There is probably toner spill near the sensor. Take out the K toner unit,careful it is 2 parts, toner resevoir and drum, Then clean the toner spill. The K sensor is located on the right inside wall acrooss from the k Drum. Try to clean the sensor with a cottom swab and alcohol. Hopefully this will clear it. If it does not, you need to have it serviced,Tthe sensor board is held in with 14 springs and it is a bear to deal with.

Good luck,

Drum light is on

This usually means that you need to replace the drum on the printer. Most likely it's under 10%, because that's when the warning light comes on. Depending on the printer, you may have 50-150 pages before it completely fails. I would advise to get it replaced soon.

Reminder: A drum is NOT the toner. It's normally a device that may house the toner. Or a separate part.

Getting black lines on copies on Brother MCF 6490cw all-in-one printer/copier. How can I clean the rollers or internal mechanisms which are making the lines?

More likely than not, it's either the imaging drum or the toner causing these lines, and not left over toner on the rollers. Try replacing the toner and see if that works, if not, put the old toner back in and try replacing the imaging drum

Oki 5150 color are not print right

You need to replace the magenta drum. Just because there is life left; it's possible it is scratched. Also, take a cotton ball dip in alcohol and wipe the LED's off when the cover is open; those black things that are hanging down from the cover. Also, make sure your drums are installed in the proper spots (magenta in magenta slot). If the toner "rubs off" after it prints... then the fuser is defective.
