HP Scanjet 4890: How to repair the scanner light?

Fri, 27 Feb 2026 19:31:11 -0700

I have this scanner and it appears to be physically operable except for the light, which does not turn on when scanning. Software on the computer detects the scanner, sends instructions to begin scanning, the platen (?) moves across under the glass and "data" is received. But without the light, the data is just a blank page.

Any pointers to maintenance manuals or instructions to repair would be very helpful.

NeatDesk™ Desktop Scanner: Gray band on one side of Scan

Sun, 04 Jan 2026 20:22:05 -0700

My neat desk scanner still basically works fine but repeatedly there is either a gray band on the left side of the front page or that same band is simply a poor scan.

Cleaning sand recalibrations sometime will correct the problem for a day or two and then it returns. Reloaded software and drivers but no effect .

By the way I use mine on Macbook pro.

Any Ideas? Neat support is so unhelpful and mostly unresponsive.

Thanks.

I can buy the rollers from Fujitsu, but they will not give me the instructions on how to disassemble and reassemble the machine to replace them. These are the small gold rollers, not the large grey rollers. If anyone has done this, please let me know how you did it.

Nikon Coolscan IV ED: My scanner makes a fast clicking noise and won’t turn on

Mon, 30 Jun 2025 11:19:23 -0700

The scanner won’t turn on after being plugged into the wall, instead it only makes a constant clicking noise like something’s zapping. It remains clicking for a second or two after unplugging it so it might be a capacitor issue but I’m not pro with these devices.

NeatDesk™ Desktop Scanner: Scan and pdf led's both light on power up...non responsive

Thu, 13 Feb 2025 22:36:51 -0700

The main desktop scan unit "SCAN" and "PDF" LED's found on the desktop scanner body both light green upon power up. The led buttons are not jammed. Pushing the buttons will not change the lights. Adding paper does not help. Toggling the outside on off switch does not help. Plugging the USB wire into the unit and connecting to a computer does not have any effect. The computer runs Neatworks version 5.4 and now 5.7. Toggling on the soft "scan" button in software results in gettingt a message that the scanner is not available. No amount patient switching on or off the button helps. There is no reset button visible. The unit has no fractures or loose parts within. I have poked about and pulled off the plastic paper feeder sheets to see if there is a roller/feed jam but can find nothing. There is a plastic carrier bar inside the lid of the unit. It is not jammed. it springs back and forth a bit in a normal fashion when I push on it. The unit is not yet disassembled. Recollection indicates the unit may have been dropped recently on a soft wooden floor from desk level but there is no outward sign of damage. I suspect a loose connection somewhere within. But maybe others have some experience at this effort to unjam the machine before I attack it.

Scanner: How do you change the glass on an Epson Perfection V600 Photo Scanner

Sat, 08 Feb 2025 09:49:58 -0700

How do you change the glass on an Epson V600 Scanner? The repair for the broken hinge was very helpful in removing the lid and locating the screws to remove the glass assembly. It also recommends leaving the ribbon cable attached, but to change the glass assembly will require the removal of the switches in the front of the machine. It looks like the ribbon cable is attached to those switches. So does the ribbon cable need to be disconnected? If so is there anything special I need to know to disconnect it? Or can the switches in the front of the glass assembly be removed leaving the ribbon cable attached to the switches. Any suggestions would be helpful.

Thanks,

Mike

ScanSnap iX500: An error in the optical system

Sun, 10 Mar 2024 15:13:03 -0700

I have a ScanSnap iX500. I am getting a message from the ScanSnap manager which says, "An error in the optical system". I have tried all of the suggestions for resolving the issue which included cleaning the glass inside the scanner, and everything else that was suggested in the problem-solving suggestions. However, none were successful, and I am still unable to scan and keep getting above mentioned message. I am looking for a local repair shop in the Miami Florida area ZIP Code 33155 where I could take my scanner to be fixed. Can anyone suggest a repair shop.

Epson WorkForce DS-510: Jams when scanning Drivers License

Thu, 07 Mar 2024 14:07:46 -0700

We use the DS 510 in our medical office. The scanner used to scan both Insurance cards and photo ID's with no problem, but recently it jams on only the Drivers License photo ID. I have looked and found no mechanical issues. If we place the ID longways in the scanner it will scan, but then we spend extra time rotating the ID for our files. Time consuming. Any suggestions?

Things I have tried:

Adding post it to the back side of the ID - still jams

Moving the mult page and cont feed button - still jams
