No, if the scanner doesn't show any sign of life then either it's not powered (the power supply has died) or the unit itself has died.
To check which is easy: all you have to do is to plug the power source in the mains and check if it delivers the voltage at the jack - test it with a voltmeter.. If it doesn't then you need a new source, if it does then you need a new scanner.

Ricoh IS760D Functional Problem SC4020


Unfortunately, the message indicates that the internal startup tests have failed. If this unit is just past the warranty period, I would contact the manufacturer anyway and complain. No unit should fail that close to the period conclusion especially with little to no use. It is possible that a brown-out may have damaged the internal logic. Only a service tech for the company could tell you that. The blinking lights are an indication of the problem found. Report that to the company as well.
Good luck. Keep us posted.

My mp160 printer/scanner has no power when on switch is operated. Does this printer have an internal fuse and if so how do i get at it? The power cord tests OK.


the fuse is located at the power supply board which you will need to dis assemble the unit using with a phillip screw driver.unscrew to remove the cover and to access the power supply board . if the fuse is blown you need to check other component if defective since the fuse is blown. like shorted regulator, bridge diode and transistor.if you think you can not do the job just send it to the canon service center to fix the problem.

Internal fuse blew and is soldered in and I can't read what is the voltage and amperage of the internal fuse on the circuit board?


The ratings are normally stamped into the end caps of the fuse. Sometimes they are a bit hard to see. Make sure you repair the cuase of the failure before replacing.

My scanner bc350a will not turn on was working is there a fuse somewhere inside of the unit


There's a fuse in line with the DC (vehicle) cord, but none for AC power operation. Check the power supply with a voltmeter to be sure it's outputting power to the scanner (As a alternate, check the unit on vehicle power). If there's no output you can purchase a replacement power supply from Uniden on line of from other sources - such as eBay. If the power supply is outputting power, but the scanner is still not working, your problem could be the power connection at the scanner (internal or external), the power switch, or a myriad of other problems.

What happens if ur scanner has been hit by lighting?>


A power surge such as a nearby lightning strike can easily "fry" the circuitry in a scanner, leaving you with nothing more than a paperweight. Most have no circuit breaker and no internal fuse to protect them. Sorry.

Plugged in but no power?


I would recomend checking the fuse in the wire or plug you are using, if that is good i would then take a test light and check the power to my leads, most scanners operate on a 12volt source with a small inline fuse, so just check all the voltage and grounds good.

HP 4070 Doesn't Power Up


Power requirement per HP specs is 12VDC @ 575mA 6.9w. My scanner and power supply shows 12 VDC @ 1250ma.Over double the power going in that required. No wonder the fuse blows and you have to buy a new scanner because you can't identify or get a replacement fuse. I would suggest you confront HP and have them supply you with a new scanner.
