Hi
Error 1203 Dell 962
There can only try and I hope it will do the job for you.

Error 1203 is an issue that occurs either when a cartridge is bad or the printer cartridge Slot is bad...

1 - try cleaning the copper contacts of the both carts and cart slot in the printer and try again..
or
2 - when error shows up, shut the printers power off; wait one minute and turn it back on press copy

you may need to Reset Factory Defaults

This is a error code which is seen in Lexmark Printers which remarks that the Printer's one Printer Head has a short circuit. This issue is a difficult-fixing issue, try to contact Lexmark, they will replace it. But before contacting them, try the Following steps, it may solve the issue:----

1. First, get the All-In-One off.
2. Then get the AIO unplugged from the Wall.
3. Then after 5 min, Plug-in the AIO.
4. Then at last, Re-install the Cartridges.

Try this, if not working, kindly contact Lexmark.
Thank you Sir, Have a nice day.

Thank you

These steps are for a Lexmark 4200, but I suspect they will work for your printer as well:

Cartridge Error: 1203

Your print cartridge has a short.

1. Press Power to turn your All-In-One off.
2. Unplug your All-In-One from the wall outlet.
3. Plug in your All-In-One.
4. Reinstall the cartridges.

If this does not resolve the problem, see More troubleshooting options, or replace your cartridges.
