Red dots on left of page

Whenever I print in colour I get a series of evenly spaced red dots all down the left side of the page. It doesn't happen when I pring in black. I have removed and cleaned all cartridges and the parts of the printer I can get to.

The dots do not look like residue from ink on a roller etc but look like small commas (,) and the density of the printing is the same on each dot (no fade).

Any ideas would be appreciated.

Re: 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.

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.

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.

We have just changed the photoconductor unit on our Epson Aculaser CX11NF printer. When we print or copy, we get coloured spots on the right hand side of the page

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.

11 blue dots print out down the left hand side of documents

It's probably the toner cartridge again. See if you can spot defects at the cyan drum unit that matches the marks on your printout.

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).
