    I even put in a new toner and still had the problem. Cleaned inside with canned air. What the heck is a fuser?

Hi there,

I believe there are 3 possible causes for this issue; toner drum, fuser or transfer roller - more than likely I would dismantle the printer and check for lines on the fuser. But just in case remove the toner and carefully release the flap to reveal the toner drum - if that is scored and the lines correspond to those on the print-out thats the cause.

the two places to look is transfer roller and the fuser unnit.
i think there is a problem with the transfer roller it is under the toner and it needs to be spring loaded. The paper passes between the toner an the transfer roller to charge the paper en let the toner stick to the paper and if it doesn't make correct contact then it wont work

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.

Epson 9800 Prints black dotted vertical line


This is a workaround - I too need a definitive answer. Symptom: black dotted vertical line 1/2 to 3/4" from leftmost image edge. I have begun adding single vertical line to my prints .25" from the left edge of the paper to force the "dots" off my print - this seems to have the desired affect, but it does not answer the cause or provide a true remedy (it will save many of your prints while we wait for complete solution). dkh

Hi there check that it isn't the drum unit by turning the machine off open the top cover remove the toner and underneath you will have the dev unit unplug and lift out then remove the transfer tray (the one you open if there is a jam) open side door remove waste tank then you have the drum unit now to remove there is either a push button or a screw do either one that corresponds and check the unit. If there is a black line on one side the only way to get rid of the line is to replace the cleaning blade as this has worn. you can clean the drum unit cleaning blade it may only be toner stuck under the blade all you have to do is rotate the drum the opposite way of operation and if you have to hand a air line just give it a blast failing this it will defently need replacing.

Hope this is of some help
Please rate me
