A little late on this but --

I've seen plenty of times where every now and then a dev unit puffs a little bit of toner out on 2550ci and 205/255c . Haven't noticed it on the new models yet, but when this happens I educate the customers to shake their toner before putting it in, then go to the dev unit(s) having trouble, tap it with a bit of force all along the top to loosen up the toner or foreign object and vacuum. Don't tend to get call backs after doing it. Then again, I always update firmware so that may be the solution as previously suggested.

This has become a common issue, many dealers are having this problem with toner smudge/dropping. I think it's actually more common than reported, most customers probably just live with it. The customers who can't accept this are however very psst off. No real fix at this moment???

We have a customer with a 255c and they had a big vertical yellow streak down their prints and copies.
I noticed the "quality" design of the door "flaps" that these models use to keep the DV/Drum units in place/covered... It seems the secondary flap behind the main one comes undone, allowing what apparently is a dislodging of the Y DV unit.
There was yellow toner *everywhere* inside this stinkin' thing, and re-securing the secondary flap (no easy task on this one) made the streak go away.
I really dislike the way Kyo decided to implement this door flap design, it can create big issues like this. hint hint, Kyocera

Having to go back every week now for this 255c issue
What's going on here?????
Boss said to check drums so that they are seated all the way but there's no image issues,
just the toner droppage and it's only Yellow.

Re: Taskalfa 2551ci dropping toner

Both the TASKalfa 2550ci and 2551ci has toner dropping issues. There is a new bulletin on the 2551ci announcing a "new" developer to resolve the issue.

Seems like this problem is going to stay with us for a while, firmware cant fix it.

We have a 2550ci dropping toner we replaced all of the dev units twice for the issue but I am the only having the issue, at least that is what Kyocera told me.

If your getting colour streaks down the page there is a bulletin for a change of gear on the charge roller to stop vibration

Hilarious... - then ask them to take back your "monday" machine and replace it with a TASKalfa 3051ci for your troubles.

Re: Taskalfa 2551ci dropping toner

If you take the charge roller assembly out, it will give you access to the three screws to take out the cleaning blade. Remove the cleaning blade and vacuum the auger. Make sure there's no labels or something strange stuck on the cleaning blade or in the auger. I have a setting powder bag, so when its clean, I like to wipe the cleaning blade with the setting powder bag, and apply some to the drum before putting the cleaning blade back on. Manually rotate the drum to remove setting powder before putting the charge roller assembly back on. Probably should also blow off the charge roller or clean it if necessary to get that toner off. I find cleaning it with simple green works wonders, just have to make sure to get every little speck of lint off after cleaning it.


If that doesn't work then probably just need a new drum. It looks to me like the cleaning blade isn't doing it's job.

The drums are interchangeable between all colors (even though they're labeled) so if you need proof to justify replacing the drum, just swap the yellow with cyan and watch the problem move. from the picture provided, it seem that it may not start dropping toner right away, but you should definitely be able to see the lines right away if not either on the copies or on the drum itself.

I am having the same problem with a utax but no bulletin about dev units does anyone have kyocera one thanks

Re: Taskalfa 2551ci dropping toner

The "common" issue of just dropping blotches of toner onto the page is not caused by the drum/blade, it's actually caused by the developer. That is why they have updated the developers. If you turn the developer manually you will actually see toner collection on the mag roller.

We have had the drum marked down centre couple of inches utax partner site has no mention of dev unit problems in their bulletins but were having ITU problems dropping toner
