I have an ML-1710 Samsung laser B/W printer. It's producing a one inch wide gray/black smudge down the exact middle of the page.

If the problem re-appears and updating the firmware (from office.xerox.com) does not help you are most likely looking at a replacement processor board.

SOURCE: Samsung ML-2010 Mono Laser Printer leaves unwanted marks on page.

if older printer or well used printer (All laser printers if they have print quality issues - it is mostly either the toner or the fuser). the only way to tell is get (borrow) a toner and see if problem is the same or remove the fuser (the hot thing in the printer) and see if the "ironing" unit or fuser rollers are dirty or worn out or scratched

SOURCE: Faint vertical lines on Samsung ML-2010

Was the toner remanufactured/ compatible?
Sounds to me like the doctor blade in the cartridge is 'gummed' up and not allowing the toner to flow evenly across the Developer roller......try another cartridge

SOURCE: Black vertical line (1 inch wide) appears while scanning/copying

For this kind of problem you need to call the tech support because the printer is already messed up and it is in need of replacement

Hope this help

SOURCE: Horizontal lines appear every 4 inches on each

User manual page 6.17 says:
Horizontal streaks indicate improperly installed or defective toner cartridge. Try re-installing the cartridge.
