I found this on another Forum. It is for the HP2600 and may well work for HP1600. It may or may not work. It is quoted in full:-

"I did a google on 2600n and chip reset and I found out that we can set-up the printer to print past its 2000 and 2500 page limit. Below are the instructions I got.

Cartridge Out Override can only be enabled from the printers control panel menu.
1. From the main menu, press (RIGHT ARROW) to System set-up and press (SELECT).
2. Press (RIGHT ARROW) to Print quality and press (SELECT).
3. Press (RIGHT ARROW) to Replace supplies and press (SELECT).
4. Press (RIGHT ARROW) to Override out and press (SELECT).
5. Press (SELECT). If Stop at out is selected, the printer will stop printing when a cartridge reaches the recommended replacement point. If Override out is selected, the printer will continue printing when a cartridge reaches the recommended replacement point. The factory default setting is Stop at out."

There is also a guide on eBay for resetting the chip in a similar manner.

Hope this helps, but the general consensus seems tobe to replace the chip at every refill. Has anyone else tried this or made any observations? Cheers.
