How to Clean Clogged Printer Heads

wipe out print head connection point with arosel and instal head again

Inkjet printers need to be used frequently to prevent inkdrying out in the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages,then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer thanreplace the print head.

Hi as you have cleaned the heads the next step is to replace the print heads or some people claim that cleaning the heads with some expensive liquid works I have not had any luck with this.
so I would suggest you look up Canon PIXMA MX330 print head, on Amazon at about £47. so not cheep but very simple to fit
good luck

UO52 error is either a print head temp sensor error or faulty EEPROM data from the print head. You need to re-set the print head. If that fails then a new print head is required.
