My HP Color LaserJet 2840 All in One Prints Blank Pages

[NickW100]

I installed new HP cartridges (Cyan, Magenta, Yellow) and the printer is giving out blank pages.

Sometimes in prints yellow squares

Could someone please help?

Thanks Nick

Your issue is probably the carousel solenoid. Below is a link on how to repair on the HP 2500 color which has the same engine. You need to do a google search for the service manual for the 2840 and follow the instructions to remove the top cover which will put in the position to following the insructions on the HP2500.  Good Luck.

Thanks for the info I will try to do it.

Also when i put back one the old cartridge (used out) it will print in black.

Do i still need to clean the solenoid?

From the control panel menu of the printer print a config report and tell what it looks like or post a sample here.

I did take the printer apart and found the solenoid and there was some sticky residue present.  I removed the sticky residue and place a piece of eletrical tape there.  I put the printer back together but I'm still receiving the same result.  Any ideas?
