11 blue dots print out down the left hand side of documents
I've just installed an HP Colour LaserJet CP2025 dn printer.
Every time I print 11 blue dots, evenly spaced, appear down the left hand of the margin of the document.
How do I stop this happening please?

Very few printers will print if they're out of toner, even if the colour toner is exhausted and the print job is only black. Replace the empty toner and if this is the only problem, the printer will continue printing.
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.
dots printed are from the cartridge, you proved that with the change to the old one. If the fuser was faulty, it would repeat the dot 2.5 times down an 8.5 x 11 page
Replace the cartridge and please use HP , remanufactured cartridges fail prematurley and usually wind up costnig more in service and repair/exchanges.
You will most likely need to change what ever toner cartridge that is the same color as the dots. So if the dots are pink change the magenta. If they are blue change the cyan. Most of the time these dots are a result of the toner cartridges drum having a pit or similar defect in it. Changing the toner cartridge will take care of this.
Good Luck and Thank You for using Fixya.
1515n - I have the Magenta colour 'shadowing' the blue test. A mirror image of the blue text. [slightly staggered] Black is fine. Applies to all Word docs when printing in blue - can you help please? I only use genuine cartridges. Thanks Jules Radstock

Talked to HP support and fixed mine by changing Settings/Paper Handling/Tray 2 Type to "Heavy 111-130g"
All paper handling settings as follows:

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.
