Showing line in printing


Are the lines white (no toner is printing on that area) or black (too much toner is printed on that area)? In the first case, you might have dirt on the developing unit, the best bet is to replace the developer and before cleaning the developing unit. If the second case is you case, you might have a broken drum (scratches on the green drum that you'll see while the right door is open) or the charging unit might be dirty; in these two cases, you should replace the drum unit. The same black lines appears if the fusing roller is scratched, in this case you should replace it. Just drop us an email at office@bizhubreset.com and we'll assist you further.

Keys are under the drum of a model #ATF600FSO; how do I retrieve them?


You will need to try and see if you have a front access panel you can take apart from the unit, underneath the drum and access the pump area and see if you can locate your lost keys.

I have a peice of paper jam in the output area of the imagerunner 1670, but the machine dosn't open to allow access to this area. how do i get the paper jam resolved.


Your jam is in the fuser section of the machine. Unfortunately this area this area is not for users to access. You will need to remove covers to get to the fuser unit. You may be able to access the paper by removing the whole drum unit (make sure you remove the toner cartridge first). Then look into the machine to the left. You may see the tail end of the document for removal. Otherwise, you will eed a service manual to dis-assemble it yourself.

DRUM UNIT REPLACEMENT


no screws to take out make sure all the toner levers are locked down so toners cant slide out. kust below the toners is a lever that will open the drum cover when you open this it reveals the drums just slide them out

POOR COPY QUALITY


Here is the scoop! There are two (2) components to the fax machine, one is the scanner portion which is located just past where the paper you are copying or faxing enters the machine, separate the two sides and access the imaging plate, clean this area with denatured alcohol.
Step two is to clean the toner and drum unit, get the mirror at the back of the toner and under the toner. If after this you are still getting lines on the prints you will have to replace the drum unit KX FA-84 about $85. Happy faxing, Ken
