Images are printed with a glossy finish. In the [Quality] tab, select the [Glossy Mode] check box.
During the printing process, paper, toner and dust particles can accumulate inside the printer. Over time, this buildup can cause print-quality problems such as toner specks or smearing. This printer has a cleaning mode that can correct and prevent these types of problems.
Mix one part distilled vinegar to 10 parts warm water in a spray bottle. Wipe down the window with a a soft, clean, lint-free microfiber cloth or paper towel to remove dust before you spray your solution, then spray the entire surface.
Never use alcohol, thinner, or corrosive solvent to clean the scanner. These chemicals can damage the scanner components as well as the case.
Use isopropyl alcohol or ethanol according to the manufacturer`s safety guidelines, as applicable. Wipe the roller with a lint-free cloth dipped in isopropyl alcohol or ethanol. After cleaning the roller, make sure that no lint or other material remains on the roller.
In terms of tips for cleaning paint rollers, first scrape the unused paint back into the tin with a putty knife and roll it on a rag to remove excess. Disassemble the roller, rinse with warm water, add detergent and work it into a lather to remove the rest of the paint.
Documents such as photographs, web pages and PDF files can be printed easily to Konica Minolta-certified output devices via a wireless LAN.
Some printer models have a cleaning cycle mode.

Look for this option on your control panel or look it up in your manual to run the cleaning function. If the paper drawers are easily removed from the unit, take them out and clean them with a damp cloth to remove any dust or paper lint.

black smudge lines
ANSWER : Not knowing if the drum is OEM or remanufactured or if it is way expired, only thing I can suggest is looking at it. Take the toner out and turn it manually with your thumbs on the gear. The drum should be clean all the way around.

smudged parts on printouts
ANSWER : You don’t give enough detail. It’s doubtful the new drums would cause smudging. If it’s just one color, then look at the surface of the drum. It should be visible. If you don’t see it on the drum and it repeats several times on the page, then it would be a worn or dirty surface on the fuser.

smudge line across the page 3/4 way down
ANSWER : Only 2 things can cause it, the toner or the fuser. To determine which, you do a half-stop test. To do so, put a sheet of paper in the manual feed tray. Then send a print job while you watch the page. You want to open the lid about the same time that 3/4 of the page has just passed by the toner cartridge. Might take a few tries. This will stop the area with the problem after it passes the toner cartridge, but before it hits the fuser. You look at the paper and if you see the defect, then it’s caused by the toner cartridge. If not, then it is being put on by the fuser. It seems a bit strange to me because normally a defect like that will occur 3 times per page, which is about the circumference of the toner drum or fuser sleeve.

Smudges down right side of paper
ANSWER : That doesn’t make any sense. Sheets that feed from the manual feed or the cassette tray both converge before the toner cartridge. That would mean that the smudges would somehow be put on the paper as it was feeding upwards from the tray. There is nothing in the printer that could account for that happening.
