Re: splotching and spotting ink
The roller cleaning will require you to remove cover to clean the full roller with alcohol to remove ink build up. Have you tried to just run/feed a blank piece of paper through to see if you have roller ink roll off?
This also sounds like a bad cartridge with clogged jets...

If you are seeing vertical streaks/black lines your primary corona wire is dirty and or the fax scanner may be dirty. 1)To clean the corona wire you take the drum unit and toner cartridge and place it on disposable paper to avoid spilling. 2) Clean the primary corona wire inside the drum unit by sliding the blue tab from right to left several times. 3) Return the blue tab and snap it into the home position. 4) Reinstall the drum unit and toner cartridge. 5) Close the front cover. Caution: if you do not return the blue tab to the home position it may repeat the black lines.
This is usually due to a dirty imaging drum roller (green roller below toner). Remove the toner / drum assembly, then separate the two. Now slowly rotate the imaging drum roller by hand using the gear on the side of the cartridge (Try not to not touch the drum roller with your hand, as oils from your skin may cause further problems + toner is nasty) Look for toner splotches to the left and right on the drum roller as you turn it. If you see any you can clean them off with a damp paper towel. Then reassemble the printer and hold the continue button down until you hear the printer start then release it; this will print a test page.. Hopefully that will take care of the issue. Also while you got the assembly out of the printer you can clean the glass print-head lens using a clean, dry, and lint free cloth. The print head lense is located within the recessed area in the top of the printer.
- I have seen that happen to a bunch of those printers and that is usually all it is. Let me know if that takes care of it.
You probably have a plugged print head or the black ink feed is plugged.
Depending on how bad it is you may find it easier or even cheaper to replace the printer.
If this is a ink caused problem you stand a chance of fixing it if you are patient but you might go through half an ink cartridge to get it working, If it is stubborn it can take 20 or 30 cleaning cycles before you see any black. You can try using household vinegar (dissolves the dried ink) on a qtip or lint free paper towel to try to clean the print head. To do this you remove the ink cartridge and very gently rub the towel with the vinegar on the print head. This might require you to move the print head to one side so you can see the actual print area (where the ink comes out). Keep doing this until the towel starts to come clean ie not as much ink coming off. Then run a few print cycles and if this works your printer will print as good as the first day you had it.
The next stage would require filling a old clean ink cartridge with vinegar and running cleaning cycles. Usually can be pretty messy and you should rethink buying a new printer but will really clean things out.
It is also possible that the print head has picked up clay or paper lint from the paper and this has hardened like a cement. That means replacement.
Either you're using a low grade ink to refill the cartridges or you're not using it enough to keep the head clean. If the ink is allowed to dry on the print head, simply running the "Clean print head" function doesn't always get the dried ink loose. Remove the cartridge and CAREFULLY, clean it with damp toilet paper. Only go ONE DIRECTION when cleaning. SIDE TO SIDE. When it looks clean, check carefully for any left over fuzz. You can also clean the wiper inside the printer with a damp cotton swab.
if it is a laser multi function machine, there may be toner build up on the fuser roller. also, there maybe some other component malfunctioning. i.e., print cartridge (if it's one of those "all in one" type deals", toner and/or drum (if sold separately), place a service call
First I would suggest performing any head alignment functions with your printer's menu to be sure you have the stepper motor feed adjusted properly. Use the paper you are currently printing on for this procedure so that the thickness of that paper is factored in. If you stil see the banding after doing this, you can use the Advanced Media Control button under Printer Settings in ColorBurst to fine-tune the paper feed adjustment. Print out the "Media Advance.tif" target (located in the ColorBurst/images & Targets folder) to use as a guide. For white bands, you'll need to enter a negative number (to shorten the paper feed).
Sometimes ,poor print quality may be due to ink build up in the maintenance station ..
Your ink cartridges stay in the maintenance station when not in use. Depending on the printer model, the maintenance station may be located on the right or left side of the printer. NOTE: You do not need to remove the cover in order to access the maintenance station.
To access the wiper for cleaning purposes: Unplug the power cord from the back of the printer. Move the ink cartridge carrier to the left by gripping the top of the rubber carrier belt and gently pulling it across towards the right-hand side of the printer. Take a warm, damp paper towel or napkin and gently clean the wiper on the right-hand side of the maintenance station.
