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.

How do I change the drum to a Canon NP 7130 Black and White copier?


Could be the drum or the fuser causing your problem. To replace drum you need to open the machine by hitting the gray release latch on eft ide of machine to clamshell it open. Inside you will see th toner cartridge/ dv unit on the far right and immediately to the eft of that is the drum unit. You need to release the dv unit by turning a lever before removing the drum unit. Should probably call a tech to do this for you so you dont scratch or damage the drum. Drum life on that model is about 30,000 prints. Whats the meter reading on that copier?

Pages are lined with vertical lines of ink?


Make sure that your drum unit is scratch free. Vertical scratches on the drum usualy causes the problem you are having, Try changing the drum imaging unit,

Not sure what the following description means: Drum End Soon Then a second warning flashes: Change Belt Unit Please tell me what this means and what I can do to fix it? Thanks Management


Brother laser printers have both an imaging drum and a transfer belt that have a limited life span they must be replaced from time to time. Very similar to replacing your toner cartridge. purchase a drum and belt for your model and they will have installation instructions with them.

Line on left side of printed page toner has been changed and did not fix problem


A line there might not be the toner but the laser drum unit.

The operation below is dangerous - on warm printers you can badly burn yourself, and on all printers you risk severe damage to the drum, requiring replacement.

Opening the printer should show both the toner unit and the drum unit, with a usually green metallic drum cylinder. Taking the utmost care never to touch the drum with your fingers, extract the drum unit and check for anomalies on the RIGHT (where the left side of page goes) side:

- scratches: unfortunately, nothing to do. Drum replacement is your only option.
- black sooty lines: wipe them with a clean, dry, lint-free paper towel. Usually caused by:
- small specks of dirt lodged between the drum and the drum shell. You can remove them with a wooden toothpick. Never use anything sharp near the drum, it scratches very easily and scratches aren't repairable. Sometimes it is possible to raise slightly the shell so that a gap appears between shell and drum, and a folded dry lint-free napkin can be shuttled back and forth to clean the groove from dirt and ink clots.

Replace the drum and print two test pages. The first will usually be very dirty because of the toner loosened in the drum.

Drum roller scratch


Not that I know of because most drum units used in today's printers are not designed to be dis-assembled and individual parts replaced. It could possibly be done, but it might be hard to find the individual parts and in my experience even if you could find the part it may cost almost as much as the whole drum unit.

Color Photo Conductor Unit


the vertical line that you saw is an indication of either it is normally worn out, or something has caused the scratched, by any material ( PC drum is very sensitive to any material and can easily damaged or scratched any solid and unwanted dirt inside) see you actual meter reading. if it falls on the first thousand copies or print then it might have caused by a scratched, if it falls beyond the PM parts repalcement then there is nothing you can do but to replace this.

sometimes you can swap the colors, by the affected color use the yellow drum unit to the affected drum, the vertical would not that be obvious.
