printout is the colour belt sample, so no mirrors to deal with there, unless as others were referring to thetop of the LSU glass, and in that case as the above mentioned you would get voids. That issues for whatever reason will only come from the dev/drum unit as it is on one colour only, or worst case the drive assy that drives the magenta unit

Being a 3550 would indicate its at least a few years old. We are seeing a lot of these in the field and on refurbishment where the mirrors inside the laser have become dusted. Even the polygonal mirrors show dust towards the end of each segment. Thankfully they are relatively easy to get the top off and clean. Flip it over and remove the polygonal motor and clean the mirror while your at it. Needless to say use good quality lens cloth. Sometimes the "dust" looks more like a smoke haze. Will really depend on the environment the machine has been in. Amazing the difference it can make to a refurb.
