That usually indicates a worn heat roller in the fuser assembly. You can get a fuser from Amazon or other online site. They are user replaceable and run about $80-100. Do a search for T620 fuser and you will find them. Part number 99a2402 What happens is the Teflon coating on the fuser wears down which allows the toner to stick where is should not stick so it gets deposited on the paper in other locations and leaves spots.

SOURCE: vertical black line down right side

Did you carefully inspect all through the paper path for some fuzz, or a small piece of paper smearing the print?
The other issue would be the fuser. Do you see any reprinting of images or letters in that area?
What you can do is set the machine to print 2 or more pages and open a cover or turn off the power to jam the prints in the machine. See if the line is on the drum or not. If not then you have a fuser roller issue which would require replacing the fuser.

check the "photoconductor unit" (pg 37 in the Maintance manual)

ours was doing it with the magenta and saw a faint 'scratch' on the roller. will attempt to replace and report back if this fixes it.

Tip

When u print if u r getting the Horizontal or vertical line then follow these...


If the print is a dismal gray rather than a sharp black, you are probably almost out of toner. This can manifest itself evenly across the entire page or in splotches or stripes, depending on the printer.
Sometimes you can wring a little bit more out of a toner cartridge by taking it out and gently shaking it from side to side (never up and down, as toner can spill out). You can also try turning up the printer’s contrast adjustment, if it has such a knob (usually on the back side if it exists). Faded print can also result from a dirty corona wire, because a dirty wire inhibits a full electrical charge from being passed.
If the printouts are consistently varied in density, and you have to frequently remove the toner cartridge and shake it to redistribute the toner inside it, make sure the printer is sitting on an even, flat surface.
Horizontal black lines
A horizontal black line on the printout is probably the result of a dirty or damaged roller. There are lots of rollers in the printer, and you can use the space between the lines on the page to determine which roller is causing the problem. Measure the distance between the errant black lines on the page and then use Table A to determine which part might be causing the problem. Table A
Distance between lines
Faulty part
0.5”
Registration assembly
1.5”
Upper registration roller
1.75”
Lower registration roller
2.0”
Toner cartridge developer roller
2.56”
Lower fusing assembly roller
3.16”
Upper fusing assembly roller
3.75”
Toner cartridge photo drum
Regularly spaced splotches
If there are evenly spaced black spots but they don’t extend all the way across the page, the problem is probably a scratch or flaw in the drum or a build-up of toner on the fusing roller. If the spots are less than three inches apart vertically, it’s probably the drum, because the drum has a larger diameter than the fusing roller.
Vertical black line on edge of page
This can indicate an almost empty or faulty toner cartridge or (less frequently) some spilled toner inside the printer.

Need to reset ink levels on printer (lexmark 2600)


Hi
It is the chips on the inks that make it shore empty nothing you can do about it.

But I have found this bit of read up on the internet forum Gave it a go may work if it works come back let us know so I can pass it on to others Thanks.

1 Take a small pice of clear tape. Try covering one of the outside vertical row of contacts at thr front of the cartridge. Re-insert it and it shoudl "fool" the printer into thinking it is a new cartridge. It works for my Lexmark 2600 series all in one.



2 Use clear tape over left hand row of sensors on front of cartridge and re-insert. ink now shows with question mark but reads as full and prints fine.

3 I had fully covered the contacts because it was the full length of my Scotch tape. It did not work. I went back and re-read thread, wiped the contacts the computer was telling me, took off the strip and put on just a sliver covering the left vertical side of the contact only. It worked! Yippee! Thanks a million!

Black marks


Replace the toner cartridge; this happens periodically, especially with refurbished cartridges. Parts of the cartridge can go bad even though the cartridge itself still has ink in it.

Toner specks along the edge of the page


Rev. Gregory.
Its looks like you have a small pinhole, or divot, on a imaging conponent that is common to all four toner cartridges. Remove the drum unit from the prtr and keeping the green handle close to you pull back the shutter which covers the drum, and look for spots of toner at the either end. If you hold the page with the spots on it, with the leading edge centered and touching the drum, it will give you some idea where the edgeis relative to the end of the drum. If you can't see any corresponding spots on the drum surface.
Put the drum unit back into the prtr and allow the prtr to restart, then switch off and remove drum, this will have turned the drum to a new position, and should show any defects. Only expose the uncovered drum to light for a minute at a time, and avoid touching the surface.
Let me know what you find.
Cheers

BLACK LINE ALONG RIGHT SIDE OF LETTER SIZE PAPER


Is this and Okidata C5100? And is the stripe vertical up and down on the page? I'm going to assume yes to both of those for the sake of trying to help. Worse case is the fuser unit in the machine is wearing in one spot and thats why the streak is appearing. Also, many color printers require a seperate drum unit or photo conductor unit. These could have a wear spot on them as well. They can fail long befor the change drum light appears. Other than that remove and inspect the black cartridge. If there is a shutter on it, pull back and inspect the two inner rollers. You're looking for any wear spots in a location that corresponds to the streaks on the paper...or an excessive amount of toner leaking from one spot on it. Hope this helps!!

Printer doesn't print even with new ink cartridges.


turn the printer i turned on and Press the cleaning button ,. Cleaning takes about two minutes, the printer makes some noise when it finishes you run a nozzle check for print quality and reset the cleaning cycle.
load paper . go to the printer menu as follows: click Control Panel, and then double-click Printers. Select the Epson printer if have more than one printer is installed. Click File, click Properties, click the Utility tab, then click the Nozzle Check icon.
The printer will print a Nozzle Check pattern in black, and in cyan, magenta, and yellow. Each staggered horizontal and straight vertical line should be complete, with no gaps in the dot pattern. If any dots are missing, clean the head again.

If your software is different, and does not have these options, you can do it this way:

1. Same as above.

2. Same as above.

Turn off printer and computer. Disconnect interface cable from printer. Load paper. Hold down the load/eject button and press the power button to turn on the printer. Release both buttons.

3 Same as above.

4 Turn off printer and reconnect the interface

Cleaning page


Ideally just replace the toner cartridge. But if fairly new, just clean the loose toner off from the old cartridge's printing surface by swabbing it as you manually turn the drum. If while doing this you notice black burned into the glassy surface of the toner cartridge or scars along the surface you'll just have to replace it. Happens once in a while, especially with refurbished cartridges.

Two black dots on right side of page


Are the marks in the same exact spot on each page? If not and you have changed the toner cartridge then most likely the fuser assembly needs to be replaced. This is a job I recommend for a professional.
Good Luck
