Printer Reads Full Ink Cartridge as Empty

OfficeJet Pro 8100
Microsoft Windows 7 (64-bit)

My OfficeJet Pro 8100 is not reading the red ink cartridge correctly.  All of the other ink cartridges are working correctly.  I am using genuine HP ink.  The printer shows the red cartridge as empty; when I replace it it will show as full for two page prints, and then show as empty.  I have tried 4 brand new red cartridges, and this happens each time.  Can someone help?  Thanks in advance.

Printer Reads Full Ink Cartridge as Empty

Hi @Cokeologist

Welcome to the HP Support Community. I'd be happy to assist you. Let us try these steps to resolve this issue:


Reset the printer

  1. With the printer turned on, disconnect the power cord from the rear of the printer.
  2. Wait at least 60 seconds.
  3. Reconnect the power cord to the rear of the printer.
  4. Turn ON the printer, if it does not automatically turn on.
  5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.
