Have a look at this link

"Delete the INFCACHE" has worked for me in the past.

Also I found that I was using a non USB 2.0 cable which caused the "unrecognized USB" problem. Once I used a proper USB 2.0 cable it was fine.

Hope that helps.

My printer prints blank pages when I want to print files from my computer, but works fine without a computer


If you don't use the printer often (at least once a month) you probably have cartridges drying up on you. If by chance you have an Epson or canon, the print head is inside the printer, so regardless of how many new cartridges you put in there, you will encounter the same problem.

If you are using a generic or third party ink, it may be too dense or of low quality clogging yourprint head.

You can try to run a bunch of print head cleanings. (your manual will tell you how) If by about 8 you are not seeing any improvement start with a new printer. Do a print head cleaning once a month ALWAYS as a preventative measure. This will ensure you get a long life out of your printer, and a top quality print from your cartridges.

My Canon MP240 suddenly began printing streaky lines at regular intervals on the page. In between the print is good. I have done all maintenance functions without success. I think perhaps the roller may be...


Try Pulling the print head out and cleaning it manually
  1. First remove the cartridge
  2. lift the orange or green lever on the side of the cartridge holder and pull the print head out.
  3. Fill a saucer with boiling water, about 2mm deep
  4. Place the head in the boiling water and leave for about 2 mins. Dry before replacing in printer
  5. While the head is out have a look in the printer for any excess ink on the rollers or where the cartridge head "rests". Clean with tissue paper if needed.
  6. Re-assemble the printer, replace the head and cartridges and test.
I hope this helps

Possible solutions:
* Try restarting your PC.
* Hook-up the USB connector to the original USB port... If unplugged.
* When you print choose the latest printer detected... copy 1 or copy 2
* Delete the printer and re-plug the USB port.
* Defective USB cable, try other cables.

attempt to remove and reconnect the USB cable to both the computer and printer, reinstall your printer driver, and then make sure your printer settings is set to use your correct printer. you may also try to print a test page to confirm that the printer is still working.

Service error 5200 canon mp240


Sir,
Error 5200 indicated an error with the print head. Try to cleaning all contacts on the print head as well as on the connecting pad. And also the power needs to be restated, so do it and try it again, just take out the USB, the power from the wall outlet and the USB in the printer itself.
Thanks Good Luck
