This answer was rated:

I have been running my Canon MP240 Printer successfully on Windows 10 up to now on my laptop. Now I cannot print and a window with error message 5100 has appeared , and the Printer alternates between a '2' and a 'P' on its display.
How can I get going again. please?

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question. That is the P-2 error. It means that the ink cartridges and/or their carrier are stuck. This may be caused by a piece of paper jammed in the area of the interior, blocking the movement of the carriage that the ink cartridges are held within. Open the printer, and examine the interior for any paper jam or loose parts or paper scraps. Remove any found, gently and carefully.Some also say this error can require re-seating the ink cartridges... if it comes to doing that, do the re-seating (i.e. removal of a cartridge, then pausing a moment, then putting it back into its place firmly) one cartridge at a time, and do not touch the inky underside nor the electrical contacts on one side.

Hi, Russell.I have done as you suggested but there was no paper block. I have re-seated the cartridges, still with no success. I have a nasty feeling that this might mean the machine has died. The carriage fails to stir when I switch on or switch off whatever place it is on the track. Do you have any other suggestions or am I looking to buy a new printer?
I'm sorry to hear that. How old is the printer?

I suspect the printer is around 10 years old, so I guess I've had my money's worth! As it has been perfect up to this point, I'm loathe to scrap it, but the time has come. Thank you for your help. I'll now 'rate the expert' as requested.
Thank you for the favorable rating.10 years is a very long time for an inkjet printer to last. You got a printer that you either treated very well and carefully in a very good environment for it (cool no doubt, I would guess), or that was unusually fortunate and skilled in its parts and manufacture.But, time does tell. And, if it has a lot of dust inside, that can count too. Some would advise cleaning the 'encoder strip', in case it is clogged with dust, moving the carriage over by hand, and cleaning the other part of the encoder strip too where the carriage was during the first cleaning. But this only applies if there's dust inside your printer. After 10 years, there might be. If you want to try that, let me know. Otherwise, good luck with the new printer, and thanks again.
