How to fix HP Color LaserJet 2600n Fading Color

Introducción

Over time, the laser toner leaks into the scanning element and can interfere with the printer's ability to produce consistent color. To repair this, we first must disassemble the printer to reach the scanning element, and then clean the optics so the printer produces color as it was meant to.

The first time I did this repair it was with guidance from the pdf attached to the first reply in this thread

    • Before we begin, make sure to unplug the printer and any connected wires. To be extra safe, turn the power switch to 'off.'

    • First, let's establish what part of the printer is what so that we can communicate clearly throughout the guide. The red square is the front and the orange square is the top. After those, we have left (yellow), and right (green). The back is opposite the front and the bottom is opposite the top.

    • Laser printers often have loose toner, a very fine and vibrant powder that will invade everything you don't want it to. I did my disassembly outside

    • Open the front door and remove the toner cartridges.

    • Set the cartridges aside for later. To keep them clean, place them in a bag or closed box.

Takes 2-3 hours to disassemble and reassemble for a first timer but it worked really well!

And in the end all it cost me was my time.

Many thanks!

Jon Rousseau - Contestar

Thank you very much for sharing your knowledge with this guide.

Since I had the machine apart I took the time to clean every area I could get to that is within the paper path.

It took me 6 hrs. to complete the job; but it did not work.

The printer indicated an Error Code 51.21.

So I did the job over again.

I had been fooled by the two ribbons that connect to the optical sub-assembly that by design rub up against the right side of the box, even when disconnected.

My second servicing took me about three hours.

Thank you.

I have a normal working color printer again, and did not have to buy saved the cost of parts and labor by using your guide for restoration.

Hi there - In step # 23, am I missing the right screw or is there really just one Phillips screw with a lock-washer?

R. Douleh - Contestar

R. Douleh- the manufacturer did not put a screw on the right side for some reason.

This really is, without doubt, the best set of do-it-yourself instructions I have seen in my 45+ years working in the IT industry.

I didn't see any dust in the area to be cleaned, so I am a little mystified as to what the cause was. I got the missing magenta colour working but despite running the process twice I could not get yellow to work properly. I only use it for printing letters and spreadsheets, so I can live without that.

Thanks again
