Yes it says 'Unable to clean' on the printer display, as well as the instructions to carry out routine maintenance
It should be pointed out there are some variances of the button names which can include:
To get started turn the machine on and wait for it to start up.
The printer should now reset and the level of ink recorded as being present in the waste ink sponge should be reset back to zero. Any errors relating to ‘Unable to Clean’ or ‘Error 46’ should have disappeared and the printer should function as normal.
Thank you for your help. I will try that tomorrow, too tired now. Will let you know how I get on.
