Canon pixma mp272 printer. replaced black cartridge for the first time and now it wont print. getting error p08 on the printer and error 5200 on my laptop screen

Sorry it's too late..error code P08 or 5200 indicates print head temperature error. Please check whether colour cartridge cl811 is empty or the ink is low. This cl811 is so sensitive with high temperature when the ink is low. If the ink is low or empty the you need replace the cartridge. This common problem I find on cl811 cartridge :)

Hello Hellen,
the error P08 is error for abnormal temperature in print head. Aa possible cause the ink cartridge is faulty and needs to be replaced.The same error description is for 5200 on your PC.

I recommend that you try to replace ink cartrigde under warranty in store where you bought it. If after that you still have error, take the printer to the service center because they logic board ( pcb ) is faulty.

Hope that helps!
