Can smears when priting be fixed

When printing there are three dots on the left hand side of the paper and now there has been black smears with each print. I changed the printer cartridge to see if that would help, There are still dots and the smears are more consistent. How can this be fixed?

    I also have the three dots showing up on the right hand side, but no smearing. It's frustrating when I have to print out legal letters!

    I also have a similar problem. I show lines on the left side of the paper when printing. I purchased and installed this today. I have tried printing several times.

Have you tried cleaning the corona wire on the drum unit (the blue slider bit)?

Replace the drum unit (assuming you have already replaced the toner cart?)

To check the remaining drum life press the go button 3 times. A report should print out with the info on. Even though you may have some remaining life, the drum can fail early.

If the dots/marks are repeating about 3 times down the page it is almost certainly the drum unit that has the problem.

Black dots are printing on the left hand side of the page when I print from my hp laserjet 1015. Any ideas how to fix this?


Run a "half test". Put paper in the manual feed tray. Print anything. Watch the paper, when it feeds about 1/2 way into the printer, open the cover. Pull out the toner and look down at the paper. If it has the dots, replace the toner. If it doesn't have dots, the fuser is probably bad.

The printer is printing little black dots on my documents


If the dots are all over the paper you may need to replace your toner cartridge. If the dots are smearing, you may need to check your fuser assembly (have it checked by a professional).

4 colour dots on printout but not 150mm apart


Measure the distance between two of the same coloured dots down the page, if it is just over 150mm then it is caused by scratches on the photoconductor drum (this is the only thing that has a 15.4mm circumference). Try printing a black and white only document, only the black dots should appear. Removing the photoconductor and gently polishing the blue drum with a soft cloth can help if the scratches are not too deep, otherwise a new photoconductor is the only route.

It prints three dots on the left side of the page every time.


These dots may be called as "Garbage Valley"
This means ur printer has got lots to print but it was stopped due to certain reason.
I'll ask u to go through ur printer manual & print atleast 5 pages of garbage valley & while u do this, i'll ask u to reinstall ur printer driver.
Hope it works out.
Thanks

Black ink smears everything.


you may have to clean the print head. since the jam cause the smear, and there still have some ink left on the print head.
you wouldn't get aclean copy till all of the ink trace are gone.

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

Colors faded on left side of paper black and blue


Is it possible for you to clean the printheads manually with cotton buds and cleaning solution on this unit. Clean all thoroughly and this might just correct issue.
