HP PSC 1610 Error

I have discovered how to perform a full reset of the HP PSC 1610, which clears all the internal memory, thereby fixing the "remove and check right cartridge" problem.

To perform a full reset of the HP PSC 1610:
1. Unplug the power cord.
2. Press and hold the OK and CANCEL buttons on the front panel keypad.
3. While still holding the buttons, plug the power cord back in. Continue to hold the buttons for two seconds, and then release them.
4. After a few seconds, the screen will display the message “Deriv Clear” confirming that the reset is done.



I have discovered that the HP PSC 1610 all-in-one printer has a hidden diagnostic mode, which lets you do several interesting things.

To enter the hidden diagnostic mode of the HP PSC 1610:
1. tap both arrow keys simultaneously.
2. tap the left arrow key.
3. tap the OK key.
4. At this point, you have a choice to make. If you want to enter the "Service" menu, tap the left arrow key. If, on the other hand, you want to get into the "Underware" menu, tap the right arrow key.

There is a menu option in the "Underware" menu called "printer-mech button tap", from which you can initiate any of HP's "tap tests," so called because, on the early HP printers whose onboard user interface was limited to two physical buttons, you would tell the printer which diagnostic test you wanted it to perform by holding down one of the buttons while tapping the other button a certain number of times. In the HP literature, the various diagnostic tests that the printer can do are named according to the number of button taps required to initiate the test. Hence, HP might refer to "tap test #6", "tap test #9", and so forth.
I am not sure what all of the various tap tests do, but I would imagine there is probably a tap test that resets the internal counter responsible for making the printer reject the cartridges.
