I'm getting significant grey streaking running lengthwise on the front of my printed pages. No LED's are on other than the green 'ready' light. The printer is 4 years old and this is the original toner cartridge. I removed the cartridge and rocked it back and forth. That didn't help. Any suggestions?

Re: Grey streaking on printed pages
You need do follow steps:
1) take out the cartridge find a cover there is the drum inside, the drum you can see the color on the drum surface
2) check out any pieces of paper or dirty waste toner stuck there, because there is a waste toner cleaner cross drum surface
Laser printers are charged using a drum which produces an electrostatic image. The drum could be unable to hold all of the 600v charge or be be scratched if the streaks are always in the same position the the drum is not holding the charge for the toner to attach to and therefore the drum is faulty and beeds to be replaced

sounds like your heads are all gummed up with dried ink.Is this a older printer or previously used if so run the cleaner that should have come with your printer software. keep running it until clean or bring it to get cleaned.
The streaking could be anything internal to the printer, such as the transfer belt or a drum unit. As for the lack of color, that sounds like it is a setting in the print driver that got changed from printing in color to printing in monochrome or grayscale. Look through your print driver settings to see if you can locate this setting and change it back to color. Also, once you print in color again you may notice that the streaking is a specific color, which will help to troubleshoot that issue.
Sounds like a bad fuser. To check it out - print a few pages, as the printer prints open the cover(the one that you open to get at the toner).Remove the toner. Look at the page that is facing up. if it has streaks on it - change the toner. If it looks clean, change the fuser.
If the streak is like a thin double image line, or the print feels like it rubs off then it is coming from the fuser film. The fusing units are fairly inexpensive and not hard to replace but if you have to have someone do it for you then it might be just as cheap to get a new laser printer.
Look at the exit section of the printer where the paper comes out. The fuser film is a grey "roller" that sits on top of an orange roller. If you can see the grey sheet you may be able to see the defect line in the middle of the sheet that is causing the line.
More than likely the grey streaks are from dirty fuser rollers open the fuser area and insect the fuser rollers i think they should be grey take silicone lubricant and wiat ntil rollers cool down and clean with a coton cloth do not scrape with anything sharp if this does not work then you ned to remove the glass platen and clean the optics( mirror and lens with tissue and glass cleaner wen machine is not hot also insect expsoure lamp( do not touh lamps because the oil from your hands will cause the lamp to get extremly hot and burn out good luck
One other thought is there could be marks from the stripper fingers at the fuser section look for build up of toner on them if so clean with q tip and alcohol
It is the fuser at rear giving you grief! The upper heat roller has a teflon coating that wears away allowing toner to stick to roller and smudgin prints as they pass threw it. The fix is to replace fuser assembly, take to brother dealer to fix.
You can prove it to yourself by timing the print to stop mid way threw machine then remove print cartridge and look at paper, you should see a image is good untill it hits the fuser,( pre fused image "rubs off" paper.) If you have changed drum and toner thats all it can be. They all do it in time.
Fuser is hot bit at rear, pull out drum and look in the back with a small torch you will see upper heat roller is worn, guestimation $90 for fuser plus labour to fit.
