Brother printer unusable print quality
I have a brother MFC-J5910DW with refillable cartridges.
This morning I printed a minnie mouse graphic with no problems at all and created a jigsaw from it.
Then I tried to print a photograph for a keyring and the quality was terrible. I was advised to clean the print heads so I did this twice. The first attempt the yellows showed up slightly off and the second time a bit worse and then after that there were large sections of the print quality report missing because the printing was so bad. Brother told me to do the cleaning up to 6 times but each time it got worse.
So this afternoon I bought the printer back to the shop and they gave me a new one. I have just gotten home and plugged the new printer in, put in my refillable cartridges and printed the test sheet and it is the exact same as the old printer, completely unusable quality, barely printing text at all.
If this is a brand new printer its leading me to believe that there is a problem with the ink but I have no idea what or how to fix it. Any suggestions would be very very very much appreciated.
