SPC messgae on C6530

Re: SPC messgae on C6530

All great questions and more suggestions of things to look into.
I was very cautious about reinstalling the belt so as not to screw up a $350.00 part I saw the pin on the back side near the black drum, I looked for the mount on the yellow side but did not see any type of aligning pin I will look again. Book does not show how to set it back in.
I am looking at the sample yellow and I don't see the bend possible it happened when I scanned in the sample. I looked back and it does looked scewed in the scan sample but the original is straight.
I did not know you could swap drums , they have a color coded dot so I thought they were specific to the slot they are in.
Can I swap drum potential sensors as well ?
The unit prints a very nice counter page , with a very little shadow. so I guess that's an internal print.
I did not pick up on the fact that there was no black patch on the K page , that is an interesting observation. is it suppose to ?
Again this goes to my ignorance on what the unit is suppose to do.

Does the transfer cleaning blade float a little ? Is that normal ?

Yes you can swap drum assemblies. There will be a small amount of cross contamination of toner colors, but nothing that won't work itself out with use. Also pay attention to the drum waste shutter(s). They are easily damaged.

Yes. I recommend that you try it. You'll have to do a little more disassembly of the front of the imaging drawer to get to the wiring. The toner hopper assembly comes out as one big awkward, messy piece. 4 connectors, and a dozen or so black plastic snaps. Start at the yellow end, and work your way around. It fits tightly, so you'll have to do some struggling and subtle prying. Watch for changes in your error codes (was black, now cyan...).

Yes it's supposed to have a black patch, and that's what concerns me the most. If it's able to maintain color calibration, and print black text, but cannot make a black toner density patch (and consequently cannot maintain toner density), that tells me that the System board is not telling the laser to write that patch.

The SYS board is a difficult board to install. On most Toshiba machines the machine's "identity data" is stored in three locations: on the SYS board, on the LGC board, and on the SRAM. The machine can recover if the data is different at only one of the three locations. The machine cannot recover is that data is different in all three locations. There are several pages of instructions on how to export and import data. You want to read that part of the manual closely before starting. And have the latest firmware available.

Maybe I'm overreacting here. How did you get these prints? I'm assuming that you removed the primary transfer belt cleaner unit temporarily. If that's the case, maybe the LTR paper just missed the patch on the belt (belt = 60", paper = 8 1/2"). If there really was no patch you would have add toner and toner density issues, and you haven't said anything about that yet.

Yes it's normal for the primary transfer cleaning unit to fit loosely when the belt is outside the machine. There are leaf springs on the main frame that apply pressure to the primary transfer cleaning unit as it's inserted into the machine. Even then, there is not a lot of pressure. As long as you aren't getting in brown anomalies on you images (the color of primary transfer waste), don't worry about it.

I'm glad that that yellow patch is not bent. I can see how that might have happened in scanning. One less thing to worry about. =^..^=
