We need to know Brand and model
So you need to tell us you have a HP all in one laser printer/scanner first!
Clean the scanner head and glass
Removing the scanner glass(D145)
General
The Automatic Document Feeder (ADF) will need to be removed before the glass can be removed. You will also need a T10 Torx head driver approximately 6" long. Driver handles that accept removable bits may be too large in diameter for this particular job.
Removing the automatic document Feeder (ADF)
1. Hinge the ADF upward as if you are going to manually scan a document.
2. In the hinge area there is two black pull latches. Pull them up and lift the ADF straight up to remove it. Some side-to-side rocking may be necessary before it will disengage.
Removing the Scanner Glass
1. Remove the four T10 Torx head screws around the perimeter of glass, i.e. two in the ADF hinge area and one on the right and left.
2. Remove the Control Panel overlay. It pries off.
3. Open the printer as if you are going to access the cartridges and disengage the support legs. Two latches at the base of each leg must be pried outward with a slot style screwdriver to disconnect them. The scanner assembly will now "flop" freely, so steady it while removing the four screws on the underside.
Note: The screw in the front is hidden under the piece that you grasp to gain cartridge access. Two latches must be released to remove it. The screw can now be seen using a flashlight but may be obscured by some wires.
Clean the underside of the glass, giving particular attention to the white strip. Then clean the scanner bulb (gently, its thin glass) and the mirror(s) with a cotton swab sparingly moistened with Windex or a similar cleaner.

hp officejet d145 scanner failure
I have an HP OFFICEJET 7140xi with the same problem.
Scanner failure, switch off and switch on again'
Tried this it works for a short time then fails again. Any permanent cure please?
Machine will not Fax either from glass or through document feeder. Failure message directs power turn off, then on. Still will not work. Technician recommends direct plug in to wall. This solution doesn't work, either.
I have the PSC 750 printer and I keep getting "scanner failure' when I try and scan or copy. I turn it off and then back on as it says, but I still get the error message. It seems that if I unplug it and wait at least 2 minutes, it will sometimes work for a couple of times, but then the same thing happens. I have tried re-dowloading the drivers with no resolve to this problem.
