Sadly not. The cartridge error will have to be resolved before you can use the scanner/fax. You do not however have to have a full cartridge installed, the printer just needs to be able to recognise the cartridge.

U051 indicates an ink cartridge that cannot be recognised by the printer. Sadly you cannot use your printer while this error remains.I would advise the following:-Remove the problem cartridge from the printer-Wipe the gold contacts on the front of the cartridge with a piece of non fibrous tissue (like kitchen tissue).-Re-install the cartridge.If the error remains it is likely that there is a genuine problem with the cartridge. So I would advise re-installing whichever cartridge you had in the printer before the error began to show or purchasing a new ink cartridge.

got a repair shop. some items only should be fixed by a qualified dealer cause not everything is fixable. OR buy a new one.

maybe the ink hasn't become flowable. Might take up to 24 hrs to free flow

Yes. The printer has to have all ink cartridges working in order to print.

Forcing a piece of cardstock as far into the feed as I could, then removing it fixed this problem for me.
