Hi there and welcome to Just Answer, my name is ***** ***** I look forward to helping you.

I’m sorry to hear you're having trouble. I know that can be frustrating. Hopefully, we can get this resolved quickly.
Can you remove the ink from the printer then power it off.
then using a Q-Tip with cleaning alcohol (or warm water if you do not have any), clean out the areas where the ink goes in.
Then use a damp cloth and wipe down the inside of the printer.
Once done, let it dry for 10 minutes
Then put the ink back in, power it on and tell me if it then prints correctly please
This will also allow you to see if any foreign objects are in the printer which may cause this.

I'm afraid the same B203 error has come up

Thanks but don't bother, I did not realise there was £16 charge for a phone call. I will buy a new printer
Expert:  Richard replied 1 year ago.

Can you please do the following

  • Turn off the printer
  • Open the cover
  • Turn on the printer
  • Wait for print carriage to start moving to the left and let it go past half way
  • Before print carriage reaches left hand side (but after going halfway across) shut the cover.
  • Leave the Printer turned on.

Tell me if it clears it please
