The error B204 could happen after a cartridge replacement.
First of all, when installing, remove the cartridges from the plastic package, but do not drill any plastic membranes, as this will cause this error when placing the cartridge.
The error may also appear if you change a completely empty cartridge: when installing a full cartridge, the printer enters a cleaning cycle, but the printhead has not yet received ink from the newly inserted cartridge.
Here are some tips to cancel this error B204::
Remove the cartridges Power the printer for 2 minutes Switch on the printer Install the cartrdiges
Switch on the printer Unplug the power cable Open the cover Move the print head carriage manually to the usual place where it goes for the cartridge change (If the printhead carriage is not movable, reconnect and then turn on the printer, then unplug it again when the head carriage is in the moving position). Change the cartridges. Close the front cover of the printer, plug in the power cord, and restart the printer for normal use.
