Officejet 7310: Scanner Failure

My machine is out of warranty. From the beginning it has had issues with scanning but now even printing results in a "scanner failure." The cost to have HP fix it just doesn't seem like a smart investment. I was hoping someone could tell me what the part is and whether a savvy tech person could swap it out. It apears to be a hardware issue but no idea how to fix it. From the boards,this seems to be a popular issue with this product.

Any thoughts?

    HP Officejet 7310 displays "Scanner failure" whenever we try
    to fax. The print, scan, and copy features work very well. When the fax
    is started, it dials out, then the printer cartridge travels midway of
    the glass, stops, gives a horrible "whrrrr" sound, and then the display
    reads "Scanner failure" & indicates that the power should be turned
    off. We followed all the instructions online for the partial reset,
    full reset, cleaned the glass, and the scanner bulb is just fine.





    I
    s there a software download or hardware repair to fix this problem?We've looked at several forums online and none have a workable solution.

    Note that the steps from HP's on-line chat w/ a technician were useless (provided below):





    Let us power cycle the unit using the below steps.
    1. Verify that the unit is switched on. Disconnect the USB/Ethernet
    cable from the All-in-One and also disconnect power cable from
    All-in-One and also from wall outlet.

    2. Wait 30 seconds.

    3. Plug in the power cable to All-in-One and also to wall outlet.

    I'm on my second 7310 and I really don't buy the excuse that I have bad power. HP should design products have tolerance for different power conditions. I live in major US city with clean power, so this is not a valid explaination.

If you get a "Scanner failure" message then the problem is the motor itself. Notice how the motor works fine when the scanner is moving slowly, like copies or faxing with the original laid on the glass. HOWEVER, the scanner failure comes up when you use the automatic document feeder on top. Why? Because the scanner assembly has to move to the other side of the printer at high speed to get into position, and it's the high speed movement that triggers the error on the printer. The motor is expensive, part number Q3450-60003. Many other models use the same motor, maybe you could find one cheap somewhere and swap the motor?

I have fixed this. There are 2 Scanner Failure problems.

The first one is a defective Scanner motor. Usually the printer will get to a ready status. Then when trying to fax or copy from the ADF, you get Scanner Failure. If the motor is bad it usually messes up when the scan head has to shoot to the other side of the glass for an ADF scan. Solution is to replaced the scanner motor.

Second and more common is the scan head cannot find it's home position. Usually the printer will error out with a Scanner failure while initializing before you get to the ready screen. You can hear the scan head hit the right side once or twice then error. On the UNDERSIDE of the glass to the right is a white strip. This is where the scan head sits when resting. This is also the home position. An engineer stated that the black sticky strip which holds the white strip to the glass will shrink over time due to excessive heat. This causes excess light to refract through the glass thus giving a FALSE home position. The scanner hits the wall thinking the white strip is more to the right. To fix this you must remove the glass, flip it over, and between the white strip and long edge of the glass paint it black with a permenant marker. DO NOT COVER THE WHITE. paint between the white and the edge of the glass. This will stop the light from refracting. Scan head should now find it's home position.

These are Common and normal issues with these models. Hope this helps.

Sometimes (not always) scanner failures are caused by power deficiency. Generally this is a result of using the wrong power supply or if the power supply is damaged. Look over your power cord if you spot any damage. Also check to make sure the volt/amp output printed on the power supply matches your printer requirements (you can usually find this on the back or the bottom of the printer). If the voltage and amps aren't the same (or close) then your cord is the problem.

If it isn't the cord then it's more then likely your scanner bulb. And while it is possible to replace that part on your own I wouldn't suggest it unless you're used to working on printers.

Sometimes you can clean the scanner optics and get a little more life from it, but it involves taking the glass off the top and cleaning the scan unit mirrors and lenses. When that doesn't work you need to locate a new scan assembly, last check, around $150.00

Scanner failure-no longer prints


Hi, I'll give your situation a "stab in the dark" solution. It sounds like you are in the final stages of "scanner system failure". The beginning stages usually limits the all-n-1 to print only i.e., no scan and no fax but you may have such a severe scanner bulb situation that is preventing the print function and may be causing hazardous conditions within your printer and it will do nothing to prevent further harm or damage. Can you describe your situation a bit more detailed?

HP 7310 All-In-One giving a dark line one scans and copies


I had the same problem but figured it out. Both sections of the top of the printer open and under the left side there is a separate "scanner window" that you can't see unless you open that side. lift your regular scan tray and then pull the left side up (it opens out to the left) and then left the piece that is under it. You should be able to see the thin scanner window. You can clean it with rubbing alcohol or even windex.
