Both lights stay on when printer is switched on, but nothing happens

SOURCE: Canon Pixma MP140

oook --
As a technician, I have worked on tons of printers. This particular error had stumped me for a while, but I finally found the cause. As others had pointed out before, it can have alot to do with some obstruction in the print path, the gears, or ink on the clear plastic encoder strip. You're on the right track - I found the the purge cap (the white sliding mechanism that the print head parks to when it's not in use) was not lubricated well enough from factory. If you lubricate the sliders with some white grease (don't get it on the small wipers or the black caps) the mechanism can now slide more freely, and the unit can park the head properly without giving you the dreaded head homing error 5100 (or E-2-2 on the LCD display) Keep in mind that this repair will probably require you to remove the right panel off of the printer to gain access to the purge mechanism. There are two screws behind the printer, and two in front for each corrosponding side panel (the front screws are behind the grey front panel of the printer - open the top cover to see the clips which hold the front cover on) Hope this helps some of you out.

If the rollers are working, but its not pulling the paper in, I would suggest, as suggested in another thread, to 'rough up' the rollers in an attempt to give them better grip and maybe a bit more circumference.

SOURCE: printer says there is a paper jam

Hello there There is some thing stoping it moving so better try this.
You may not see a paper jam.

This may work for you, it has worked for many here I given this advice so gave it a try it could work for you. Generally when this happens, something has fallen into the printer, or a piece of paper has been jammed in there.

First step, remove the ink cartridge, and turn the printer upside down and gently shake it, see if anything comes out.

If nothing goes, or you can't hear anything rattling around, get a piece of cardstock paper (60lb or heavier) and gently push this through the printer, to see if it will help push out what might be stuck in there.
And gave the rode that the ink slides on a good clean and maybe a bit oil on cloth and wipe the rod with it.

Also clean The purge unit, called a spittoon assembly in an HP, Lexmark, Caonon and other inkjet printers, is where the print head assembly parks when not in use, also its other job is to clean and make sure the print head is clean and open for printing.

That is where you'll find the print head assembly parked on top of it.
It also has an electrical pump to milk the print heads and test for ink flow.

So clean all under where the heads are parked and on IP6600D models you can take out the heads just by clipping them out, and then clean well.


Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
