turn off the printer.
pull out the black ink cartridge and reseat it. make sure there is no shipping tape attached and it "click" in the carrier.

without the port you cant connect

Try getting the printer to re-initialize itself, also make sure that the copper contacts on the cartridge and printhead are clean.
You may be able to fix this issue by unplugging the unit while it is on and holding the # and 6 while plugging the unit back in (semi full NVM reset)

All over the web the concensus seems to be disassembly and cleaning bulb, mirros and/or the glass and a calibration strip. Mine has the same error, and I'm gonna try the cleaning those locations. This forum mentioned a disassembly procedure for the D145, I hope it's the same for the 7100 series (7140XI) I'll post back my success.

Could be a bad pickup roller.
