Bad copies and prints after changing the drum and toner cartridge
We recently replaced the drum and toner cartridge and everything that prints has lines and blotches on it. I don't know what caused this. It didn't happen immediately after replacing the drum and cartridge, several weeks later. Any help would be appreciated. Thanks Jeff

Hi there. There could be up to three things causing the the lines on your print outs.
1. Toner Cartridge is going bad.
2. Toner drum could be going bad.
3. Your fuser could be going bad.
The one way to test this is to start a print out and as it starts going open the front cover to where your toner cartridge goes in. This will stop the print in its tracks. You might need to do this a couple times to catch the paper in the right area. Pull out the toner cartridge and see if the lines are showing up there. Remove the paper, but be careful though the toner has not been fused to the paper yet and you can get it on your or your clothes. If the lines are showing up then your best bet is to replace the toner cartridge. But if they don't show up then it could be the drum or fuser. Most laser printers have a drum built into the toner cartridge, but there are some with separate drums. The Toner cartridge is the most common cause. Its very rare for a fuser to cause lines but they can go bad and cause a build up on the fuser of toner.
Sounds like a bad drum cartridge. Pull the toner/drum cartridge out of the machine and set it down. Press down on a (blue?) tab to release the toner cartridge, and you can lift the toner cartridge out of the drum cartridge. There is a cleaning blade in there - a soft plastic blade that rides against the drum and scrapes off toner that didn't get transferred to the paper. If it gets stuck off the drum surface, images repeat a few inches (one drum circumference) down the page.
A new DR-350 drum unit should fix it. have the machine's power on when replacing it. While the door is open, touch the CLEAR key. The display will read "REPLACE DRUM?" or something like that. Press 1 for Yes.
If this model comes with the drum separately of the cartridge, only replace the cartridge. There's no need to change it every time. until prints start to get lines or dots. Don't expose the drum to light too much.
Depending on the age of the model, it could be a couple of things. ***Never touch the drum or expose it to bright light*** The drum unit is bad. It's the shiny brightly-colored large roller in the center of the machine. On most recent smaller machines like this on it's integrated into the toner cartridge. Check it out. If it has toner build up on the ends, it's bad. or The corona wires need cleaning. Some machines have a small slide that moves from one side of the printer to the other which cleans the hidden corona wires. It's usually brightly colored.
The corona wires are also integrated into the toner cartridge in many smaller machines
This could be a drum problem, the drum is part of the toner cartridge in this printer.
If the toner has leaked it will be all over the inside of the printer - you'll see it. I don't think that's the problem.
If the toner cartridge is an original Dell item, then it's likely to be replacable under warranty.
If the cartridge is a remanufactured item, it may be that the wrong toner has been used. Toner is NOT all the same, and this cartridge is one whe the wrong toner really will not work properly for long.
The chances are the changing the toner cartidge will cure the problem, provided you use an original Dell item, or a remanufactured item from a reputable manufacturer.
You either have a defective black toner, a bad fuser or transfer belt. From my experence it is usually a bad toner cartridge. After you print a couple of pages, pull the black toner and see if there is anything on the drum. If there is try shaking the toner, sometimes toner does like dirt and clogs up. If you still have problem you will have to try another toner. I know that is not cheep, but I don't know any other way.
your laser printer
1) print color quality is now distorted that means print skew (technician called)
2) print tint means the print color not enough density,
3) print mottle means print dirty
you may try
1) print distorted--- find out the skew adjustment from your printer manu, it is adjust the image before transfer to the drum.
2) print skew could be happened when the drum replace install not very accurate, so install it more carefully.
3) print tint---you may increase print density from the manu, not fix,
4) print tint---the toner caridge near life cycle or using the less compatible toner. so you have change the quality toner or cartridge (if near life cycle) to improve quality photo print
5）print mottle---toner quality ? or cartridge near life cycle also cause print dirty paper,
if the paper is coming out blank then there is a problem with the Primary transfer.
this is located on top of the drum, it is a thin wire that charges up to make the copies, it may be broken not sitting correctly or bad.
take out the drum and look for a thin wire that is on the top of the drum,if you cannot find it replace the drum
This Machine needs a copy cartridge. Replacing the toner will not clear it. The copy cartridge is the drum unit which is why the drum light is on. With the new copy cartridge a chip on the cartridge will reset the counter and clear the "CC" and the drum light. If you cant find this I can send you one. I believe on this model it is user replaceable.
