Sounds like the cyan photoconductor unit needs to be replaced. Usually what ever the color dot is that photoconductor has a pinhole in it and the only to get rid of it is to replace it.

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.

When printing the sheet of paper has 3 dots on the


Yes this could be the drum.

You could remove the drum and carefully look for the pattern of dots etc that you are getting on the page but on the drum surface.

I would suggest replacing the drum 1st and retrying.

If the black lines are just down one edge then the fuser could be to blame for the black marks but without being able to see the page i cant tell. The drum is certainly my 1st suspect and is easy for you to try.

Ink dots on right side of paper


Toner cartridge? So this is a laser printer? In that case I suspect it is not new? This sounds like old age on the main image drum, that will probably give the exact same mark on each page, correct?

Solution for "I have a Epson Aculaser c1100 and four coloured dots have appeared when printing. These dots are approximately 5cms from the left side of the page and print in a small vertical group. Each...


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).

Red dots on left of page


You need to measure the distance between two dots (In milimeters if possible). After that I may be able to determine what is causing the problem.
