Since my MP530 has died with the message UO52 and I have tried all your tips suggested on the forum

I suppose the cost of repair would be foolish due to the age of this printer. Sad that I have 10 ink cartridges for this machine. I see from the discussions that this is a very common fault with little or no resolution. I will be shopping for a different brand.

Hi mikey1944,

To try and resolve the error, please remove and reseat the ink tanks and print head in the unit.  Next, please turn off the printer, unplug the power cord from the back and leave it out for at least 10 minutes, then plug it back in and turn it back on. Should the error persist, the printer will require servicing.  Please call or email us using one of the methods on the Contact Us page to obtain servicing options available to you.
