The easiest way to get the springs back in is to place the print head back into the carriage assembly, then start from the back and stretch it to the front. The best way to describe it it a pice of plastic on the back of the print head, a small gap underneath it, and then another piece. ONCE AGAIN TAKE NOTE: You will get a "Carriage Jam" Error if you do not place the print head back in with the dark ribbon that goes across the printer BETWEEN the small sensor on the back of the print head. Reverse the disassembly order to put the printer back together. (I soaked and cleaned twice.) Gently shake the excess water out onto a few paper towels and let it sit for a minute or so. Change out the water and repeat until you're satisfied. Use a coffe filter to clean the print head after soaking for about 30 seconds.

DO NOT GET THE SMALL PC BOARD WET!!!! DO NOT GET WATER ONTO/INTO THE PORTS WHERE THE INK CARTRIDGES GO. What I did was got a small bowl of hot (not boiling) water and carefully placed the print head in it, just enough to soak the bottom. The dark ribbon interacts with a sensor on the back of the printhead to determine its placement within the printer.ĭo not use alcohol or any amonia based cleaners to clean the print head. You will get a CARRIAGE JAM ERROR if you do not put it back properly. NOTE: The placement of the dark ribbon that goes across the printer and how it is slipped into the back of the print head. NOTE: The springs are attached big end on the print head assembly, the small ends on the carriage assembly. CAREFULL! There are 3 ribbons on the back of the print head assembly! Remove the springs and the ribbons. It may be easier to do it one side at a time. To remove the print head assembly, you need to squeeze the tabs and gently remove it. At this point, you can move the carriage assembly to the left towards the center. Then remove the lid itself by lifting up.Ħ. Remove them all and don't forget the ones in the back.

You will see a series of screws along the top perimeter of the cover. Oce you have it unhooked, open the lid all the way it can go and let it be.ĥ. It may be easier if the lid is not fully opened, and it will give a little resistance.

Unhook it at the lid by pulling it towards the front of the printer. With the lid still open, on the right side, there is a hinge that is hooked to the lid that goes under the cover of the printer. You will notice 2 silver screws under the control panel, left and right. Careful!! There is a ribbon attached to it that must be removed safely. There will be some resistance, but it shouldn't break. If you open the printer lid (as you would if replacing ink cartridges) and look from behind (flashlight needed), you'll see a little snap, simply press it down with one hand and remove the panel with the other starting from the left, and then right. Remove the sticker that has the model number on the cover, towards the right of the printer. I was able to remove the print head!

Hopefully some of you OP's will get some use from it, but perhaps some of those searching this forum for answers will also. Hey guys, I know this thread is a little old. I am only giving these steps to help those people out that are about to trash a decent printer. I am not responsible for any damage caused by YOU taking your printer apart. Performing this disassembly will void your warranty if it has not already expired.
