- Was there a paper jam and when the paper was dislodged the next few sheets were streaked? Running a few more pages usually clears this.
- Is this a new toner cartridge? Did you just change the cartridge? Are you low on toner? Try removing the cartridge and gently rocking it back and forth, side to side. This will distribute the toner more evenly.
- Is this a heavier weight paper then previously used? Try going back to the old weight and see if the problem continues.
In my experience if you refill the toner cartridge with the toners available in the market,though they are labelled"for Brother 2140" you get vertical dark patches on the paper. Once in a while you get good quality print too. Replacement with correct toner cartridge seems to the solution.
I saw a defective toner cartridge in a Brother just last month that left solid drips of toner on the page, so thick they peeled off in lines. If that's what you're describing, take a sample back to the store along with your toner cartridge, and they should exchange it. Might want to call ahead and see if they require bringing in the printer too. If you're seeing thin, straight lines, and they were also showing before you replaced the toner, then you either have a drum or a fuser roller with a scratch around it. You pull the drum unit out every time you replace the toner. It's the assembly you install the toner in before putting the whole thing back into the machine. The fuser is much harder to get to. It's the hot section in the back that makes the print permanent by pressing it between hot rollers. There's a simple, but scary test to see which part puts extra marks on the page, and that's to deliberately jam the printer. Start a test print and wait until you think the page is past the toner/drum assy. and headed for the fuser. Open up the printer, stopping it, and pull out the drum. If the paper is past the drum and headed for the fuser, look to see whether it has those lines on it. If it does, the drum is the problem. If the print is still clean, the fuser is the problem, and you're looking at a repair.
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.
The HL2700CN is a Tally machine rebadged by a number of manufacturers. Each has it's own unique 'plug' on the back left side of the cartridge as you look at it in the machine. Check that the plug is the right shape and if necessary fit the one from your empty 'brother' cartridge.
I have only ever had the 'illegal toner' message when I put in a Lexmark cartridge by mistake - swapping plugs solved it.
'Brother' machines seem to run at a different temperature than other Tally clones - so there may be a deeper problem with the toner that you used. In my case it simply failed to fuse to the paper and I had to get another cartridge. Check for deposits on the OPC belt and fuser rollers.
