SET UP Cartridges for a used 7100

[pattraub]

As with others, I have purchased a refurbished 7155 to replace my older 7155 that I must have been using for more then ten years. The set up is demanding the SET UP cartridges, which, of course, are long gone. I have tried to reset and partial reset without success. The other answers appear to involve some secret process that is only sent privately. Thank you.

Hit Home button, then Back button twice, then Home button (nothing changes on the screen so you just got to go with it.

Open the lid, take out both cartridges and close it. It should error saying "no cartridges found" or something of the like. Open the lid and put the cartridges back in and close the lid. Printer will run diagnostics and print a test page if it worked right

This is not for 7155 but you can see what is done

This bypass works with

HP Officejet 6978, 6962, 6968, 6950
Officejet Pro 6830
HP PageWide 57750dw, 57750, 477dw,
HP OfficeJet Pro 7740
HP OfficeJet Pro 8035, 9010, 9015 8025

Let me know if it works and if you had to make a change in the procedure so I can update my list.
