From what i know, some printers have a memory ram disk that holds the information for printing.
go to applications folder for your computer, dbl click printer icon for make of printer. check settings. print 'test document and clean cartridge heads', this should ensure proper printing formats. also see if there is information in this icon settings page about memory settings.

lastly, go to web site of printer model and check site for trouble shooting if this does not work above.
hope this helps and good luck

My canon pixma mp495 printer keeps sayig papaer jam and pulls the paper in on one side only

There may be a bit of paper or a foreign object (paper clip, staple) stuck in the feeder rollers inside the printer. Lift and open every panel that you can and have a good look with a torch. pick out any foreign material you find.

Recognize ink cartridges

Are the cartridges the same as recommended by OEM? If not, the printer will not recognize it.
Switch off, check if printer still your default. Do a test. If no luck, go to tools and clean and align cartridges. GL

My Camera keeps sayig lens error, what does that mean???

Unfortunately, many cameras that fall prey to lens error problems can only be corrected by professional repair. But, here are some last resort troubleshooting steps that you can try that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try.

Paper jammed but sheet came out with corner shredded...assume piece(s) stuck in printer but cannot see it...followed manual's trouble-shooting guide but printer will not print...keeps showing error code...

If you aren't willing to disassemble the printer, and you are unable to see the missing pieces of paper, you will need to have the unit serviced or buy a new one.
If it's under warranty, don't say anything about the shredded paper, just tell them that it started with this error code one day, and you have no clue what's wrong.

If you have more then one stick of memory in that printer then try putting one stick of memory in one slot then the other and turn on the printer after each stick reinsertion.

If you still get the error message then try the other memory stick and repeat the process to see if the error message still appears, sounds like a memory problem to me.

If you have other memory you can test in there, I would suggest that.

If you try new memory and the printer can cycle thru the RAM test then you know that the ram you have is bad.

If you try new memory but the system is still failing the ram check then you know its a system board problem.

Im having an error sayig SC:542 so how can i solve this kid of problem?

This is a 'fuser" warm up error. You could have a blown out heater lamp, or fuse, but most often this is caused by a power fluctuation. The reset for this is done by simply entering the service mode, and turning the machine of/on with the main power (red button).
enter service mode as follows:
"Clear Modes"
" 1, 0, 7 "
then hold "Clear/Stop" for 2-3 seconds.
The display will change with "service mode" in the top corner.
Now turn power off/ on (red switch)
** Never go further into the service mode, as you can cause all kinds of difficulty.
If the code comes back, then you will have to get a technician on site to troubleshoot the fuser.

Please rate me :)
