DP-8035 getting "burned" speckles on drum

[Urushiol]

Unfortunately we have used non-OEM toner excessively in our panasonics. Everything from DP-135's to DP-8060's. AFAIK all the non-oem we use comes from Polek & Polek.

Here is a pic of the toner bottle, with no identifying marks of course

I gotta case of 8060 OEM on the way to try out.

Just an FYI if you ONLY replace the toner with OEM, it might not fix the issue, since the dev unit will have a mixture of the old toner in it.

Installed oem toner, oem developer(r), oem drum(r), oem blade in one of the dp-8060s today, I vacuumed the dev. unit out thoroughly, and also purged the toner hopper. Will report status on machine in 2-3 weeks.

Thats the part I hate the most on aftermarket components. The owners / sales people of my company think that aftermarket is the way to go because its so cheap, but they don't take into consideration tech time / parts cost / customer unhappiness into everything. I know for a fact that Panasonic intentionally makes their machines non aftermarket friendly. As does a few other major companies. The best thing to do is to stick with OEM components, the only aftermarket part I put in any Pana machine is the fuser heat roller / pressure rollers, and thats only because they don't have any effect on copy quality (unless stupid end users decide to gouge them with scissors / letter openers / pliers)

But if you have customers with old analog machines and the sales people can't seem to get them to upgrade.... Install aftermarket drum / dcb / dev / toner. In 1 month it will cause so many problems for the customer they will want a new machine.

Yep.....p&p is one of the most failure-prone brands of toner out there in my experience. However, even the 'good' compatibles WILL fail maybe 1 out of 25.....and when it does, it takes out lots of expen$$$ive supplies with it!
In stark contrast, in the 22 years I've been doing this I've seen 1/100th as many problems caused by OEM's supplies, and usually those could be tracked down to poor storage/handling issues, i.e. unsealing a bottle of iron-ferrite based developer, and leaving it on a damp cold shelf with the cap half-screwed on. May as well have thrown it into the garbage!!

Yeah, with a bit of reflection on the subject, I recall 6 months or so ago we had a slew on 1520/1820s with an odd brown buildup on the fuser rollers, there was no hope cleaning it off, just had to replace them, I was just about to request that we try a different toner when the problem abruptly stop surfacing. And of course =D, these machines were using P&P toner. They must have realized it and adjusted the formula as I haven't seen it yet =D.

Lol, I clearly remember the first one I saw, damn 1820 was in a closet in a bank, there was a shelf right above the copier(so close that you couldn't raise the ADF most than 2 inches), and on the shelf was a coffee maker, creamers, sugar packets..... Poor customer, i accused them of spilling coffee in there machine =P.

Our test machine is at 30k, no specks yet . OEM ftw.

I was able to buff the drum really hard and the image finally came off. The drum and drum blade have been replaced along with the developer. All wires are clean. This seems to occur every 3 to 4 weeks. Again, after I buff the drum it is fine. I can run several hundred prints and there is no sign of the defect coming back while I am there. Any idea's?

Check customers media, not using unusual paper weights, ensure genuine Panasonic Toner, also check Dev Bias setting (May need readjusted F6-19) make copy lighter, hope this helps !
