Model 600. Why is it dropping toner near transfer corona unit?


When is the last time the developer and drum where replaced? When the last time was a PM done? Very 250,000 copies a PM must be done? Which replaces the Corona Wires, Developer, Drum, Corona Grid, Web roller for fuser (Hot Part). Also during the PM the Tech should clean the toner out of the Waste Toner collection unit on the image unit. also clean the area around the drum and developer roller.

Preventive maintenance time konica minolta bizhub 600


Yes every 250,000 prints the following is replaced

Developer, Ensure counter is cleared and Developer Charge is run
Drum
*Corona Wires and Corona Grid
*Transfer / separation wires
*Cleaning systems for above wires (Unless Cleaning system motors are shut down
*Fuser Web roller
also all of the above counters are cleared as the machine use the counters to determine what is new and what is old. And determine what voltages to assign to certain assy. if you lie to it and clear the counter and not replace codes will show up and image issues can happen.

* KIT PARTS
Developer and Drum separate

Should also check the upper and lower fuser roller located I the hot section and the fingers that protect those large rollers from allowing paper the to wrap around them.

Again clear counters!!!!!!!!!!!!!!! and run require developer and drum procedures. Try this as start

I have a Kyocera KM-5530. It prints light in some areas. There is good transfer to the drum, but just not to the paper. New corona wires, new main high voltage board, new developer, and toner. Anyone know...


This would indicate that you are having a transfer problem or the Paper is very damp. Have you changed the transfer corona wire?
Also check the drop down mechanism that holds the transfer unis. Mechanichaly if it is not in the correct position when in the locked position this can cause the problem that you are experiencing.

I have a white stripe on the copies. I just installed a new toner cartridge, and cleaned the transfer charger. I have a Sharp AR-162S copier that is 3 - 5 years old. Thanks.


Hi check the developer unit make sure it is coated end to end some times the blade on the developer gets foreig matter stuck and prevents the developer/toner to go onto areas of the developer mag roller also check and make sure the transfer corona wires are in good condition no black marks on the corona wire if there is replace the wires

Sharp ar-120en photocopier showing f2 and red dotted warning light on


To be honest, I don't recall an AR 120. But the lower end AR series are pretty much the same, on error codes and maintenance.
2 separate issues. The dotted circle means the DEVELOPER needs to be changed, NOT the toner. This means that it has been 30000 copies since the last developer change. The machine is dirty. Dirt/toner is what causes the F2.
This is something a technician must do, unless you are a tech for another brand of copier, then I can tell you what to do.

The F2 is a dirty sensor in the drum area, up by the charge corona, inside the copier. Usually, it gets covered by toner because the developer needs changing. You can try removing the charge corona and shoot it with some canned air up into the corona cavity, and the corona itself. If the corona doesn't pull out, 1 screw just above the corona needs removed. The charge corona is located at the top of the middle of the copier, facing it, with the door down. It has a green end sticking out. You have to be careful taking it out and putting it back in, because you can scratch the drum, and you do not want to do that! 150-200.00

What is the difference between the toner and developer on this printer? The manuals we have don't give any info on installing developer, but you can purchase both toner and developer for this...


Toner provides the color, Developer consists of magnetic particles that carry the color on the outside of the developer drum, which is magnetic. Some developer is lost on each copy, although most stays in the developer unit. When you run low on developer, your image gets lighter and lighter, until the machine reports an error because it can no longer self calibrate. One change of developer suffices for many changes of toner. There is a procedure involving various actions and codes to flush the developer material out and load new developer in. This is not difficult, but there are a couple of reasons you might not want to do it if you are unsure why or if you should. First, developer for these estudio copiers, is very expensive. Second, unless you know how many copies have been made on the existing developer, you might change the developer, and fail to correct the problem. There are related service items, involving the cleaning blades, and seals, servicing charging grids, corona wire, and general cleaning of the 4 developer units and opc drums. Including dusting with zinc sterate, etc., etc. Its hard to know where to begin or where to stop. If you really want to know all about it, order a manual from any of a variety of on-line sources. Good luck

Aficio 1085 toner pread in drum area


the blade is not sitting correctly either you have used a bad one or the mechanism is not adhereing closely to the drum, removed the uit and rotate towards you sprinkle a few toner if you can still see a remainder toner that was not yet scraped then the prob is really in the cleaning unit, either the blade or the plate,
to ensure have you consider changing your drum? it could be exhausted already...

no other way around it

Corona wire


I was getting the clean the corona wire problem message even after repeated cleanings.  Before this problem occured the toner light was flashing warning of low toner. When I got the clean the wire pop up the toner light was on all the time indicating the toner was depleated.  So, I thought I would try replacing the toner cartridge and see what happened. I opened the new toner box and noticed on the foil packege specific instructions to clean the corona wire when installing the new toner.  I installed the new toner and cleaned the wire one more time. I then reinstalled the drum and toner assembly into the printer and the clean the corona wire message did not come up again.  The printer now works fine.
