HP Envy 120 Scanner Fault

[jt26]

My HP Envy 120 is producing pages of vertical coloured lines when I try to scan or copy. No light comes on when scanning sensor moves. I have exhausted the possibilities that I can try myself and believe I need a semi-full programming reset as mentioned on other entries in this forum. Any help appreciated, printer is only 18 months old and has been good up to today.

Hi @jt26, 

Based on your description, it sounds like the scanner bulb has failed and you have mad every effort to resolve the issue with no luck. I suggest calling us to discuss you out of warranty options.

What you can do, is use the following link to create yourself a case number, then call and it may help speed up the call process:

Step 1. Open link: www.hp.com/contacthp/
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options - click on Get phone number

Case number and phone number appear.

 

Feel free to post again if there is anything else I can help you with.

Obviously, this problem is still around...unnecessarily!

The solution that works PERFECTLY was posted by Bettina 22 back in 2014. I can't take credit but I have tried it several times without error. A shame HP could not have passed this along over the past 2 years. I cleaned it up with a little more detail, but I cannot take ownership of the solution.

Thanks Bettina 22!

TO BEGIN: UNPLUP THE UNIT FROM THE POWER CORD AT REAR OF PRINTER

1. Use #10 Torx driver
2. Remove 2 screws AT LEFT AND RIGHT BOTTOM OF THE GLASS TOP OF PRINTER SCANNER
3. Pull glass from the back of the unit UP and SLIGHTLY OUT about enough to get your finger in to support the scanning bar which is connected to a “rail” on the back side of the top.

• Pull up the glass while supporting thescanning bar up and away from the base, jiggle the bar a bit and then reassemble THE BAR IN PLACE AGAIN FLUSH WITH THE SIDE. Push front of glass into place and then gently dropping the back of the glass into the top of unit. Make sure the scanning cables are inside the glass before placing glass completely down. KEY: SCANNING BAR MUST BE FLUSH WITH THE SIDE.

1. Mount just the right screw, PLUG IN THE UNIT WITH ITS POWER CORD AT REAR, reconnect it to your computer, and use the printer to do a scan to your computer. Run another scan to a USB device.
2. If successful, it is fixed!
3. Without shutting the printer off, lift the top and check the left hole to make sure it is unobstructed and can receive the holding screw. Screw in the left screw.
4. IT WORKS!

1. If the cable ends up blocking the left hole, do another scan and prepare to remove the power cord when the scanning bar is fully extended.
2. Remove the right screw and lift the glass just enough to get a small flat screwdriver between the glass and the top to move the FLAT cable out of the way of the screw hole.
3. Drop the glass back into the top and put the left screw in first if the cable is out of the way.

• KEY IS THAT THE SCANNING BAR MUST BE FLUSH WITH THE SIDE!

1. Replace the right screw and REINSERT THE POWER CORD.
2. The scanning bar should return to the left side of the unit.
3. Do another scan and, if OK, you are done.

It's really not that hard. My cost to fix was $6.95 for a #10 torx screwdriver. Now scans perfectly!

Good luck!

I've been repairing computers for a living for 40 years, so I thought I'd try the bettina22/formic fix. 

BIG mistake! 

Once you pull the glass, the scanner cannot be re-assembled without cracking the glass or crushing the ribbon cable.

I have long known that HP designs their equipment so that it is not repair-technician friendly .   With the 120, they have raised the bar to a new level.. We can only speculate on their reasoning.
