What is the cause of the error U051, U052 and B200 in printers Canon

Is not novelty errors printers Canon, but what can you do to avoid them.
These errors will be scheduled to happen at some point, or happen due to certain conditions.
At what point should replace the print head, to prevent the errors appear.
I think it would be good to have some indications to try to avoid this problem.

Hello Jose. You ask an interesting question: What can we look out for or do to prevent certain errors from occurring.

First, I do not think any of these errors are scheduled. I took your meaning to be that Canon pre-plans for these errors to occur purposefully such as to cause us to purchase more stuff from them. I think the error messages are Canon's way to help us and them fix the problem.

Second, I have never heard of people replacing a print head before a true problem occurred first. Print heads are expensive and should be used until they malfunction. This is not to say you should not treat the print head with respect and exercise it like a race horse -- print at least a nozzle check every week or two to keep the nozzles from plugging up with dried ink.

Third, the error messages you list have different causes. Also, not every Canon inkjet has all of these errors possible. For instance, I just looked at my MP830 Service Manual and there is no B200 or U052, so if you run into a problem in the future and ask a question on the forum then make sure to include the make and model of your printer.

The best way to avoid problems is not start one in the first place. I know, easier said than done. However, use your printer regularly and with care and she will provide you as long as she can.

When I spoke to replace the print head, it was not to damage the logic board.
Regarding errors, the idea is to have a set of procedures that can prevent these errors in various printers and not just a printer model.
At this time my printer is an Epson Stylus Photo PX730WD that is with an unsolvable problem to date, http://www.printerknowledge.com/thr...oes-not-recognize-ink-cartridges.10191/page-3
So I am thinking of buying a Canon, as I know that Canon has these mistakes, knowing how to avoid them can prolong the printer's life.

I decided to move my post to where it belongs:

There is nothing special, just usual care and operational attention such as keeping the printer within the operating environment limits as noted in the user manual, paying attention when inserting cartridges into the print head to avoid placing them in the wrong slot, good refilling hygiene to prevent spills or electrical short circuits from fluids in places they should not be, and treating the printer with TLC (including what I already wrote about weekly printing).

Thank you all for your cooperation.
What we have here in the general forum is how to solve the problems that exist and not to prevent them, so I thought it would be nice to have something to prevent.

Thanks
