Question about Epson Office Equipment & Supplies
Pages are black all over and dirty on reverse side
When a color printer prints all black, it means the printer is putting either just black on the page, or all colors which appear black. The first step is to figure out if it's just black, or all colors. You can print a half page by opening the printer during a print. Then look at the page to see if there is any color in it. Try rubbing some of the toner across the page to reveal colors.
If the problem is black only, then try replacing the black cartridge. If the black toner doesn't fix it, then it may the the black laser or control module.
The all colors are on the page, then you probably have a bad control module.

The paper tracking on the epson is not perfect. You may also notice that the paper can skew off / twist as it goes through, especially if printing on the rear side. Try printing a box aligned with all margins and you'll notice that it doesn't align with the paper edges.
a) The specific issue that you speak about can be compensated for in the "extended" settings on the prinproperties. You can "Offset the print" by a mm or so to adjust slight inconsistencies and get, for example two text frames to print back to back, lined up.
b) When printing the reverse side of paper, use in the general properties tab, paper type, "plain (back)". The printer then seems to compensate a bit for the fact that the now heated and curled paper needs to move through the mechanism.

SOURCE: Solution for
The four coloured dots are what is known in the trade as "Traffic Lights". They happen when the photocuductor (PCU) drum gets scratched. If you do a black only print you will only get a black dot, if you do a print with some colour in it you will get all four dots repeated at 150.41mm (PCU drum circumference) intervals. The best answer would be to replace the PCU but it is expensive. The alternative is to take out the PCU, find the scratch and try to polish it out with a very soft cloth. This will only work on the lightest of scratches. Be very careful not to scratch the drum further and avoid shining any bright light on it as it will damage the photo-sensitive surface (normal ambient light is OK).

Oh-ho! The coloured spots are what is known as "traffic lights". To be sure these are the symptoms: You will have a black spot then a slightly larger gap then the three colours regularly spaced, the pattern will repeat every 150mm or so. If you print a black only page then only the black dot will appear, print with any colours and all four dots will be printed. It is caused by a tiny/slight scratch on the photoconductor (PCU) drum (usually caused by mishandling, a loose or foreign object inside the printer or even trying to print on stapled paper!). Polishing the drum using a very soft dry cloth can often help to get rid of the scratch, but remember to keep it away from any bright light as this will damage the sensitivity of the drum. The traffic lights will be in line with the scratch so concentrate your efforts in that area. Also, while the PCU is out, take a good look inside the printer for any loose or protruding objects, rotate the toner cartridges from above with the front cover closed (opening the front locks the cartridge carousel in position). I sincerely hope this helps as the only other remedy is to replace the PCU with a new one.

Two things to check,
1- clean the laser by opening the front cover, pull forward the green lever on the R/H side, take off the little panel on the R/H side of the printer and pull out/push in the lens cleaning "stick". Replace panel and push the lever back in, close the front and try a test print.
If that didn't work:
2- Open the lid, lift the orange lever and remove the photoconductor. Be careful with it as it is easily scratched. Inside the printer rotate the toner cartridges and check that the cartridge lock levers are fully locked as even a couple of millimeters can block the laser.
Hope this helps.
