Re: Toshiba 5506AC Whack-A-Mole
Did you try mono colors and if only black was the issue i would put a "new" black dev unit -
Re: Toshiba 5506AC Whack-A-Mole
Whatever is happening is in the black developing unit definitely.
* Check to see if the seals at the front and rear of the developing unit are leaking. If they are leaking toner replace the black developing unit, black developer, clear the appropriate counters, run black developer stir, perform the color calibration.
* If they are not leaking, make sure that the developing unit turns freely. If the unit turn with extreme difficulty replace the black developing unit, black developer, clear the appropriate counters, run black developer stir, perform the color calibration.
* If not leaking and turns easily, vacuum out the old developer from the black developing unit, replace the black developer, clear the appropriate counters, run black developer stir, perform the color calibration.
What I suspect happened is that the previous owner installed generic toner while running a large job, and it seized up all the developing units. Some of that generic toner may have remained in the hopper to contaminate the new developer.
That's my guess anyway. My compliments on your powers of observation. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: Toshiba 5506AC Whack-A-Mole
I'm not experienced on Toshiba anymore but when I was working on them we used as rule of thumb to replace whole developer unit after 3-4 developers, they just were seizing, locking up and falling apart no matter how many seals, bearings and bushings we replaced. That said I admit my opinion is only based on old Toshy machines more than decade ago but knowing Japs they would inherit design flaws as long as they can.

Re: Toshiba 5506AC Whack-A-Mole
Number three for the win!
I ended up replacing the K drum today with a new one, emptied the developer from the K unit, Filled it back up, reset all the items in the PM, and ran the image calibrations from the service menu. ALL IS GOOD! for now..
I ordered 3 more "main charge kits". They have the grid, the needle, cleaner and blade for the drum. Also ordered 3 more drums for the color. I guess they're supposed to be replaced more often than 700k+ impressions.
Thank you all for your insights! I'm back!

Re: Toshiba 5506AC Whack-A-Mole
Glad you got it figured out. Those original developer units had a nasty habit of overfilling with developer
because of a couple things. One, people don't shake the h*ll out of the toner cartridge, and more developer
flows into the developer unit than toner. Two, they had an update to the developer unit itself, to help the
flow of developer to help it exit the developer as it is suppose to. Three, The little hinge that opens, when
you slide in the wire harness for the developer unit would sometimes not open the shutter and along with
the developer not flowing properly and or the end user not shaking up the developer unit, would over fill.
The last item I came across was the first winter that this box came along. All of a sudden we were getting
developer gears chewed up along with the bearings sticking.
When I first rebuilt one, the v-ring seals, 4401949290 were torn/worn out, which was allowing the developer
past the seal, into the bearings.
Doing a little research, in the 06/08 manual, the tear down/rebuild said nothing about placing "two rice grains"
of Alvania #2 grease on the outside of the seals.
I went back, pulled the 5540 series manuals, and it said to apply the grease to the seals. I then went back to
all of the manuals, going back to the 556 series and all of them said to apply the grease to the seals.
So, since the 5540 & 08/06 developer units used the same seals, I applied the grease to the seals on every
rebuilt developer unit and in the DRY conditions we experience in the winter, the developer stopped leaking.
DUH! Kept the seals from drying out.Comment

Re: Toshiba 5506AC Whack-A-Mole
Back in my days we always added Alvania No. 2 grease P/N: 41303711000 to oil seals.
Typically one needs the following parts to rebuild properly a developer unit but the list may be too small - 6 oil seal, several gears, several bushings and maybe 2 bearings for mag roller, developer mixers, maybe mag roller itself...it was pure joy
