Hi
Long time Lurker first time Poster 🙂
I’m working with an HP LaserJet 2550LN, connected through LAN. Drum is about middle age, toner cartridges are about 2 weeks old. Last Thursday the Magneta, Cyan and Yellow lights turned solid and the user could not print. User has a “cannot connect” error from the printer software.
I removed the cartridges, evened out the toner, put them back, and the lights turned solid again as I put them back. I did the only reset function I could find, which was for the drum. I did restarts with everything out of it, with everything in it, with my finger on my nose, nothing worked.
I printed an information page from the printer control panel just fine. Today I am told they can now print, but the lights are still solid!
Anyone ever had this problem? Is there something wrong with the toner chips? Is there a reset function? HP website says it means the toner is low, but it just can’t be after 2 weeks.
