I have a HP deskjet 6122. The printer will not turn on at all. I checked the cord with an amp probe and it reads 120 volts. I cannot figure out how to take it apart to check the main on/off switch. Maybe this is not the problem. I found two screws on top next to the lid. I removed them but still the case will not come off.

The Deskjet 6122 uses soft power on and off, meaning the power switch does not actually disconnect power, but only puts the electronics in the stand-by mode. The power supply outputs 18 VDC and 32 VDC, as I recall (check the fine print on the power supply), which is present anytime AC power is applied.
I have my doubts that the power switch is bad unless you spilled something on it. The switch module may be shared with the Deskjet 3820. There are lots of dead 3820s around that can be used for parts if the module is identical. If you actually need a new module, I can make some comparisons in the shop and tell you for sure.
If the power supply has failed, be aware that HP does not offer it as a spare part. I nearly lost my mind trying to find repair components. (Maybe it will just be a blown fuse.) The power supply of course was made offshore and that seems to be where all of the spare parts are. If the power supply has failed, I have some sources that may be able to do the repair, but it ain't cheap.
Deskjet 6122, Removing the case 1. Remove the small case piece on each side of the paper tray. There is small latch on each, releasable from the underside of the printer. 2. Remove the two T10 Torx screws on the top of the case. Pry upward with a slot style screwdriver under the tab that each screw went through, and the associated side piece will hinge outward and come off. Free the right side piece by releasing the latch that retains the keypad. 3. Open the hinged cover and release the large latch in front of the service station with a slot style screwdriver. Release the latch on the opposite side in the same relative position, and the main case will lift off

The sample I have has a radial leaded cylindrical fuse approximately 8.2mm in diameter X 7.25mm high. It is soldered to the power supply board near where the AC comes in, and is designated as F1.

I have a Canon Bubblejet 200ex. The printer will not turn on at all. I checked the cord and even tried another new one but neither works. I plan to take it apart to check the main switch connection and hope this works but if anyone has any ideas please let me know.

After I open the back of my HP Deskjet F2210- and removed the paper that was stuck -- replaced the cords-- my printer will not turn on. What should I do to get it to turn on again?

I have an Epson Stylus CX6600 and it has similar problems. It took longer and longer to power up each morning. Now it wont go on at all. I have checked out the lead on another item and the plug with a radio door chime - all is well. I've taken out all visible screws to view the insids but it will not come apart. Anybody any ideas? jimW

I got a free HP deskjet Ink Advantage 2060 Printer from smartbro connection, and I've been using this for years. Til the ink runs out. Then I bought a new ink for this but my printer won't turn on now.. I don't think that my printer is broken because I was the only one who used this. And I am very much careful with my things. Please help.
