Question about HP LaserJet 2840 Printer
Only printing black copies, whey is that?
can only print in black
Try a "hard restart", which simply means unplugging the power cord of the printer, and replugging it after one minute has passed. If that does not work, then rerun the CD used to install the printer. Both techniques reprogram the electronics, to a certain extent.
You also might visit the manufacturer's website, to see what solutions are being offered for printer problems. They probably have a number to call, in case you need to talk to a technician.
Hope these suggestions help you out.
