My HP Color LaserJet CP1515n prints perfectly in black and white. But the Color cartidges dont seem to be aligned property. I have done a calibrate color test, and I have done a diagnostics test - this test shows the left hand side of the page ot aligning properly (the L shape in the right hand corner does not align) Please help

SOURCE: align cartridge

Click 'Start' then 'Settings' then 'Printers and faxes' Right click on the printer in the list and select 'Properties' from the pop-up menu. Somewhere on the resulting dialog there will be a button labeled something like 'align' or 'calibrate'. Click this, you will need paper in the printer when you do this.

You are lucky you can print ANYTHING! My unit has NEVER worked (3 years) due to a hardware defect of HP. I downloaded patches, cleaned/replaced cartridges, etc.
Spoke to HP last nite-Was told printer was junk-they don't carry it or any parts to fix it anymore!! I was told to replace it!

Here was the solution. You MUST use HP brand black cartridge. Originally I purchased a #94 Office Max brand black cartridge. After it did not work I took it back and they gave me a second Office Max brand and that did not work either. So I took it back and they sold me an HP brand (I only needed to pay the difference in price so Office Max was good to work with). I installed the HP #94 black cartridge and everything now works.

I own a HP 2600n and I had the same problem the way I fixed it was hold both arrow buttons in the turned off the power for 10 seconds while holding the buttons in then turned it back on then released after 3seconds the reset my defaults this cured my problems
