    How do you do this (disassemble the printer remove and re-align the carousel)? Are there step by step instructions for a novice? Thanks!

The printer has to be almost completely disassembled, carousel removed and re-aligned. This solves about 90% of time.

MY HP 2840 IS ONLY PRINTING ON THR RIGHT SIDE, What could be the problem?


this is a typical problem.. this printer uses a carasol meaning that the toners are riding on a carasol there are 2 white gears that drive the carasol 1 on the right and one on the left. Half page fade is almost always a misaligned carousel! A Tech is needed or a service manual here is a link for the manual http://www.partshere.com/Models/Q3948A/CLJ_2820_Removal_replacement.pdf
look at figure 5-78 Removing the print-cartridge carousel you will see the white gears im talking about

The color is faded on the left side of the page printer, what is the possible cause or solution?


From the service manual:

If the light printing is on the left side of the page, the carousel might be dislocated.

Solution: Verify that the print-cartridge carousel drive teeth are aligned correctly. If the teeth are aligned correctly, replace the print-cartridge carousel.
