My new HP 678 black cartridges are now not compatible to Deskjet 3545. Why?

Welcome to the HP Support Community

Let us try these steps:

I suggest you do a Hard Reset on the printer

(1) Turn the printer on, if it is not already on.

(2) Wait until the printer is idle and silent before you continue.

(3) With the printer turned on, disconnect the power cord from the rear of the printer.

(4) Unplug the power cord from the wall outlet.

(5) Wait at least 60 seconds.

(6) Plug the power cord back into the wall outlet.

NOTE: HP recommends connecting the printer power cord directly to the wall outlet.

(7) Reconnect the power cord to the rear of the printer.

(8) 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.

Then update the printer’s firmware by following instructions from this link: https://support.hp.com/in-en/product/hp-deskjet-ink-advantage-3540-e-all-in-one-printer-series/52859...

Restart the printer.

If the issue persists, then perform all the prescribed steps from this link: https://support.hp.com/in-en/product/hp-deskjet-ink-advantage-3540-e-all-in-one-printer-series/52859...  for Cartridge Missing or Incompatible Ink Cartridges Error Displays.

• Perform these steps:  "Step 1: Make sure the cartridges are compatible" to "Step 9: Replace the cartridge"
