when i hit print in black on my 5740 printer, it prints in color.

when I want to make a black copy, I hit black and my printer prints in color. I cannot make a black and white copy. I can print off computer in black, but not to make a copy, so my cartridges are fine, I think.

Welcome to HP Support Community

I would like to help

Please try these steps

- Turn on the printer.
- Wait until the printer is idle and silent before you continue.
- Disconnect the USB cable from the rear of the printer. If your printer has a network or wireless connection, leave it connected.
- Remove the ink cartridges from the printer and clean the electrical contacts with a lint free cloth
- With the printer turned on, disconnect the power cord from the rear of the printer and from the wall outlet or power strip.
- Wait at least 60 seconds.
- Plug the power cord back into the wall outlet.
NOTE: HP recommends connecting the printer power cord directly to a wall outlet.
- Reconnect the power cord to the rear of the printer.
- Turn on the printer, if it does not automatically turn on.
- The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
- Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
- Reinsert the ink cartridges, and then close the ink cartridge access door.
- If you receive a prompt to print a calibration page, do so.
 

Also ensure the printer has the latest Firmware https://support.hp.com/in-en/document/c02919168
