Our new-ish printer at my office (1 year old ish), just ran out of yellow toner. We bought a new toner cartridge for it and installed it, now it won't print yellow at all. At the same time, bought a black toner cartridge which worked great....not sure what to do.
Were you able to get your printer to print yellow again?
If not, do you know whether the new yellow cartridge was gently shaken before it was installed to loosen up the toner? Sometimes, the toner particles can become packed during transit. The cartridges should be gently shaken before installing them to help loosen up the toner.
