Why is there a dark speckled line about an inch wide along the ride side of my printer paper after I print? -

How can I fix this? The line is in the margin? Is it a toner problem?

you can try another toner thats the easiest thing, but if the line remains it could be wear on the fuser roller - power off the printer, removethe toner cartridge - be careful and look for a small enclosed unit this will have a flap you can move - open this and you will see the fuser roller - look for any wear marks on this - it will have a teflon coating that does wear after a time

As most people have said, it s possible it s the drum assembly. However, it could be the bottom plate. If your printer s maintenance software offers bottom plate cleaning, try that. Or just fold a paper in half and run it through your printer a bunch of times.

It probably is a toner problem, the electrostatic roller is most likely not discharging and charging properly.

it s your roller? do you have Inkjet or a laser printer?

No, the drum is damaged and needs replacing
