Smudges on color printing - Black OK

Color print smudges about 6cm down the page and 8cm apart. this is then repeated about 14cm down and then 26 cm down. This problem has been posted to Epson and they say it is the Photoconductor. The printer has only done 2500 pages !! On inspection the inner of the top cover has some plastic mold marks which are 8cm apart so ran the file over them and hey presto - no more smudges! It looks like Epson have not left enough space in between the cover and transfer roll so as soon as your Photoconductor ages the surface bulges out where it sits on the rollers and then scrapes the cover.Hope this helps other users to save the purchase of a new Photoconductor!

    I am dutch and I don't understand the exact meaning of the sentence:
    on inspection the inner of the top cover has some plastic mold marks which are 8 cm apart so ran the file over them.
    Is it possible to explain your solution in an easier language.

    I have tried a lot of things, but i don't understand the exact way to do it.

    Hi I have a problem with mu epson c1100, when I print in colour I have a line going vertically down the left hnd side of the page. It is roughly 1ch in width. Epson have told me that I need a new photocondutor but i have only done 1800 pages, so cant see how I can need a new one already. Noticed a thread about filing mouldings, don't quite understand it though. Can anyone help. Please. Arienne

    I am also having this problem and would appreciate the solutin, I have removed the top cover of the photoconductor but I am unsure what I have to file.

    I have the same problem, there were smudges according to where the lines of the top cover of the photoconducter are.
    It actually started with a paper jam, as inpatient as I was, I just pulled the paper out of the printer without following guidelines, resulting into the smudging problem.
    Tried to file them a little, sandpaper them to finish. After putting everything back into place, it seemed a little better, but there were still smudges. Now I tried to keep the cover of the photoconducter unit out of the printer, and problem is solved. Now the question is, is this actually good for the photoconductor ? Maybe dust can settle or just ruin the unit alltogether ? Thanks for the great answers btw, have been looking for a solution for a long time.

Had the same problem.

Smudges on the page in vertical lines down page, but mainly in the last few centimeters.

As it got worse they were at multiples of 2cm across the page.

Opened up the photocunductor unit, to find a lattice of reinforcing on the underside. At the intersections were small round pieces that are obviously supposed to be trimmed off, but some were raised and polished by the paper. I removed these and the printing was a lot better. Some lines remained, so I then sanded the whole of the underside of the cover tomake sure I had got everything. Still a few lines appeared, at which point I noticed that the cover was actually curved down, so the best solution would be to strengthen it so that it would stay straight and away from the paper.

I checked that there was enough clearance inside the machine, and then glued a piece of wood to the top of the cover near the raised section. I allowed the glue to dry completely before refitting the unit, as I did not know if the fumes may affect the printer.

Problem solved 100%, for a few pence, using readily available household items.

General tip for cleaning.
Open front cover,
Pull out grey lever/rod on right hand side (comes out about 2 inches)
Externally on right hand side, remove small cover/trap door
Reach inside and pull out cleaning rod till you see white pad
Push in and out about 15 times.
Reinsert rod and lever, close covers.

Press right arrow 3 times to do a status sheet.

Print out a 3 page Word/Wordpad document with 1 character per page. See result

Open top cover,
Lift up orange lever on right hand side
Pull out Photoconductor unit, turn over so you can see roller
check for scratches, clean excess toner with a tissue
With Photoconductor almost vertical, place both thumbs on rubber edges of roller and roll the roller downwards
Examine belt as it moves on top side of Photoconductor
Look for Silver square and make sure it is clean, clean with tissue.
Put Photoconductor back in

Run status sheet/print page tests.

Hope this helps

Just open the topcover off the photoconductor and sandpaper the inside off the cover with a sandpapermachine and make it 2mm tinner and place the cover back but dont put in the screws.just a little peace of ducktape on the sides so you can still lift the conductor out

solved the problem 100% for me

Now in dutch for the people who did not understand the english.

open de boven kant van de photounit je hoeft alleen de buitenste schroefjes te verwijderen en die 2 die naast het handvat zitten
dan schuur je met een schuurmachine met al te grof papier de binnenkant van de kap op tot er 2 mm vanaf is, dan zet je de kap er weer op en gebruikt de schroefjes niet meer, gewoon 2 kleine stukjes ducktape om de kap op ze plaats te houden en om m er weer uit te kunnen tillen,als dat ding zit zit ie dus waarom vastmaken

Ok... for all that had a problem understanding the post. This is what I did.
switch off the printer,
open top cover and lift the yellow leaver to release the photoconductor.
stay in a darkish environment (not too much light) and remove the photoconductor using the yellow handle and place it on the table in front of you.

There a top cover on the photoconductor. Remove the two screws on the sides of the yellow handle. Then there are three screws on each side of the unit holding this cover. Only remove the one screw at the front and one at the back (not the one in the middle - see post from Kps above)

Then remove this cover and examine the underneath of it. Look for any plastic bits that are sticking up. If they are, use a metal file or dremel or a sharp stanley knife to cut them back to the height of the rest of the cover.

Then make sure you dont leave any plastic bits in the cover and replace everything back to normal.

When replacing the cover try and keep the cover lifted when you screw in the bolts to give the cover maximum chance of staying away from the liner underneath.

For me this did impove the print but didnt fix it all together. I will try again soon and this time re-drill the cover holes or something so the cover stays away from the liner underneath.

I just removed the cover totally.
I think it static that pulls the cover down onto the belt.

removing proved the issue and I don't really think it does anything except remove prying hands

Thanks for sharing.  Had spent ages trying to sort that out.

When taking the top cover off the photoconductor unit you do not need to remove the middle screw along the side (holds a roller in place), only the ones at each end and those on top either side of the yellow handle.

And found printing a solid colour page the easiest way to check if I had filed everything correctly.

I had the same problem. It only did it on colours. Black was fine. The smudging was really bad, not just odd spots.

Cleaning and filing didn't help, in fact it got a bit worse. But I could see that the top cover was curved slightly in towards the rubber belt, possibly even touching it. So I removed the front 2 screws (the ones that hold the top cover against where the rubber belt is exposed) and pinged the edge of the cover out from its mounting.

The is now a good few mm gap between the edge of the cover and the rubber belt and the printing has gone back to being perfect.

I think the problem is caused by heat gradually warping the top cover. Since I did the above "fix" I've had no problems whatsoever.

I tried this solution and while I did get an improvement I was still getting odd white specks and small stripes in a repeating pattern that ocurred twice per sheet. For me, the stripes, which were vertical and about 1cm long, occurred about 5cm from the top of the sheet and again at a position about 3 cm up from the bottom.

The fix - I just did the above (there were indeed sticky-out bits, and they had clearly been scraping a bit of toner) and went a stage further. I left the two "front" screws out completely, this left a gap across the full width of about 1mm between the cover and the belt underneath. Print quality is now A++.

I THINK that the photoconductor is actually only the blue/green cylinder on the underside, the black belt that this problem pertains to is a transfer belt so the paper need not touch the transfer roller itself - I know this used to kill photocopiers if cheap paper was used.

If this just started after you replaced the toner cartridge, one would have to say that it is a bad toner cartridge.
Print something that smudges. Pull down the front cover and look at the cartridges. Pay attention to the top one(black).
Look at the drum on that cartridge. You should see the toner sitting there. Compare it to the other cartridges which should be clean.

Lexmark c532n prints smudges on page

The problem could be caused by the photoconductor units. Try to swap the affected photoconductor units (like swap the magenta with black and cyan with yellow). If problem still occurs, then the photoconductors need replacement. I suggest you contact Lexmark Technical Support for assistance. Thanks

When i print in color there are 2-3 smudges (ab. 2 x 1 cm)at the same place evry time. When printin b&w there is no problem.

that only means that the nozzles of your printer for the colored ink are clogged by dried inks but for black, its not, you can try printing a nozzle check to prove or check that. and if you found out that it has missing lines, do head cleaning

4 - black ink smudges (1/32" wide x 1/16" high) in right margin

Very nice trouble shooting. The image defect you describe point to the OPC or drum unit this is essentially the toner cart. In your case black. Measureing the distance between repetitive defects is a sure way of diagnosing problems such as yours. Again nice work.

Google repetitive defect ruler for your model to help in the future.

Hope this helps

Lexmark C522 color printer has black smudges on copies.

It's more than likely a scratch on the photoconductor unit. I had to replace one last week. If you have a spare, try to replace it to confirm.
