I recently bought remanufactured compatible toner cartridges for the 5100cn online from nexiimaging.com.  I put them in and they worked fine for about a week and a half.  Now whenever it prints - the whole page is covered in magenta or cyan toner.  I read other posts about this problem and it was suggested replacing both the transfer roller and imaging drum which I did earlier on Monday of this week.  It printed fine for about 100 pages and it's again covering the page in a magenta/cyan mixture.  I keep switching from "dell" to "non-dell toner" to see if it makes a difference and it  doesn't.  Initially - when the new toner was put in, the option to "non-dell" toner was not turned on but i never had any problems with the first thousand pages or so.  Currently - every 50 pages, you'll get a handful of pages that print almost normal (but still  have a pinkish twinge to them) and then it goes back to covering the page.

 

Is there something else wrong with the printer? Would replacing the cartrigdes with DELL toner ones help?  Is this machine doomed?

 

thanks.
