Over a week ago my boss had her printer (HP 2550Ln) suddenly stop working. I checked the warning light an it was the Imaging drum that needed replacing. I looked around and did some research and got to the approximate price of £ 90-something for a replacement. Well I looked at the last page printed on that printer and the quality was very good, actually it was as good as when the printer first arrived so I went to the HP website where I read about the Imaging Drum and how it works, interesting way of making money out of costumers.
The printer’s Imaging drum has a built in counter so after a X number of copies it stops working and needs to be replaced even if the quality is still great.
After looking around for a bit on the internet I found a site which gave me very simple instructions on how to reset a HP Imaging Drum for the models Laserjet 2550 2550L 2550Ln.
I did it and it worked, the printer is printing away with great quality. Please remember this is just a tip, do it at your own risk.

I’ve tried all of these reset methods to no avail. Finally I tried swapping chips from the Imaging Drum & one of the colour toner cartridges and presto…IT WORKED! The chips are easy to switch. Just pry them off carefully as they are only held in place by strong double-sided tape. I shut off my printer. Swapped the chips from the Imaging Drum & the Magenta, that happened to be the one showing, and it works fine. I used a small flat screwdriver to pry off the chips. Working them off from end to end. The chip has a notch so it will only go back in one way….EASY AS CAKE…..Okay….lol…pie! Seriously, not a joke this really did work. Maybe the printer sees the swapped chips as generic replacements.
