We have prints that have faint black lines (vertical) on the left edge of the paper. The lines go the full length of the paper and are approx. 1.5 inches wide. Is it the black photoconductor unit? Before I spend $$, I would like to be sure.
Also have faint black lines on left side of page. We've replaced the photoconductor unit once before in July 07. We purchased the printer in Feb 07. The problem started again in Feb 08. We were told humidity and/or temperature changes cause these lines. We really don't want to buy a new unit. Is there a way to clean it?Also have faint black lines on left side of page.

We are having the same trouble and we just got ours about five months ago. Quite ridiculous if you ask me. It's in a climate controlled room - our computer lab in the school.We are having the same trouble and we just got ours about five months ago. Quite ridiculous if you ask me.

We have had this printer for less than a month and experienced the same problem. We contacted manufacture and they sent us out a new black photo conducter which we installed only to have the same problem occur again a month later. After 4 months of this we brought the printer in and were told it would be over 400 to fix which is more than a new printer.

Just go to printing options and fix the print quality. No more lines then.

Hi best way to check is to remove the black photoconductor and you should be able to see the little lines on it also check the the black dev/toner unit for the lines. most likely to be the black photoconductor unit though.

Vertical bands of faint black are generally caused by filtering capacitors and can be found in the power supply or the 5 volt supply or even the Video processing circuit...it is not an easy task to identify the source of Video hum bars.....we also call them Jailbars.
Another problem seen is faint black lines caused by the TV set being in 4:3 mode all the time....right at the edge of where the picture ends and the black pillars begin, we see a faint black line that never goes away and is normally seen with a full screen....
That is actually image retention, but it's caused by the crystals that create the picture becoming polarized or ionized over a very long period of time....and it's not easy to DE-Polarize them !
But there are some theories out on how to do that.... Certain people suggest running the TV overnight with an ALL-WHITE picture and some suggest an ALL BLACK PICTURE...and some suggest alternating between both !!
Now, a black picture is easy to make, you just deactivate the Video Mute (blue screen) and set it to an unused Video INPUT overnight....
About the only way to make a white screen is to use the USB port for pictures and take a very bright outdoor shot of a piece of white paper that hopefully is out of focus too....That would create an all-white picture that you can plug into your TV set overnight....
Now if you decide to try this, deactivate any displays on your TV set...all you do is press the display button until the Video and/or USB input numbers disappear....
Next day , set it back to normal TV and see if it's gone or if it's REDUCED....try it again if needed, or try the exact opposite if you see NO RESULTS....
Couple possibilities:
Fuser hot belt has wear lines transfering to the page
Black pcu needs to be replaced
Transfer unit is not being cleaned properly and needs to be replaced.
Remove each of these assy and inspect them for wear or lines that corespond to the lines on your prints.
Are they lines from one edge to the other in a straight line. Or is it faint reprint across the page?
Thin lines would most likely be a bad drum or cleaning blade.
If it is faint reprint it is the heat roller in the fuser.
Do the black lines only show up when useing the adf???? Or do they show up on both the adf and the copyboard glass??? If it is only when using the adf...... The fix is easy.... you have to clean the smaller piece of glass that is to the left of the copyboard glass with windex or rubbing alchola. If it is with both you may need a new drum and blade or a new ufr... Good Luck

Same problem, but it appears to be all colors. And only on the left side.
