Developer housing
I have swapped drums - say k with m - for troubleshooting purposes. Swap chip (if it has one) and cut plastic key, run 1 copy without much toner on it. Heck, maybe try a used transfer belt. If you...
Mr. D, Is the toner OEM? It seems you covered all the bases. Maybe replacing the sensor?
Can't get into admin, tools, or upgrades. All locked. Cleared all NVM. Tried a forced upgrade, wouldn't take. Trying to get to factory settings - unable to find out how. Anybody know how to fix this?...
Then adding dev may be all you need. I use a plastic spoon taped to an aluminum rod. I need to form a "funnel" in the spoon so less comes out at once. But what did you do to fix it?
Joel, Replacing any parts or supplies will not give you immediate results. Developer has to be added, or the housings replaced. The dev housings are short on developer. Look along any color mag roll...
All 4 colors, using OEM (not rebuilt) drums & supplies? I would suspect power supply issues. Dev is being pulled to the drum, emptying the dev housing. I would add dev and troubleshoot any PS issues.
Thankx for the reply. Got confused I guess. Thought the 78 series finisher is XLP.
I would agree, but it does seem strange that non of the "takers" have reported a hacking issue.
The plastic on the turn baffle wears. For Foam replacement, the orange foam strip inside the heat belt of a 78 series fuser works excellent, although the suggested vhb tape is worth a look. Probably...
The way I fix that problem is to eliminate the "switches" from the circuit. Rewire the fuser so they are out of the circuit, and always in letter paper mode. Yes, you are right: it won't do...
Anybody hear of using a larger than 4 gig pen drive to install firmware on the B400, b605, B615 series, will disable the usb ports, thus rendering the machine unrecoverable: Toast?
TIA
Generic toner for the 78 series may contain substandard developer that can cause clouding. Otherwise, the developer never wears out because it uses a trickle system. In other machines the mag rolls...
Generic toner, plugged waste auger system comes to mind.
May I ask what prolibro is?
Unable to do this procedure. Customer needs to print odd size originals from usb, some larger than 8.5 x 11. They need to be reduced and correctly oriented. Customer says his 7545 at another location...
Yep. The belt was slipping. Runs great now. Must be getting old....
Replacing the DH would eliminate any suggestion I would offer except if it had the same defect which could be a loose top cover latch. Try putting alittle pressure on the top cover. A ream of paper...
Guy, Ya know, that is probably it. Didn't think of the belt slipping, but it sure stands to reason. The drive pulley is so small - not much surface area, and the grooved side of the serpentine belt...
Don't know without looking in the manual
Can get it to pass paper by removing the transfix load springs. With the springs connected, it jams paper at the transfix roll. Cams are not cracked or spun, bearings on the removed TF roll are free...
It'sjust Xerox fuser oil, not fuser lube, and not fuser agent. Maybe they would work, but have not tried it.
Never measured it. I just run the oil down the wicks to semi saturate it, and it seems to work at least temporarily.
